CALIFORNIA BUILDING CODE

Section 16.02.010. Title.

This chapter shall be cited as the California Building Code of the city and any reference in the city municipal code or any chapter thereof to the California Building Code applies to this chapter. (Ord. 2019-12 § 2016-12 § 2, 2016)

Section 16.02.020. Code adoption.

The city of American Canyon does hereby adopt all those certain documents marked and designated, as "California Building Code, 2022 Edition," published and copyrighted by the International Code Council. The documents identified in this section are adopted in their entirety excepting additions, revisions and omissions listed in Sections 16.02.030 through 16.02.260 of this chapter. A copy of the adopted California Building Code shall be kept on file in the office of the building official for use and examination by members of the public. (Ord. 2019-12 § 2016-12 § 2, 2016)

Section 16.02.030. Appendices.

(Ord. 2019-12 § 2016-12 § 2, 2016)

Section 16.02.040. Findings and determination.

As permitted in Health and Safety Code Section 17958.7, the city of American Canyon finds and determines the local amendments to the 2022 California Building Code are either administrative in nature or reasonably necessary to protect the health, safety and general welfare of the public due to local climatic, geological or topographical conditions. Those findings are as follows:

Express Finding Number 1: Climatic. The city is located in a climatic zone with precipitation ranging from fifteen to twenty-six inches per year. Ninety-five percent of precipitation falls during the months of November through April, leaving a dry period of approximately six months each year. Relative humidity remains moderate most of the time. High temperatures in the summer average in the mid-eighty degrees Fahrenheit and in the winter in the mid-fifty degrees Fahrenheit. Prevailing winds in the area are common with gusts up to thirty-five miles per hour. These climatic conditions, along with our topography, necessitate a greater requirement for fire-sprinklers in residential construction, a minimum Class A roof covering and adequate spark arrestors.

Express Finding Number 2: Geological. The city is located in Seismic Design Category D, which is indicative of high seismic vulnerability. The West Napa fault is documented to be present in our city. The area includes various soil conditions and areas with significant movement potential. Buildings and other structures in Seismic Design Category D can experience major seismic damage. These geological conditions necessitate the prohibition of gypsum as a lateral-resisting building element, and the restriction of Portland cement plaster as a lateral-resisting building element to one-story structures of R-3 and U-1 occupancies.

Express Finding Number 3: Topographical. Areas of highly combustible dry grasses, weeds, brush and trees adjacent to structures are common throughout the city. Above-ground electrical power transmission lines are suspended through trees and above large areas of dry vegetation. The arrangement of man-made features around many buildings greatly limits any approach to all but one side of a building. The area immediately adjacent to the eastern border of the city has been classified as high and very high fire severity zones under the Fire and Resource Assessment Program of the California Department of Forestry and Fire Protection. These topographical conditions, along with our climate, necessitate a greater requirement for fire-sprinklers in residential construction, a minimum Class A roof covering and adequate spark arrestors. (Ord. 2019-12 § 2016-12 § 2, 2016)

Section 16.02.060. Amend Section 101.4.1 Gas.

Section 16.02.080. Amend Section 105.5 Expiration.

Section 105.5 is hereby deleted and amended to read as follows:

Every permit issued by the Building Official under the provisions of this code shall expire by limitation and become null and void if the building, structure, equipment or work authorized by such permit is not commenced within twelve (12) months from the date of such permit, or if the building, structure, equipment or work authorized by such permit is suspended or abandoned at any time after the work is commenced for a period of one hundred eighty (180) days.

Before such work can recommence, a new permit shall be first obtained to do so, and the recommence fee shall be one half the amount required for a new permit (i.e. building, electrical, plumbing and mechanical fees only) for such work, provided no changes have been made or will be made in the original plans and specifications for such work, and provided further such suspension or abandonment has not exceeded one year. To renew a permit after expiration for over one year, the permittee shall pay new full permit fee. The maximum life of any permit is three (3) years.

Any permittee holding an unexpired permit may apply for an extension of the time within which work may commence under that permit when the permittee is unable to commence work within the time frame required by this section for good and satisfactory reasons. The Building Official may extend the time for action by the permittee for a period not exceeding one hundred eighty (180) days on written request by the permittee showing circumstances beyond the control of the permittee that prevented action from being taken.

The investigation fee shall not exceed five times the permit fee required by this code. The minimum investigation fee set forth in the fee schedule adopted by this jurisdiction or a lesser fee than the fee resolution may be permitted on the merits of each individual case by the Building Official. The payment of such investigation fee shall not exempt any person from compliance with all other provisions of this code nor from any penalty prescribed by law.

