The Real Cost of Owning a Home in Sequim, WA
A Sequim listing price is only the starting line. Between a genuinely disagreement-prone home-price market, Washington's distinctive property tax structure, an irrigation-water system that still runs through 19th-century ditch companies in parts of the valley, and a lack of state income tax that changes the math for a relocating retiree, the full cost picture here looks meaningfully different from most markets this site covers. This page lays out each real cost line item with its actual source, and flags plainly where a firm number could not be confirmed.
Purchase Price: Three Sources, Three Different Numbers
Sequim is a small, thin real estate market, and it shows in how much its major listing-data sources disagree with each other. A Redfin snapshot put the median sale price around $489,950 to $495,000, up 5.8% year-over-year. Zillow's typical-home-value estimate for the same broad period ran considerably higher, at $563,761, itself down 2.4% year-over-year. A separate August 2026 listing-price snapshot cited a $550,000 median asking price, down roughly 15% from the year before. None of these three numbers is wrong exactly -- they measure different things (closed sales versus algorithmic valuation versus current asking prices) in a market small enough that a handful of unusual transactions can swing a monthly median noticeably. The practical takeaway for a buyer: treat any single site's headline number as directional, pull a current comparative market analysis from a local agent working actual Sequim MLS data, and expect meaningful variation by neighborhood -- waterfront-adjacent parcels near Sequim Bay, view lots on the bluffs above the Dungeness Valley, and in-town properties near downtown price very differently from acreage out toward Carlsborg or the Dungeness Valley farmland.
Beyond the headline median, Sequim's housing stock itself skews differently than a typical coastal resort town: a meaningful share of the market is 55-plus age-restricted or manufactured/mobile home community product -- places like Sunland Golf and Country Club, Vintage at Sequim, and Lavender Meadows -- which carries its own cost structure (HOA or lot-lease fees, community amenities, resale restrictions) distinct from a standard single-family purchase. A buyer comparing a $495,000 Redfin-cited median against a manufactured-home listing in a 55-plus community, or against a custom-built home on acreage in the Dungeness Valley, isn't comparing like properties, and this page won't pretend those are interchangeable data points.
Washington's Property Tax Structure: A 1% Levy Limit, Not an Assessed-Value Cap
Washington's property tax system works differently than the assessed-value-growth caps used in Oregon (Measure 50) or California (Proposition 13). The Washington State Constitution limits the maximum aggregate regular property tax levy on an individual parcel to 1% of true and fair value -- commonly called the $10-per-$1,000 limit, since rates are expressed per $1,000 of assessed value. Crucially, that 1% figure caps how much a taxing district's total levy can grow year to year (absent a voter-approved lid lift), not the tax rate applied to any one property; and Washington generally assesses property at its full current market value, reassessed regularly, rather than capping the taxable value's own annual growth the way Oregon does. Clallam County is what the state calls an annual revaluation county, meaning every property gets a new assessed value each year, layered on top of a state-mandated six-year cycle of physical, on-site property inspections.
For 2025, Clallam County's own primary (general-fund) property tax rate was cited at $0.95 per $1,000 of assessed value -- but that figure alone significantly understates a typical bill, since it excludes the city, school district, fire district, port district, and any other overlapping special-district levies that also apply to most Sequim parcels. One property-data aggregator (Ownwell) puts Sequim's effective combined tax rate somewhere in the 0.75% to 0.87% range of assessed value, which this page treats as a useful directional estimate rather than a confirmed figure for any specific address. This site's dedicated Property Tax Guide page for Sequim goes into the full mechanics; the short version for cost-planning purposes is that a $500,000 Sequim home might reasonably land somewhere in the $3,750 to $4,350 annual property tax range at that effective-rate estimate, but the only way to know an exact number for a specific parcel is to pull its current combined levy rate from the Clallam County Assessor's Office.
No State Income Tax -- A Real Structural Advantage, Especially for Retirees
Washington levies no state income tax of any kind. For a retiree relocating to Sequim from a state that taxes retirement income, this is not a marginal detail -- Social Security benefits, pension payments, 401(k) and IRA distributions, and any other retirement income arrive completely free of state tax. Washington does have a capital gains excise tax (enacted 2021, upheld by the state Supreme Court in 2023) that applies a 7% rate to certain long-term capital gains above an inflation-adjusted annual threshold, but real estate sales are explicitly exempted from that tax -- a homeowner's gain on selling a Sequim house is not subject to it. This is a genuinely different tax structure than Oregon just across the peninsula (no sales tax, but a real income tax) or California (both income and sales tax), and it's worth running an honest side-by-side of total tax burden -- property tax plus sales tax plus zero income tax -- against wherever a buyer is currently living, rather than assuming any single tax line item tells the whole story.
