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

Solano County's sign regulations in Chapter 28 (Section 28.96) govern signs in unincorporated areas but do not include a dedicated provision for garage sale or yard sale signs. The temporary-sign provisions in Section 28.96.70(D) specifically address construction signs, campaign signs, and real estate signs - not garage-sale signs. As a baseline, Section 28.96.40 lists prohibited signs, which include off-premises signs (except narrow listed exceptions), and the code states no sign is permitted within a public right-of-way. That means the common practice of stapling garage-sale signs to utility poles, fences, or placing them on road shoulders and medians is not authorized under the code. A temporary garage-sale sign placed on your own private property, kept small and not illuminated, is the lowest-risk approach, but because there is no on-point provision, residents should confirm with the Planning Division (707-784-6765) what is allowed for a short-duration sale. Off-premise directional signs are tightly limited (for example, certain real estate directional signs up to six square feet on private property with consent) and do not create a general garage-sale exemption. When in doubt, keep signs on your own property and remove them promptly after the sale.
