Where three counties meet, one alarm company that knows the lines

The City of Katy sits where western Harris, northern Fort Bend and southeastern Waller counties meet, around 30 miles west of downtown Houston on Interstate 10. It began as a railroad town on the Missouri-Kansas-Texas line, became known for rice farming, incorporated in 1945 and counted 21,894 residents in the 2020 Census. The wider Greater Katy area was home to roughly 375,000 people that same year.

That split geography is the first thing a Katy business owner should understand about fire and security systems. Who reviews your fire alarm, who inspects your building and which agency answers your burglar alarm can all change depending on whether you are inside the city or out in unincorporated Cinco Ranch. Alarm Masters works right across the area, so you get the right answer for your address rather than a generic one.

Alarm Masters is family-owned and has been at this since 1990, and our crews have finished more than 3,000 projects. Design, installation, monitoring, inspection and upkeep all come from the same team, with businesses as our main focus and homeowners very welcome.

Services

What we install and monitor in Katy

Fire alarm installation, inspection and testing

Katy's fire marshal lists expired fire alarm inspections among the most common reasons a facility fails its annual fire inspection. We install code-compliant fire alarm systems and keep NFPA 72 inspections current, so that never becomes your problem.

Cameras for big sites

Distribution, retail and office sites along I-10 cover a lot of ground. Video surveillance with AI video monitoring and video verification helps you keep an eye on yards, docks and parking fields without someone watching screens all night.

Access control, gates and intercom

Cloud-managed access control with cards, fobs or phones, gate control, and intercom for reception and deliveries, using trusted brands such as Brivo, HID, Allegion and Salto.

Burglar alarms and monitoring

Monitored intrusion alarms with cellular communicators, plus around-the-clock monitoring of fire, burglar and video from a single provider.

Paging, design and repair

PA and emergency notification for warehouses, schools and churches, custom system design, and service and repair on a 48-hour guaranteed turnaround, including systems someone else installed.

Katy homes

Around-the-clock alarm monitoring for your family and pets, smoke and CO alerts, a video doorbell and floodlight cameras for the driveway, and smart locks and thermostats you control from your phone. Find out more on our residential page.

Codes, permits and compliance

Katy Fire Marshal inspections, and what changes outside city limits

Inside city limits, fire code inspections, violation reports and fire investigations are handled by the City of Katy Fire Marshal's Office, which works from Fire Station 1 on Avenue D. Its staff are licensed peace officers through TCOLE and hold state arson investigator certifications.

If you run a day care, assisted living community, nursing home, hospital or similar licensed facility, you schedule an annual fire inspection with that office, and it asks that every fire protection system already carry a current inspection from its service company before you book. Expired sprinkler, fire alarm and kitchen hood inspections, blocked exits, extension cord misuse and missing or outdated Knox Box keys are the usual failure points. New businesses and changes of ownership start with the city's Building and Permits department instead.

Outside the city, the rules shift. Most of Cinco Ranch lies in unincorporated Fort Bend County, where the Fort Bend County Fire Marshal is the fire code authority for commercial buildings and the Sheriff's Office runs an annual permit program for monitored alarm systems. Properties on the Harris County side follow Harris County processes. We confirm the jurisdiction during our Discovery and Site Walk, so permits, inspections and monitoring are set up correctly from the start. Our Fort Bend County page covers the county rules in detail.

Areas and industries

Katy business districts, landmarks and Cinco Ranch

Retail and entertainment cluster around Katy Mills, which opened in 1999 and anchors an area that includes the Katy Boardwalk District and Typhoon Texas Waterpark. High footfall, long opening hours and big parking lots make cameras and access control a priority for retail and restaurant operators here.

Industry follows the interstate. A one-million-square-foot Amazon distribution center sits on 84 acres near I-10 and Woods Road on the city's western edge, and more industrial and warehouse projects have followed along the I-10 corridor. Katy ISD is the area's largest employer at around 12,000 staff, and major energy employers in and near the Energy Corridor round out a workforce that keeps warehouse, education and office security in steady demand.

Cinco Ranch, about 10 miles southeast of the city, is one of Greater Katy's best-known master-planned communities. It opened in 1991, now spans about 8,092 acres with more than 15,000 homes, and centers on LaCenterra, a 34-acre town center of shopping and dining. Pupils attend Katy ISD, and fire protection across much of the community comes from the Willowfork Fire Department, run by Fort Bend County Emergency Services District No. 2. For homeowners and HOAs here we offer monitored alarms, cameras and gate and amenity access control.

Questions

Frequently asked questions

Is my Katy business inside city limits or in an unincorporated area?

A Katy mailing address does not always mean the City of Katy. Communities such as Cinco Ranch are part of Greater Katy but sit outside the city, mostly in unincorporated Fort Bend County. We check your exact address so your fire alarm permits and alarm registration go to the right office.

Why do Katy businesses fail their annual fire inspection?

According to the Katy Fire Marshal's Office, the usual culprits are expired sprinkler, fire alarm and kitchen hood inspections, blocked exits, extension cord misuse and missing or outdated Knox Box keys. Keeping your fire alarm inspection current with a licensed company takes one of those off the list.

Do Cinco Ranch homeowners need a Fort Bend County alarm permit?

If your home is in unincorporated Fort Bend County and has a monitored alarm, the Sheriff's Office requires an annual permit. Renew it on time each year, because a lapsed permit has to be applied for again from the start rather than simply renewed.

Can you secure a large distribution or warehouse site along I-10?

Yes. Big sites usually combine perimeter and dock cameras with AI video monitoring, gate and door access control, and a monitored intrusion alarm. Everything runs from one app, which makes life easier for managers covering several shifts.

Who do I contact for a fire inspection when opening a new business in Katy?

New businesses and changes of ownership inside the city start with the City of Katy Building and Permits department. Licensed facilities such as day cares and nursing homes book their annual inspection with the Fire Marshal's Office once their fire protection systems have current inspections.

Can you monitor alarm systems on all sides of the Katy area?

Yes. We serve the greater Houston area, so a property on the Harris, Fort Bend or Waller side of Katy can be monitored and serviced by the same team, often by taking over the system you already have.
