Boulder County's Land Use Code (Article 13) does not exempt garage-sale signs generally; temporary signs must meet the zoning district's size and setback rules and may never be placed in a public street, road, or highway right-of-way.

This Article does not apply to the following: Signs not visible from off-premises or a public right of way. Signs must not be placed in the right of way of any public street, road or highway, except as specifically provided for in the sign code.
Full Breakdown
Article 13 regulates the number, type, location, dimensions, and design of signs in unincorporated Boulder County. It provides a specific exemption only for signs 'not visible from off-premises or a public right of way,' so a garage-sale sign on your own property that is not visible from the road is not regulated. A temporary sign placed at the street to advertise a sale is a regulated sign that must meet the district's area and setback limits and must not be placed in the right-of-way of any public street, road, or highway.
Violations & Fines
Off-premises or right-of-way garage-sale signs may be removed by the county without notice; repeat violations are enforced under Article 13 and Article 4-1300 with removal orders and possible fines.
