Business and home security for Galveston County's largest city, with fire alarm design, inspection and monitoring that keeps you in step with League City's fire marshal.

League City is now home to close to 119,000 people, making it the largest city in Galveston County. It sits on the southern shore of Clear Lake and is bordered by water on three sides, with Clear Creek, Galveston Bay and Dickinson Bayou framing the city. Interstate 45 carries traffic through the middle of town, and the planned Grand Parkway Segment B is set to begin at I-45 in League City.
For business owners, that growth brings a familiar set of questions. How do you protect a new storefront, a medical suite or a marina office with a system that fits the way the space is really used? How do you keep a fire alarm inspection ready when the building is busy every day? And how do you keep false alarms from becoming a headache once your system is live?
Alarm Masters answers those questions for Texas businesses and families every day. Our family business dates back to 1990, and today more than 5,000 clients count on our monitoring after over 3,000 completed projects. Design, installation, monitoring, inspection and maintenance all sit under one roof, and if something needs fixing, we guarantee a turnaround within 48 hours. Homeowners get the same care, from monitored alarms to smart locks and cameras.
A commercial burglar alarm paired with video surveillance gives you alerts and footage in one app. Live video monitoring and video verification help confirm a real intrusion before police are dispatched.
Offices, clinics and multi-tenant buildings can replace keys with cards, fobs or phones. Our access control systems from Brivo, HID, Salto and Assa Abloy let you change permissions in seconds.
We engineer and install code-compliant fire alarms through our custom design process, working to the 2021 codes League City has adopted.
League City expects monitored fire systems to be serviced every year and records kept. Our licensed technicians test every device to NFPA 72 during fire alarm inspection visits and hand you the report.

Both of the city offices that matter most for your system are based at 555 W Walker Street. The League City Fire Marshal's Office works to assure compliance with fire and building codes, issues permits, reviews plats and plans and investigates fires. The city works from the 2021 International Fire Code, the 2021 International Building Code and the 2021 edition of the NFPA Life Safety Code, along with its own Code of Ordinances. Plan submittals and operational permits are handled electronically through the city's online portal.
The fire marshal's guidance on common violations is direct. The building owner is responsible for keeping fire and life safety systems operable, records of inspection, testing and maintenance must be kept, and a monitored system needs to be serviced annually. If your last inspection report is hard to find, that is the first thing to fix.
The Police Department's False Alarm Unit runs the alarm permit program. Anyone operating an alarm system inside city limits must register it. Registration categories cover residences, commercial properties and financial institutions, and you can register online, by mail or in person at 555 W Walker Street. The unit tracks false alarms over a rolling 365-day period, and the first three in that window fall within the city's allowance. Activations that are not false never count against you, and appeals must be made in writing within 10 business days.
We help clients stay on the right side of both offices, keeping inspection records current and using verification and training to keep false alarms down.
The League City Historic District, with Victorian homes and buildings tied to the city's founding families, mixes shops and restaurants around Founder's Square, League Park and Helen's Garden. Older buildings like these usually call for discreet cameras and wireless devices that respect the character of the property. Our retail and restaurant pages explain what we typically recommend.
On the water, South Shore Harbour is described as the largest full-service waterside resort and conference center in Southeast Texas, with 237 rooms, and the city ranks third in the country for boating anchorage. Hospitality and marine businesses often need camera coverage for docks and parking, plus access control for staff-only areas.
League City is within 50 miles of two airports, a spaceport and four major marine ports at Houston, Galveston, Texas City and Freeport, and its location near NASA Johnson Space Center supports growth in medical, aerospace and professional services. Distribution and flex users should see our warehouse and industrial page.
Developers have claimed most of the city's remaining undeveloped land for housing, with thousands of homes planned on the west side. Explore HOA security, multifamily and education solutions.
Alarm permits are handled by the League City Police Department's False Alarm Unit at 555 W Walker Street. You can register online, by mail or in person. Registration covers residences, commercial properties and financial institutions, so make sure your system is registered under the right category.
The League City Fire Marshal's Office states that a monitored system needs to be serviced annually, and that inspection, testing and maintenance records must be kept. We schedule annual NFPA 72 inspections and provide the reports.
No. The city says an alarm activation that is not false is never held against you. Only false alarms count, and the first three in a 365-day period fall within the city's allowance, so a well-maintained system with video verification keeps you comfortably clear.
League City lists the 2021 International Fire Code, the 2021 International Building Code, the 2021 NFPA Life Safety Code and its own Code of Ordinances, among other standards. Our fire alarm designs are prepared with those codes in mind.
Yes. Waterfront sites usually benefit from cameras covering docks and parking, access control on staff areas and a monitored alarm. We plan device placement after a site walk so the system suits your layout.
We do. Our residential systems include monitored burglar alarms, smoke and carbon monoxide monitoring, indoor and outdoor cameras, and smart locks and lighting you can run from your phone. Remember to register your home alarm with the city's False Alarm Unit under the residential category.
