Background: The Virginia Uniform Statewide Building Code (USBC) governs the construction, maintenance, and rehabilitation of new and existing buildings and structures. The USBC uses nationally recognized model building codes and standards produced by the International Code Council and other standard-writing groups as the basis for the technical provisions of the regulation. Every three years, new editions of the model codes become available. At that time, the Board of Housing and Community Development initiates a regulatory action to incorporate the newest editions of the model codes into regulation through the publishing of a proposed regulation. Those affected by the regulation review the proposed regulation to assure that the newest model codes and standards reflect the minimum requirements necessary for buildings and structures. After publication of the proposed regulation, the board establishes a comment period for the acceptance of comments on amendments reflected in the proposed regulation and a public hearing is held. The board then considers comments on all proposals and develops a final regulation to complete the regulatory process.

Summary:

The substantive amendments in this regulatory action include the following:

13VAC5-63-20 D (8): Adds "Off-site manufactured intermodal freight containers, moving containers, and storage containers placed on site temporarily or permanently for use as a storage container" to the exemptions from this code.

13VAC5-63-20 D (9): Adds "Automotive lifts" to the exemptions from this code.

13VAC5-63-30 G: Deletes existing language and adds language that requires compliance with the Virginia Rehabilitation Code (VRC) as related to reconstruction, alteration, and repairs in occupancies other than Group R-5.

13VAC5-63-80 B (12): Adds crypts, mausoleums, and columbaria structures to exemptions from application for permit.

13VAC5-63-120 A through X: These provisions were approved under a prior action of the board under special provisions for defective materials and were only effective for two years. This action will make the provisions a permanent part of the USBC.

13VAC5-63-170 B: Adds this subsection for temporary uses within existing buildings and structures; allows the building official to approve conditions or modifications for temporary use; and stipulates that the building official shall notify the fire official of the approved temporary use and is allowed to terminate the approval.

13VAC5-63-180 D (new E): Deletes some existing language applicable to vacating unsafe buildings or structures and clarifies that the building official is authorized to order the building or structure to be vacated immediately if there is imminent danger to the occupants or to the public.

13VAC5-63-210 E: Changes Section 308.2 to Section 308.3 of the IBC for Institutional Group I-1; excludes residing staff from the number of persons residing on a 24-hour basis who receive custodial care; specifies section to be referenced for Group I-1, other than assisted living facilities as Section 308.3.1; specifies assisted living facilities be classified as one of the occupancy conditions indicated in Section 308.3.1 or 308.3.2; clarifies the exception for Group I-1 occupancies as the occupancy condition indicated in Section 308.3.1; and deletes language that refers to a similar facility with five or fewer persons.

13VAC5-63-210 R 28 (new 27): Deletes the use of Appendix G for swimming pools, spas, and hot tubs. Swimming pools, as defined in the USBC, shall comply with the applicable provisions of the International Swimming Pool and Spa Code.

13VAC5-63-210 R 52 (new 43): Deletes all existing language and adds new language to Section R602.12 for practical wall bracing, which allows all buildings in Seismic Design Categories A and B and detached buildings in Category C to be permitted to be braced in accordance with this section as an alternative to Section R602.10. The revisions also add several sections relating to wall bracing requirements and procedures.

13VAC5-63-210 R (53): Changes Section N1102.4.1.2 (R402.4.1.2) for air sealing and requires compliance with either Section N1102.4.1.2.1 or Section N1102.4.1.2.2 and adds sections that (i) specify how the testing option shall be performed when testing for air leakage; (ii) provide that visual inspection is an option for air leakage compliance; and (iii) state that the air leakage rate shall not exceed five changes per hour.

13VAC5-63-210 R (56): Changes Section N1103.2.2.1 (R403.2.2.1) for testing options. Clarifies that the post-construction test shall be determined by the total leakage that is less than or equal to 6 cfm/100 square feet across the entire system; clarifies that the rough-in test shall be determined by the total leakage that is less than 5 cfm/100 square feet across the system; addresses the case where the air handler has yet to be installed, in this case the total leakage shall be less than or equal to 5 cfm/100 square feet; and revises the exception to indicate that the total leakage test not be required for ducts and air handlers located entirely within the building thermal envelope.

