Home Remodeling Contractors in Stanwood, WA

The City of Stanwood Community Development Department reviews building, land use and construction permits, and applications go in online through its permit portal: you download the right form, fill it in, then upload it with the plans. The city's own guidance says almost all construction needs a permit, including remodels, additions, structural changes, new plumbing fixtures and re-roofing.

Depending on the job, the city may ask for a site plan, architectural plans, structural engineering, a geotechnical report and specifications. Residential plumbing, mechanical and re-roof permits are issued as soon as the fee is paid; other applications are reviewed, and staff contact the applicant when the permit is approved or more documents are needed.

Staff offer a general information meeting at no charge to talk through zoning, setbacks, utilities and fees, and a paid pre-application meeting with planning, building, public works and engineering at one table. Once a permit is ready to issue, the applicant has six months to collect it. Every subcontractor on the job also needs a City of Stanwood business license. The city does not publish review times.

The flat ground of the Stillaguamish floodplain sits only four to five feet above mean sea level, while the hills to the east rise to 100 or 200 feet. The city's flood code lists river flow, high tides combined with high winds, and sea level rise among the sources of flood hazard, and it adopts the Flood Insurance Study for Snohomish County dated June 19, 2020, with its rate maps.

Inside a mapped special flood hazard area, a floodplain development permit is needed before construction starts, on top of the building permit. Enclosed space below the lowest floor that could flood is limited to parking, access or storage, and it must have flood openings that let water in and out. Because the 50 percent test counts all work over a 12-month period, a large remodel on a lower west Stanwood street is scoped with that threshold in view from the start.

Stanwood adopted its current Shoreline Master Program on July 27, 2019, through Ordinance 1475, together with shoreline jurisdiction maps. The Stillaguamish River is named in it as a shoreline of statewide significance, so projects on it are weighed against statewide interests as well as local ones.

The program sets reach by reach standards along the river: several reaches carry a native vegetation buffer of 40 feet from the ordinary high water mark, Irvine Slough carries 35 feet in one reach, and the Church Creek reaches are subject to stream, wetland and steep slope buffers. Under the critical areas code, an existing house can be maintained, repaired and remodeled as long as the work does not push further into a critical area or its buffer.

East of the escarpment, most of the city stands on a glaciated plateau of poorly drained loams over clay-rich hardpan, which pushes water sideways toward the plateau edge. The city's plan notes that soils in the creek gullies and along that edge carry moderate to severe erosion and slippage ratings.

The critical areas code lets a house addition or accessory building go ahead without a geotechnical report where the hazard is slight or low, provided it does not affect streams, wetlands or their buffers. On moderate or steep slopes the report comes first, and roof drains and other point discharges cannot simply be released onto or above an erosion or landslide hazard area.

Stanwood rewrote its accessory dwelling unit standards in 2025 with Ordinance 1549. A lot with a house may have two ADUs, attached or detached, each at least 300 square feet. A unit built inside the existing house or a converted garage may reach 1,200 square feet; a detached unit or an addition may reach 1,000 square feet on a lot under 12,400 square feet, and 1,200 square feet on a larger lot.

An ADU may be up to 24 feet tall, follows the setbacks and lot coverage of the zone, and needs one parking space. A detached unit must share at least one element with the house, such as roof pitch, window frames, color or siding, must have its own water meter, and cannot be a yurt, an RV or a shipping container. ADUs may not be used as short-term rentals, and any private covenants on the lot still apply.

Stanwood grew as two towns: the original river settlement and East Stanwood, platted in 1906 around the Great Northern Railroad a mile to the east; the two merged into one city in 1960. The city's land use plan records that housing on the west side is generally older, with smaller lots, while the new subdivisions have been built on the higher ground to the east.

The Census Bureau's 2020 to 2024 American Community Survey shows how young the housing stock is overall: the median Stanwood home dates from 2001, roughly half of all homes were built in 2000 or later, and about two in three are detached single-family houses. Around 200 homes date from before 1940. A remodel on the plateau usually means updating finishes and layout in a newer house, while an older west side home can hide dated wiring and plumbing that we price in writing before work starts.
