Contracts like you suggest are common and working today in other cities. When I bought a condo in central London, my contract with the association of all other owners in the building specifically forbade short-term sublets, and forbade any sublets without the written approval of the association. When one condo owner started renting out on weekends through web advertising, the association had its lawyer bring that clause to the owner's attention and the practice was stopped immediately. No law needed. (BTW, these contracts for UK condo property take the form of "leases" for hundreds of years, which can be sold like other property.)
