Full Breakdown
Under Nampa's home occupation standards, a residential business can display no sign other than a nameplate, and that nameplate cannot exceed two square feet or be illuminated in any way. The rule sits inside the broader home occupation ordinance (City Code § 10-1-10), which governs any small-scale business run from a dwelling in any residential zoning district: home offices, craft-making, in-home daycare, and similar ventures. Because the standard is written into the home occupation permit conditions, the same section makes violating any of the listed standards, signage included, a misdemeanor enforced by the city's planning department upon complaint.
Violations & Fines
Violating any home occupation standard, including the signage limit, is a misdemeanor under City Code § 10-1-10.C, and the city can revoke the home occupation permit after a substantiated complaint.
