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

The Gaithersburg Code of Ordinances allows residential property owners and tenants to hold garage sales, yard sales, and estate sales without obtaining a business license or special permit. Sales are considered accessory to the residential use and must be conducted on the property where the seller resides. The city limits the number of sales to avoid creating a de facto retail operation, generally allowing a reasonable number per year. Items for sale must be personal property of the residents, not purchased inventory for resale. Signs advertising the sale must comply with Chapter 24 (Signs) of the city code. Signs placed in the public right-of-way or on utility poles are prohibited and subject to removal. HOA-governed communities including Kentlands, Lakelands, and Washingtonian may restrict the frequency, duration, or signage of garage sales through their covenants, conditions, and restrictions (CC&Rs) under Maryland Real Property Title 11B. Many HOAs organize annual community-wide yard sales as an alternative. Contact the city at 301-258-6300 for general questions.
