It is not a matter of just adding an amendment to an existing bylaw. the bylaw would have to be re-writting to state that the resort does not have a designated rental operator and owners are allowed to lease their units without a subscription to any operator. The original covenants and restrictions filed with the state of sonora restrict the resort to having only 1 rental company on site (no different than all the other resorts along sandy beach and in most areas). Certain bylaws are restricted to the approval of the undivided ownership regime, such as changing the use of the commercial area (restricted to office space, small general store, restaurant, hotel operations), use of personal property, changing the administrator, removing the requirements for a rental company that adheres to the standards of the resort.
Also, why would this resort do something that no other resort does? Issues I can think of that would occur are problems with security dealing with multiple paying guests, dealing with multiple cleaning companies. I am not sure owners who dont rent would like to see wildcat renting going on in their resort (again, I don't know of a resort that allows your suggestion). Also, how would the HOA collect impact fee's from owners that rent (who would issue wristbands for security to identify they are a guest of the resort, is the HOA now responsible for issuing wristbands to everyone)?, what kind of rating would the resort get when they have hundreds of different owners renting according to their own standards, who would enforce occupancy limits, who would handle maintenance issues for every paying guest if something happens overnight and the owner is not available.
I would love to collect 100% of the rental income, however I know that it would create a mess at the resort. I could just see owners undercutting each other for rentals. For example I have my unit paid free and clear, thus my expenses are low so what would stop me from renting my unit for $75 per night and having it occupied every day of the month. Would owners who have a mortgage benefit from other owners undercutting their rates? I am sure the resort would be filled with love if everyone could do as they please. Unfortunately you bought into a condo regime that limits and restricts what you want to do. No different than an HOA in the states (ex. can't park overnight on the street, can't paint your home as you please, can't leave the garbage out, have to pull weeds, etc.). My suggestion is if an owner would want to do as they please with no restrictions is to purchase a home that is not governed by an hoa.
