Lakewood FAQ
Do existing homes have to retrofit sprinklers?
No. CRC R313 and Title 26 apply to new construction and major additions only. Existing single-family homes have no retrofit mandate, though insurance discounts may make voluntary installation worthwhile.
Who inspects sprinkler systems in unincorporated areas?
LA County Fire Department Prevention Services Bureau handles plan check and acceptance tests. Annual maintenance is the owner's responsibility under NFPA 25, with five-year internal inspections required.
Los Angeles FAQ
Do small additions require sprinklers?
Generally no. Only when a single addition or cumulative additions exceed 50 percent of existing conditioned floor area does LADBS require whole-house retrofit under R313.
Who can service my sprinkler system?
Only a licensed C-16 fire protection contractor may install, modify, or certify residential and commercial sprinkler systems in Los Angeles. Annual tags must be issued by them.