Exhibit B

Section 16.02.040. Findings and determination.

As permitted in Health and Safety Code Section 17958.7, the city of American Canyon finds and determines the local amendments to the 2022 California Building Code are either administrative in nature or reasonably necessary to protect the health, safety and general welfare of the public due to local climatic, geological or topographical conditions. Those findings are as follows:

Express Finding Number 1: Climatic. The city is located in a climatic zone with precipitation ranging from fifteen to twenty-six inches per year. Ninety-five percent of precipitation falls during the months of November through April, leaving a dry period of approximately six months each year. Relative humidity remains moderate most of the time. High temperatures in the summer average in the mid-eighty degrees Fahrenheit and in the winter in the mid-fifty degrees Fahrenheit. Prevailing winds in the area are common with gusts up to thirty-five miles per hour. These climatic conditions, along with our topography, necessitate a greater requirement for fire-sprinklers in residential construction, a minimum Class A roof covering and adequate spark arrestors.

Express Finding Number 2: Geological. The city is located in Seismic Design Category D, which is indicative of high seismic vulnerability. The West Napa fault is documented to be present in our city. The area includes various soil conditions and areas with significant movement potential. Buildings and other structures in Seismic Design Category D can experience major seismic damage. These geological conditions necessitate the prohibition of gypsum as a lateral-resisting building element, and the restriction of Portland cement plaster as a lateral-resisting building element to one-story structures of R-3 and U-1 occupancies.

Express Finding Number 3: Topographical. Areas of highly combustible dry grasses, weeds, brush and trees adjacent to structures are common throughout the city. Above-ground electrical power transmission lines are suspended through trees and above large areas of dry vegetation. The arrangement of man-made features around many buildings greatly limits any approach to all but one side of a building. The area immediately adjacent to the eastern border of the city has been classified as high and very high fire severity zones under the Fire and Resource Assessment Program of the California Department of Forestry and Fire Protection. These topographical conditions, along with our climate, necessitate a greater requirement for fire-sprinklers in residential construction, a minimum Class A roof covering and adequate spark arrestors. (Ord. 2019-12 § 2016-12 § 2, 2016)

The foregoing Ordinance was introduced at a regular meeting of the City Council of the City of American Canyon, State of California, held on the 1^st day of November, 2022 by the following vote:

The foregoing Ordinance was adopted at a regular meeting of the City Council of the City of American Canyon, State of California, held on the 15^th day of November, 2022, by the following vote:

Exhibit B

Section 16.02.040. Findings and determination.

As permitted in Health and Safety Code Section 17958.7, the city of American Canyon finds and determines the local amendments to the 2022 California Building Code are either administrative in nature or reasonably necessary to protect the health, safety and general welfare of the public due to local climatic, geological or topographical conditions. Those findings are as follows:

Express Finding Number 1: Climatic. The city is located in a climatic zone with precipitation ranging from fifteen to twenty-six inches per year. Ninety-five percent of precipitation falls during the months of November through April, leaving a dry period of approximately six months each year. Relative humidity remains moderate most of the time. High temperatures in the summer average in the mid-eighty degrees Fahrenheit and in the winter in the mid-fifty degrees Fahrenheit. Prevailing winds in the area are common with gusts up to thirty-five miles per hour. These climatic conditions, along with our topography, necessitate a greater requirement for fire-sprinklers in residential construction, a minimum Class A roof covering and adequate spark arrestors.

Express Finding Number 2: Geological. The city is located in Seismic Design Category D, which is indicative of high seismic vulnerability. The West Napa fault is documented to be present in our city. The area includes various soil conditions and areas with significant movement potential. Buildings and other structures in Seismic Design Category D can experience major seismic damage. These geological conditions necessitate the prohibition of gypsum as a lateral-resisting building element, and the restriction of Portland cement plaster as a lateral-resisting building element to one-story structures of R-3 and U-1 occupancies.

Express Finding Number 3: Topographical. Areas of highly combustible dry grasses, weeds, brush and trees adjacent to structures are common throughout the city. Above-ground electrical power transmission lines are suspended through trees and above large areas of dry vegetation. The arrangement of man-made features around many buildings greatly limits any approach to all but one side of a building. The area immediately adjacent to the eastern border of the city has been classified as high and very high fire severity zones under the Fire and Resource Assessment Program of the California Department of Forestry and Fire Protection. These topographical conditions, along with our climate, necessitate a greater requirement for fire-sprinklers in residential construction, a minimum Class A roof covering and adequate spark arrestors.
