Residential / Accessory Dwellings
primary dwelling
accessory dwelling

An accessory dwelling unit is a second dwelling unit on the same piece of property as the primary dwelling unit.

A dwelling unit is defined as a single structure providing complete independent facilities for one or more persons, including permanent provisions and fixtures for living, sleeping, eating and sanitation.

Accessory dwelling units are not allowed in all zones, and can be limited in size. Planners are available at PDS to advise you on the various zoning and permitting requirements for an accessory dwelling.

The submittal process for obtaining a building permit for an accessory dwelling is the same as for a single-family residence.
