Fire Sprinkler Installation in Norco

Does your Norco building need sprinklers?

In Norco, the answer starts at 3,600 square feet. The city adopted the 2025 California Fire Code with local amendments in Municipal Code Chapter 15.09, and its amended version of CFC 903.2 (section 15.09.260) sets when a sprinkler system is required.

• New buildings of 3,600 sq ft or more, in any occupancy.
• All new one- and two-family dwellings.
• Existing buildings over 3,600 sq ft, when the use changes, a fire wall is removed, or an addition of 50% or more brings the total past 5,000 sq ft.

Changing the use of an older building? Check that last line first. It catches owners who assumed only new construction was affected. If you can't tell which rule applies to your project, ask the fire marshal's office before design begins, because a change on paper costs far less than a change in pipe.

Sized to 90% of the water supply

Norco caps sprinkler demand. Under section 15.09.270, a hydraulically calculated system may not use more than 90% of the available water supply capacity. That margin drives pipe sizes, head spacing and how many heads a design area can carry.

The City of Norco owns and runs its own water utility through the Public Works Water Utility Division. Most designs start from a hydrant flow test, which measures static and residual pressure at a measured flow using the method in NFPA 291. Good supply data means fewer surprises at plan review. If your site has private hydrants, our annual fire hydrant testing in Norco page covers how those are tested and inspected.

Who reviews the plans

Norco has no city fire department. After a 2011 council vote, the city began contracting with CAL FIRE/Riverside County Fire Department for fire and emergency response. Plan review, construction inspections and fire and life-safety inspections for contract cities, Norco included, go through the Riverside County Fire Department's Office of the County Fire Marshal.

Its Norco Eastvale Fire Marshal's Office is at 3902 Hillside Avenue, Norco, CA 92860 (951-737-8097). Ask that office about submittal requirements, plan check and witness fees before you set a schedule. The fees can change.

How an installation usually runs

1. Scope: which code trigger applies, what the building is used for, and what the space stores.
2. Supply: flow data for the connection that will feed the system.
3. Design: layout and hydraulic calculations kept within Norco's 90% limit.
4. Submittal: drawings and calculations go to the County Fire Marshal for review.
5. Install: piping, heads, valves and the riser, built to the approved plans.
6. Acceptance: the new piping is pressure tested and the inspector signs off.

The order rarely changes. The time each step takes depends on plan review, the size of the building, and whether the space is occupied while we work.

After the system is in

A new system starts its service schedule on day one. NFPA 25 calls for quarterly and annual inspections, and California's Title 19 requires a 5-year service and certification by a contractor licensed by the State Fire Marshal. Our California work is done by Hedrick Fire Protection, which holds C-16 (fire protection) and C-10 (electrical) contractor licenses and is licensed by the State Fire Marshal under Title 19 to inspect, test and maintain water-based fire protection systems.

So far, the sprinkler calls we've had from Norco have been about that ongoing work. People have asked about missing spare heads, escutcheon rings written up by the fire marshal, and a 5-year sticker coming due. Our fire sprinkler service in Norco page covers those visits. Restaurant owners can also see restaurant sprinkler inspections, and if your building also needs a monitored system, see fire alarm work in Norco.

Sprinkler installation questions from Norco

Does a new single-family home in Norco need sprinklers?

Yes. Norco's amendment to CFC 903.2 requires sprinklers in all new one- and two-family dwellings, whatever their size.

My existing building is over 3,600 sq ft. Do I have to retrofit?

Only if something triggers it. The triggers are a change of use, removing a fire wall, or an addition of 50% or more that brings the building past 5,000 sq ft.

Is your company licensed for fire sprinkler work?

Yes. Hedrick Fire Protection does the work under its C-16 and C-10 licenses and its State Fire Marshal Title 19 license.

Who sets the permit and witness fees?

The County Fire Marshal's Norco Eastvale office handles plan review and inspections for Norco. Call 951-737-8097 for current fees.
