Accessory Dwellings

An accessory dwelling unit is a 2nd 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 1 or more persons, including permanent provisions and fixtures for living, sleeping, eating, and sanitation.

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

Zone Regulations
Accessory dwelling units are not allowed in all zones, and can be limited in size. Planners are available at Planning and Development Services to advise you on the various zoning and permitting requirements for an accessory dwelling. If you need assistance, call 360-676-6907.