Washington's combined sales tax in Sequim is cited at 9.5% as of 2026 across multiple tax-tracking sites, composed of the 6.5% statewide rate plus local county and district components -- higher than several neighboring jurisdictions' rates, and a real, recurring cost on furniture, vehicles, building materials, and most other taxable purchases made locally. This page did not find a confirmed breakdown of exactly how that 9.5% splits between county and any sub-county taxing districts specific to every Sequim address; confirm the current combined rate for a specific purchase with the Washington Department of Revenue.
Irrigation Water: A Real, Distinctive Cost in Parts of the Valley
One cost line item genuinely specific to the Sequim-Dungeness Valley, and unfamiliar to most buyers coming from elsewhere: parts of the valley's agricultural and residential land still draw irrigation water through a network of ditch companies dating back to the Sequim Prairie Ditch Company's original 1895-96 system, which by 1930 had grown to twenty-one separate ditch companies irrigating roughly 12,000 acres. A property with water rights tied to one of these ditch systems, or within a modern irrigation district's service area, may carry an annual water-right assessment or ditch-company fee on top of standard municipal utilities -- a cost that varies by parcel, by ditch company, and by whether the property is inside city limits (served by the City of Sequim's municipal water system) or out in the unincorporated valley. This page does not have a confirmed current fee schedule for any specific ditch company or irrigation district, since these are locally administered, parcel-specific arrangements rather than a single citywide rate.
A buyer looking at acreage, farmland, or a rural property anywhere in the Dungeness Valley should ask directly, before making an offer, whether the parcel carries water rights through a specific ditch company or irrigation district, what the current annual assessment is, and whether that obligation transfers automatically with a sale -- a materially different due-diligence step than a typical in-town residential purchase, where standard City of Sequim water and sewer utility billing applies instead.
Utilities, Insurance, and Everyday Running Costs
In-town Sequim properties are served by City of Sequim water and sewer utilities, with rates set through the same municipal budget process that set the FY2026 city budget at roughly $51.6 million. This page does not have confirmed current monthly water/sewer utility rates for a typical Sequim household and recommends pulling current rate schedules directly from the City of Sequim's Public Works Department, since utility rates are adjusted periodically through the city's own budget cycle. Electric service in the area is generally provided by Clallam County Public Utility District No. 1, a public utility rather than an investor-owned utility, which in many Washington PUD territories translates to comparatively lower residential electric rates than the national average -- though this page did not confirm a specific current per-kilowatt-hour rate for Clallam PUD.
On insurance, Washington homeowners policies typically cover windstorm damage under a standard policy (unlike hurricane-exposed states that require a separate wind carrier), but earthquake coverage is a separate, optional policy that most standard homeowners insurance excludes entirely -- worth budgeting for explicitly given the region's real, documented Cascadia Subduction Zone exposure, covered in depth on this site's Hurricane & Storm Risk and Coastal Insurance pages. No Sequim-specific homeowners or earthquake insurance premium was confirmed this research pass; get an actual quote from a Washington-licensed broker before budgeting a number.
What This Page Does Not Know
This page does not have a confirmed single combined property tax rate applicable to a specific Sequim parcel, since Washington's overlapping-district system genuinely varies by exact tax code area; a confirmed current fee schedule for any specific irrigation ditch company or water district serving Dungeness Valley properties outside city limits; confirmed current City of Sequim water and sewer utility rates; or a confirmed current Clallam County PUD electric rate.
Before making a purchase, get a current comparative market analysis from a local Sequim buyer's agent working actual MLS data rather than a single listing site's snapshot, confirm the exact combined property tax rate for a specific parcel with the Clallam County Assessor's Office, confirm any water-right or ditch-company obligations for a rural or agricultural parcel directly with the relevant ditch company, and get a real insurance quote -- including a separate earthquake policy quote -- from a Washington-licensed broker.
