Does your project need sprinklers?
The fire code makes that call. Whether a building has to be sprinklered depends on its use, its size and how it's built, so the question usually comes up when someone plans a new building, an addition, or a change of use such as an office becoming a restaurant. An addition can pull an existing building into the requirement. So can a new tenant. If you're not sure where your project stands, tell us what you're building and we'll walk through it with you before the drawings are final.
The code your system is designed to
Rancho Palos Verdes adopted the 2025 California Fire Code on November 11, 2025, as part of the 2025 California Building Standards Code, and it took effect January 1, 2026. Local amendments sit in the city's Municipal Code. The city's public notice for that update also covered adopting the Los Angeles County Fire Code (Title 32) as the city's fire code. We draw to the current editions.
Who reviews and approves it
Rancho Palos Verdes has no city fire department. The city contracts with the Los Angeles County Fire Department, and LA County Fire's Battalion 14 provides fire suppression, fire prevention and life safety services across the city. County documents point to more than one Fire Prevention office, so confirm with LA County Fire which one takes your sprinkler plans before you submit. That one call can save a resubmittal.
From water supply to final test
- Water supply. California Water Service (Cal Water) serves Rancho Palos Verdes through the Palos Verdes System of its Rancho Dominguez District, with its district office in Torrance. A sprinkler design is sized to what that supply can deliver at your site. Flow data comes first.
- Design and plans. Pipe sizes, head layout and the riser are worked out from the flow data and the building's use. The plans then go to the fire authority for review.
- Installation. The crew runs the pipe, sets the heads and valves, and builds the riser. Waterflow and valve monitoring usually connect to the building's fire alarm system.
- Testing and sign-off. New piping is pressure tested before the system goes into service, and the fire authority gives its final approval.
Once the system is in service, inspections start. Under NFPA 25 it gets quarterly and annual inspections, plus a 5-year internal pipe assessment and gauge replacement or testing, and California's Title 19 requires a 5-year service and certification by a State Fire Marshal licensed contractor. Our fire sprinkler service in Rancho Palos Verdes covers those visits.
Who may install it
California work for 1 Pro Fire is done by Hedrick Fire Protection. Hedrick holds C-16 (fire protection) and C-10 (electrical) contractor licenses. The California State Fire Marshal also licenses Hedrick under Title 19 for inspection, testing and maintenance of water-based fire protection systems, and that license covers the 5-year certification. One contractor, start to finish.

Sprinkler installation questions
Is fire flow testing available in Rancho Palos Verdes?
Yes. A sprinkler design needs that flow data before layout starts, and our fire hydrant testing in Rancho Palos Verdes page explains how a test works.
Can sprinklers be added to an existing building?
Yes. Retrofits take more planning, because the pipe has to be routed through finished ceilings and walls, often while people are still working in the building.
Will the sprinklers connect to my fire alarm?
Usually. In many commercial buildings, the waterflow switches and valve monitoring report to the alarm panel.
