Summary

Home occupations in unincorporated Arapahoe County get no signage at all. LDC § 3-3.12.A.2 flatly requires that there 'shall be no visible advertising of the home occupation on the premises upon which it is located,' on top of a ban on any outdoor storage tied to the business.

City-specific rules exist: Centennial has its own signage rules rules that differ from Arapahoe County's county-level regulations. If you live in Centennial, check the city-specific page instead.

The home occupation shall be conducted only by the residents of the principal dwelling. There shall be no visible advertising of the home occupation on the premises upon which it is located. There shall be no outdoor storage of goods or materials associated with the home occupation.

Full Breakdown

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. 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.

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. B.

Violations & Fines

A visible sign, banner, or other advertising placed at a home occupation property fails Section 3-3.12.A.2 outright and is treated as a home-occupation compliance violation. The Planning Division can require the resident to take the signage down; continued visible advertising puts the property's eligibility to operate the home occupation itself at risk under the same section's neighborhood-compatibility standard.

Frequently Asked Questions

Can I put a small sign in my yard advertising my home business in unincorporated Arapahoe County?
No. LDC § 3-3.12.A.2 requires that 'there shall be no visible advertising of the home occupation on the premises upon which it is located,' with no size or type exception for small signs.
Does the no-signage rule apply to vehicle wraps or window signs too?
The code's language covers 'visible advertising ... on the premises,' which reaches any sign, banner, or advertising display visible on the property, not just freestanding yard signs; a vehicle advertising the business parked and displayed on-site would fall under the same prohibition.
Are home day cares also barred from having signs?
Yes, separately. Section 3-3.12.B says a 'day care home' shall not be allowed signage, mirroring the general home-occupation ban but stated as its own requirement for licensed day care homes.
