Mason County, WA Sign Regulations: Political Signs (2026)

Mason County treats political signage as a category of temporary sign, not a separate permit track. The Allyn UGA sign code's definition section, § 17.15.040, defines a political sign as any temporary sign advertising a candidate, a political party, or urging a vote on a ballot measure. The operative rule sits in § 17.15.080(3), 'Signs displayed during elections and campaigns': permitted location is private property with the owner's consent, or the public right-of-way if it meets the county's separate right-of-way sign standard in § 17.03.202(C) and (D), plus state law; duration is capped at ten days after the final campaign or election.

The Belfair UGA carries an identical rule at § 17.34.080.C, and rural areas and the Shelton UGA fall under the general temporary-sign rule at § 17.05.025, which requires removal within ten days of the event or activity ending and bars placement in the right-of-way without a public works road-use permit and the adjacent owner's permission. Right-of-way signs elsewhere in the county are additionally capped at four square feet under § 17.03.202(C)(5) and cannot block sight lines at intersections, driveways, or access points. None of these sections require a sign permit or fee for a political sign; the county's authority is limited to size, placement, and the post-election removal deadline. Community Development, which administers Title 17, and the public works department, which issues road-use permits for right-of-way placement, share responsibility for handling complaints.
