We have an existing (specific) by-law about external awnings which specifies the company used/ brand, style and type of awning and the mesh colour. Some owners chose to purchase the awnings, and others chose not to. Each awning is classed as owner property and maintenance is the responsibility of the owner. It is now out of date as the type of awning is old, but we will pursue the same thing when the need arises and the awnings start needing replacement. It works well because it is clear for everyone what is (and isn’t) permitted and it keeps a uniform look around the complex.
