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 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 2012 2015
edition of the USBC due to the use of the 2012 2015 editions of
the model codes.
B. Section 101.2 Incorporation by reference. Chapters 2 - 35
of the 2012 2015 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 2012
2015 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 other International Codes and
standards including the following major codes:
2012 2015 International Plumbing Code (IPC)
2012 2015 International Mechanical Code (IMC)
2011 2014 NFPA 70
2012 2015 International Fuel Gas Code (IFGC)
2012 2015 International Energy Conservation Code
(IECC)
2012 2015 International Residential Code (IRC)
Note 2: The IRC is applicable to the construction of detached
one-family 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 provisions
of this code shall be used as follows:
1. 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.
2. 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.
3. 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.
4. 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
provisions of Chapters 2 - 35 of the IBC that address the same subject matter
and impose differing requirements.
2. The provisions of Chapter 1 of this code supersede any
provisions of the codes and standards referenced in the IBC that address the
same subject matter and impose differing requirements.
3. The state amendments to the IBC supersede any provisions of
Chapters 2 - 35 of the IBC that address the same subject matter and impose
differing requirements.
4. The state amendments to the IBC supersede any provisions of
the codes and standards referenced in the IBC that address the same subject
matter and impose differing requirements.
5. The provisions of Chapters 2 - 35 of the IBC supersede any
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.

systems, and (iii) solid waste facilities. Nor shall state agencies be
prohibited from requiring, pursuant to other state law, that buildings and
equipment be maintained in accordance with provisions of this code. In
addition, as established by this code, the building official may refuse to
issue a permit until the applicant has supplied certificates of functional
design approval from the appropriate state agency or agencies. For purposes of
coordination, the locality may require reports to the building official by
other departments or agencies indicating compliance with their regulations
applicable to the functional design of a building or structure as a condition
for issuance of a building permit or certificate of occupancy. Such reports
shall be based upon review of the plans or inspection of the project as
determined by the locality. All enforcement of these conditions shall not be
the responsibility of the building official, but rather the agency imposing the
condition.
Note: Identified state agencies with functional design
approval are listed in the "Related Laws Package," which is available
from DHCD.
M. N. Section 103.11 Amusement devices and
inspections. In accordance with § 36-98.3 of the Code of Virginia, to the

the exception that §§ 2.2-1159 through 2.2-1161 of the Code of Virginia
shall provide the standards for ready access to and use of state-owned
buildings by the physically handicapped.
Any state-owned building or structure or building built on
state-owned property 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 subsection D E of § 23-38.109
23.1-1016 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 subsection B A of § 23-38.88 23.1-1002
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. On an annual basis, the Department of Transportation shall provide a
report on the maintenance and operability of installed fire protection and
detection systems in roadway tunnels and bridges to the State Fire Marshal.

13VAC5-63-40. Section 104 Enforcement, generally.
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.
However, upon a finding by the local building department,
following a complaint by a tenant of a residential 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 VMC exists that is an immediate and imminent threat to the
health or safety of the owner, tenant, or occupants of any building or
structure, or the owner, occupant, or tenant of any nearby building or
structure, and the owner, occupant, or tenant of the 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 building or structure, the local
building official or his agent may present sworn testimony to make an
affidavit under oath before 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 building or structure for the purpose of
determining whether violations of the VMC exist. After issuing a warrant
under this section, the magistrate or judge shall file the affidavit in the
manner prescribed by § 19.2-54 of the Code of Virginia. After
executing the warrant, the local building official or his agents shall return
the warrant to the clerk of the circuit court of the city or county wherein the
inspection was made. The local building official or his agent shall make a
reasonable effort to obtain consent from the owner, occupant, or tenant of the
subject 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 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.
13VAC5-63-50. Section 105 Local building department.
A. Section 105.1 Appointment of building official. Every
local building department shall have a building official as the executive
official in charge of the department. The building official shall be appointed
in a manner selected by the local governing body. After permanent appointment,
the building official shall not be removed from office except for cause after
having been afforded a full opportunity to be heard on specific and relevant
charges by and before the appointing authority. DHCD shall be notified by the
appointing authority within 30 days of the appointment or release of a permanent
or acting building official.
Note: Building officials are subject to sanctions in
accordance with the VCS.
B. Section 105.1.1 Qualifications of building official. The