13VAC5-63-210 R (57): Adds Section N1103.2.2.2 (R403.2.2.2) for visual inspection option for compliance.

13VAC5-63-210 R (72): Adds Sections P2909.1 through P2909.18, including subsections for scope and design of nonpotable water systems, makeup water, makeup water sources, makeup water supply valves, control valve alarms, sizing, required signage, potable water supply system connections, nonpotable water system connections, approved components and materials, insect and vermin control, freeze protection, nonpotable water storage tanks, inlets, outlets, materials and location, foundation and supports, ballasts, structural support, overflow, access, venting, drains, storage tank tests, structural strength, trenching requirements, outdoor outlet access, drainage and vent piping fittings, pumping and control systems, water-pressure reducing valves or regulators, distribution pipes, materials, joints, and connections, design, labeling and marking, backflow prevention, tests and inspections, drainage and vent pipe tests, storage tanks tests, water supply system tests, inspection and testing of backflow prevention assemblies, inspection of vermin and insect protection, and operation and maintenance manuals.

13VAC5-63-220 M: Adds Section 425.2.1 to the IBC for relocated manufactured homes, which specifies that installation, setup, and site work shall comply with the provisions of this code and shall include the option of using the manufacturer's installation instructions or the federal Model Manufactured Home Installation Standards (24 CFR Part 3285) for the technical requirements.

13VAC5-63-220 N: Adds Section 425.2.2 to the IBC for alterations and repairs to manufactured homes, which specifies that alterations and repairs shall be in accordance with federal Manufactured Home Construction and Safety Standards (24 CFR Part 3280) or in accordance with the alteration and repair provisions of this code.

13VAC5-63-310 D (3), (4), and (5): Amends the IMC to permit residential-type electric stoves to be used in commercial buildings without the need of a commercial exhaust hood.

13VAC5-63-310 D (6) and (7): Modifies the IMC to permit water quality for cooling towers to be in accordance with the equipment manufacturer's recommendations to safely permit the use of rainwater or other nonpotable water sources in air-conditioning systems.

13VAC5-63-330 B: Amends the elevator chapter of the IBC to correlate with requirements for fire service elevator keys established in the IFC, which permit the use of either a standardized key or the use of a lock box for a non-standardized key.

13VAC5-63-350: Addresses existing buildings and contained provisions to be used for alterations, additions, and change of occupancy to existing buildings as well as setting out special retrofit requirements for existing buildings when required by state law. All requirements in this section have been moved to Part II of the regulation (the VRC) so there remains a provision that deletes all of Chapter 34 of the IBC, as it is no longer used.

13VAC5-63-410 B: Changes the scope of the VRC to include mandatory requirements for the alteration and repair of buildings and for changes of occupancy in existing buildings, except for buildings in the Institutional grouping, where Part I of the regulation still applies and clarifies that the VRC may be used for alterations to residential buildings as an acceptable alternative to the use of Part I of the regulation.

Part I
Construction

13VAC5-63-10. Chapter 1 Administration; Section 101 General.

A. Section 101.1 Short title. The Virginia Uniform Statewide Building Code, Part I, Construction, may be cited as the Virginia Construction Code or as the VCC. The term "USBC" shall mean the Virginia Construction Code VCC unless the context in which the term is used clearly indicates it to be an abbreviation for the entire Virginia Uniform Statewide Building Code or for a different part of the Virginia Uniform Statewide Building Code.

Note: This code is also known as the 2009 2012 edition of the USBC due to the use of the 2009 2012 editions of the model codes.

B. Section 101.2 Incorporation by reference. Chapters 2 - 35 of the 2009 2012 International Building Code, published by the International Code Council, Inc., are adopted and incorporated by reference to be an enforceable part of the USBC. The term "IBC" means the 2009 2012 International Building Code, published by the International Code Council, Inc. Any codes and standards referenced in the IBC are also considered to be part of the incorporation by reference, except that such codes and standards are used only to the prescribed extent of each such reference. In addition, any provisions of the appendices of the IBC specifically identified to be part of the USBC are also considered to be part of the incorporation by reference.

