San Bernardino County Fire Protection Services
Fun fact: San Bernardino County is the largest county in the contiguous United States by area — over 20,000 square miles stretching from the busy western valley to the Mojave Desert and the ski slopes of Big Bear. That's a lot of territory. And while most of the 2.2 million residents live in the southwestern part of the county, the fire protection needs span the entire map.

Our licensed technicians provide fire alarm systems, fire extinguisher inspection and certification, commercial kitchen suppression, fire sprinkler installation and maintenance, and fire hydrant testing.

San Bernardino County Fire Codes — What Businesses Need to Know
Like Riverside County, San Bernardino County Fire operates under a cooperative agreement with CAL FIRE. This dual structure means the county fire department enforces both the California Fire Code and local San Bernardino County amendments — and they're thorough about it.
Here are the essentials:
- Fire extinguishers: Annual professional inspections per NFPA 10 and California Fire Code. Monthly visual inspections by building owners are also required.
- Fire alarms: Annual testing per NFPA 72. New installations and modifications need permits from the fire prevention bureau.
- Kitchen suppression: Semi-annual inspections of UL 300 systems per NFPA 96. Every restaurant, commercial kitchen, and food service operation needs to be on this schedule.
- Sprinkler systems: Annual inspections per NFPA 25, with quarterly checks on certain components and 5-year internal inspections for wet pipe systems.
- High-piled storage permits: If your warehouse stores goods higher than 12 feet, you need a permit with specific requirements for sprinkler coverage, aisle widths, and fire department access.
- Mountain community rules: Properties in Big Bear, Lake Arrowhead, and Crestline must comply with additional wildfire-resistant construction standards and defensible space regulations.

County Fire vs. City Fire — Know Your Jurisdiction
San Bernardino County Fire covers unincorporated areas and contract cities. But many of the county's biggest cities run their own fire departments — including San Bernardino, Ontario, Fontana, Rancho Cucamonga, Rialto, Colton, Redlands, Upland, Montclair, and Loma Linda.
Each independent department enforces fire codes within its boundaries and may have unique local amendments. Ontario, for example, has specific fire protection requirements for the massive logistics and warehouse developments near Ontario International Airport. Fontana has enhanced fire code provisions for its booming industrial sector along the I-10 and I-15 corridors.
The requirements are similar across jurisdictions, but the details matter. Call us at (909) 219-9411 and we'll identify exactly who has authority over your property.
Industries That Keep San Bernardino County's Fire Protection Busy
- Warehousing & logistics: Welcome to the Inland Empire — the largest warehouse and distribution market in the United States. Ontario, Fontana, Rancho Cucamonga, Rialto, and San Bernardino are home to tens of millions of square feet of warehouse space. Many modern facilities exceed 1 million square feet and need sophisticated ESFR sprinkler systems, fire hydrant infrastructure, and fire alarm monitoring.
- Manufacturing: Industrial operations in Fontana, Ontario, Colton, and Redlands need industrial-grade fire suppression, hazmat fire protection, and specialized alarm systems.
- Transportation: Ontario International Airport and its logistics hub have specialized fire protection requirements for aircraft hangars and fuel storage.
- Mountain tourism: Big Bear Lake, Lake Arrowhead, and Running Springs have seasonal hotels, restaurants, and ski lodges that need fire protection systems built to handle cold weather — including freeze protection for sprinkler systems.
- Healthcare & education: Loma Linda University Medical Center and multiple university campuses have complex, multi-building fire protection systems.
Our technicians come directly to your location — whether it's your office, warehouse, or home — at no additional travel cost.
Frequently Asked Questions — Fire Protection in San Bernardino County
Why is the Inland Empire such a hot spot for fire protection services?
Because it's the largest warehouse and distribution market in the entire country. The boom in e-commerce has driven construction of hundreds of massive distribution centers across San Bernardino County, each one needing extensive fire sprinkler systems, private fire hydrants, and monitored fire alarm systems. If you build it, you need to protect it from fire — and there's been a lot of building.
What fire protection do I need for a warehouse in San Bernardino County?
The full package: automatic fire sprinkler systems (often ESFR or in-rack systems for high-piled storage), fire alarm systems, fire extinguishers throughout the building, and private fire hydrants on the property. You'll also need a high-piled storage permit from the fire prevention bureau. The specifics depend on what you're storing, how high it's stacked, and how big the building is. Call 1 Pro Fire at (909) 219-9411 for a free assessment.
Are there special fire requirements for businesses in Big Bear or the San Bernardino Mountains?
You bet. Mountain communities are in designated Very High Fire Hazard Severity Zones (VHFHSZ) and Wildland-Urban Interface areas. Businesses need to maintain defensible space, use fire-resistant building materials, and keep all fire protection systems running year-round — including freeze protection for sprinkler systems during those cold mountain winters.
How often should fire sprinkler systems be inspected in San Bernardino County?
Annual inspections are the baseline per NFPA 25 and California Fire Code. But that's not all — quarterly inspections are required for certain components (gauges, control valves, alarm devices), and 5-year internal inspections are needed for wet pipe systems. Think of it as regular maintenance, not a one-and-done thing.
Does San Bernardino County require fire alarm monitoring?
For most commercial occupancies, yes. California Fire Code and San Bernardino County amendments require fire alarm systems to be monitored by a UL-listed central station. This ensures fire signals reach the fire department even when nobody's in the building — which is especially important for those massive warehouses that may be empty overnight.
What's the difference between San Bernardino County Fire and a city fire department?
San Bernardino County Fire (operating with CAL FIRE) covers unincorporated areas and contract cities. But big cities like Ontario, Fontana, Rancho Cucamonga, San Bernardino, and Redlands run their own fire departments with their own fire prevention bureaus. The fire code requirements are similar, but each jurisdiction can adopt local amendments. Call 1 Pro Fire at (909) 219-9411 and we'll tell you exactly who covers your property.
