Full Breakdown
MMC § 22C.190.020 lets residents run a home occupation in any residential zone (the permitted-use table lists it as allowed in all seven zones under § 22C.010.070(5)) as an accessory to the dwelling. The space is capped at 25 percent of the unit's floor area or 600 square feet, whichever is less; only one employee from outside the family is allowed; no equipment or materials may be stored outdoors; sales are limited to items made on-site, mail order, or off-site delivery; and traffic is capped at 10 average daily customer round trips. A nontransferable home occupation permit is required, and multifamily units are limited to home-office uses only.
Violations & Fines
Exceeding the 600-square-foot/25-percent space cap, employing more than one outside worker, storing materials outdoors, or generating more than 10 customer trips a day without a permit violates MMC § 22C.190.020 and can trigger permit revocation.
