I reduced my 3000sf hangar floor space by quickly adding a workshop and some closets (built with nonstructural walls) in the back of mine. Once you're down in the "residential" category, you really don't have any different construction requirements than those for your car garage (1 hour fire wall...typically a double layer of drywall...if it adjoins living space).A residential hangar is actually less restricted than an accessory building. There are special requirements when you build accessory buildings near the edge of your property that don't apply to the residential hangar.
