Before you build, split or buy land, look at the washington county zoning and the ordinance behind it. Here's the verified official page and a simple routine for finding a district.
Washington County zoning office and link
Washington County's official site has a Zoning page, linked here: Zoning. Treat it as the front door: contacts, the ordinance, and application forms tend to live there. We confirmed it loaded publicly, with no login, on October 13, 2026.
County zoning vs. town zoning
County zoning normally covers unincorporated land. Incorporated cities and towns usually adopt their own zoning codes. Parcels inside Belpre, Beverly, and Lower Salem may follow municipal zoning instead of the county's. If a county has no general zoning, other rules such as subdivision, septic or floodplain permits can still apply.
Looking up a parcel's zoning in Washington County
Find the parcel on the official Washington County parcel viewer and note its parcel number. Next, match that parcel to a district on the zoning map, or email the office with the parcel number. District codes like A-1, R-1 or C-2 are only shorthand. The ordinance text spells out what each one allows.
The free parcel map helps
The official parcel viewer, linked from our Washington County directory page, gives you the parcel ID and owner to bring to this office. For more on using the map itself, see our Washington County map guide.
Uses, setbacks and lot size
Zoning decides what you can do on land: which uses are allowed outright, which need a special permit, how big a lot must be, and how far buildings sit from lines and roads. Variances and rezonings exist for projects that don't fit, but both involve applications and public hearings.
Check zoning before you buy
Before you buy acreage for a house, barn or business, confirm the district allows it. Also ask about road frontage, septic approval and floodplain rules, which are often handled by other offices.
From zoning approval to building
Expect a sequence: zoning sign-off, then building and trade permits, then inspections. The office page or staff can tell you which permits your project needs and in what order. Starting work without the required permits can bring stop-work orders or fines, and trouble when you sell.
Other layers that can apply
Base zoning is only part of the picture. Floodplain and other overlays can add requirements. Agricultural land is often treated differently, and farm buildings may be exempt from some permits, so ask how the county handles farm use. Land splits trigger subdivision review in many counties, ending with a recorded plat.
Long-range plans
Many counties adopt a comprehensive or land-use plan that guides future zoning decisions. If you're buying for the long term, ask whether the plan calls for change near the parcel, such as new commercial corridors or areas set aside for farmland. The ordinance governs now; the plan describes intent.
Getting a clear answer
Have the parcel number and a simple sketch or description of the project ready. Ask what district the parcel is in, whether your use is permitted or conditional, the setbacks and minimum lot size, and whether any overlays apply. For a sale or a loan, a written zoning verification beats a phone call.
Washington County at a glance

Common questions
Where can I check zoning in Washington County?
Start with the Zoning page on the county's official website (Zoning), then confirm the district with staff.
Does county zoning apply inside towns?
Usually not. Incorporated cities and towns generally run their own zoning, so check which government has jurisdiction over the parcel.
Can I rely on an online zoning map?
The adopted ordinance and official map control. Online maps are for reference, so confirm with the office in writing before you rely on them.
How do I change a property's zoning?
You apply for a rezoning or a variance. Both usually involve fees, public notice and a hearing before a planning board or governing body.
Does zoning show property lines?
Zoning maps show districts. For lines, use the parcel map, and for exact boundaries use a licensed survey.
