Boone County zoning office and link
The county website lists a Zoning County Ordinance page at Zoning County Ordinance. It's an office page rather than a map, so use it for contacts, ordinances and applications. 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. In Boone County, places such as Beaver, Berkley, and Boxholm are incorporated, so property inside them may fall under the town's rules. If a county has no general zoning, other rules such as subdivision, septic or floodplain permits can still apply.
The free parcel map helps
Our Boone County page links the official county parcel viewer, where you can find owner names, parcel numbers and acreage. For more on using the map itself, see our Boone County map guide.
Looking up a parcel's zoning in Boone County
Find the parcel on the official Boone 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.
Uses, setbacks and lot size
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.
Zoning and land purchases
Before you buy acreage for a house, barn or business, confirm the district allows it. Zoning is one piece. Septic suitability, access and flood zones can also stop a project.
From zoning approval to building
A use that zoning allows still usually needs a zoning or land-use permit, and often a separate building permit. Whether it's one counter or several depends on the county, so ask the office what applies to your project. 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. Farm uses get special treatment in many places, with exemptions for barns or other agricultural structures. Dividing land is normally a subdivision matter, with a plat that may need to be approved and recorded.
Where zoning is headed
Zoning follows a long-range plan in many places, and that plan hints at where growth and rezonings will be supported. 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. Plans are guidance, not law. The zoning ordinance and map are what apply today.
What to ask staff
Have the parcel number and a simple sketch or description of the project ready. Good questions: what's the district, is my use allowed, what are the setbacks, and do any overlays apply? If the answer matters for a purchase, ask for it in writing. Some offices issue a formal zoning verification letter.
Boone County at a glance
Boone County had about 26,590 residents in 2023, on about 570 square miles. The county seat is Boone, which is where the main county offices usually sit. Land just over the line in Dallas County, Greene County, and Hamilton County is recorded by those counties, not this one.
Common questions
Where can I check zoning in Boone County?
Start with the Zoning County Ordinance page on the county's official website (Zoning County Ordinance), 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.
