Anderson Island, WA: The Real Cost of Ownership, Beyond the Mortgage
A home price on a listing site is the beginning of the budget on Anderson Island, not the end of it. Because this is unincorporated, ferry-only Pierce County land, several costs here don't exist -- or work differently -- than they would on a mainland property ten minutes from a freeway. This page walks through what's real, what's confirmed, and what a buyer needs to call and verify before writing an offer.
The Purchase Price Itself Is a Genuinely Unsettled Number
Two market snapshots pulled during this research disagree meaningfully. Redfin's own November 2025 data showed a median sale price of $600,000 on Anderson Island, reportedly up 49.1% year-over-year -- a striking jump in a market this small, where a handful of unusual sales can swing a median hard. Movoto's own August 2026 snapshot showed a $465,000 median list price, itself down from the prior month and year. Those are two different metrics (sale price versus list price) pulled at different times from a small, thin island market, and this page isn't going to average them into a fake consensus number. What's true either way: this is not a market where a single site's headline price should anchor a budget. Pull current comparable sales directly from a local agent who works Anderson Island listings regularly, not a national aggregator's rolling average.
The island's real-estate inventory also skews toward a mix that a mainland buyer may not expect: modest, older cabins built for a retirement or vacation-home market sit alongside newer construction and waterfront lots, and the island's documented population growth (64% since 2015, per an October 2025 Spokesman-Review report) has been pulling in more year-round and short-term-rental buyers than the retirement-community reputation alone would suggest. That mix matters for price comparison -- a $465,000-$600,000 median blends very different property types, and a specific waterfront or updated home can run well above either figure.
The Ferry: A Real, Recurring Line Item, Not a One-Time Cost
Every vehicle trip on or off the island costs a round-trip fare, collected at the Steilacoom terminal, on the Pierce County Ferry System -- a cost that simply doesn't exist for a mainland property. A Pierce County Council ordinance sets fare increases of 5% for 2026 and another 5% for 2027, but this research could not pull the resulting current dollar figures from the county's own fare table; confirm today's walk-on and vehicle rates directly at piercecountywa.gov/2201/Fares or by calling (253) 588-1950 before budgeting. For a year-round resident who commutes off-island for work, medical care, or regular errands, that fare is a real, recurring transportation cost on top of gas and vehicle wear -- and it's worth running the actual math for your household's expected trip frequency before assuming island living is automatically cheaper than mainland living.
There's a second, less obvious ferry-adjacent cost: time. The Pierce County Ferry runs on a no-reservation, first-come-first-served basis, with vehicles and passengers required to be in line with tickets 20 minutes before departure -- and on a route serving a genuinely growing island, wait times during peak periods are a real, currently-reported source of resident frustration, not a hypothetical. See the Island Logistics page for the full access picture, including documented mechanical-reliability issues with the county's aging ferry fleet.
Property Tax: No City Levy, But More Special Districts Than You Might Expect
Washington has no state income tax, which shifts more of the state and local funding burden onto property tax. Because Anderson Island is unincorporated Pierce County land with no city or town government, there's no municipal levy layered on top the way there would be on, say, Bainbridge Island -- but that doesn't mean fewer taxing districts. A specific Anderson Island parcel sits within Pierce County's general levy, the state school levy, the Steilacoom Historical School District, Pierce County Fire Protection District #27 (Anderson Island Fire & Rescue), the Pierce County Rural Library District, and the Anderson Island Park & Recreation District -- a real, independently-taxing special district that funds and manages Jacobs Point Park and Andy's Marine Park. See the dedicated Property Tax page for the full framework, including Washington's statutory 1% levy-growth limit and the separate $5.90-per-$1,000 constitutional aggregate-levy limit referenced in Pierce County's own levy materials.
None of those district rates were independently pulled and combined into a single current dollar figure for this page -- that's exactly the kind of number that changes by tax code area and by year, and the Pierce County Assessor-Treasurer's office is the only source that can give you the actual combined rate and assessed value for a specific parcel.
Insurance: Two Separate Policies Most Mainland Buyers Don't Carry
Standard Washington homeowners insurance does not cover earthquake damage -- a separate earthquake policy or endorsement is the normal way that gap gets covered statewide, not something unique to this island, but worth budgeting for given South Puget Sound's real (if generally lower-intensity-here-than-outer-coast) seismic exposure, covered in detail on the Hurricane & Storm Risk and Coastal Insurance pages. No Anderson Island-specific earthquake premium was confirmed this research pass; get an actual quote from a Washington-licensed agent for the specific property.
Waterfront and bluff-adjacent parcels can also face insurance and financing wrinkles tied to shoreline stability and flood-zone mapping -- covered fully on the Flood Zones and Beach Erosion pages. And because emergency response here runs through a volunteer fire district reliant partly on ferry-dependent logistics for anything beyond on-island capability, ask an insurance agent directly whether that affects fire-protection-class ratings (ISO ratings) and premiums for a specific address, since this research did not confirm Anderson Island's current fire-protection classification.
Maintenance, Delivery, and the Cost of Everything Not Being Same-Day
A single general store operates near the island's Riviera area -- real, but not a full-service supermarket, gas station network, or big-box retailer. Most owners plan on a regular mainland run for groceries, hardware, and larger purchases, which folds ferry fares and travel time into an otherwise ordinary errand. A contractor's truck, a delivery of new appliances, or a large landscaping project also has to cross by ferry, meaning scheduling and cost structures for home projects here don't match a mainland job's same-day-delivery assumptions. This research did not confirm specific freight or delivery surcharges that island-based or mainland contractors typically apply for Anderson Island jobs -- ask directly, and build in extra lead time when budgeting a renovation or repair.
Well and septic systems are common on an island without municipal water and sewer infrastructure covering every parcel -- a real, recurring maintenance cost category that a buyer moving from municipal-utility mainland housing should budget for and have professionally inspected before closing, since neither system's condition transfers from a listing description alone.
What This Page Won't Guess
This page does not state a single reconciled median home price, a specific current ferry fare in dollars, a combined property tax rate for a typical parcel, or a specific insurance premium range for an Anderson Island address -- all four require either a current local agent, the Pierce County Assessor-Treasurer, the Pierce County Ferry System, or a Washington-licensed insurance broker, and this page names each of those gaps directly rather than filling them with an invented number.
The honest summary: Anderson Island ownership costs include everything a mainland Puget Sound property costs, plus a real, recurring ferry-fare line item, plus a real time cost tied to ferry schedule and capacity, plus insurance and maintenance categories (earthquake coverage, well/septic upkeep) that a municipal-utility mainland buyer may not be used to budgeting for. None of that makes the island unaffordable -- it makes the true cost of ownership here different in composition from a mainland comparison, and worth modeling with real, current numbers before an offer rather than a listing price alone.

Washington's lack of a state income tax and its statutory property-tax framework are confirmed via the Washington State Department of Revenue's general materials, consistent with the framework already used on this site's Bainbridge Island Property Tax page. Standard Washington homeowners insurance excluding earthquake coverage is general statewide fact, not Anderson Island-specific. Facts not independently confirmed and not invented here include: a single reconciled current median home price; specific current ferry fares in dollars; a combined current property tax rate for a typical Anderson Island parcel; specific insurance premium ranges for an Anderson Island address; the island's current ISO fire-protection classification; and typical freight/delivery surcharges applied by contractors serving the island. Confirm all current figures directly with a local buyer's agent, the Pierce County Assessor-Treasurer, the Pierce County Ferry System, and a Washington-licensed insurance broker before making a purchase decision.
