Woodinville Home Remodeling

80.5 percent of Woodinville homes were built in 1980 or later

Woodinville is a small city of 5,626 housing units by the Census Bureau's 2020 to 2024 count, and 4,528 of them date from 1980 or later. The 1980s alone added 1,339, the largest single decade, and the median home was built in 1995. Only 49 predate 1940. In houses of that vintage the building shell is modern, so projects center on replacing worn parts: roofing, windows, furnaces and heat pumps, and the kitchens and baths inside.

Little Bear Creek carries Chinook and Coho salmon through town

Little Bear Creek flows through Woodinville into the Sammamish River, and the city calls it critical habitat for runs of Chinook, Sockeye, Kokanee and Coho salmon, including spawning grounds for threatened and endangered species. At NE 195th Street the city is replacing two concrete culverts with a bridge to reduce flooding. For owners along the creek, the stream buffer changes what you can do in the yard: trimming or removing trees in a critical area or its buffer is prohibited unless a certified arborist and the city confirm the tree is hazardous, dead or a nuisance.

Woodinville caps tree removal at four trees per permit

Woodinville counts a tree as significant once its trunk reaches 6 inches across, measured 4.5 feet up. On a single-family lot with no construction under way, one tree permit can cover up to four trees, and a property can use two permits of that kind. Beyond that, the lot has to meet the zone's minimum tree density, 70 credits per acre in R-1 zones and 50 in R-4 through R-8, or be replanted. Thinning more than four trees at once needs a certified arborist's report and three replacement trees for each one removed.

How much is a building permit for a remodel in Woodinville?

Woodinville bases the fee on the declared project value, labor included. Under the 2026 schedule, a $150,000 project pays $2,010 for the building permit, plus plan review that usually runs 65 percent of that fee and a $4.50 state fee. Mechanical and plumbing permits are priced by fixture, and electrical permits are bought from the state.

Who issues electrical permits in Woodinville?

The Washington State Department of Labor and Industries, not the city. Woodinville issues building, mechanical, plumbing, fire and tree permits through its Accela portal, but its permit FAQ sends electrical work to the state agency. Plan on two separate permits when a kitchen or bathroom remodel adds circuits or moves outlets.

Does Woodinville require a tree removal permit?

Yes. The city's permit FAQ says a Tree Removal Permit is required to remove any tree on private or public property. On a single-family lot without construction, one permit covers up to four trees, with two such permits allowed. Trees in stream or wetland buffers can only come down if an arborist and the city confirm they are hazardous.

Is a reroof permit required in Woodinville?

For a single-family house, only if the job modifies or replaces the roof sheathing, the wood decking under the shingles. A straight reroof over sound sheathing needs no permit. Multifamily and nonresidential buildings need a permit for any roofing project. When a permit is needed, the application goes through Woodinville's Accela portal.

Can I build an ADU in Woodinville?

Yes, up to two per lot where the zone allows ADUs. Each must have between 300 and 1,500 square feet of habitable floor area. A legally built detached garage can be converted even if it does not meet current setbacks, a detached unit can sit on an alley line, and ADUs cannot be rented for fewer than 30 nights.
