My 32-unit condo complex in Minnesota has an extra eight garage stalls to rent out. Recently the board has rented some of them to non-residents which is against the bylaws. The garage stalls have dividing walls but are open across the top, so this presents a security issue. We are not licensed by the city as a public storage facility, nor will the city get involved. I would rather the garage stalls be empty until an owner or resident wants one. How can we prevent the board from renting garage stalls to the public?
