…The main issue is the delivery trucks that deliver to her garage. There are weekly deliveries to her garage which is underground, and the trucks often block access to the other garages. We’re also concerned about the extra wear and tear on the driveway…
These days lots of people have a home office and could run a business with just a computer and little else. Such a business could be entirely invisible to the neighbours and cause no problems whatsoever. It seems unreasonable to me to prohibit that.
On the other hand, perhaps you can address trucks and blocking of access purely from the point of view of the usual general purpose rule/by-law/article that most have that prohibits unreasonable interference with reasonable use and enjoyment of the common property by other residents.
