Bellevue, WA Home Business: Signage Rules (2026)

Bellevue applies a strict no-visible-signage rule to home-based businesses under LUC 20.30L. The fundamental standard is that a home occupation must not change the residential character of the dwelling or the neighborhood, which means the business cannot be visible or apparent to anyone viewing the property from off-site. No exterior signs, lighted signs, window signs, banners, A-frames, yard signs, or vehicle signs parked overnight at the residence are allowed if they advertise the home occupation. Business names, addresses, or phone numbers cannot be displayed on the dwelling exterior. The city does allow a reasonable interior display of business licenses and required postings out of public view. Bellevue Sign Code BCC 22B.10 does not authorize residential district business signs; any proposed signage would require a variance, which is rarely granted. Even temporary signs (contractor-style A-frames, open house style) are not permitted for home occupations. Commercial vehicles parked overnight must comply with residential parking restrictions. Internet-based advertising is not restricted.
