Arapahoe County, CO Home Business: Signage Rules (2026)

Unlike commercial properties, which can apply for signage under the county's general sign standards in Chapter 4, a home occupation operating out of a residence in unincorporated Arapahoe County isn't allowed any visible advertising on the property at all. Section 3-3.12.A.2's Requirements and Restrictions list states plainly that the home occupation must be conducted only by residents of the dwelling and that 'there shall be no visible advertising of the home occupation on the premises upon which it is located,' immediately paired with a matching ban on outdoor storage of goods or materials tied to the business.

The intent, stated at the top of Section 3-3.12.A, is to let a residence be used for an occupation 'which does not change the character of the neighborhood in which it is located': a yard sign, window sign, or vehicle wrap advertising the business from the property would defeat that purpose. The prohibition applies on top of the code's broader requirement that a home occupation not change the appearance or character of the dwelling, and it sits alongside a parallel, sector-specific signage ban for home-based day cares, which the code separately says 'shall not be allowed signage' under Section 3-3.12.B.
