Summary
Turlock requires automatic fire sprinklers in any new building or structure whose fire area exceeds 5,000 square feet, and apartment or condo buildings up to four stories can use NFPA 13R systems instead.
An approved automatic fire sprinkler system is required in all new buildings and structures constructed on or after the effective date of this ordinance, notwithstanding the use and occupancy thereof, when any fire area, as defined in the California Fire Code exceeds five thousand (5,000) square feet.
a. Fire area calculations shall include all floors, mezzanine, basements and any attached projections greater than four (4) feet.
b. Structures which are within six (6') feet of each other as measured from the outside walls, or any projection therefrom, or are attached by a breezeway or a covered walkway, the measured floor area of each shall be aggregated.
c. Buildings three (3) stories or more, irrespective of height; including basements, cellars and or mezzanines.
d. Any Group A occupancy as defined in the California Building Code or modified for Group A use.
e. CFC 901.4.4 may not be exercised to add fire walls to avoid the installation of fire sprinklers in new buildings or to existing buildings during remodel/addition.

Full Breakdown
Section 4-3-203 amends California Fire Code § 903.7 to mandate an approved automatic sprinkler system in every new building or structure, of any use, once any single fire area exceeds 5,000 square feet; adjoining structures within six feet of each other have their floor areas combined for this test. Buildings three or more stories, and any Group A assembly occupancy, are covered regardless of size. Existing buildings must add sprinklers when a remodel or addition exceeds 5,000 square feet or when alteration costs exceed half the building's assessed improvement value. Condo and apartment buildings up to four stories can substitute an NFPA 13R system with full attic sprinkler protection.
Violations & Fines
Building without required sprinklers blocks final inspection and certificate of occupancy; the Fire Chief enforces § 4-3-203 through the plan-check and inspection process before permits close out.
