Salt Lake County, UT Home Business: Signage Rules (2026)

The no-signage rule is a defining feature of home occupation regulation and is strictly enforced. Under Salt Lake County ordinance, a home occupation may not include any exterior indication of the business, including but not limited to wall signs, yard signs, window signs visible from outside, illuminated displays, flags, banners, or decorative signage. This rule applies regardless of sign size. The rationale is to preserve residential character and prevent the home from appearing commercial. The only typical exception is a single small nameplate (often limited to 1 square foot) identifying the resident practitioner where required by state professional licensing (for example, some state boards require the licensee name posted). Vehicle signage on personal or business vehicles parked at the home is generally allowed if the vehicle is under 1 ton and registered to the resident; large commercial vehicles (box trucks, trailers over a specified size) cannot be stored on residential property as part of a home occupation. A-frame or sandwich board signs in the public right-of-way are prohibited county-wide. Violations are enforced through code enforcement with notice and cure, escalating to daily fines. HOAs may impose even stricter signage rules, including blanket bans.
