Summary
Ventura's Fire Code Appendix R requires automatic fire sprinklers in every new building over 500 square feet, and in all new townhouses and one- and two-family dwellings regardless of size. Section 14.10.020(SS), Appendix R103.2, exempts only specific small detached carports, garages, car washes, gas station canopies and certain parklets.
R103.2 New Buildings/Structures. Approved automatic sprinkler systems shall be provided in all new buildings or structures, to be occupied by Groups A, B, E, F, H, I, L, M, R, S, U, or mixed-use occupancy classifications when over 500 sq. ft. in floor area. For all new townhouses and one- and two-family dwellings, an automatic fire sprinkler system shall be installed per the California Residential Code. Exceptions:
1. Detached U occupancy carports used for motor vehicle storage intended for no other use or storage that are open on sixty percent (60%) of exterior walls. Such carports are limited to three thousand (3,000) square feet or less in floor area and will be constructed entirely of noncombustible materials. Treated lumber is not allowed.

Full Breakdown
020(SS), is Ventura's local sprinkler mandate layered on top of the state code. 2 requires approved automatic sprinkler systems in all new buildings or structures occupied by Groups A, B, E, F, H, I, L, M, R, S, U, or any mixed-use classification once the building exceeds 500 square feet of floor area, and it separately requires sprinklers in every new townhouse and every new one- and two-family dwelling regardless of square footage, installed per the California Residential Code. 2; gas station canopies unless the base Fire Code otherwise requires sprinklers; and parklets within the defined Main St.
Moves area. 3 extends the mandate to existing buildings once cumulative additions push a residential structure's floor area to 100 percent or more of its November 6, 1991 size, or push any other existing building past 5,000 square feet with additions exceeding 10 percent of the original area or 2,500 square feet, or where a change of occupancy makes the use more hazardous.
Violations & Fines
Building or occupying a new structure that falls under Appendix R without the required automatic sprinkler system is a Fire Code violation, prosecuted as a misdemeanor under amended CFC Section 113.4, with fines and any jail time set by the Municipal Code and City Council resolution and each day of noncompliance counted as a separate offense. The Building Official and Fire Marshal jointly enforce the sprinkler requirement through the plan check and inspection process before a certificate of occupancy can issue.
