Aircraft Hangars Built as Texas Metal Buildings
Before anyone picks a door or pours a slab, a hangar starts with a question about the airplane: how wide, how tall, and where does it sit when the tow bar comes off? A single-engine owner wants a box with room to walk around the wings. A flight school wants three bays and a classroom. A maintenance shop wants a clear 100 feet with no columns and a crane rail overhead. Each of these is a metal building, and none of them is the same metal building.
We design, supply and erect pre-engineered aircraft hangars across Texas, from private box hangars to corporate and maintenance buildings. The appeal is easy to explain. A rigid frame can span the width of a wingspan without interior columns, steel goes up quickly, and the building can be sized to the next aircraft you plan to own rather than the one you have now.
What follows is how we approach hangar work: what we need to know up front, how the frame and the foundation are shaped, what the permit and fire reviews look at, and where a Texas airport site can surprise you.
What a hangar package includes
A hangar package is more than a shell. The primary frame is a clear span rigid frame, often with a wide end wall opening for doors, and the secondary steel is sized for that opening. Wall panels and roof panels are chosen for the climate and the use, with insulation for owners who work in the building or store avionics and paint. The slab needs hardened surfaces, drains and slopes that suit aircraft and fluids. Inside, many owners want a mezzanine, an office, a restroom, a workshop corner and a few hundred square feet of storage.
We price all of that as a single scope when the owner wants one contract, and we break it out when the airport requires a separate lease-hold improvement budget. The door is the largest single item, which is why overhead and hangar doors get their own planning conversation before steel is ordered.
Airports across the state, and what they ask of a builder
Texas has airports of every size, and what each one wants from a builder is different. McKinney National Airport is a general aviation field that the city bought in 1979. Its recent history includes a general aviation terminal expansion in 2023 and a city approval in early 2025 of a commercial airline terminal. In Fort Worth, four airports sit inside the city limits, including a cargo-heavy airport in the north and a smaller field close to the downtown. In San Antonio, Port San Antonio spreads over 1,900 acres on the West Side, and aircraft maintenance operators work there alongside rail and truck logistics.
Whether a hangar sits in McKinney, Fort Worth or San Antonio, the owner may be leasing ground, working to a master plan with design standards, and dealing with an airport manager who has to approve the plans. We have built the habit of asking for those standards before drawing anything, because a hangar that meets the code but not the airport's color, setback or roof pitch rules gets sent back.
Fire protection, accessibility and local review
Hangars carry their own fire protection requirements. The type of fire suppression depends on the size of the building, the aircraft inside and whether fueling or maintenance takes place. The national standard for aircraft hangars is a common reference, and the local fire marshal decides how it applies. Foam or sprinkler systems, floor drainage, separation walls and electrical classification near fuel all affect the layout, and they are easier to handle on paper than in a finished building.
The building code set at the municipal level is the International Building Code unless a city adopts later editions by ordinance, so we confirm what the local office actually enforces. Projects with an estimated cost of $50,000 or more must also be registered with the state accessibility program, which reviews drawings for the Texas Accessibility Standards. Restrooms, parking and routes to the office all fall under that review. We collect the airport's approval, the building permit and the state registration in one tracking sheet so none of them is the last surprise.
What we manage most closely
We supervise and inspect the steel and panel erection, and that matters on a hangar because the tolerances at the door opening are tight. The erection crews we schedule set the columns, the rafters, the endwall framing and the girts, and they square the frame before the door installer arrives. They also hang the wall and roof panels and the trim that keeps rain out of the track. When the owner wants to use a local concrete contractor, we coordinate the slab through our anchor bolt and foundation process and verify the work.
Specialty items such as fire suppression, electrical service and fuel systems go to licensed trades. We schedule them so wall panels are not cut twice. For hangars that need more than one bay, we often use the same framing approach found in our clear span buildings, with a wide frame in the middle and lower sheds on the sides for offices and storage.
Site conditions that change a hangar design
Airport sites are flat, open and windy. That is great for planes and tough on buildings, because a hangar with a big opening collects wind inside it when a door is open. The frame engineer designs for that case, which often calls for heavier columns and bracing than a closed shop of the same size would need. Soil conditions vary widely, and many airfields sit on fill or expansive clay, so the foundation design rests on a geotechnical report.
Height limits and approach surfaces are another airport-specific item. The FAA may need a filing for a taller structure close to a runway, and the airport may impose its own limits. We check these before the frame is sized. An extra four feet of eave height can be cheap in the shop and impossible at the site.
Lead times and a realistic calendar
A small box hangar can go from signed contract to finished building in a few months if the airport approval is in hand. The slowest items tend to be the steel package and the doors, and both are ordered early. Larger or multi-bay buildings take longer because of foundation work, fire protection design and inspections.
We give owners a calendar with two kinds of dates: the ones we control, such as erection and panel installation, and the ones we depend on, such as steel delivery and city review. When the schedule moves, we tell the owner and adjust. For an aviation business that needs to move aircraft in by a certain month, that honesty is worth more than a promise. Our aircraft hangar page lists the building types we handle most often.

Common Questions
How big should my hangar be?
Start with the wingspan, add clearance on both sides, and then add depth for the tail and tug. Many owners find a slightly larger building costs little extra per square foot and gives room for a workbench, tools and a second aircraft later. We draw two or three sizes and price them side by side.
Can I build a hangar on leased airport ground?
Yes, and it is very common. The airport will have a lease, a design standard and a plan review. We start by asking for those documents, since they govern setbacks, colors, height and fire protection. A well prepared package gets approved faster.
Do I need fire suppression in a private hangar?
It depends on size, use and the local fire marshal. Small private hangars may have limited requirements, while larger or multi-aircraft buildings often need sprinklers or foam systems. Ask early, since it changes the water service, drainage and cost.
How long does a hangar take to build?
Once steel is released, erection of a small hangar usually takes a few weeks. The calendar before that, covering airport approval, permit, foundation and fabrication, is longer and varies by site. We lay out all phases for you at the start.
Can you add a hangar to an existing building?
Often yes. The question is whether the existing structure and slab can carry the new loads, and whether a door can be installed where you want it. We do an inspection and an engineering review first, then give a firm price for the addition.
