Every hangar owner eventually asks some version of the same question. Can I store the boat in here? Can I run my consulting business out of the office in the corner? Can I let a friend do maintenance on his airplane in my space?
At a public use airport that has taken federal grant money, the answers are not up to the airport manager’s mood. They are shaped by a specific FAA policy, a set of grant assurances the sponsor signed, and a document called the airport’s minimum standards. Here is how those three pieces fit together.
The governing idea: hangars are for aeronautical use
The FAA issued its final Policy on the Non-Aeronautical Use of Airport Hangars in June 2016, effective June 9 of that year. The logic behind it is straightforward. Federal money built or supported a lot of this infrastructure, and it was not appropriated to subsidize self-storage.
So the baseline rule at federally obligated airports is that hangars serve aeronautical purposes. The FAA reads that category generously:
- Storing an aircraft, whether flyable, in maintenance, or in restoration
- Aircraft maintenance, repair, and modification
- Building an amateur-built or kit aircraft, which the policy expressly recognizes as an aeronautical activity
- Storing aviation equipment, parts, tools, and materials
- Aircraft-related activities that support the above
That third bullet matters more than people expect. Homebuilders spent years being chased out of hangars by nervous airport staff. The 2016 policy settled it: construction of an amateur-built aircraft is aeronautical, and airports are encouraged to accommodate it, though a sponsor may still restrict specific phases like painting in specific buildings for fire and safety reasons.
The non-aeronautical question, answered honestly
The policy does not require a hangar to be empty except for an airplane. It allows incidental non-aeronautical items, furniture, a refrigerator, a workbench, the household overflow that accumulates in every hangar in America, as long as the items do not interfere with the hangar’s primary aeronautical purpose. In practice that means an aircraft still fits, moves, and can be evacuated, and nothing creates a fire or safety hazard.
Where it stops:
- No residences. Living in the hangar is out, full stop.
- No non-aeronautical business operations. Running a landscaping company, a contracting outfit, or a retail inventory operation from a hangar on aeronautical land is not permitted use.
- No inventory or commercial storage for a business unrelated to aviation.
- No long-term storage of derelict aircraft used as a fig leaf to hold cheap square footage.
There is also a financial dimension people miss. If a sponsor does permit non-aeronautical use of airport property, it is generally required to charge fair market rent for that use, because grant assurances obligate the airport to be self-sustaining and to not divert revenue. That is why the rate on a non-aeronautical parcel can be double the aeronautical rate on the ground next to it.
If you want to run a business: minimum standards
Storing your own aircraft is one thing. Selling a service to the public from that hangar is another, and it triggers a different document.
Airports adopt minimum standards, which are the qualifications a business must meet to conduct a commercial aeronautical activity on the field. The FAA’s guidance on this lives in Advisory Circular 150/5190-8, which superseded the long-serving AC 150/5190-7 in December 2023. Minimum standards typically address the type of activity, required leasehold size, building and ramp square footage, hours of operation, staffing and certifications, insurance limits, and fueling arrangements.
Two rules constrain what a sponsor may put in that document. Under Grant Assurance 22, the airport must make the field available on reasonable terms and without unjust discrimination to all types of aeronautical activity. Under Grant Assurance 23, the sponsor may not grant an exclusive right to conduct an aeronautical activity. Together, they mean an airport can set a high bar, as long as the bar is applied evenly and is not designed to protect an incumbent.
That is the leverage point for anyone who has been told “we already have a maintenance shop.” An airport may not lawfully use that as a reason to exclude a qualified second one.
Self-service rights
Owners retain the right to perform certain work on their own aircraft with their own employees and equipment. Servicing, cleaning, minor maintenance, and in many cases self-fueling fall into this category, subject to reasonable safety and environmental rules the airport applies consistently. Sponsors can regulate how you do it. They generally cannot forbid it outright.
What this means when you are shopping
Before you buy or lease a commercial hangar on a public use airport, get three documents in hand: the ground lease, the airport’s minimum standards, and the current airport layout plan showing whether your parcel is designated aeronautical or non-aeronautical. Then match your intended use against all three.
If your business plan needs something the minimum standards do not currently contemplate, that is a conversation with the airport, not a dealbreaker. Sponsors update these documents. But have the conversation before closing, not after.
The takeaway
The FAA framework is more permissive than hangar-row rumor suggests and less permissive than some owners hope. Aeronautical use is broad, incidental storage is allowed, homebuilding is protected, and commercial operators get a fair shot under standards applied evenly to everyone.
