Currently, Vancouver's city planning department treats covered balconies or patios in single-family homes as part of the inside of a house.
So if a home is already at its limit for square footage, residents are not allowed to install a cover.
City Councillor Tony Tang says the rule does not make sense in Vancouver's wet climate.
"If you run into foul weather, then all your plans will be ruined," said Tang, who will put forward a motion to city council on Wednesday, asking staff to review the bylaw.
But former city councillor Gordon Price says the bylaw exists because builders who want to get the most out of a lot will convert balconies into an extra room.
"Just know that there's going to be that kind of complication, because it's certainly been the story in the past," warned Price.
Tang says that concern should not stop people from getting the most from their outdoor space, and says any abuse of the rules can be dealt with by city enforcement officers.
