Newark, DE Garage & Yard Sales: Frequency Limits (2026)

New Castle County does not publish a specific frequency limit (e.g., X sales per year) for garage and yard sales in unincorporated areas. Instead, the UDC Article 40 treats excessive or commercial-scale sales as a potential zoning violation under home occupation or unauthorized retail provisions. As a practical matter, homeowners holding 2 to 4 sales per year of reasonable duration are not considered in violation. Sales operating continuously, advertising as a store, or selling commercially purchased merchandise cross into unlicensed retail territory and can trigger enforcement. The City of Wilmington Code and City of Newark Code explicitly limit sales, commonly to 2 to 4 per calendar year with each event lasting no more than 2 to 3 consecutive days. Exceeding city limits can trigger citations. Homeowner Association covenants in Hockessin, Pike Creek, Greenville, Brandywine Hundred, and Middletown-area subdivisions commonly limit sales to 2 per year and restrict signage; these are enforced by HOAs through fines and, in extreme cases, civil action. Neighborhood-wide or church-sponsored sales are generally treated as a single event under any applicable limits. Estate sales conducted by licensed estate sale companies have different rules and may require a separate business license.
