Full Breakdown
120 lists six standards a home-based business has to meet in unincorporated Lewis County. First, the business has to be on the parcel the owner or manager lives on, or on a contiguous parcel, and it has to stay clearly incidental and subordinate to the dwelling's residential use rather than becoming the primary use of the property. No more than two people who aren't part of the resident family can work in the business. 207's sign standards, there can be no change in the outside appearance of the building or premises and no other visible evidence that a business is being run there, though a home day care serving 10 or fewer children is allowed to use the yard for recreation.
Traffic generated by the business can't exceed what a residential neighborhood would normally see, parking has to meet the title's off-street parking requirements and can't sit in a required front yard, and no more than two vehicles used for the business can be parked on site at any time. Finally, no equipment or process used in the business can create noise, vibration, glare, fumes, odors or electrical interference detectable off the lot, including interference with a neighbor's radio or television reception.
Violations & Fines
A home-based business that outgrows these limits, such as adding a third outside employee, running unpermitted signage, or creating off-site noise or fumes, is a Title 17 violation: LCC § 17.07.010 makes it a civil infraction handled under Chapter 1.20 LCC and a misdemeanor, with Community Development able to treat continued operation as a separate offense for each day it continues.
