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.
Palmdale 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.
