Home Business in Renton, WA

If you live in Renton or are thinking about moving there, home business are one of those things you probably won't think about until they affect you directly. Renton has 5 specific rules on the books covering different aspects of home business, and some of them might surprise you.

Zoning & Home Occupation Permits

Renton allows home occupations in dwellings and accessory buildings only when the business stays clearly secondary to residential use. RMC 4-9-090 caps the operation at 25% of gross floor area, or 500 square feet, whichever is smaller, and requires a Finance Department business license reviewed by the Community and Economic Development Administrator.

Key details: Space limit: 25% of floor area or 500 sq ft, whichever is less. Accessory building cap: 1,000 sq ft or size of home, whichever is less. Sign allowed: One nonelectric sign, max 2 sq ft. Permit needed if standards unmet: Special Home Occupation Permit from Administrator. License issuer: Finance Department, chapter 5-5 RMC.

Violations of RMC 4-9-090 are enforced under chapter 1-10 RMC, Code Enforcement, with prosecution proceeding under RMC 1-10-7, Failure to Comply. The Administrator may revoke a Special Home Occupation Permit after investigation finds noncompliance with the section's terms and conditions, and the Administrator or a designee may inspect the property before approving or renewing the associated business license to confirm the application's accuracy and that the residential character of the property is preserved.

Customer Traffic Restrictions

Renton caps home occupation customer traffic at eight visits a day, all by appointment only, with just one customer on the premises at a time. Visits are restricted to the hours of 8:00 a.m. to 8:30 p.m. under RMC 4-9-090, and only one home occupation with customer visits can operate per dwelling.

Key details: Max customer visits: 8 per day. On-premises limit: 1 customer at a time, by appointment only. Allowed hours: 8:00 a.m. to 8:30 p.m.. Home occupations with visits per dwelling: No more than 1. Business vehicles on-site: Max 2, beyond resident parking.

Violations of the customer-visit standards fall under chapter 1-10 RMC, Code Enforcement, with prosecution governed by RMC 1-10-7, Failure to Comply. The Administrator may inspect the property before license approval or renewal to verify compliance, and may revoke a Special Home Occupation Permit after an investigation finds the business exceeding its customer-visit terms or conditions.

Signage Rules

A Renton home business gets exactly one sign: unilluminated, no larger than 2 square feet, mounted flat against the wall of the house. Anything bigger, illuminated, freestanding, or in addition to that single sign is not permitted under the home occupation rule.

Key details: Number of signs allowed: One per home occupation. Maximum size: 2 square feet. Illumination: Not permitted. Mounting: Flat against wall, parallel to wall plane. Applies in: All residential, commercial, and industrial zones.

Installing more than one home occupation sign, illuminating it, exceeding the 2-square-foot area cap, or mounting it as a freestanding or projecting sign rather than flat against the building wall violates RMC 4-4-100(E)(4)(b) and makes the sign a prohibited sign subject to removal under the general sign enforcement provisions of the chapter.

This is one of the stricter rules in Renton's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
