Ahead of any building plan near Mattawa, check the Quincy zoning map before anything else: the zoning district can make or break the plan. This Quincy guide covers: who controls zoning for a given parcel, how to match a parcel to its district, and what to ask the planning staff.
Which office controls the Quincy zoning map
Within municipal limits, zoning usually comes from the municipality, so a lot in Quincy is governed there. Outside those limits, near Ephrata or Mattawa, the county's ordinance, if any, takes over; the county planning or zoning office can confirm. A fast way to settle it: ask whether the parcel near George is inside the boundary.
Getting to the right map
Your first stop is the Washington Current Parcels layer in ArcGIS Map Viewer; it maps every tax parcel from Moses Lake to Ephrata. For land near Mattawa, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Grand Coulee, the record panel typically gives the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Next door to Grant County
Grant County borders Adams County, Benton County, Douglas County, Franklin County, and Kittitas County, and each of those keeps its own parcel map. Ground near George that runs to the line may show up in two county records, so check the adjacent map before you assume the acreage. For acreage around Ephrata, our state page links every bordering county map across Washington.
Where Quincy fits in
Quincy lies within Grant County, Washington, which means parcel data comes from the county. For a tract near Moses Lake, City or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the town limits toward Moses Lake usually answers to county rules instead.
How to look up the district
Start by finding the parcel on the Washington Current Parcels layer in ArcGIS Map Viewer, note the parcel number, and match it to the adopted zoning map. For land near Ephrata, short codes on the map point to a table of rules in the ordinance; don't assume a code means the same thing everywhere.
Grant County in a few facts
Ephrata is the county seat, home to the main records offices. Smaller places on the map include George, Electric City, and Grand Coulee. Roughly 102,678 people live in Grant County (Census estimate, 2023) on roughly 2,680 square miles. Grant County was formed in 1909, and some chains of title near Mattawa are long. Features like Columbia National Wildlife Refuge make handy reference points on the map near George.
A word on accuracy
Parcel lines are drawn for taxes, not surveyed, so a fence near Mattawa can sit some distance off the line on screen. For a home near Ephrata, records update in batches, so a deed recorded last month might lag behind.
Who handles what
Questions about value or the owner field for land near Mattawa belong with the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Mattawa go to planning, building or health offices, town or county, depending on location.
Recorded documents worth pulling
When the details count, get the recorded deed from the County Auditor; the parcel map near Mattawa only summarizes it. Long-held tracts near George may trace back through a long string of deeds, and a title company can sort it out on a real sale.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Electric City, though signal can drop in rural spots. A screenshot of the parcel near Grand Coulee with its ID helps when you meet an owner or agent.
What to ask before you buy
When you call about land near Ephrata, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Also ask whether the lot near Grand Coulee is a legal lot of record, since some older splits don't.
Permits after zoning
Once zoning clears a project near Mattawa, you still need building permits and inspections; health and road departments may weigh in on land near Moses Lake.
Setbacks, lot size and uses
For any structure near George, check minimum lot size, setbacks from each line, height limits and lot coverage. Closer to Electric City, overlay districts, whether historic, floodplain or corridor, can add rules on top of the base district.
When a plan doesn't fit
For a tract near Mattawa, expect an application, a fee, notice to neighbors and a public hearing.