Note 1: The IBC references the whole family of other International Codes and standards including the following major codes:

2009 2012 International Plumbing Code (IPC)

2009 2012 International Mechanical Code (IMC)

2008 2011 NFPA 70

2009 2012 International Fuel Gas Code (IFGC)

2009 2012 International Energy Conservation Code (IECC)

2009 2012 International Residential Code (IRC)

Note 2: The International Residential Code IRC is applicable to the construction of detached one- and two-family dwellings and townhouses as set out in Section 310.

C. Section 101.3 Numbering system. A dual numbering system is used in the USBC to correlate the numbering system of the Virginia Administrative Code with the numbering system of the IBC. IBC numbering system designations are provided in the catchlines of the Virginia Administrative Code sections. Cross references between sections or chapters of the USBC use only the IBC numbering system designations. The term "chapter" is used in the context of the numbering system of the IBC and may mean a chapter in the USBC, a chapter in the IBC or a chapter in a referenced code or standard, depending on the context of the use of the term. The term "chapter" is not used to designate a chapter of the Virginia Administrative Code, unless clearly indicated.

D. Section 101.4 Arrangement of code provisions. The USBC is comprised of the combination of (i) the provisions of Chapter 1, Administration, which are established herein, (ii) Chapters 2 - 35 of the IBC, which are incorporated by reference in Section 101.2, and (iii) the changes to the text of the incorporated chapters of the IBC that are specifically identified. The terminology "changes to the text of the incorporated chapters of the IBC that are specifically identified" shall also be referred to as the "state amendments to the IBC." Such state amendments to the IBC are set out using corresponding chapter and section numbers of the IBC numbering system. In addition, since Chapter 1 of the IBC is not incorporated as part of the USBC, any reference to a provision of Chapter 1 of the IBC in the provisions of Chapters 2 - 35 of the IBC is generally invalid. However, where the purpose of such a reference would clearly correspond to a provision of Chapter 1 established herein, then the reference may be construed to be a valid reference to such corresponding Chapter 1 provision.

E. Section 101.5 Use of terminology and notes. The term "this code," or "the code," where used in the provisions of Chapter 1, in Chapters 2 - 35 of the IBC or in the state amendments to the IBC means the USBC, unless the context clearly indicates otherwise. The term "this code" or "the code" where used in a code or standard referenced in the IBC means that code or standard, unless the context clearly indicates otherwise. The use of notes in Chapter 1 is to provide information only and shall not be construed as changing the meaning of any code provision. Notes in the IBC, in the codes and standards referenced in the IBC and in the state amendments to the IBC may modify the content of a related provision and shall be considered to be a valid part of the provision, unless the context clearly indicates otherwise.

F. Section 101.6 Order of precedence. The provisions of this code shall be used as follows:

1. The provisions of Chapter 1 of this code supersede any conflicting provisions of Chapters 2 - 35 of the IBC and that address the same subject matter and impose differing requirements.

2. The provisions of Chapter 1 of this code supersede any conflicting provisions of the codes and standards referenced in the IBC that address the same subject matter and impose differing requirements. In addition, the

3. The state amendments to the IBC supersede any conflicting provisions of Chapters 2 - 35 of the IBC and that address the same subject matter and impose differing requirements.

4. The state amendments to the IBC supersede any conflicting provisions of the codes and standards referenced in the IBC that address the same subject matter and impose differing requirements. Further, the

5. The provisions of Chapters 2 - 35 of the IBC supersede any conflicting provisions of the codes and standards referenced in the IBC that address the same subject matter and impose differing requirements.

G. Section 101.7 Administrative provisions. The provisions of Chapter 1 establish administrative requirements, which include but are not limited to provisions relating to the scope of the code, enforcement, fees, permits, inspections and disputes. Any provisions of Chapters 2 - 35 of the IBC or any provisions of the codes and standards referenced in the IBC that address the same subject matter and impose differing requirements are deleted and replaced by the provisions of Chapter 1. Further, any administrative requirements contained in the state amendments to the IBC shall be given the same precedence as the provisions of Chapter 1. Notwithstanding the above, where administrative requirements of Chapters 2 - 35 of the IBC or of the codes and standards referenced in the IBC are specifically identified as valid administrative requirements in Chapter 1 of this code or in the state amendments to the IBC, then such requirements are not deleted and replaced.

