Summary
Unincorporated King County lets any occupant bar door-to-door solicitors just by posting a sign. Under King County Code § 12.66.010, once a "No Solicitation" or "No Trespassing" sign sits at or near the entrance, an uninvited person may not enter or remain on the premises to pitch a sale, and the sheriff enforces the ban as a civil infraction.
12.66.010 Solicitation prohibited if sign posted. If a person has not been requested or invited by the occupant, the person shall not enter or remain upon any private premises for the purpose of contacting the occupant to solicit the immediate or future purchase or sale of goods, services or any other thing of value if a sign stating "No Solicitation" or "No Trespassing" is posted at or near the entrance to the premises.
Full Breakdown
090. C. 80 RCW, the state's civil infraction statute, rather than a criminal charge, which keeps sign violations out of criminal court while still allowing a fine.
Violations & Fines
Ignoring a posted "No Solicitation" or "No Trespassing" sign to pitch a sale is a class 2 civil infraction under § 12.66.040, punishable under chapter 7.80 RCW, and it is enforced by King County Sheriff's deputies rather than charged as a crime. A citation can issue on each entry onto posted property, and the sheriff may use the broader code-enforcement authority in K.C.C. Title 23 alongside chapter 7.80 RCW when addressing repeat solicitors. Exempt solicitors under § 12.66.020, charities, political and religious groups, government agencies, and farmers under RCW 36.71.090, face no penalty for approaching a signed door.
