Generally, garages are allowed on a lot only if the principal structure(house) is present or under construction.
Garages are limited in size by both the zoning district and lot size. Both attached garages and detached garages combined are considered when determining the square footage allowed for the lot.
In a few instances, a garage lot may be across the road from residential lake lot where there is not enough room on the lake lot for a garage and a house. See "Garage Lots" on our website.