Note: The purpose of this provision is to eliminate overlap, conflicts and duplication by providing a single standard for administrative, procedural and enforcement requirements of this code.

H. Section 101.8 Definitions. The definitions of terms used in this code are contained in Chapter 2 along with specific provisions addressing the use of definitions. Terms may be defined in other chapters or provisions of the code and such definitions are also valid.

Note: The order of precedence outlined in Section 101.6 may be determinative in establishing how to apply the definitions in the IBC and in the referenced codes and standards.

Any state-owned building or structure for which preliminary plans were prepared or on which construction commenced after the initial effective date of the USBC, shall remain subject to the provisions of the USBC that were in effect at the time such plans were completed or such construction commenced. Subsequent reconstruction, renovation or demolition of such building or structure shall be subject to the pertinent provisions of this code.

Acting through the Division of Engineering and Buildings, the Virginia Department of General Services shall function as the building official for state-owned buildings. The department shall review and approve plans and specifications, grant modifications, and establish such rules and regulations as may be necessary to implement this section. It shall provide for the inspection of state-owned buildings and enforcement of the USBC and standards for access by the physically handicapped by delegating inspection and USBC enforcement duties to the State Fire Marshal's Office, to other appropriate state agencies having needed expertise, and to local building departments, all of which shall provide such assistance within a reasonable time and in the manner requested. State agencies and institutions occupying buildings shall pay to the local building department the same fees as would be paid by a private citizen for the services rendered when such services are requested by the department. The department may alter or overrule any decision of the local building department after having first considered the local building department's report or other rationale given for its decision. When altering or overruling any decision of a local building department, the department shall provide the local building department with a written summary of its reasons for doing so.

Notwithstanding any provision of this code to the contrary, roadway tunnels and bridges owned by the Virginia Department of Transportation shall be exempt from this code. The Virginia Department of General Services shall not have jurisdiction over such roadway tunnels, bridges and other limited access highways; provided, however, that the Department of General Services shall have jurisdiction over any occupied buildings within any Department of Transportation rights-of-way that are subject to this code.

Except as provided in subdivision D of § 23-38.109 D of the Code of Virginia, and notwithstanding any provision of this code to the contrary, at the request of a public institution of higher education, the Virginia Department of General Services, as further set forth in this provision, shall authorize that institution of higher education to contract with a building official of the locality in which the construction is taking place to perform any inspection and certifications required for the purpose of complying with this code. The department shall publish administrative procedures that shall be followed in contracting with a building official of the locality. The authority granted to a public institution of higher education under this provision to contract with a building official of the locality shall be subject to the institution meeting the conditions prescribed in subdivision B of § 23-38.88 B of the Code of Virginia.

Note: In accordance with § 36-98.1 of the Code of Virginia, roadway tunnels and bridges shall be designed, constructed and operated to comply with fire safety standards based on nationally recognized model codes and standards to be developed by the Virginia Department of Transportation in consultation with the State Fire Marshal and approved by the Virginia Commonwealth Transportation Board. Emergency response planning and activities related to the standards approved by the Commonwealth Transportation Board shall be developed by the Department of Transportation and coordinated with the appropriate local officials and emergency service providers.

A. Section 104.1 Scope of enforcement. This section establishes the requirements for enforcement of the USBC in accordance with § 36-105 of the Code of Virginia. Enforcement of the provisions of the USBC for construction and rehabilitation shall be the responsibility of the local building department. Whenever a county or municipality does not have such a building department, the local governing body shall enter into an agreement with the local governing body of another county or municipality or with some other agency, or a state agency approved by DHCD for such enforcement. For the purposes of this section, towns with a population of less than 3,500 may elect to administer and enforce the USBC; however, where the town does not elect to administer and enforce the code, the county in which the town is situated shall administer and enforce the code for the town. In the event such town is situated in two or more counties, those counties shall administer and enforce the USBC for that portion of the town situated within their respective boundaries.

Upon However, upon a finding by the local building department, following a complaint by a tenant of a residential rental dwelling unit that is the subject of such complaint, that there may be a violation of the unsafe structures provisions of Part III of the Virginia Uniform Statewide Building Code, also known as the "Virginia Maintenance Code," or the "VMC," the local building department shall enforce such provisions.

