Littleton, CO Home Business: Signage Rules (2026)

10 of the Unified Land Use Code, and the code's signage rule is written broadly rather than as a size or number limit: subsection f prohibits any outdoor display or storage of goods, materials, merchandise, equipment, or signage related to the home occupation that is visible from the exterior of the principal dwelling. That means a home business in Littleton effectively cannot post a yard sign, window sign, or any exterior-visible signage advertising the business at all, not merely one that exceeds a size threshold.

The following subsection reinforces the same policy from the building side: no alteration shall be made to the principal dwelling that changes its residential character, nor shall there be any outward appearance of a home occupation. Together the two provisions mean the home has to look and read as an ordinary residence from the street, with the business invisible from outside. This is stricter than the sign standards written for freestanding commercial signage elsewhere in the Unified Land Use Code, and it exists because home occupations are approved as accessory to residential use, not as a commercial use of the property; the code's overall home occupation package repeatedly ties approval to the dwelling retaining its residential character, including limiting operation to indoor space and capping combined home-business floor area at 20 percent of the dwelling and accessory structures.
