Re: Sounds like
I haven't seen restrictions for the number of garage parking spaces on a lot, but I have seen regulations addressing "snout houses" (houses with dominant projecting front-loading garages) and the overall garage width along the facade.
Another possible reason to restrict the number of residential garage spaces is to prevent the possibility of illegal automotive-based home occupations.
Lima doesn't strike me as a particularly progressive community, for some reason, so reducing automotive dependence probably isn't a factor. I live alone in a house with a two car garage, but that extra space doesn't mean I'm going to drive more.
Canadian zoning regulations usually don't have anti-snout house provisions, because land in urban areas is much more expensive than in the States, and per-capita automobile ownership is only a wee bit lower. No alleys (gotta' keep 'em plowed, which costs money), narrow lots, and lots of cars in a family; if there were no snout houses, there'd be no parking.
