Long Beach FAQ
Do I need sprinklers when adding a small bedroom?
Usually no. The 50 percent rule and conditioned-area thresholds in CRC R313 govern. Small additions under those thresholds are exempt, but check with Long Beach Development Services before permitting because local amendments can apply.
Can I use plastic CPVC pipe for the sprinklers?
Yes. NFPA 13D allows listed CPVC pipe behind drywall in residential systems. Long Beach Fire Prevention reviews the contractor's hydraulic calculations and listing documentation during plan check.
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.
