Provincial starting point
Province-administered ADU route in unplanned areas
P.E.I.: a provincial ADU route applies in areas without local plans and bylaws.
PEI defines an accessory dwelling unit as an independent secondary unit on the same parcel as an existing single-family home. It may be separate, attached to or within an accessory building, or an in-law suite. The 2024 regulation changes allow these units for long-term housing.
The provincial changes apply outside municipalities with an official plan and bylaws. Development and building permits are required; building-code, fire-marshal and, where relevant, highway-access requirements also apply. In municipalities that administer their own planning, use the local rules instead.
Provincial framework reviewed September 20, 2026. First determine whether the property is in a municipality with its own official plan and bylaws.
