ORDINANCE AMENDING VARIOUS CHAPTERS AND SECTIONS OF TITLE 15 OF THE STOCKTON MUNICIPAL CODE BY INCORPORATING THE 2025 EDITION OF CALIFORNIA CODE OF REGULATIONS, TITLE 24, INCLUDING APPLICABLE APPENDICES (CALIFORNIA MODEL BUILDING AND FIRE CODE).

BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF STOCKTON, AS FOLLOWS:

SECTION I. FINDINGS AND INTENT

The City Council of the City of Stockton finds that the building standards, rules, and regulations established in Title 24 of the 2025 Edition of the California Code of Regulations, including applicable appendices, shall be adopted and incorporated by reference into the Stockton Municipal Code, Title 15, Chapters 15.04, 15.08, 15.10, 15.12, 15.16, 15.20, 15.36, 15.40, 15.64,

15.72, 15.82, and 15.86.

In connection with the local amendments to the 2025 Edition of the California Code of Regulations, Title 24, including applicable appendices set forth below, and pursuant to California Health and Safety Code sections 17958, 1795 8.5, 17958.7, and 18941.5, the City Council finds that:

A. The location of Stockton within an area of expansive clay soils, the proximity of the City to the San Joaquin River Delta system, and the extreme hot summer temperatures with very low humidity, seasonal winds of high velocities, extreme seasonal visibility red uction due to thick fog, and the current pattern of development in relation to the location of emergency services require the following amendments, additions, and deletions to the standards, rules, and regulations to mitigate unique local climatic, geological, or topographical conditions.

B. Under this adopting ordinance, specific amendments are established that are more restrictive than those adopted by the State of California under the State Buildings Standards Code, Title 24 of the California Code of Regulations, Title 24.

C. Express Finding Number 1: Climatic

Climate has the greatest impact on fire behavior and other natural disasters. Stockton has significant variations in weather patterns. Summers are arid and hot, winters are cool to freezing, fall and spring can bring any combination of weather patterns together. These variations in weather patterns can result in weather events such as above average rainfall and rapid melting of the Sierra snowpack that causes flooding in the low -lying areas of San Joaquin County.

Additionally, the proximity of the City to the San Joaquin River Delta system leaves the City prone to flooding.

Average yearly rainfall in Stockton is approximately 17 inches , however the City occasionally has storm events where rainfall rates can be as much as 2 inches per hour. The rainfall normally occurs from October to April. Low-level dense fog (Tule fog) is present throughout winter months, which brings visibility to nearly zero feet. The fog can also cause freezing and slick Attachment A
2 roadways contributing to vehicular accidents.

During summer months there is generally no measurable precipitation. Temperatures during the hot and dry summer range from 70 to 115 degrees Fahrenheit. The relative humidity in summer months is low. The City contains many acres of undeveloped grass lands and vacant infill lots with overgrown vegetation, which, in conjunction with occasional high velocity winds, creates a hazardous situation for fire conflagration. High velocity winds also contribute to hazardous fire behavior in urban fire events.

The following building standards in the Stockton Municipal Code are added or amend the 2025 Edition of the California Code of Regulations, Title 24, based upon this express finding:

Stockton Municipal Code Section s 15.08.070 fire protection systems, 15.08.090 address identification, 15.10.040 amendments to the California Residential Code, 15.12.010 through

15.12.110 amendments to the California Fire Code, 15.16.020 amendments to the California Plumbing Code, and 15.36.030 through 15.36.050 additions to the California Electrical Code.

D. Express Finding Number 2: Geological

Stockton is subject to seismic events as the City is located is Seismic Design Category D, which relates to a high risk of earthquakes. The high seismic zone is based on proximity to known fault lines and soil type. Significant portions within Stockton are known to have poor soil conditions, mainly expansive clay soils. Additionally, the low elevations of the City are subject to a high water table. Structural designs based on minimum model codes, not accounting for these soil conditions, may result in differential settlement and moisture penetration within buildings.

The following building standards in the Stockton Municipal Code are added or amend the 2025 Edition of the California Code of Regulations, Title 24, based upon this express finding:

Stockton Municipal Code Sections 15.08.040 local soil conditions and 15.08.080 plain concrete.

E. Express Finding Number 3: Topographical

Stockton is impacted by several topographical features, including major rivers, creeks and streams, lakes, sloughs, natural parkways, bridges and overpasses, the Port of Stockton, freeways, railroad lines , and drainage canals. Traffic congestion through and around these features delays emergency response. In the event of an emergency at a main thoroughfare , portions of the city could be isolated due to these topographical features , sufficiently delaying emergency response increasing the risk of injury or damage.

Preservation of wetland areas, natural parkways, riparian corridors along rivers and streams, open space, and endangered species habitat all contribute to access problems as well as exemption from vegetation abatement programs. These situations, though environmentally important, increase the demands on the fire service due to extreme fire hazard created by fuel loading and limited access.

The following building standards in the Stockton Municipal Code are added or amend the Attachment A
3 2025 Edition of the California Code of Regulations, Title 24, based upon this express finding:

Stockton Municipal Code Sections 15.08.070 fire protection systems, 15.08.090 address identification, 15.10.040 amendments to the California Residential Code, 15.12.010 through

15.12.110 amendments to the California Fire Code, and 15.36.030 through 15.36.050 additions to the California Electrical Code.

The City Council also finds those existing provisions of Title 15 of the Stockton Municipal Code which are not hereby adopted, amended, or repealed are amendments, additions, or deletions to the standards, rules, and regulations of the California Model Codes which are necessary to mitigate the above -noted unique local conditions and continue to impose substantially the same requirements of the 2025 Edition of the California Code of Regulations, Title 24, including applicable appendices.

The City Council further finds that the local amendments to the 2025 Edition of the California Code of Regulations, Title 24, including applicable appendices , related to residential units set forth below are substantially equivalent to changes or modifications that were previously filed by the city and in effect as of January 1, 2023, pursuant to California Health and Safety Code section 17958.5(c)(1).
