ADOPT THE LATEST EDITIONS OF THE UNIFORM CODES
AND MAKE EDITORIAL AND MINOR CHANGES AND DELETIONS
TO THE MUNICIPAL CODE AND ADOPTING FINDINGS
OF FACTS TO SUPPORT THE IMPOSITION OF
REQUIREMENTS WHICH ARE GREATER THAN
THE REQUIREMENTS ESTABLISHED BY OR PURSUANT
TO THE STATE BUILDING CODE
WHEREAS, it is the desire and intent of the City Council of the
City of San Luis Obispo to provide citizens with the greatest
degree of fire, life and structural safety in buildings in the most
cost effective manner by adopting that body of regulations
generally referred to as the Uniform Construction Codes with
amendments specific to the City of San Luis Obispo; and
WHEREAS, the California Health and Safety Code, Chapter 4, Part
1.5, Division XIII, Section 17958, Section 17958.5 and Section
17958.7 requires the City Council, before making any modifications
or changes to the State Building Standards Code pursuant to Health
and Safety Code Section 17958.5, to make an express finding that
each such modification or change is needed; and,
WHEREAS, the California Health and Safety Code Section 17958.5
requires that such changes must be determined to be reasonably
necessary because of local climatic, geographical, or topographical
conditions; and,
WHEREAS, such findings must be made available as a public record
and a copy thereof with each such modification or change shall be
filed with the State of California Department of Housing and
Community Development;
WHEREAS, Sections 2623, 2905, 2907 and 4506 and Table 29 -A of the
Uniform Building Code have had previous findings made for their
modification and said findings as contained in Resolution No. 637
(1987 Series) have been transmitted to the State of California
Department of Community Development and have been accepted; and,
NOW THEREFORE BE IT ORDAINED that the Council of the City of San
Luis Obispo affirms the findings justifying the previous changes
and modifications as contained in Ordinance No. 1105 (1987
Series) and Ordinance 1033 (1985 Series);
BE IT FURTHER ORDAINED that the City Council hereby determines
that Sections 502, 2623, 2905, 2907, 3201, 3802 and 4506 and
Table 29 -A of the 1988 Uniform Building Code, and Section 317 of
the 1988 Uniform Plumbing Code and Article 230 -70 of the 1987
0 1169
2
National Electrical Code are required to be modified due to the
findings contained herein to greater requirements than those set
forth in the California State Building Standards Code and that
Sections 1709 and 3305 of the 1988 Uniform Building Code be
modified to lesser requirements than those set forth in the
California State Building Standards Code;
BE IT FURTHER ORDAINED by the City Council that each of the
changes or modifications to measures referred to therein are
reasonably necessary because of local climatic, geographical, or
topographical conditions in the area encompassed by the
boundaries of the City of San Luis Obispo, and the City Council
further finds that the following findings support the local
necessity for the changes or modifications:
FINDING 1
That the City of San Luis Obispo is situated at the base of a
watershed of the Santa Lucia Mountains and that flooding of San
Luis, Chorro, Stenner, Old Garden, and Brizzolara Creeks results
in conditions rendering fire department vehicular traffic unduly
burdensome or impossible as witnessed in major floods that
occurred in 1952, 1961, 1969, 1973, 1978, and 1982. Furthermore,
flood conditions described above create the potential for
overcoming the ability of the fire department to aid or assist in
fire control, evacuations, rescues and other emergency task
demands inherent in such situations. The resulting overburdening
of fire department personnel may cause a substantial or total
lack of protection against fire for the buildings and structures
located in the City of San Luis Obispo. The afore - described
conditions support the imposition of fire protection requirements
greater than those set forth in the State Building Standards Code
and, in particular, support the imposition of greater
requirements than set forth in Sections 502, 1701, 3201, 3802 and
4506 of the 1988 Uniform Building Code, and Article 230 -70 of the
1987 National Electrical Code.
FINDING 2
That the City of San Luis Obispo is situated near three major
faults each capable of generating earthquakes with a magnitude of
7.5. These are the San Andreas to the east of the City, the
Nacimiento - Rinconada that crosses Hwy 101 north of the City then
parallels the City to the east, and the Hosgri to the West.
Other faults of importance are the Huasna and West Huasna to the
Southeast of the City, the San Simeon to the Northwest, and the
Edna and Edna Extended faults which enter the southern areas of
the City. In as much as these faults are included as major
California earthquake faults, which are subject to becoming
active at any time, the City of San Luis Obispo is particularly
vulnerable to devastation should such an earthquake occur. The
potential effects include isolating the City of San Luis Obispo
from the North and South due to the potential for collapsing of
freeway overpasses or a slide on both the Cuesta and Ontario
Grades and the potential for horizontal or vertical movement of
3
the Edna fault rendering surface travel across the southern
extremities of the city unduly burdensome or impossible.
Additional potential situations inherent in such an occurrence
include loss of the City's two main water sources (the Salinas
and Whale Rock reservoirs), broken natural -gas mains causing
structure and other fires, leakage of hazardous materials, the
need for rescues from collapsed structures, and the rendering of
first aid and other medical attention to large numbers of people.
The protection of human life and the preservation of property in
the event of such an occurrence support the imposition of fire
protection requirements greater than those set forth in the
California State Building Standards Code and in particular
support the imposition of greater requirements than set forth in
Sections 502, 1701, 3201, 3802 and 4506 of the 1988 Uniform
Building Code, and Article 230 -70 of the 1987 National Electrical
Code.