If the local building department receives a complaint that a violation of the Virginia Maintenance Code VMC exists that is an immediate and imminent threat to the health or safety of the owner or, tenant, or occupants of a residential dwelling unit or a nearby residential dwelling unit, and any building or structure, or the owner, occupant, or tenant or any nearby building or structure, and the owner, occupant, or tenant of the residential dwelling unit building or structure that is the subject of the complaint has refused to allow the local building official or his agent to have access to the subject dwelling building or structure, the local building official or his agent may present sworn testimony to a magistrate or a court of competent jurisdiction and request that the magistrate or court grant the local building official or his agent an inspection warrant to enable the building official or his agent to enter the subject dwelling building or structure for the purpose of determining whether violations of the Virginia Maintenance Code VMC exist. The local building official or his agent shall make a reasonable effort to obtain consent from the owner, occupant, or tenant of the subject dwelling building or structure prior to seeking the issuance of an inspection warrant under this section.

The local governing body shall, however, inspect and enforce the provisions of the Virginia Maintenance Code VMC for elevators, escalators, and related conveyances, except for elevators in single-family and two-family homes and townhouses. Such inspection and enforcement shall be carried out by an agency or department designated by the local governing body.

B. Section 104.2 Interagency coordination. When any inspection functions under this code are assigned to a local agency other than the local building department, such agency shall coordinate its reports of inspection with the local building department.

C. 104.3 Transfer of ownership. If the local building department has initiated an enforcement action against the owner of a building or structure and such owner subsequently transfers the ownership of the building or structure to an entity in which the owner holds an ownership interest greater than 50%, the pending enforcement action shall continue to be enforced against the owner.

R602.10.1.4 Angled walls. Any portion of a wall along a braced wall line shall be permitted to angle out of plane for a maximum diagonal length of eight feet (2438 mm). Where the angled wall occurs at a corner, the length of the braced wall line shall be measured from the projected corner as shown in Figure R602.10.1.4. Where the diagonal length is greater than eight feet (2438 mm), it shall be considered a separate braced wall line and shall be braced in accordance with Section R602.10.1.

http://leg5.state.va.us/images/489835313418DHCDVH_files/image002.jpg

R602.10.2 Braced wall panels. Braced wall panels shall be full-height sections of wall that shall have no vertical or horizontal offsets. Braced wall panels shall be constructed and placed along a braced wall line in accordance with this section and the bracing methods specified in Section R602.10.4.

R602.10.2.1 Braced wall panel uplift load path. The bracing lengths in Table R602.10.3(1) apply only when uplift loads are resisted per Section R602.3.5.

R602.10.2.2 Locations of braced wall panels. A braced wall panel shall begin within 10 feet (3810 mm) from each end of a braced wall line as determined in accordance with Section R602.10.1.1. The distance between adjacent edges of braced wall panels along a braced wall line shall be no greater than 20 feet (6096 mm) as shown in Figure R602.10.2.2.

http://leg5.state.va.us/images/489898746023DHCDVH_files/image001.jpg

R602.10.2.3 Minimum number of braced wall panels. Braced wall lines with a length of 16 feet (4877 mm) or less shall have a minimum of two braced wall panels of any length or one braced wall panel equal to 48 inches (1219 mm) or more. Braced wall lines greater than 16 feet (4877 mm) shall have a minimum of two braced wall panels.

R602.10.3 Required length of bracing. The required length of bracing along each braced wall line shall be determined as follows.

1. All buildings in Seismic Design Categories A and B shall use Table R602.10.3(1) and the applicable adjustment factors in Table R602.10.3(2).

2. Detached buildings in Seismic Design Category C shall use Table R602.10.3(1) and the applicable adjustment factors in Table R602.10.3(2).

3. Townhouses in Seismic Design Category C shall use the greater value determined from Table R602.10.3(1) or R602.10.3(3) and the applicable adjustment factors in Table R602.10.3(2) or R602.10.3(4) respectively.

Only braced wall panels parallel to the braced wall line within the four foot (1219 mm) offset permitted by Section R602.10.1.2 shall contribute towards the required length of bracing of that braced wall line. If a braced wall panel is located along an angled wall and meets the minimum length requirements of Tables R602.10.5 or R602.10.5.2, it shall be permitted to contribute its projected length towards the minimum required length of bracing for the braced wall line as shown in Figure R602.10.1.4. If a braced wall panel is located along an angled wall at the end of a braced wall line, it shall contribute its projected length for only one of the braced wall lines at the projected corner.

