Costa Mesa's Garage & Yard Sales: The Rules That Matter

If you live in Costa Mesa or are thinking about moving there, garage & yard sales are one of those things you probably won't think about until they affect you directly. Costa Mesa has 3 specific rules on the books covering different aspects of garage & yard sales, and some of them might surprise you.

Frequency Limits

Costa Mesa does not impose a strict numerical limit on the number of garage sales a resident may hold per year. However, sales conducted frequently enough to resemble commercial activity — such as weekly or biweekly sales, or sales of new or purchased-for-resale merchandise — may be classified as a home business requiring a business license and compliance with home occupation permit requirements.

Key details: Formal Limit: No strict number set in code. Commercial Threshold: Frequent sales may require business license. Resale Goods: Selling purchased-for-resale items is commercial. Estate Sales: Generally treated as single events.

Operating a commercial retail business under the guise of a garage sale without a business license is a violation of the Municipal Code. Code Enforcement issues a notice of violation requiring the activity to cease or the operator to obtain proper business licensing. Administrative citations start at $100 and escalate for repeated violations. Continued commercial activity without licensing may result in criminal misdemeanor charges.

The rules around frequency limits in Costa Mesa lean permissive, but that does not mean anything goes.

Garage Sale Permits

Costa Mesa does not require a permit for residential garage sales, yard sales, or estate sales conducted at the seller's own residence. Sales must be held on the property and may not spill onto sidewalks, parkways, or public streets. Signs advertising the sale are subject to the city's temporary sign regulations and must be removed immediately after the sale concludes.

Key details: Permit Required: No — residential garage sales exempt. Location: On property only, not on sidewalks or streets. Signs: Must follow sign ordinance, remove after sale. Commercial Sales: Require a business license.

While garage sales themselves do not require permits, violations of related ordinances may result in enforcement action. Illegal sign placement carries fines starting at $100. Sales that create nuisance conditions or traffic hazards may result in a code enforcement notice requiring the sale to be shut down. Operating a commercial enterprise disguised as a garage sale without a business license is a violation of the Municipal Code.

Costa Mesa is more permissive than most cities when it comes to garage sale permits. That said, there are still limits.

Time Restrictions

Costa Mesa garage sales should operate during reasonable daylight hours, typically between 8:00 AM and 6:00 PM. While the Municipal Code does not specify exact garage sale hours, sales conducted early in the morning or after dark may generate noise and traffic complaints subject to the city's noise ordinance and nuisance provisions. Multi-day sales should be limited to weekend periods.

Key details: Recommended Hours: 8:00 AM – 6:00 PM. Multi-Day Sales: Best limited to Friday–Sunday. Overnight Items: Should be stored inside after each day. Noise Ordinance: Applies to early/late sale activity.

Garage sales operating outside reasonable hours that generate noise or nuisance complaints may result in Code Enforcement action. Officers may direct the sale to cease for the day if it is creating disturbances. Noise ordinance violations between 10:00 PM and 7:00 AM carry administrative citations starting at $100. Items left outside overnight between sale days may result in a property maintenance notice.

If you are coming from a city with tighter rules, you will find Costa Mesa gives residents more flexibility on time restrictions.

The Bottom Line

Compared to many U.S. cities, Costa Mesa gives residents more room on garage & yard sales. 3 of the 3 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

Keep in mind that Costa Mesa can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
