Full Breakdown
Sec. 5 through RPD 80, and Sec. 025(g) cross-references the same subsection as the source of the city's Home Occupation Permit requirement. " The operating standards in clause (a) require the business to leave no visible trace: it cannot alter the dwelling's exterior appearance, must be confined completely to a single room inside the house, and cannot use any part of a garage, carport, or accessory structure. It also cannot encroach into required parking, setback, or open-space areas, cannot involve commercial deliveries or on-site sales, and can only employ people who actually live in the home, so hiring outside workers to come work in the house is prohibited outright.
Clause (b) then lists specific uses the city has determined are never compatible with a residential home occupation regardless of scale, including adult businesses, barber and beauty shops, medical and dental offices, dance and night clubs, gun and rifle shops, vehicle repair, welding, and mini storage, among others. A property owner's written authorization is required before a home occupation can operate on rental property.
Violations & Fines
Operating a home occupation that violates the appearance, single-room, or employee restrictions in Sec. 9.10.020(b)(5)(a), or that falls on the prohibited-use list in (b), is a code violation under Sec. 1.01.200: a misdemeanor with up to a $1,000 fine and six months in jail, or a cited infraction with $100/$200/$500 tiered fines, plus possible revocation of the Home Occupation Permit referenced in Sec. 9.10.025(g).
