Home Remodeling Contractors in Shelton, WA

Building permits come from the city's Community and Economic Development Department, through its Permit Center. Since March 2024 most applications, document uploads, fee payments and inspection requests go through the city's online Citizen Self-Service portal, and the same department handles shoreline permits.

Every residential application needs a site plan drawn to scale, typically at one inch to 10, 20 or 30 feet. It shows property lines, a north arrow, each structure with its distance to the lines, the driveway, and any septic system, well or easement, plus spot elevations when the lot slopes. The city notes that an incomplete site plan can slow the review.

Electrical permits are not issued by the city; they come from the state Department of Labor and Industries. The city's exempt work guide says anything it does not list as exempt needs a permit before work starts, and that exempt work still has to meet the critical area, shoreline and floodplain rules.

On erosion hazard ground the code caps how much of a site may be disturbed, from all of it on slopes under 15 percent down to none on slopes over 40 percent. Those caps do not apply to an existing single-family lot smaller than 20,000 square feet created before the rules were adopted. Roof drains and other point discharges may not empty onto or above a landslide or erosion hazard slope.

Retaining walls come up often on these lots. A wall taller than four feet, measured from the bottom of the footing, or any wall holding back a slope, driveway or structure needs a building permit and plans from a Washington registered engineer, and Shelton wants footings set 12 inches into undisturbed soil. For an addition or other expansion, the City Engineer must approve a stormwater site plan that includes a small parcel erosion and sediment control plan, and bare soil gets mulch or cover through the wet season.

Shelton adopted its first Shoreline Master Program in 1975 and its current version took effect in March 2023 after state Department of Ecology review. Home lots on Island Lake, Mill Creek and part of Johns Creek carry the Residential shoreline designation, which limits impervious surface to half of the lot area inside shoreline jurisdiction and caps building height at 35 feet. Around Goose Lake the impervious limit is 30 percent.

The part of Puget Sound inside Shelton, waterward of the extreme low tide line, is a shoreline of statewide significance. Parcels in the urban growth area that are still outside city limits follow Mason County's shoreline program until they are annexed, so the rulebook for a waterfront lot depends on which side of that line it sits.

Shelton's zoning code allows an accessory dwelling unit on any lot with a single-family house, as a permitted use. The unit must have at least 300 and no more than 1,000 square feet, not counting a garage, and no more than 80 percent of the main home's floor area; a unit that fills one whole floor of an existing house or garage may be allowed to run larger. The code also asks for one added off-street parking space, and lets development coverage rise to 60 percent to fit the unit.

An ADU meets the same design rules as a house: contrasting or integrated trim or siding on every facade, a roof overhang of at least six inches and a covered entry of 20 square feet or more. The city's 2025 comprehensive plan notes that state law (House Bill 1337) requires Shelton to allow at least two ADUs on single-family lots, including detached units and conversions, so we confirm the rules in force when your permit is filed.

Shelton voted to incorporate in 1890 and is still the only incorporated city in Mason County, and its housing shows that age. Census estimates for 2020 to 2024 put the median home at 1976, with more than half built before 1980, about a third before 1960 and roughly one in eight in 1939 or earlier. About seven in ten homes are detached houses, and a little over 60 percent of occupied homes are lived in by their owners.

Forty properties are on the Shelton Historic Register. In houses of this age, opening a wall often turns up old wiring and plumbing, and we price that work line by line in writing before it starts.
