Preface THE UNIFORM BUILDING CODE is dedicated to the development
of
better building construction and greater safety to the public by
uniformity in building laws. The code is founded on broad-based
performance principles that make possible the usc of new materials
and new construction systems.
THE UNIFORM BUILDING CODE was first enacted by the International
Conference of Building Officials at the Sixth Annual Business
Meeting held in Phoenix, Arizona, October 18-21, 1927. Revised
editions of this code have been published since that time at
approximate three-year intervals. New editions incorporate changes
approved since the last edition.
THE UNIFORM BUILDING CODE is designed to be compatible with related
publications listed on the following pages to provide a complete
set of documents for regulatory use.
Anyone may propose amendments to this code. For more information,
write to the International Conference of Building Officials at the
address on the copyright page.
Changes to the code are processed each year and published in
supplements in a form permitting ready adoption by local
communities. These changes are care fully reviewed in public
hearings by professional experts in the field of building
construction and fire and life safety.
Solid vertical lines in the margins indicate a change from the
requirements of the 1982 edition except where the entire chapter
was revised, a new chapter was added or the change was minor. Where
an entire chapter is changed or new chapter was added, a notation
appears at the beginning of that chapter. Vertical lines in the
margins that are interrupted by the letter "F" indicate that the
provision is maintained under the code change procedures of the
Western Fire Chiefs Associa tion. Deletion indicators ( .. ) are
provided in the margin where a paragraph or item listing has been
deleted if the deletion resulted in a change of requirements.
An analysis of changes between editions is published in pamphlet
form by the Conference.

EFFECTIVE USE OF THE UNIFORM BUILDING CODE
The following procedure may be helpful in using the Uniform
Building Code:
I. Classify the building: A. OCCUPANCY GROUP: Determine the
occupancy group which the
use of the building most nearly resembles. See the '0 I sections of
Chapters 5 through 12. Sec Section 503 for buildings with mixed
occupancies.
B. TYPE OF CONSTRUCTION: Determine the type of construction of the
building by the building materials used and the fire resistance of
the parts of the building. See Chapters 17 through 22.
C. LOCATION ON PROPERTY: Determine the location of the building on
the site and clearances to property lines and other buildings from
the plot plan. Sec Table No. 5-A and '03 sections of Chapters 18
through 22 for exterior wall and wall opening requirements based on
proximity to property lines. Sec Section 504 for buildings located
on the same site.
D. FLOOR AREA: Compute the floor area of the building. Sec Table
No. 5-C for basic allowable floor area based on occupancy group and
type of construction. See Section 506 for allowable increases based
on location on property and installation of an approved automatic
fire-sprinkler system. See Section 505 (b) for allowable floor area
of multistory buildings.
E. HEIGHT AND NUMBER OF STORIES: Compute the height of the
building, Section 409, from grade, Section 408, and for the number
of stories, Section 420. See Table No. 5-D for the allowable height
and number of stories based on occupancy group and type of
construction. Sec Section 507 for allowable story increase based on
the installation of an approved automatic fire-sprinkler
system.
F. OCCUPANT LOAD: Compute the occupant load of the building. See
Section 3302 and Table No. 33-A.
2. Verify compliance of the building with detailed occupancy
requirements. See Chapters 6 through 12.
3. Verify compliance of the building with detailed type of
construction re quirements. See Chapters 17 through 22.
4. Verify compliance of the building with exit requirements. See
Chapter 33.
5. Verify compliance of the building with detailed code
regulations. See Chapters 29 through 43, Chapters 47 through 54,
and Appendix.
6. Verify compliance of building with engineering regulations and
require ments for materials of construction. See Chapters 23
through 29.
The following is a sample form for adoption ofthe Uniform Building
Code and Uniform Building Code Standards.

the existing building or structure to comply with all the
requirements of this code. provided the addition. alteration or
repair conforms to that required for a new building or structure.
Additions or alterations shall not be made to an existing building
or structure which will cause the existing building or structure to
be in violation of any of the provisions of this code nor shall
such additions or alterations cause the existing building or
structure to become unsafe. An unsafe condition shall be deemed to
have been created if an addition or alteration will cause the
existing building or
104 UNIFORM BUILDING CODE
structure to become structurally unsafe or overloaded; will not
provide adequate egress in compliance with the provisions of this
code or will obstruct existing exits; will create a fire hazard;
will reduce required fire resistance or will other wise create
conditions dangerous to human life. Any building so altered, which
involves a change in use or occupancy, shall not exceed the height,
number of stories and area permitted for new buildings. Any
building plus new additions shall not exceed the height, number of
stories and area specified for new build ings. Additions or
alterations shall not be made to an existing building or structure
when such existing building or structure is not in full compliance
with the provisions of this code except when such addition or
alteration will result in the existing building or structure being
no more hazardous based on life safety, fire safety and sanitation,
than before such additions or alterations arc undertaken. [See also
Section 911 (c) for Group H, Division 6 Occupancies.]
Alterations or repairs to an existing building or structure which
are nonstruc tural and do not adversely affect any structural
member or any part of the building or structure having required
fire resistance may be made with the same materials of which the
building or structure is constructed. The installation or
replacement of glass shall be as required for new
installations.
(c) Existing Installations. Buildings in existence at the time of
the adoption of this code may have their existing use or occupancy
continued, if such use or occupancy was legal at the time of the
adoption of this code, provided such continued usc is not dangerous
to life.
Any change in the use or occupancy of any existing building or
structure shall comply with the provisions of Sections 307 and 502
of this code.
For existing buildings, see Appendix Chapter I.
(d) Maintenance. All buildings and structures, both existing and
new. and all parts thereof, shall be maintained in a safe and

determine compliance with this subsection, the building official
may cause any structure to be reinspected.
(c) Moved Buildings and Temporary Buildings. Buildings or
structures moved into or within the jurisdiction shall comply with
the provisions of this code for new buildings or structures.
Temporary structures such as reviewing stands and other
miscellaneous struc tures, sheds, canopies or fences used for the
protection ofthe public around and in conjunction with construction
work may be erected by special permit from the building official
for a limited period of time. Such buildings or structures need not
comply with the type of construction or fire-resistive time periods
required by this code. Temporary buildings or structures shall be
completely removed upon the expiration of the time limit stated in
the permit.
(f) Historic Buildings. Repairs, alterations and additions
necessary for the preservation, restoration. rehabilitation or
continued use of a building or structure may be made without
conformance to all the requirements of this code when authorized by
