What counts as acreage on this page?

Single-family homes in Sammamish on half an acre or more, as recorded in the NWMLS listing; the data also counts the homes on a full acre or more. Half an acre is where the Eastside stops being a subdivision lot and starts being land: room for a shop, a second garage, animals where zoning allows, or privacy.

Is Sammamish acreage on a well and septic?

Often outside the city's sewer area, yes. A private well needs a current flow and water-quality test; a septic system needs a county operation-and-maintenance record and an inspection before closing. King County Public Health regulates septic; the Department of Health regulates wells. RexMont orders both as a condition of every acreage offer we write.

Can I keep horses or build a shop on Sammamish acreage?

Zoning decides. King County rural zones (RA-2.5, RA-5, RA-10) and some Sammamish residential zones allow livestock and large accessory buildings with limits on numbers and setbacks; critical-area buffers (streams, wetlands, steep slopes) shrink the buildable part of the lot. Ask for the usable acreage, not the total.

Why do acreage homes in Sammamish sell for more?

Scarcity: the Growth Management Act fixed the urban growth boundary, so no new acreage is created near the Eastside's job centers. The twelve-month median on this page against the city median is the current premium in Sammamish.

How should I sell an acreage property in Sammamish?

Document the land as carefully as the house: survey or plat, well and septic records, critical-area map, zoning letter, outbuilding permits, and the usable acreage. RexMont lists acreage with that file prepared, so the buyer's lender and inspector have nothing to discover.

How this market works

What a Sammamish home with acreage buyer is really buying

The Sammamish plateau was subdivided twice: the planned communities of the 1990s–2000s on quarter-acre lots, and before them the 1960s–80s houses on one- to five-acre parcels that survive along the plateau's edges, around Beaver Lake, off 244th and toward the Trossachs and Duthie Hill side. Those older parcels are the acreage on this page, inside the Lake Washington and Issaquah school districts.

Many are on wells and septic systems, and the plateau's wetlands and streams define the usable share of a lot. I build the well test, the septic inspection and the critical-areas map into every Sammamish acreage offer and prepare the same file before we list one.

The twelve-month data on this page is every Sammamish house closing on half an acre or more, with the one-acre-plus count separated.

Before you write

What to check before buying acreage in Sammamish

Usable acreage, not total

Steep slopes, wetlands and stream buffers are part of the parcel and not part of what you can use. Ask for the critical-areas map and walk the lines.

Well and septic

A flow and quality test on the well, and a county operation-and-maintenance record plus an inspection on the septic, before the contingency ends. Both are routine; skipping either is not.

Zoning for what you plan

Animals, a shop, a second dwelling: Sammamish's and King County's zoning say what is allowed and how big. Get it in writing from the planning desk, not from the listing.

Access and fire

A private road needs a maintenance agreement; a long driveway needs to meet fire-apparatus access rules before a permit for anything new. Insurers ask too.

Outbuildings and permits

Barns, shops and ADUs built without permits are a negotiation, not a bonus. Match every structure to a permit.

Pricing against acreage sales

Acreage homes in Sammamish price against other acreage sales, not against the subdivision down the hill. The twelve-month closings on this page are the comparable set.
