Full Breakdown
10 specifically governs advertising. Off-premises advertising for a Rapid City home occupation, such as in a directory listing, is restricted to a phone number only, with no address, business name, or other identifying detail. On-premises signage is capped at exactly 1 nonilluminated sign, no larger than 1 square foot, and the legend on that sign may show only the occupant's name and the type of occupation, in a neutral color; illuminated signs, larger signs, or signs advertising products or services beyond the occupation's name and type are not allowed.
8's broader rule that a home occupation cannot require external alteration of the residence or any other visible evidence that a business operates there, meaning the single small sign is effectively the only exterior marker a home business may display. 030 rather than being allowed by right.
Violations & Fines
Posting an illuminated sign, a sign larger than 1 square foot, or more than one sign for a home occupation violates § 17.50.350.C.10 and, combined with subsection C.8's ban on visible evidence of the business, can trigger a Code Enforcement notice to remove or downsize the sign. Repeated or advertising-related violations can push the use into 'major home occupation' status, requiring a conditional use permit under § 17.54.030.