Rehabilitation

13VAC5-63-400. Chapter 1 Administration; Section 101 General.

A. Section 101.1 Short title. The Virginia Uniform Statewide Building Code, Part II, Rehabilitation, may be cited as the "Virginia Rehabilitation Code," or as the "VRC."

B. Section 101.2 Incorporation by reference. Chapters 2 - 15 16 of the 2009 2012 International Existing Building Code, published by the International Code Council, Inc., are adopted and incorporated by reference to be an enforceable part of the Virginia Rehabilitation Code VRC. The term "IEBC" means the 2009 2012 International Existing Building Code, published by the International Code Council, Inc. Any codes and standards referenced in the IEBC are also considered to be part of the incorporation by reference, except that such codes and standards are used only to the prescribed extent of each such reference.

C. Section 101.3 Numbering system. A dual numbering system is used in the Virginia Rehabilitation Code VRC to correlate the numbering system of the Virginia Administrative Code with the numbering system of the IEBC. IEBC numbering system designations are provided in the catch-lines of the Virginia Administrative Code sections and cross references between sections or chapters of the Virginia Rehabilitation Code VRC use only the IEBC numbering system designations. The term "chapter" is used in the context of the numbering system of the IEBC and may mean a chapter in the Virginia Rehabilitation Code VRC, a chapter in the IEBC or a chapter in a referenced code or standard, depending on the context of the use of the term. The term "chapter" is not used to designate a chapter of the Virginia Administrative Code, unless clearly indicated.

D. Section 101.4 Arrangement of code provisions. The Virginia Rehabilitation Code VRC is comprised of the combination of (i) the provisions of Chapter 1, Administration, which are established herein, (ii) Chapters 2 - 15 16 of the IEBC, which are incorporated by reference in Section 101.2, and (iii) the changes to the text of the incorporated chapters of the IEBC that are specifically identified, including any new chapters added. The terminology "changes to the text of the incorporated chapters of the IEBC that are specifically identified, including any new chapters added" shall also be referred to as the "state amendments to the IEBC." Such state amendments to the IEBC are set out using corresponding chapter and section numbers of the IEBC numbering system. In addition, since Chapter 1 of the IEBC is not incorporated as part of the Virginia Rehabilitation Code VRC, any reference to a provision of Chapter 1 of the IEBC in the provisions of Chapters 2 - 15 16 of the IEBC is generally invalid. However, where the purpose of such a reference would clearly correspond to a provision of Chapter 1 established herein, then the reference may be construed to be a valid reference to such corresponding Chapter 1 provision.

E. Section 101.5 Use of terminology and notes. The term "this code," or "the code," where used in the provisions of Chapter 1, in Chapters 2 - 15 16 of the IEBC, or in the state amendments to the IEBC, means the Virginia Rehabilitation Code VRC, unless the context clearly indicates otherwise. The term "this code," or "the code," where used in a code or standard referenced in the IEBC, means that code or standard, unless the context clearly indicates otherwise. The term "USBC" where used in this code, means Part I of the Virginia Uniform Statewide Building Code, also known as the "Virginia Construction Code VCC," unless the context clearly indicates otherwise. In addition, where the phrase "of the International Building Code under which the building was constructed" is used in the IEBC, it shall be construed to mean the USBC or other code that was in effect when the building was built. Further, the use of notes in Chapter 1 is to provide information only and shall not be construed as changing the meaning of any code provision. Notes in the IEBC, in the codes and standards referenced in the IEBC and in the state amendments to the IEBC, may modify the content of a related provision and shall be considered to be a valid part of the provision, unless the context clearly indicates otherwise.

F. Section 101.6 Order of precedence. The provisions of this code shall be used as follows:

1. The provisions of Chapter 1 of this code supersede any conflicting provisions of Chapters 2 - 15 16 of the IEBC and that address the same subject matter and impose differing requirements.

