From unincorporated Spring and Cypress to the Ship Channel cities, we design, install, monitor and inspect systems that are ready for the Harris County Fire Marshal and the county alarm permit office.
Harris County is home to more than 5 million people across roughly 1,707 square miles of land, which makes it the most populous county in Texas. Many of those residents and businesses sit outside any city limits, in unincorporated communities such as Spring and Cypress, where county agencies rather than a city handle permits and inspections.
The first thing to find out is which rules apply at your address. Harris County's Address Search shows a "Law Juris" column, and if it lists "sheriff," you are in unincorporated Harris County. Alarm permits there come from the Harris County Alarm Detail, part of the Sheriff's Office, at 9418 Jensen Drive. Its application lists:
Alarm Masters is a licensed, family-owned Texas company that has been doing this since 1990. We make sure the right permit is in place before we turn a system on, so the Harris County alarm permit is handled from day one.
We are a one-stop shop, so a single team can design, install, monitor, inspect and maintain everything on your property, wherever it sits in the county.
For homeowners in unincorporated Harris County, we install monitored home security covering break-ins, smoke and carbon monoxide, with cameras and app control, and we can help you register under the county's residential permit.
The Harris County Fire Marshal's Office (HCFMO) enforces the adopted county fire code. Its Prevention Division inspects buildings during and after construction and carries out periodic inspections of commercial and public buildings. We do not stand in for the fire marshal, but as a licensed fire alarm company (Texas Fire Alarm License #ACR-1975) we prepare your system so those inspections go smoothly.
It depends on when your building was permitted. HCFMO maps permit dates to International Fire Code editions, and the 2021 edition applies to work permitted from January 1, 2025.
Fire alarm permits in unincorporated areas go through the Harris County Office of the County Engineer. The county requires an addressable fire alarm system, plans must comply with NFPA 72, and plan review takes about 15 business days. Adding five or fewer notification or conventional initiating devices to an existing system needs only a letter, but any change to the panel's program needs a permit and inspection. The county does not recognize "like-for-like" or "one-for-one" swaps on fire alarm systems.
A Certificate of Compliance is required before a facility opens to the public. After that, test, inspection and service reports for fire alarm systems are filed through The Compliance Engine, which HCFMO uses to track compliance and send owners notices. A licensed contractor submits them for you, so your record with the Fire Marshal's Office stays current without extra work on your side.

Harris County mixes the state's largest city, industrial suburbs and fast-growing unincorporated communities, and each brings different rules.
Incorporated cities set their own requirements, so we confirm the right authority for every site before design starts.
Look up your address in Harris County's Address Search. If the Law Juris column says sheriff, you are in unincorporated Harris County and the Harris County Alarm Detail handles your permit. If it lists a city, that city's rules apply, and we can help you check them.
Before the system goes live. The Harris County Alarm Detail's application states that the permit must be issued before the alarm system is activated, and it runs for 12 months from issue. Not receiving a renewal notice does not excuse a late renewal, so it is worth putting the renewal date on your calendar as soon as the permit arrives. Running without a permit can also bring a citation.
HCFMO's Prevention Division inspects buildings during and after construction and periodically inspects commercial and public buildings. Before a final inspection, a new facility needs its permit from Harris County, and pre-inspection documents are reviewed by the fire marshal. We prepare the system and documents so you are ready on inspection day.
Sometimes. Adding five or fewer notification or conventional initiating devices to an existing system needs only a letter describing the work, but any change to the panel's program requires a permit and inspection. Harris County does not recognize like-for-like swaps on fire alarm systems, so ask us before any work starts.
Service providers submit test, inspection and service reports to HCFMO through The Compliance Engine, which tracks fire alarm systems among other fire protection systems. Contractors register with the system and file a report after each visit. When we inspect your system, we handle the submission.
Yes. Residential permit holders who are 65 or older still need a permit, and the application asks for your date of birth. Like every Harris County alarm permit, it has to be issued before the system is activated and renewed every 12 months, and we can help you get the paperwork right.
