Zoning Restrictions
Kennewick regulates home occupations through KMC Title 18 (Zoning) under authority of RCW 35A.63 (Planning and Zoning in Code Cities) and the Growth Management Act. Home occupations are typically permitted as accessory uses in residential districts subject to limits on the floor area devoted to the business, exterior changes to the dwelling, non-resident employees, customer traffic, signage, outdoor storage, and noise. Washington has no statewide home-occupation preemption statute, so the precise standards (often distinguishing Type 1 by-right and Type 2 conditional-use home occupations) are set by KMC Title 18. The Kennewick Municipal Code is on Code Publishing.

Some RestrictionsSignage Rules
Signage for home occupations in Kennewick is governed by the sign regulations in KMC Title 18 (Zoning), typically a dedicated sign code chapter. Typical home-occupation rules in Washington cities limit on-premises signs to one non-illuminated wall sign of small area (commonly 1 to 2 square feet) identifying the business. Type 2 home occupations approved by conditional-use permit may receive modest additional signage rights subject to the Sign Code. All sign regulations must be content-neutral under Reed v. Town of Gilbert, 576 U.S. 155 (2015); Kennewick may regulate size, height, location, illumination, and duration but cannot impose different rules based on the message conveyed. The Kennewick Municipal Code is on Code Publishing.
