ORDINANCE NO. 1134
AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF NORCO,
CALIFORNIA, ADOPTING THE 2025 CALIFORNIA BUILDING
STANDARD CODES, TO AMEND NORCO MUNICIPAL CODE TITLE 15
“BUILDINGS AND CONSTRUCTION”. CODE AMENDMENT 2025-05
WHEREAS, THE CITY OF NORCO initiated Code Amendment No. 2025-05, amending Title 15 of the Norco Municipal Code to adopt the 2025 California Building Codes as the Official Building Codes for the City of Norco; and WHEREAS, at the regular meeting on September 17, 2025, the Norco City Council conducted a public hearing and received and considered oral and written testimony concerning the proposed code change; and
WHEREAS, the California Health and Safety Code requires cities and counties to adopt building standards that are consistent with those contained in the California Code of Regulations Title 24; and
WHEREAS, State law allows local governments to amend California Model Codes, providing the amendments are more restrictive and are necessary in order to provide the highest level of life-safety standards and requires that local governments enforce these code editions.
NOW, THEREFORE, the City Council of the City of Norco, California, does hereby make the following FINDINGS:
A. California Health & Safety Code, Section 17958.5 and 18941.5 authorizes cities and counties to modify the California Building Standards Code by adopting more restrictive standards and modifications if such standards and modifications are accompanied by express findings that they are reasonably necessary because of local climatic, geological or topographical conditions.
B. The City Council of the City of Norco finds that these local climatic, geological or topographical conditions include, but are not limited to, the following:
1. The City is subject to relatively low amounts of precipitation, very low humidity levels and extremely high temperatures. These climatic conditions are conducive to the spread of drought conditions and fires. For example, during July, August and September, temperatures often exceed 100 degrees Fahrenheit. During the same months humidity is usually less than 40% and measurements of less than 10% are not uncommon. These recordings have been documented by the Riverside County Flood Control District and the National Climatic Data Center.
2. The City is subject to extremely strong winds, commonly referred to as "Santa Ana Winds," which can reach speeds of up to 102 miles per hour. In addition, the convergence of the marine shore air flow and the desert air flow create
Ordinance No. 1134 Code Amendment 2025-05 (2025 California Building Codes) Page 2
October 15, 2025
steady winds on a daily basis. Finally, the City is bordered on the south by steep, rugged, brush-covered mountains and parts of the City contain hilly terrain and mounds, which either contribute to or create gusty wind conditions by causing a natural funneling effect and increasing wind speeds over the City.
3. The City is also subject to moderately strong shaking and surface ruptures from seismic activity in the area. The geologic and seismic setting of the City is dominated by the Chino and Elsinore earthquake faults along the southwest portion of the City and a diversity of bedrock and alluvial soils that may significantly affect the intensity of earthquake shaking. The Elsinore fault is located a short distance southwest of the City, while the Chino fault, which is subparallel to the Elsinore fault, is located just inside the City's southwestern boundary. Of the two faults, the Chino fault has the greater potential for surface rupture leading to structural damage of structures in the City. Moreover, the thin alluvial soils found in parts of the City contribute to a moderately high potential for liquefaction in certain areas.
C. The aforementioned geologic and climatic conditions have also contributed to the loss or damage of 450 homes in the Bel Air Fire of 1961; 187 homes in the Chatsworth Fire of 1970; 50 homes in the Mandeville Canyon Fire of 1978; 262 homes in the Anaheim Fire of 1982; 71 homes in the Baldwin Hills Fire of 1985; 33 homes in the Porter Ranch Fire of 1988; 162 homes in the Santa Barbara Fire of 1990; hundreds of acres in the nearby Chino Hills State Park Fire of 1997; the Corona Triangle/Freeway Complex Fire November 15, 2008 burned 318 properties, burned 30,305 plus acres, destroyed 187 single/multiple family homes, damaged 127 homes, damaged or destroyed four commercial properties; 200 acres were burned in the Sierra Pass Fire on September 24, 2013; the Madre Fire which burned 268 acres on September 23, 2013; the Little Fire on August 29, 2013 which burned 97 acres; the Deluz Fire on October 5, 2013 which burned 2236 acres, threatened 300 residents and the Naval Hospital; the Forks Complex Fire October 1, 2013 burned 37,246 acres; the Rim Fire September 3, 2013 which burned 257,314 acres, destroyed 3 commercial buildings and 11 residences; the Thomas Fire on December 4, 2017 burned 281,893 acres, 1063 structures and caused 2 deaths; the Woolsey Fire in November 2018 destroyed 1643 structures and caused 3 deaths; the Palisades Fire in January 2025 destroyed 6,837 structures and caused 12 deaths; and the Eaton Fire in January 2025 destroyed 9418 structures and caused 19 deaths.
D. These fires, as well as the recent Whittier Earthquake of 1987, Northridge Earthquake of 1994, the Chino Hills Earthquake of 2008 and the recent 2019 Ridgecrest Earthquakes have resulted in the tragic loss of lives along with enormous property losses.
E. For practicality and cost reasons, many new structures are built of wood (Type V) construction. The potential for a conflagration exists due to the design and density of current structures.
Ordinance No. 1134 Code Amendment 2025-05 (2025 California Building Codes) Page 3
October 15, 2025
F. Electrical supply and telephone communication failures occur due to high winds as well as other reasons. Water supply pumps and early notification of a fire cannot always be counted on.
G. Based upon the recommendations of the Building Official, the City Council finds that the proposed amendments to the 2025 California Building Standards Code ("amendments") are more restrictive than the standards adopted by the California Building Standards Commission, would decrease the potential incidence of property damage, injury and death due to fires and earthquakes, and are reasonable and necessary to mitigate the aforementioned local climatic, geologic or topographical conditions.
SECTION 1. FINDINGS.
Title 15 (Buildings and Construction) is hereby amended to read as follows Existing Chapters and Sections in Title 15 not amended below shall remain effective:
Title 15
Buildings and Construction