2. The provisions of Chapter 1 of this code supersede any conflicting provisions of the codes and standards referenced in the IEBC that address the same subject matter and impose differing requirements. In addition, the

3. The state amendments to the IEBC supersede any conflicting provisions of Chapters 2 - 15 16 of the IEBC and that address the same subject matter and impose differing requirements.

4. The state amendments to the IEBC supersede any conflicting provisions of the codes and standards referenced in the IEBC that address the same subject matter and impose differing requirements. Further, the

5. The provisions of Chapters 2 - 15 16 of the IEBC supersede any conflicting provisions of the codes and standards referenced in the IEBC that address the same subject matter and impose differing requirements.

G. Section 101.7 Administrative provisions. The provisions of Chapter 1 establish administrative requirements, which include but are not limited to provisions relating to the scope and enforcement of the code. Any provisions of Chapters 2 - 15 16 of the IEBC or any provisions of the codes and standards referenced in the IEBC that address the same subject matter to a lesser or greater extent are deleted and replaced by the provisions of Chapter 1. Further, any administrative requirements contained in the state amendments to the IEBC shall be given the same precedence as the provisions of Chapter 1. Notwithstanding the above, where administrative requirements of Chapters 2 - 15 16 of the IEBC or of the codes and standards referenced in the IEBC are specifically identified as valid administrative requirements in Chapter 1 of this code or in the state amendments to the IEBC, then such requirements are not deleted and replaced.

Note: The purpose of this provision is to eliminate overlap, conflicts and duplication by providing a single standard for administrative, procedural and enforcement requirements of this code.

H. Section 101.8 Definitions. The definitions of terms used in this code are contained in Chapter 2 along with specific provisions addressing the use of definitions. Terms may be defined in other chapters or provisions of the code and such definitions are also valid.

13VAC5-63-410. Section 102 Purpose and scope.

A. Section 102.1 Purpose. In accordance with § 36-99.01 of the Code of Virginia, the General Assembly of Virginia has declared that (i) there is an urgent need to improve the housing conditions of low and moderate income individuals and families, many of whom live in substandard housing, particularly in the older cities of the Commonwealth; (ii) there are large numbers of older residential buildings in the Commonwealth, both occupied and vacant, which are in urgent need of rehabilitation and must be rehabilitated if the state's citizens are to be housed in decent, sound, and sanitary conditions; and (iii) the application of those building code requirements currently in force to housing rehabilitation has sometimes led to the imposition of costly and time-consuming requirements that result in a significant reduction in the amount of rehabilitation activity taking place.

The General Assembly further declares that (i) there is an urgent need to improve the existing condition of many of the Commonwealth's stock of commercial properties, particularly in older cities; (ii) there are large numbers of older commercial buildings in the Commonwealth, both occupied and vacant, that are in urgent need of rehabilitation and that must be rehabilitated if the citizens of the Commonwealth are to be provided with decent, sound and sanitary work spaces; and (iii) the application of the existing building code to such rehabilitation has sometimes led to the imposition of costly and time-consuming requirements that result in a significant reduction in the amount of rehabilitation activity taking place.

B. Section 102.2 Scope. In accordance with Section 103.6 of the USBC, this code shall be an acceptable alternative to compliance with the Virginia Construction Code for the rehabilitation of existing buildings and structures. The provisions of this code shall control the rehabilitation, reconstruction, alteration, repair, and change of occupancy of existing buildings and structures in occupancies other than Group R-5 and shall be permitted to be used as an alternative to compliance with the VCC for additions to buildings in any occupancy classification and for reconstruction, alteration or repair in Group R-5 occupancies.

Exception: The use of this code shall not be permitted for change of occupancy involving Group I-2 or I-3.

13VAC5-63-420. Section 103 Application of code.

A. Section 103.1 General. The provisions of this code shall control the rehabilitation, alteration, repair, addition and change of occupancy of existing buildings and structures when this code is chosen as an alternative to compliance with the Virginia Construction Code. All administrative provisions of the Virginia Construction Code VCC, including but not limited to, requirements for permits, inspections and approvals by the local building department, provisions for appeals from decisions of the local building department and the issuance of modifications, are applicable to the use of this code, except where this code sets out differing requirements. Where there is a conflict between a general requirement and a specific requirement in the IEBC, the specific requirement shall govern.

