Summary
A home occupation in unincorporated Doña Ana County may display exactly one sign, capped at one square foot and nonilluminated, under UDC § 350-510F. It must be freestanding or mounted flush to the dwelling and can only reference the home occupation itself, with no other outward evidence of the business permitted.
Only one sign, one square foot in size, nonilluminated, freestanding or mounted flush against the residential dwelling, shall be permitted which refers to the home occupation.
Full Breakdown
' Read together, the two subsections mean a permitted home business can identify itself with one small, unlit sign and nothing else: no illuminated signage, no second sign for a second service line, no banners, and no window displays visible from the street. The sign requirement is folded into the home occupation permit review itself; § 350-510N(2) requires an applicant's site plan to show 'proposed signage' as part of the CDD's review, so a business that wants the one-square-foot sign must disclose it up front rather than add it after approval.
Because this sits inside the home occupation chapter, it binds only unincorporated Doña Ana County; Las Cruces, Sunland Park, Mesilla and Hatch set their own home-business sign rules.
Violations & Fines
An oversized, illuminated, or additional sign is a home occupation violation under § 350-510, subject to the same certified-mail notice and revocation process as any other permit violation (§ 350-510O); the County can revoke the home occupation permit and refer the case for prosecution in Magistrate or District Court once notice and a cure period have passed.
