Centennial, CO Sign Regulations: Garage Sale Signs (2026)

Section 12-6-501(A) says that any freestanding temporary sign type not listed in Table 12-6-501A or Table 12-6-501B is not permitted, so a sale sign has to qualify as one of the listed types. The code defines a yard sign as a temporary sign of paper, vinyl, plastic, wood, metal or comparable material, mounted on a stake or wire frame and designed for short display, which describes the stake-mounted sign most sellers put out.

In the AG, RS, RA, RU, NC and NI districts, Table 12-6-501A allows yard signs with no maximum count, provided the size and height limits are met. Each sign is capped at 6 square feet. The table prints total-area caps of 36 and 24 square feet and height caps of 5 feet and 4 feet. Under § 12-6-501(B), every temporary sign sits at least five feet from all property lines, unless the corridor rules of § 12-6-502 push it back further. A sign that cannot be seen from a public right-of-way or from abutting property is not restricted by § 12-6-501 at all.

Nonresidential land is far tighter. Table 12-6-501B bars yard signs in the CG, AC, UC, EC-MU, EC-N, EC-LI, BP and I districts and allows them only in the ED and OSR districts, at 2 per ingress or egress, 6 square feet each and 4 feet tall. Sidewalk signs are not allowed in any of the six agricultural and residential districts.

Location is where sale signs fail. Section 12-6-302(D)(1) bars any sign in or over a public right-of-way, which the code defines to include sidewalks, parkways, medians, utility poles and traffic control devices. Section 12-6-302(C) bars signs mounted on trees, utility poles and light poles, with a narrow exception for small banners, and § 12-6-302(B) bars any sign that blocks a sight triangle. Along 33 named corridors, including S. Havana Street, E. Arapahoe Road and S. Parker Road, § 12-6-502(B) keeps temporary signs out of the right-of-way and at least 30 feet from the edge of pavement, except where the front yard of a single-family lot abuts the corridor. How long a sign can stay up depends on its material and is set in § 12-6-504.
