Red Willow County, Nebraska requires county zoning approval for building projects, and the permit form calls the approval a zoning permit12. The county has zoning, but we could not confirm a separate countywide building-permit rule or the county's adoption of a building code3. Nebraska's statewide onsite wastewater program governs septic systems4.

Do you need a building permit in Red Willow County, Nebraska?
Red Willow County requires county approval for building projects through its Planning and Zoning office, and the county application is titled a zoning permit12. The application covers a structure that will be erected, moved or enlarged and asks for the proposed use, dimensions, construction type, project cost, septic need and floodplain status2. The county has not confirmed a separate countywide building-permit requirement or adoption of a local building code, so ask Planning and Zoning which structural code, trade permits and inspections apply to the particular project8. Nebraska's state building code can apply by default where a local jurisdiction has not timely adopted an authorized local code, with an exception for construction on a farm or for farm purposes11. The county permit allows the Zoning Administrator or authorized personnel to enter the property for an inspection tied to the application; that does not establish a general building-code inspection program12.
Who handles Red Willow County building permits and zoning?
Red Willow County Planning and Zoning is the first contact for the county zoning permit and parcel-specific land-use questions8. Reach the office at 308-234-6456 or [email protected], or visit 1111 Central Avenue in Kearney8. Before drawing final plans, give the office the legal description and property address so it can identify the zoning district and its setbacks5. The county's published application requires the project description and a site plan showing the proposed structure, lot lines, existing buildings, adjoining roads, and the septic tank and drain field2. The zoning-permit fee is $100, payable to the Red Willow County Treasurer6. The application also states that the approval remains valid for 2 years2. No certificate-of-occupancy rule was confirmed, so ask the office what final sign-off is needed before occupying a new dwelling8.
Does Red Willow County have zoning?
Yes. Red Willow County has adopted zoning and publishes an official zoning map313. The map identifies General Agriculture, Transitional Agriculture, Flood Hazard Overlay, Wellhead Protection Overlay, and airport-related zones and overlays13. Nebraska county zoning authority generally applies outside incorporated cities and villages and outside unincorporated territory where a city or village is exercising granted or ceded zoning jurisdiction14. Setbacks differ by zoning district, so there is no single setback figure to apply across every county parcel5. Take the legal description and address to Planning and Zoning for the controlling district and dimensional standards58. We could not confirm county rules for minimum lot size, lot coverage, building height, accessory dwellings or a general minimum home size. Nebraska law permits a county board to impose specified standards on manufactured homes, but that authority does not prove Red Willow County adopted every permitted standard15.
How do septic permits work in Red Willow County?
The Nebraska Department of Water, Energy, and Environment administers statewide onsite-wastewater requirements in Red Willow County under Title 124416. Most Nebraska onsite wastewater systems use Authorization by Rule rather than a construction permit, but systems involving large size, non-domestic waste or siting issues can require a state permit7. New or changed systems must also be registered with the state7. Reach the Onsite Wastewater Program at (402) 471-4285 or [email protected]17. Septic inspection must be performed or supervised by a certified professional or another professional authorized by Nebraska law18. About 63.2% of Red Willow County soils lack severe limitations for a conventional septic drain field, which makes a parcel-specific soil and site evaluation more useful than the countywide average19. A dwelling that generates wastewater must use a Title 124-compliant onsite system or connect to public sewer or other wastewater works20.
Can you live in an RV or tiny home in Red Willow County?
We could not confirm a Red Willow County rule that specifically allows or prohibits long-term RV occupancy, temporary camping on private land or tiny-home occupancy. Because Red Willow County has zoning, ask Planning and Zoning how the parcel's district classifies an RV, a tiny house on wheels or a foundation-built small home before buying or placing one38. Nebraska's public-property camping restriction covers designated sites along public highways, roadside areas, parks and similar public property; it does not answer whether an owner may occupy an RV on private land21. We also could not confirm a countywide minimum dwelling size. Nebraska law lets a county board impose certain manufactured-home standards, including a minimum floor-area standard, but the authority is discretionary and is not a statewide minimum for every dwelling15. Any occupied dwelling that generates wastewater still needs a compliant onsite system or a connection to public wastewater works20.
Building a home in Red Willow County: the steps in order
- Ask Red Willow County Planning and Zoning to confirm the parcel's jurisdiction, zoning district, allowed residential use and setbacks358.
- Have a certified onsite professional evaluate the wastewater site and determine whether Authorization by Rule or a state permit applies718.
- Prepare the county zoning-permit application and site plan, including structure dimensions, lot-line distances, existing buildings, road location, and septic components2.
- If the structure is in a floodplain, obtain the signed floodplain development permit and attach it to the zoning application1022.
- If access connects to a state highway, obtain the state permit before constructing, relocating or altering the driveway23.
What should you check before buying land in Red Willow County?
Confirm jurisdiction, zoning district, allowed use and setbacks before closing, especially near a city or village where municipal jurisdiction may displace county zoning authority145. Check floodplain status before placing a home, driveway or fill because all development in a Nebraska floodplain requires a permit, and the county application requires a signed floodplain development permit for a structure in a floodplain2410. The Floodplain Administrator can be reached at 308-234-6456 or [email protected]22. Evaluate water supply and septic soils early: annual precipitation averages about 21.8 inches, severe drought has occurred in about 25.8% of years, and about 63.2% of soils lack severe limits for a conventional drain field252619. A private-well permit rule was not confirmed, so ask the applicable natural resources district and the state water-well program before drilling. For budgeting, the effective property-tax rate is about 1.3%, with a median annual property-tax bill around $1,8112728.
Watch-outs
- Do not mistake the county zoning permit for proof that no structural code or trade permit applies; Red Willow County's local building-code adoption was not confirmed111.
- A structure in a floodplain needs a signed floodplain development permit attached to the county zoning application10.
- Private-land RV occupancy, tiny-home occupancy, minimum dwelling size and private-well permitting remain unconfirmed; ask Planning and Zoning and the applicable state or natural-resources-district office before relying on them38.