For SI: 1 ft = 304.8 mm. a. Interpolation shall be permitted; extrapolation shall be
prohibited. b. For Exposure Category C, multiply the required length of
bracing by a factor of 1.20 for a one-story building, 1.30 for a two-story
building, and 1.40 for a three-story building. c. For wall height adjustments multiply the required length
of bracing by the following factors: 0.90 for 8 feet (2438 mm), 0.95 for 9
feet (2743 mm), 1.0 for 10 feet (3048 mm), 1.05 for 11 feet (3353 mm), and
1.10 for 12 feet (3658 mm). d. Where braced wall panels supporting stories above have
been sheathed in wood structural panels with edge fasteners spaced at 4 inches
(102 mm) on center, multiply the required length of bracing by 0.83. e. A floor level, habitable or otherwise, contained wholly
within the roof rafters or trusses shall not be considered a floor level for
purposes of determining the required length of bracing. f. A rectangle side with differing number of floor levels
above shall use the greatest number when determining the required length of
bracing. |
R602.12.4.1 Braced wall panel assignment to rectangle sides.
Braced wall panels shall be assigned to the applicable rectangle side and
contribute to its required length of bracing. Panels shall be assigned as
specified below and as shown in Figure R602.12.4.1.
1. Exterior braced wall panels shall be assigned to the
parallel rectangle side on which they are located or in which they face.
2. Interior braced wall panels shall be assigned to the
parallel rectangle side on which they are located or in which they face up to 4
feet (1220 mm) away. Interior braced wall panels more than 4 feet (1220 mm)
away from a parallel rectangle side shall not contribute.
3. The projections of angled braced wall panels shall be
assigned to the adjacent rectangle sides.
R602.12.4.2 Contributing length. The cumulative contributing
length of braced wall panels assigned to a rectangle side shall be greater than
or equal to the required length of bracing as determined in Section R602.12.4.
The contributing length of a braced wall panel shall be as specified below.
When applying contributing length to angled braced wall panels, apply the
requirements below to each projection:
1. Exterior braced wall panels shall contribute their actual
length.
2. Interior braced wall panels shall contribute one-half of
their actual length.
3. The contributing length of Methods ABW, PFH, PFG, and CS-PF
shall be in accordance with Table R602.10.5.
R602.12.4.3 Common sides with skewed rectangles. Braced wall
panels located on a common wall where skewed rectangles intersect, as shown in
Figure R602.12.4.3, shall be permitted to be assigned to the parallel rectangle
side, and their projections shall be permitted to be assigned to the adjacent
skewed rectangle sides.
R602.12.5 Cripple walls and framed walls of walk-out
basements. For rectangle sides with cripple walls having a maximum height of 48
inches (1220 mm), the required length of bracing shall be as determined in
Section R602.12.4. For rectangle sides with cripple walls having a height greater
than 48 inches (1220 mm) at any location or framed walls of a walk-out
basement, the required length of bracing shall be determined using Table
R602.12.4. Braced wall panels within cripple walls and walls of walk-out
basements shall comply with Item 4 of Section R602.12.2.
R602.12.6 Distribution of braced wall panels. Braced wall
panels shall be distributed in accordance with the following requirements as
shown in Figure R602.12.6.
1. The edge of a braced wall panel shall be no more than 12
feet (3658 mm) from any building corner or rectangle corner.
2. The distance between adjacent edges of braced wall panels
shall be no more than 20 feet (6096 mm).
3. Segments of exterior walls greater than 8 feet (2438 mm) in
length shall have a minimum of one braced wall panel.
4. Segments of exterior wall 8 feet (2438 mm) or less in
length shall be permitted to have no braced wall panels.
R602.12.6.1 Panels adjacent to balloon framed walls. Braced
wall panels shall be placed on each side of each story adjacent to balloon
framed walls designed in accordance with Section R602.3 with a maximum height
of two stories.
R602.12.7 Braced wall panel connection. Braced wall panels
shall be connected to other structural elements in accordance with Section
R602.10.8.
R602.12.8 Braced wall panel support. Braced wall panels shall
be supported in accordance with Section R602.10.9.
