District of Columbia, DC Garage & Yard Sales: Frequency Limits (2026)

DC's yard sale regulation is pragmatically rather than numerically enforced. There is no ordinance stating 'no more than N sales per year,' but three overlapping legal constraints effectively limit frequency. First, DC Code 47-2851.03 (Basic Business Licensing) requires a business license for any 'commercial activity' conducted for profit, including sale of merchandise acquired for resale. If a resident holds frequent sales that include items purchased at auction, thrift stores, or in bulk for resale, DLCP can classify the activity as an unlicensed second-hand dealership, merchant, or flea market operation. Second, 11 DCMR Subtitle U section 302 (Home Occupation) requires a Home Occupation Permit for regular business activity conducted from a residence, with strict limits on customer traffic, signage, and external impacts. Ongoing yard sales that generate street parking complaints or neighborhood traffic can trigger zoning enforcement. Third, the informal neighborhood standard — enforced via ANC complaints and 311 reports — is typically 2-4 sales per year. Neighborhood-wide sales (HOA or ANC-organized multi-block events) are treated as single events. Estate sales are generally unrestricted but should not operate as ongoing retail.
