What Is It?

A white woman with orange hair in front of a house next to a smaller accessory dwelling unit.An adult family home is a dwelling, licensed by the Washington State Department of Social and Health Services (DSHS), in which someone provides room and board and care for up to 6 adults not related to the person providing the services. An adult family home that has an existing permitted use as an adult family home may now be expanded to provide services for up to 8 adults. You must have approval from DSHS, in accordance with RCW 70.128.066, to operate an adult family home or to add additional services to an existing permitted adult family home.

Contact DSHS for more information, and to see if you qualify.

What Permits Do You Need?

Please note that even if you are not proposing any construction, you still need to obtain a construction permit to establish the use as an adult family home. Changing the use from a single-family residence to an adult family home will trigger substantial alterations and may require improvements to the building, including seismic upgrades.

Adult family homes are considered a residential use as defined in the Land Use Code per SMC 23.84A.032 and are allowed in most zones. If you want to establish an adult family home, you'll need to meet the standards found in the underlying zone for residential use, (i.e., Single family 5000, LR2, NC2, etc.).

You'll also need a construction permit if you want to provide services for additional adults at an already-permitted and licensed adult family home. For existing permitted adult family homes, care may be expanded from 6 to up to 8 adults with approval from DSHS and if a fire protection sprinkler system is added to the home (RCW 70.128.066).

You will need to obtain a license from DSHS in addition to getting a construction permit. More information on DSHS requirements is available on their website.
