Washington Revised Code Title 36. Counties § 36.70A.450. Family day-care provider's home facility--County or city may not prohibit in residential or commercial area--Conditions

(1) Except as provided in subsections (2) and (3) of this section, no county or city may enact, enforce, or maintain an ordinance, development regulation, zoning regulation, or official control, policy, or administrative practice that prohibits the use of a residential dwelling, located in an area zoned for residential or commercial use, as a family day-care provider's home facility.

(2) A county or city may require that the facility: (a) Comply with all building, fire, safety, health code, and business licensing requirements; (b) conform to lot size, building size, setbacks, and lot coverage standards applicable to the zoning district except if the structure is a legal nonconforming structure; (c) is certified by the department of children, youth, and families licensor as providing a safe passenger loading area; (d) include signage, if any, that conforms to applicable regulations; and (e) limit hours of operations to facilitate neighborhood compatibility, while also providing appropriate opportunity for persons who use family day-care and who work a nonstandard work shift.

(3) A county or city may also require that the family day-care provider, before state licensing, require proof of written notification by the provider that the immediately adjoining property owners have been informed of the intent to locate and maintain such a facility. If a dispute arises between neighbors and the family day-care provider over licensing requirements, the licensor may provide a forum to resolve the dispute.

(4) Nothing in this section shall be construed to prohibit a county or city from imposing zoning conditions on the establishment and maintenance of a family day-care provider's home in an area zoned for residential or commercial use, so long as such conditions are no more restrictive than conditions imposed on other residential dwellings in the same zone and the establishment of such facilities is not precluded. As used in this section, “family day-care provider” is as defined in RCW 43.216.010.
