Pittsburg, CA Sign Regulations: Garage Sale Signs (2026)

Garage sale directional signs are treated under Pittsburg's temporary sign provisions in the zoning code. Each garage sale may have one small sign on the property where the sale is being held plus off-site directional signs, each typically limited to about 4 square feet. Off-site signs must be placed entirely on private property with the express permission of that property owner - not in parkways, medians, or utility easements. Attaching signs to utility poles, streetlights, stop signs, street-name signs, trees in the public right-of-way, or traffic control devices is prohibited under both the Pittsburg Municipal Code and California Vehicle Code §21465 (which bars placement of unauthorized signs that resemble or interfere with traffic signals). Signs may only be displayed during the sale itself - typically posted the morning the sale begins and removed immediately when the sale ends on the same day or at the end of the sale weekend. Leaving signs up past the sale is a code enforcement violation and considered litter/abandoned sign subject to removal and possible citation. Signs should not exceed about 4 feet in height and must not obstruct sight distance at intersections or driveways. Pittsburg residents generally do not need a permit to hold a garage sale, but are limited to a small number per year (commonly 2-4) as described in the garage sale frequency rules. Report abandoned signs to Code Enforcement.
