Summary
Every townhouse built in Hanford must include an automatic residential fire sprinkler system under the city's amendment to California Residential Code § R313.1. Existing townhouses only trigger the requirement when a remodel exceeds 50 percent of the building's current replacement cost, as determined by the Hanford Building Official using the Building Valuation Data Table.
Subsection R313.1 Townhouse automatic fire sprinkler systems; of Section R313, of said California Residential Code, Part 2.5, is hereby amended to read as follows: R313.1 Townhouse automatic fire sprinkler systems. An automatic residential fire sprinkler system shall be installed in townhouses. Exception shall read: An automatic residential fire sprinkler system shall be required when any remodeling exceeds 50% of the current replacement cost of the existing building or structure as determined by the City of Hanford Building Official, using the current Building Safety Journals "Building Valuation Data Table." (See Express Finding No. 12)

Full Breakdown
Hanford Municipal Code § 15.02.030(B)(5) rewrites Section R313.1 of the California Residential Code, Part 2.5, to read that an automatic residential fire sprinkler system shall be installed in townhouses, with a single exception for existing construction: a system is only required when remodeling work exceeds 50% of the building's current replacement cost, calculated by the City of Hanford Building Official using the current Building Safety Journal's Building Valuation Data Table (Express Finding No. 12).
The mandate reaches beyond townhouses. The parallel amendment at § 15.02.030(B)(6), covering R313.2 for one- and two-family dwellings, applies the identical 50%-remodel exception, and § 15.02.030(D)(4) separately amends California Fire Code § 903.1 to require an NFPA 13R automatic fire extinguishing system in every Group R-1 and R-2 occupancy except hotels, with a full NFPA 13 system required for Group R-1 and R-2 hotels. Section 15.02.030(D)(5) extends the NFPA 13R minimum to all Group R-1 occupancies and air-space condominiums regardless of square footage. Under § 15.02.030(D)(2)(a), whenever the Fire Code and Building Code amendments diverge in stringency, the more restrictive requirement controls.
Any required sprinkler installation of 21 or more heads must also tie into a central station alarm circuit under § 15.02.030(D)(11), and Hanford requires operable fire hydrants and fire apparatus access roads in place before construction begins under §§ 15.02.030(D)(2) and 15.02.040(D)(2).
Violations & Fines
Building or occupying a townhouse without the required sprinkler system is enforced as an infraction under Hanford Municipal Code § 15.02.080, punishable as set out in Government Code § 36900(b). A Building Official's determination on whether a remodel crosses the 50% replacement-cost threshold can be appealed in writing to the city council through the city clerk within 14 days under Hanford Municipal Code § 1.08.010.
