Decide who gets in, where and when, from your phone. We design, install and support commercial access control across Houston, from single office doors to gated yards and apartment communities.

A lost key in Houston is rarely just one door. It is the front entrance, the server closet, the supply room and the gate, and rekeying all of them takes time you would rather spend running the business. Commercial access control replaces those keys with credentials you can issue, change or cancel in seconds, and it keeps a record of every door that opens.
That record matters more here than in most cities. Houston properties are big, spread out and often busy around the clock: a distribution yard on the east side, a medical office off the Southwest Freeway, a multi-tenant tower with a dozen companies on different schedules. Access control systems in Houston have to handle shift changes, contractors, deliveries and after-hours visitors without leaving a door propped open.
Alarm Masters has been designing and installing security systems in Texas since 1990, and access control is one of the systems we are asked about most. We handle the whole job ourselves, from the site walk and hardware selection to installation, programming, training and ongoing service, so you are never stuck between an installer and a software vendor.
Every system we install is designed around how your building is used. Common pieces include:
Your burglar alarm, video and access control can all run in one app, so arming the building and locking the doors become a single routine. Already have readers on the wall? We can take over and support an existing access control system rather than starting from scratch. Find the full feature list on our access control page, or see how we approach multifamily, HOA and gated communities and warehouse and industrial sites.
Locking things down is only half the job. In Houston, the Fire Marshal's Office also needs to be able to get in, and access control designs that ignore that end up failing plan review or inspection.
Fire department access is required under Section 503 of the 2021 Houston Fire Code. The Houston Fire Department's own guidance says that, with some exceptions, every portion of a building must be within 150 feet of an approved fire department access route, and fire lanes have to stay clear with no parking or storage. The Fire Marshal's Office carries out plan reviews and on-site inspections of fire department access gates, and its Life Safety Bureau Standard 04 calls for access gates to be at least 20 feet wide with Knox key entry.
For a Houston property with a gated entrance, that means the gate operator, the width of the opening and the emergency override have to be planned together, not bolted on afterwards. Inside the building, electrified door locks also need to be coordinated with the fire alarm system so doors behave the way the approved design says they should during an alarm.
Because Alarm Masters holds both a Texas security license (#B-06372) and a Texas fire alarm license (#ACR-1975), we can design the access side and the fire alarm side as one system. Our custom system design team prepares the layout with code review in mind, which keeps surprises out of your inspection.
The access problem looks different depending on where in Houston your property sits.
Along the Houston Ship Channel, more than 200 private terminals operate alongside the eight public ones run by Port Houston, and the industrial businesses that support them depend on controlled gates, badge readers at warehouse doors and clear records of who came and went. For these sites, readers that survive Gulf Coast heat and humidity and gates that tie into cameras are the starting point.
In Uptown around Post Oak Boulevard, and in the Energy Corridor along the Katy Freeway, offices are often in shared buildings. Tenants need their own doors and suites managed separately from the lobby, and cloud access control lets an office manager handle that without calling building security for every change.
Apartment communities and HOAs across Houston use access control for amenity rooms, pools, package rooms and perimeter gates. Mobile credentials are popular here because residents already carry their phones and property managers can switch access on move-in day and off at move-out.
For Houston homeowners, the same idea scales down to smart locks you can open from the app for a dog walker or a contractor, alongside your home security system.
Yes. With a cloud platform such as Brivo or Eagle Eye, each site appears in the same dashboard, so you can add an employee once and give them the right doors at every location. Changes take effect straight away, which is useful when you have offices or yards in different parts of Houston.
It has to, and we design for it from the start. The Houston Fire Marshal's Office reviews and inspects fire department access gates, and its Life Safety Bureau Standard 04 calls for gates at least 20 feet wide with Knox key entry. We plan the gate, operator and override with those requirements in mind.
Yes. Mobile credentials work on the same readers as cards and fobs, and you can mix them if some people prefer a card. Phones are harder to lend out than a fob, and you can revoke access remotely the moment someone leaves the company.
Not always. We can take over support of many existing access control systems, and during the site walk we check which readers, controllers and locks can stay. If something is at the end of its life, we will explain why and show you the options.
We bring burglar alarm, video and access control into one app. You can see a clip of every door event, arm the building when the last person badges out and get alerts when a door is forced or held open too long.
For most communities, yes. It controls who can use the pool, gym, mail and package rooms, and it lets managers switch access on and off as residents move in and out without rekeying. Gates, amenity doors and intercoms can all be handled in the same system.