FINDING 3
That the central commercial area in the City of San Luis Obispo
consists of mixed conditions which create the potential for
possible conflagration, including congested streets during the
business day, numerous older buildings without adequate internal
fire - resistivity, and contemporary low -rise buildings.
Significant spread of fire in said area will actually exceed the
fire suppression capabilities. of regional firefighting personnel.
The continued development of the San Luis Obispo commercial area
and the current and potential development of high -rise buildings
pose a substantial threat of fire to human life, public safety,
and the preservation of property and support the imposition of
fire protection requirements greater than those set forth in the
California State Building Standards Code, and in particular,
support the imposition of greater requirements than set forth in
Sections 502, 3201, 3802 and 4506 of the 1988 Uniform Building
Code, and Article 230 -70 of the 1987 National Electrical Code.
FINDING 4
That the City of San Luis Obispo is bisected by a major freeway
(Hwy 101), traversing in the north /south direction and a major
highway (Hwy 1) traversing in an east /west direction. The City
is also transected by a mainline railroad which traverses in the
north /south direction. It is a frequent occurrence for the
aforementioned highways and railway to support the transportation
of hazardous materials. The potential for release or threatened
release of a hazardous material along one of these routes is
highly probable given the volume transported daily. Incidents of
this nature will normally require all available emergency
response personnel to prevent injury and loss of life, and to
prevent as far as practicable, property losses. Emergency
personnel responding to said incidents may be unduly impeded and
delayed in accomplishing an emergency response as a result of
this situation, with the potential result of undue and
unnecessary risk to the protection of life and public safety,
particularly in those buildings or structures without the
4
protection of automatic fire sprinklers. The afore - described
problems support the imposition of fire protection requirements
greater than those set forth in the State Building Standards
Code, and in particular support the imposition of greater
requirements than set forth in Sections 502, 1701, 3201, 3802 and
4506 of the 1988 Uniform Building Code, and Article 230 -70 of the
1987 National Electrical Code.
FINDING 5
That seasonal climatic conditions during the late summer and fall
create numerous serious difficulties in the control and
protection against fire situations in the City of San Luis
Obispo. The hot, dry weather in combination with Santa Ana winds
frequently results in wildland fires in the brush - covered slopes
on the Santa Lucia Mountains, San Luis Mountain, and the Irish
Hills areas of the City of San Luis Obispo. The aforementioned
areas completely surround the City. When a fire occurs in said
areas, such as occurred in 1985 when the Los Pilitas fire burned
six days and entered the City and damaged many structures, the
entirety of local fire department personnel is required to
control, monitor, fight and protect against such fire situations
in an effort to protect life and preserve property and watershed
land. The same climatic conditions may result in the concurrent
occurrence of one or more fires in the more populated areas of
the City without adequate fire department personnel to protect
against and control such a situation. Therefore, the
above - described findings support the imposition of fire -
protection requirements greater than those set forth in the State
Building Standards Code, and in particular support the imposition
of greater requirements than set forth in Sections 502, 1701,
3201, 3802 and 4506 of the 1988 Uniform Building Code and Article
230 -70 of the 1987 National Electrical Code.
FINDING 6
That for the most part, the soils in the City of San Luis Obispo
are medium to highly expansive in nature, and such soils may
cause damage to foundations, structures and underground utilities
if not properly mitigated through known construction techniques.
Furthermore, a significant part of the City lies on hills and
rolling topography which are subject to earth slides and
movements and present problems to developments constructed in
such areas due to surface water drainage and disposal. The
above - described conditions support the imposition of requirements
greater than those set forth in the State Building Standards Code
and, in particular, support the imposition of greater
requirements than those set forth in Sections 502, 2623, 2905,
2907 and Table 29 -A of the 1988 Uniform Building Code and Section
317 of the Uniform Plumbing Code.
FINDING 7
That the more - restrictive modifications requiring automatic fire -
sprinkler systems in buildings evidenced by the afore - described
findings allow a trade -off for, and reduction of, other less
9
effective fire - resistive components of a building support the
acceptance of requirements lesser than those set forth in State
Building Standards Code and, in particular, support the
imposition of lesser requirements than those set forth in
Sections 1709 and 3305 of the 1988 Uniform Building Code.
BE IT ORDAINED by the City Council that the provisions of the
State Building Standards Code are hereby modified, changed and
amended, as provided for in this ordinance, based upon the
foregoing findings and that said Council takes said action
because of the public interest in protecting life and preserving
public safety and property.
BE IT FURTHER ORDAINED that the City Clerk be and hereby is
authorized and directed to transmit a certified copy of this
ordinance, adopting and modifying the Uniform Building Code,
Uniform Plumbing Code, Uniform Mechanical Code and National
Electrical Code to the State of California Department of Housing
and Community. Development.
NOW, THEREFORE, BE IT ORDAINED by the Council of the City of San
Luis Obispo as follows:

requiring reinspection fees the first time a job
is rejected for failure to comply with the
requirements of the technical codes, but as
controlling the practice of calling for
inspections before the job is ready for such
inspection or reinspection.
Reinspection fees may be assessed when the permit
card is not properly posted on the work site, the
approved plans are not readily available to the
inspector, for failure to provide access on the
date for which inspection is requested, or for
deviating from plans requiring the approval of the