Exception: the use of this code shall not be permitted for change of occupancy involving Group I-2 or Group I-3.

B. Section 103.1.1 Use of performance code. Compliance with the provisions of a nationally recognized performance code when approved as a modification shall be considered to constitute compliance with this code. All documents submitted as part of such consideration shall be retained in the permanent records of the local building department.

C. Section 103.1.2 Preliminary meeting. When requested by a prospective permit applicant or when determined necessary by the code official, the code official shall meet with the prospective permit applicant prior to the application for a permit to discuss plans for the proposed work or change of occupancy in order to establish the specific applicability of the provisions of this code.

D. Section 103.2 Change of occupancy. No change of occupancy shall be made in any structure when the current USBC requires a greater degree of accessibility, structural strength, fire protection, means of egress, ventilation, or sanitation. When such a greater degree is required, the owner or the owner's agent shall make written application to the local building department for a new certificate of occupancy and shall obtain the new certificate of occupancy prior to the new use of the structure.

When impractical to achieve compliance with this code for the new occupancy classification, the building official shall consider modifications upon application and as provided for in Section 106.3 of the VCC.

E. Section 103.3 Retrofit requirements. In accordance with Section 103.7 of the VCC, the local building department shall enforce the provisions of Section 1701 that require certain existing buildings to be retrofitted with fire protection systems and other safety equipment. Retroactive fire protection system requirements contained in the IFC shall not be applicable unless required for compliance with the provisions of Section 1701.

F. Section 103.4 Nonrequired equipment. The following criteria for nonrequired equipment is in accordance with § 36-103 of the Code of Virginia. Building owners may elect to install partial or full fire alarms or other safety equipment that was not required by the edition of the VCC in effect at the time a building was constructed without meeting current requirements of the code, provided the installation does not create a hazardous condition. Permits for installation shall be obtained in accordance with the VCC. In addition, as a requirement of this code, when such nonrequired equipment is to be installed, the building official shall notify the appropriate fire official or fire chief.

G. Section 103.4.1 Reduction in function or discontinuance of nonrequired fire protection systems. When a nonrequired fire protection system is to be reduced in function or discontinued, it shall be done in such a manner so as not to create a false sense of protection. Generally, in such cases, any features visible from interior areas shall be removed, such as sprinkler heads, smoke detectors, or alarm panels or devices, but any wiring or piping hidden within the construction of the building may remain. Approval of the proposed method of reduction or discontinuance shall be obtained from the building official.

H. Section 103.5 Equipment changes. Upon the replacement or new installation of any fuel-burning appliances or equipment in existing buildings, an inspection or inspections shall be conducted to ensure that the connected vent or chimney systems comply with the following:

1. Vent or chimney systems are sized in accordance with either the IRC, the IMC, or the IFGC, depending on which is applicable based on the fuel source and the occupancy classification of the structure.

2. Vent or chimney systems are clean, free of any obstruction or blockages, defects, or deterioration, and are in operable condition.

Where not inspected by the local building department, persons performing such changes or installations shall certify to the building official that the requirements of Items 1 and 2 of this section are met.

I. Section 103.6 Requirements relating to maintenance. Any requirements of the IEBC requiring the maintenance of existing buildings or structures are invalid.

Note: Requirements for the maintenance of existing buildings and structures and for unsafe conditions are contained in Part III of the Virginia Uniform Statewide Building Code, also known as the "Virginia Maintenance Code VMC."

E. J. Section 103.3 103.7 Use of Appendix A. Appendix A of the IEBC provides guidelines for the seismic retrofit of existing buildings. The use of this appendix is not mandatory but shall be permitted to be utilized at the option of an owner, the owner's agent or the RDP involved in a rehabilitation project. However, in no case shall the use of Appendix A be construed to authorize the lowering of existing levels of health or safety in buildings or structures being rehabilitated.

F. K. Section 103.4 103.8 Use of Appendix B. Appendix B of the IEBC provides supplementary accessibility requirements for existing buildings and facilities. All applicable requirements of Appendix B shall be met in buildings and structures being rehabilitated.

G. L. Section 103.5 Use of Resource A. Resource A of the IEBC provides guidelines for the evaluation of fire resistance ratings of archaic materials and may be used in conjunction with rehabilitation projects.
