I don’t believe the advise is wrong. The EC can grant permission for residents to park on the common property by just a simple majourity. The default bylaws state as much. The resident would not have exclusive use of the area just be able to use it, and permission could be removed at any time by another simple majourity vote. If the EC is enforceing the bylaws this would be sufficient.
You would be correct scotlandx IF the resident wanted exclusive use but if the resident just wanted somewhere to park just a simple vote is sufficient.
Exclusive use would be for ever and not eaisly removed and would pass on to future owners of said lot which might not require it. It would also increase the value of this lot and reduce the amount of common property which might be a bad thing.
