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

The sign rule is written as a ceiling, not a menu. The code allows only a three square foot, non-illuminated nameplate sign, and it must be attached to a wall or window of the dwelling itself. That mounting requirement rules out freestanding signs, yard signs, and anything posted away from the house: if it is not on a wall or in a window of the home, it does not comply regardless of its size. Lighting of any kind is off the table, because the nameplate must be non-illuminated.

The surrounding home business standards in the same section shape how the operation can look from the street. Subsection M prohibits bringing, parking, or storing any vehicle larger than a passenger car, van, or one ton pickup truck on the property in conjunction with the business. Subsection N requires an applicant who does not own the property to obtain written authorization from the property owner or manager before applying. Subsection O requires the house number to be clearly posted on the home in letters at least four inches high, in a color that contrasts with the building, so the address stays readable.

Subsection P requires the dwelling and landscaped areas to be well maintained. These standards trace to Ordinance 1535, adopted in 2004, and they apply only in unincorporated Salt Lake County, not inside its cities.
