Commercial Fire Alarm Contractors Across Greater Houston

Vector Fire matches commercial properties anywhere in the Greater Houston metro with vetted, licensed fire alarm contractors — for installation, inspection, monitoring, service, and repair. We're a referral service, not a contractor: tell us your property and location and we connect you with the right pro for your area. Matching is free, with no obligation.

Find Coverage by Region

Greater Houston spans several counties and fire-marshal jurisdictions. We organize our network by region so you reach a contractor who knows your local authority having jurisdiction (AHJ), permit process, and code requirements. Coverage is active across the metro and expanding region by region.

North Houston — The Woodlands, Conroe, Spring, Tomball & Montgomery County (Montgomery County Fire Marshal).
Northeast Houston — Humble, Kingwood, Atascocita, Porter, New Caney, Crosby & the Lake Houston area (Harris County Fire Marshal / ESDs).

Expanding across the rest of Greater Houston — Northwest, West, Southwest, South, Southeast, East, the Inner Loop, and Downtown. Coverage is active metro-wide through our vetted network now; dedicated local pages for these areas are rolling out. Need one of those areas today? Get matched and we'll connect you.

Why Local Jurisdiction Matters in Greater Houston

Greater Houston isn't one fire-code jurisdiction — it's dozens. A commercial fire alarm permit, plan review, and acceptance inspection are handled by whichever authority having jurisdiction (AHJ) governs your exact address, and the metro spans five counties (Harris, Montgomery, Fort Bend, Brazoria, and Galveston), the City of Houston, and a long list of incorporated cities and Emergency Services Districts.

In practice, three offices handle most commercial fire alarm work across the metro: the City of Houston Fire Prevention Bureau (832-394-8800) inside Houston city limits — which, thanks to annexation, includes areas that don't feel like "Houston," such as Kingwood; the Harris County Fire Marshal (713-755-4626) for unincorporated Harris County; and the Montgomery County Fire Marshal (936-760-6800) to the north — alongside the Fort Bend, Brazoria, and Galveston county marshals and individual city fire marshals (Conroe, Humble, Tomball, Sugar Land, Pearland, and more).

Filing with the wrong office is one of the most common causes of a delayed permit or failed acceptance inspection. Organizing our network by region — and matching you with a contractor who already works your specific jurisdiction — is how we keep your project on schedule. Pick your region above, or get matched and we'll route you correctly.

Greater Houston Fire Alarm Coverage — FAQ

Does Vector Fire cover all of Greater Houston?

Yes. Our vetted, licensed contractor network covers commercial properties across the entire Greater Houston metro. North Houston and Northeast Houston have dedicated local pages today, and the remaining regions — Northwest, West, Southwest, South, Southeast, East, the Inner Loop, and Downtown — are covered now and getting their own local pages as we roll them out.

How do I know which fire marshal has jurisdiction over my property?

It depends on your exact address. Inside Houston city limits (including annexed areas like Kingwood) it's the City of Houston Fire Prevention Bureau; unincorporated Harris County is the Harris County Fire Marshal; Montgomery County and incorporated cities have their own offices. When you get matched, we connect you with a contractor who already works your jurisdiction, so plans go to the right office.

What does it cost to get matched with a contractor?

Nothing. Vector Fire is a referral service — matching is free, with no obligation. You receive a quote and contract directly with the contractor you choose. We don't perform the work and don't profit from it, so the match is unbiased.

Which services does the Greater Houston network cover?

Commercial fire alarm installation, inspection, monitoring, service and repair, mass notification, emergency/exit lighting, and BDA/ERRCS — across every region of the metro. See our cost guides for honest price ranges on each.
