Accessory Apartment Bylaws and Ordinances
An Accessory Apartment Use bylaw is a zoning regulation that allows an additional dwelling unit on a
parcel beyond what is otherwise allowed in that zone. The additional dwelling unit can be within the main house or in a detached pre-existing outbuilding or secondary structure such as a barn, garage or carriage house. An Accessory Apartment Use bylaw promotes preservation in residential settings by allowing more intensive use of outbuildings or large dwellings that may be threatened with demolition or lack of maintenance. Such a bylaw may encourage reinvestment through rehabilitation of important historic resources in residential neighborhoods as well as providing additional housing opportunities.
