Who handles zoning in Story County
The county website lists a Planning & Zoning Commission page at Planning & Zoning Commission. It's an office page rather than a map, so use it for contacts, ordinances and applications. It was free to open with no account when we checked on October 13, 2026.
Check who has jurisdiction first
First figure out whether the parcel is inside a municipality, because towns typically zone their own territory. Parcels inside Ames, Cambridge, and Collins 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.
Start from the parcel map
Our Story County page links the official county parcel viewer, where you can find owner names, parcel numbers and acreage. We cover the map in more depth in this Story County guide.
Looking up a parcel's zoning in Story County
Start by finding the lot on the Story County parcel map so you have a parcel ID. Next, match that parcel to a district on the zoning map, or email the office with the parcel number. The letters and numbers mean little until you read the matching section of the ordinance.
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
Before you buy acreage for a house, barn or business, confirm the district allows it. Septic, driveway and floodplain permits are separate from zoning but just as important.
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. Skipping permits can cause problems at resale, when buyers and lenders ask for records.
Beyond the base district
Overlay districts add rules for floodplains, watersheds, airports or corridors on top of the base zoning. Farm uses get special treatment in many places, with exemptions for barns or other agricultural structures. Splitting a parcel usually falls under subdivision rules, which may require a surveyed plat to be recorded.
Long-range plans
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. For a sale or a loan, a written zoning verification beats a phone call.

Quick answers
Where can I check zoning in Story County?
Start with the Planning & Zoning Commission page on the county's official website (Planning & Zoning Commission), 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.
