Full Breakdown
Municipal Code § 18.32.020(G)(10) and (G)(12) cap home occupation traffic: no more than one vehicle may be associated with the business, and it must be parked in an enclosed garage or designated carport when not in use, or in an approved driveway if the lot lacks a garage or carport. The occupation also may not create excessive pedestrian, automobile, or truck traffic in the vicinity, a broader standard the City enforces case by case against neighbor complaints and observed activity at the property.
Violations & Fines
Associating more than one vehicle with the business, parking that vehicle on the street instead of a garage, carport, or driveway, or generating traffic neighbors and the City find excessive violates § 18.32.020(G); it can void the home occupation's permitted-use status.
