Denver does not require a permit for residential garage sales. Sales are allowed at private residences subject to frequency, time, and signage rules under DRMC Chapter 32 and the zoning code. Signs in the public right-of-way are prohibited without a permit.
Denver is relatively permissive on garage and yard sales: no permit or registration is required for residential garage sales at a personal residence. However, such sales are subject to several DRMC rules. Under DRMC Chapter 32 (Peddlers/Merchants), sales must be 'casual,' involving personal household property only — selling goods purchased for resale triggers a peddler license requirement. Sales are restricted by frequency and duration (see frequency-limits subcategory). Signs advertising sales must not be posted in the public right-of-way (street medians, ROW poles, traffic signs) — doing so violates DRMC §49-248 (signs on public property) and §10-20 (nuisance signs) with $50+ per sign citations. Signs on private property are allowed only during the sale and 24 hours before/after. Homeowners selling as a home-based business must meet zoning home occupation rules. HOAs in Denver (Stapleton/Central Park, Green Valley Ranch) frequently impose additional garage-sale restrictions.
Signs in ROW: $50 to $200 per sign DRMC §49-248, city removes without notice. Selling as unlicensed peddler: $100 to $999 DRMC Chapter 32. Frequency/duration violations: code enforcement notice.
