In our Strata our EC has told the owners to look at enforcing bylaws as if they are nuisances. And how big a nuisance a breach causes is used as a guide to how strictly it will be enforced.
As an example, we have an issue about the standard bylaw about vehicles parking on common property. Because of the physical layout of our units we have a few owners who can park on common property (directly outside their garage). Them doing so does not cause any problems to anyone else (except access to their own garage). However we have a few units where parking outside their garage (on common property) is a distaster and blocks other owners from accessing their garages.
One of the owners that can’t park outside their garage wanted a strict enforcement of the ‘no parking on common property’ bylaw. This owner’s only argument was that “if I can’t do it no one should be able to”. The EC told the owner while they would enforce the bylaw against him, they would not enforce it against owners who can do so without a nuisance to anyone else.
