Who handles zoning in Fairfax County
The county website lists a Code & Zoning page at Code & Zoning. Treat it as the front door: contacts, the ordinance, and application forms tend to live there. We opened it on October 13, 2026; no sign-in was needed.
Check who has jurisdiction first
A county ordinance generally governs land outside city limits; inside a city, the city's code applies. Not every county zones every acre; some regulate only floodplains, subdivisions or certain districts.
Looking up a parcel's zoning in Fairfax County
Find the parcel on the official Fairfax 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.
Start from the parcel map
Our Fairfax County page links the official county parcel viewer, where you can find owner names, parcel numbers and acreage.
What zoning controls
A district sets permitted and conditional uses, minimum lot area and frontage, setbacks, and height limits. If a plan doesn't fit, the usual routes are a variance (relief from a dimension) or a rezoning (a change of district), each with notice and a hearing.
Why buyers should look first
A cheap lot isn't a bargain if the district won't allow your plan, so check zoning early. Zoning is one piece. Septic suitability, access and flood zones can also stop a project.
Zoning permits and building permits
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. Skipping permits can cause problems at resale, when buyers and lenders ask for records.
Overlays, floodplains and rural uses
Base zoning is only part of the picture. Floodplain and other overlays can add requirements. If the land is farmed, ask whether agricultural exemptions apply to the buildings or uses you have in mind. Land splits trigger subdivision review in many counties, ending with a recorded plat.
Where zoning is headed
A comprehensive plan's future land-use map shows how officials expect areas to develop. Look at the plan's map for nearby changes that could affect value or use. Remember that the plan isn't binding the way the ordinance is.
What to ask staff
Lead with the parcel ID and a short description of what you want to build or do. 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. If the answer matters for a purchase, ask for it in writing. Some offices issue a formal zoning verification letter.

Frequently asked questions
Where can I check zoning in Fairfax County?
Start with the Code & Zoning page on the county's official website (Code & 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.
Is the zoning map legally binding?
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.
