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

04(D), which requires a home occupation to remain subordinate to the home's principal use and mandates Site Plan Review before operation. Table 6-4, "Summary of Home Occupation Regulations," sets the sign allowance at 2 square feet maximum, and unlike several other standards in the same table that split by Rural versus Urban Residential district, the sign cap applies uniformly across both. The table pairs that limit with a companion rule under "Exterior Appearance": no change may make the dwelling look less residential from the road or from adjoining properties, and the occupation itself must stay entirely inside a permitted principal or accessory building.

A resident operator must live in the dwelling full time. 04(D)(2) exempts very small home businesses, those drawing 10 or fewer client visits a week, hiring no nonresident employees, and running no outdoor activity or hazardous-material storage, from the full home occupation review, but the 2-square-foot sign figure in Table 6-4 still governs any signage a home business posts. Anything larger goes through Site Plan Review with the Mesa County Community Development Department, which checks the application against Table 6-4 before issuing approval.
