Denver does not impose a specific numerical limit on the number of garage sales a resident may hold per year. However, sales that become regular or frequent enough to constitute a commercial retail operation may be treated as a home business subject to zoning and licensing requirements.
The DRMC does not specify a maximum number of garage sales per year for residential properties. The distinction between occasional garage sales and a home-based retail business is based on frequency, duration, and character of the sales. Weekly or near-weekly sales would likely trigger home occupation classification. Seasonal sales (spring cleaning, holiday sales) held a few times per year are clearly within the occasional use standard. Denver zoning enforcement uses a reasonableness standard — multiple complaints about frequent sales may trigger investigation. Estate sales and moving sales are considered one-time events regardless of duration.
Operating what is effectively a retail business under the guise of frequent garage sales can result in zoning violations (operating a business in a residential zone without home occupation approval) and business licensing violations. Enforcement is typically complaint-driven through Denver 311.
