California Yard Sale Permit & Sign Rules (2025 Guide)

California yard sale permit — this 2025 guide explains when a California yard sale permit is required, how city/county rules differ, and what’s legal for signs so you stay compliant and attract more buyers.

Do I need a California yard sale permit?

State tax rules (CDTFA): Casual garage/yard sales of your own used items generally do not require a seller’s permit. If you hold more than two sales within 12 months, you may be considered a temporary seller and need a permit. See:
CDTFA — Temporary Sellers.

Local city/county rules: Beyond CDTFA, your city or county can require registration or limit weekends/hours/signage. Always check your local code before advertising your sale; some jurisdictions explicitly name a “California yard sale permit” or local registration.

Where can I post yard sale signs in California?

Consent is required: Under California Penal Code §556 et seq., placing signs without the property owner’s permission can be unlawful. Poles, traffic signs, and public fixtures are generally off-limits unless your jurisdiction explicitly allows it under strict rules.

Example (county guideline): Some counties limit yard-sale signs to your own property and cap sign area. See:
Sacramento County — Yard Sales & Concessions.

California yard sale permit & signs: quick compliance checklist

• Identify your city vs. county jurisdiction (rules differ).
• If holding more than two sales/year, review CDTFA’s temporary seller rules and obtain any required California yard sale permit.
• Post signs only with owner permission; avoid utility poles, traffic signs, and public fixtures.
• Use large arrows and minimal text; remove signs promptly after the sale.
• Check HOA rules if you live in a managed community.
