Gaithersburg, MD Sign Regulations: Garage Sale Signs (2026)

Gaithersburg's sign regulations govern temporary signs including those advertising garage sales and yard sales. Signs placed on the property where the sale is held are generally permitted without a sign permit during the sale period. The city limits the number and size of temporary signs per residential property. Signs placed off the sale property on other private property require that owner's permission. Placement in the public right-of-way, on utility poles, street signs, traffic signals, median strips, or city property is prohibited. Signs that obstruct motorist or pedestrian visibility at intersections or driveways are removed immediately for safety. The city's code enforcement officers actively remove signs placed illegally in the right-of-way during regular patrols. All garage sale signs must be removed within 24 hours after the sale concludes. Signs left beyond this period are subject to code enforcement action. Directional signs guiding buyers to the sale location are common but must follow the same placement rules.
