Lynnwood, WA Home Business: Zoning & Home Occupation Permits (2026)

35 of the Unified Development Code, the use-regulation chapter that applies across every residential zone, including RN. Subsection (A)(1) makes the business license, issued under LMC Title 5, the gateway: without it, and without compliance with 'this and other applicable sections' of the code, there is no lawful home occupation. Subsection (A)(2) then locks the use to the principal building; an accessory structure like a detached garage or shop only qualifies if it independently meets the habitability standards of LMC Title 16 (the building code), and even then the home business portion cannot exceed 25 percent of the principal building's floor area.

Subsection (A)(3) closes off the outdoors entirely: no paving a yard for customer or business parking, no outdoor storage or outdoor activity, and no activity that is merely visible from outside the house, whether that is stacked inventory near a window or equipment left on a porch. Read together with the separate limits on noise, traffic, and the flat list of prohibited trades in (A)(7), the zoning rule is built to keep a home occupation invisible to the street: a resident can run a bookkeeping practice, a craft business, or consulting work from a spare bedroom, but cannot convert the house into a storefront, a shop yard, or a warehouse.

The city's development administrator checks these standards when the Title 5 business license application comes in, and can flag a use for exceeding the 25 percent cap or for any outdoor spillover at that stage.
