Garden Grove FAQ
Do I need to retrofit sprinklers in my existing home?
No, unless you do a substantial remodel or addition exceeding fifty percent of the existing floor area. Voluntary retrofits qualify for insurance discounts in many cases.
Who maintains my home fire sprinkler system?
The homeowner is responsible for annual visual checks and ensuring the main shut-off remains open. Hire a NICET-certified contractor for service every five years.
Santa Ana FAQ
Do I need sprinklers for an addition?
If your addition adds more than 50 percent of the existing floor area, sprinklers are typically required throughout the home, not just the new portion, under CRC R313 amendments.
Are ADUs required to have sprinklers?
California prohibits requiring sprinklers in an ADU unless the primary residence already has them. Check with Santa Ana Planning early in the design process for confirmation.
