I've been renting the same hangar for the past 10 or 15 years from a private individual on City owned airport property. This month, the City bought our hangar, and now will be leasing hangar space to us. I know how it works with residential rental property, but am not clear about how access to a City owned hangar works. They are now requiring that we give them keys to our hangar. Do City personnel have the right to enter your hangar any time without your permission?
