Rockville, MD Property Maintenance: Garage Sale Rules (2026)

Under the City of Rockville Code, residential garage, yard, and tag sales are permitted in all residential zones without a special permit, but are limited to three sales per household per calendar year. Each sale may last a maximum of three consecutive days. Sales must take place on the property and items may not be displayed in the public right-of-way, on sidewalks, or in a manner that obstructs pedestrian or vehicular access. Signage advertising garage sales is limited to the property where the sale occurs and one directional sign at the nearest intersection, which must not be attached to utility poles, street signs, or traffic control devices. All signs must be removed within 24 hours of the sale ending. Montgomery County also regulates garage sales under Chapter 30 of the County Code for unincorporated areas, but Rockville's municipal code governs within city limits. Many HOA-governed communities in Rockville impose additional restrictions including requiring advance board notification, limiting sale hours, and mandating cleanup timelines. Residents should check their HOA covenants before holding a sale. Contact Rockville Code Enforcement at 240-314-8530 for questions about residential sale regulations.
