Summary

Redwood City lets residents post garage sale signs on the sale day without a permit, but City Code Section 3.81 caps each sign at four square feet and three feet in height, and limits any one property to four signs per sale.

Garage sale signs may be displayed on properties where the garage sale is occurring on the day that such sale is held. Each garage sale sign shall comply with the following requirements: maximum size of any one sign: four (4) square feet (measured one side only); maximum height: three feet (3′) in height above grade; maximum of four (4) signs per property per garage sale. Garage sale signs displayed on public property within the City are subject to the provisions of Section 3.153, Division 6, Article III, Signs on Public Property.

Full Breakdown

81 of the Redwood City Code governs garage sale signs on private property. A sign may go up only on the day the sale is actually held, so signs posted days in advance or left up afterward fall outside the exemption. Each sign is capped at four square feet, measured one side only, and three feet in height above grade, and a single property may display no more than four such signs per sale. 153, which permit signs only from sunrise to sunset on Saturdays, Sundays, and legal holidays, cap them at six square feet and three feet in height, limit displays to four per event, and bar placement in a street median or anywhere blocking a driveway visibility triangle.

71 backs both provisions with a general enforcement rule: any prohibited or noncompliant sign is subject to immediate abatement by the property owner or whoever installed it once the City gives notice. 61, homeowners never need to apply to the Planning Division before a one-time garage sale, so long as they stay within these size, timing, and quantity limits.

Violations & Fines

A garage sale sign left up before or after the sale day, or one exceeding four square feet or three feet in height, loses its exemption and can be ordered abated under Section 3.71 once the City gives notice to the property owner or installer. Signs placed on public property outside Section 3.153's Saturday-Sunday-holiday, sunrise-to-sunset window are summarily removable by the City.

Frequently Asked Questions

How many garage sale signs can I put up in Redwood City?
Up to four signs per property for each garage sale, under City Code Section 3.81. Each sign can be no larger than four square feet measured on one side and no taller than three feet above grade, and all of them may be displayed only on the day the sale is held.
Can I post garage sale signs on the street or sidewalk?
Only under the separate public-property rules in Section 3.153, which restrict such signs to sunrise-to-sunset display on Saturdays, Sundays, and legal holidays, cap them at six square feet and three feet in height, and forbid placing them in a street median or blocking traffic visibility.
Do I need a permit for a garage sale sign?
No. Garage sale signs are exempt from Redwood City's standard sign permit process as long as they meet Section 3.81's size, height, and one-day display limits. A sign that stays up longer or exceeds those limits loses the exemption and can be ordered removed.
