Fire Hydrant Installations in Los Angeles County

Private fire hydrants · NFPA 24 underground work · California work by Hedrick Fire Protection (C-16 and C-10 licenses)

Public hydrant or private one?

Start with ownership. A hydrant at the curb usually belongs to the water supplier. A hydrant inside your property line, fed by your own fire service main, is often yours. In the City of Los Angeles alone, about 5,000 hydrants are not maintained by LADWP; they belong to LAWA or to private owners. If your hydrant is one of those, you pay for the install, the yearly test and every repair after that.

That's the work we do. A private hydrant job covers the underground main, the valves and the hydrant itself, laid out under NFPA 24 (the standard for private fire service mains and the equipment attached to them).

Your city line decides who reviews the plans

Los Angeles County has 88 incorporated cities. They don't share one fire agency. Here's how it splits:

• Unincorporated areas and County Fire contract cities. The Los Angeles County Fire Department covers all unincorporated land plus 60 contract cities, 59 of them inside the county. Its Fire Prevention Division does new construction field inspections and minor plan checks through North, Central and East regional units.
• City of Los Angeles. LAFD's Fire Development Services section handles plan review, permit approvals and new construction inspections. Requests go through inspect.lafd.org.
• Cities with their own bureau. Burbank is one. There, the city's fire prevention bureau is your contact.

Not sure? Find out whether your parcel sits inside an incorporated city, then ask that city which fire agency reviews its fire protection plans.

Which code edition applies

County Fire territory follows Title 32 of the Los Angeles County Code, which is the County's set of amendments to the 2022 California Fire Code, and contract cities such as Santa Clarita adopt it by reference. The City of Los Angeles keeps its own fire code. A December 2025 City Clerk report covers a proposal to replace it with the 2025 California Fire Code plus city changes. Confirm the edition in force before drawings are final.

The water comes from someone else

The fire agency approves the hydrant. The water does not come from them. Los Angeles County has many water suppliers: LADWP serves the City of Los Angeles, while the County Waterworks Districts (run by LA County Public Works) serve Malibu and Topanga, Kagel Canyon, Val Verde, Acton and the Antelope Valley, including parts of Lancaster and Palmdale. Other areas have other suppliers. Your connection runs through whichever one serves your parcel.

How an installation runs

1. Site review. Where does the hydrant need to sit, and where is the supply?
2. Drawings go to the fire agency for your address.
3. The connection gets coordinated with your water supplier.
4. Underground main, valves and hydrant go in.
5. The system is flushed and tested before the agency's field inspection.

Then it's on your maintenance calendar. NFPA 25 calls for an annual inspection and flow test of private hydrants, and NFPA 291 sets the bonnet color code by flow class so responding crews can read a hydrant's capacity from the paint. We handle that through annual fire hydrant testing in Los Angeles County, fire hydrant maintenance and fire hydrant repair. Building new? Ask about fire sprinkler installation on the same project.

Fire hydrant installation questions

Does the water company install my hydrant?

Street hydrants are usually the water supplier's. A private hydrant on your own fire service main is built by a licensed fire protection contractor. Ours is Hedrick Fire Protection, C-16 licensed.

Who approves a new hydrant in Los Angeles County?

It depends on your address. LAFD handles it inside the City of Los Angeles, County Fire covers unincorporated areas and its contract cities, and some cities, like Burbank, run their own fire prevention bureau.

How often does a private hydrant need testing?

Every year. NFPA 25 calls for an annual inspection and flow test.

Why are hydrant bonnets painted different colors?

NFPA 291 assigns bonnet colors by flow class. Crews read it at a glance.
