Unincorporated Hayes County, Nebraska requires a county zoning permit before a structure with a permanent foundation is built, moved, enlarged or structurally altered1. Hayes County Planning & Zoning sets zoning there, while septic permits come from the state Department of Water, Energy, and Environment, not the county2. Land inside a municipality or its legally established planning area falls outside the county zoning resolution3.

Do you need a building permit in Hayes County, Nebraska?
Hayes County requires a zoning permit before a structure with a permanent foundation is erected, moved, enlarged or structurally altered in the county zoning jurisdiction1. This county approval is a zoning permit, not evidence of a separate county building-code permit13. Nebraska's state building code applies in a county that has not adopted a local building or construction code within the statutory period, although that fallback does not apply to construction on a farm or for farm purposes14. Ask Hayes County Planning & Zoning which code path applies to the project before finalizing plans15. The Zoning Administrator inspects for compliance with the zoning resolution, and covered premises need a certificate of zoning compliance before occupancy1617. Nonresidential farm buildings are exempt from the county zoning resolution, but nonagricultural uses and associated waste-handling uses are not18.
Who handles Hayes County building permits and zoning?
Hayes County Planning & Zoning issues the county zoning permit and answers parcel-specific land-use questions115. Reach the office at (308) 286-3413 or zoning@hayescounty.ne.gov, or visit 505 Troth Street, Hayes Center, NE 6903215. The posted office hours are 8:00 a.m. to 4:00 p.m.15. A zoning-permit application uses the county form and plot plan; the requested details can include uses, water supply, sewage disposal, erosion control, soil conditions and permeability19. Approved work must begin within 90 calendar days and be completed within two years or the zoning permit expires13. The county publishes a fee schedule, and applicable fees must be paid before action on an application or permit20. Hayes County's inspections establish zoning compliance, so ask the office separately how the state building-code framework applies to the project1614. Inside a municipality or its legally established planning and zoning area, the county zoning resolution does not apply, so ask that town about zoning permits3. Septic permits and well registration stay with state offices at any address in Hayes County, town or country221.
Does Hayes County have zoning?
Yes. Hayes County zoning governs unincorporated land outside municipal limits and legally established municipal planning and zoning areas22. The county has AG-G General Agricultural and AG-T Transitional Agricultural districts, and the official zoning map controls a parcel's current district23. In AG-G, homes have a 58-foot front setback, 10-foot side setbacks and a 10-foot rear setback; AG-T keeps the 58-foot front and 10-foot rear setbacks but uses a 5-foot side setback2425. Buildings designed for human habitation in either district are limited to 35 feet in height2627. A single-family, manufactured or modular home needs two acres in AG-G; in AG-T, it needs two acres with septic or 10,000 square feet with public or semi-public sewer1011. More intensive residential subdivision can require conditional-use approval28.
How do septic permits work in Hayes County?
The Nebraska Department of Water, Energy, and Environment administers onsite-wastewater requirements in Hayes County2. Reach the Onsite Wastewater Program at (402) 471-4285 or DWEE.onsite@nebraska.gov29. Most systems proceed under Authorization by Rule, but a state permit is required for systems handling 1,000 gallons per day or more, non-household wastewater, or systems outside that authorization6. A wastewater-generating dwelling must use a state-compliant onsite system or connect to public sewer or other wastewater works30. Off-grid sanitation can use a compliant onsite system, but cesspools, dry wells, leaching pits and seepage pits are prohibited31. A development proposing onsite systems on lots smaller than three acres needs state review before development, with a $450 application fee per lot32. About 47.9% of Hayes County soils lack severe limitations for a conventional drain field, so evaluate the septic area before fixing the house location33.
Can you live in an RV or tiny home on land in Hayes County?
Hayes County treats campgrounds as conditional uses in AG-G, and a campground includes premises where two or more camping units are placed for camping7. Campgrounds in AG-T also require conditional-use approval34. Those provisions do not answer whether one RV may serve as a residence or temporary camp on an individual parcel, so obtain a written parcel-specific answer from Hayes County Planning & Zoning15. A Nebraska tiny house may be classified as a manufactured home, modular unit or recreational vehicle; that classification does not itself authorize occupancy under local zoning35. Hayes County allows manufactured and modular homes as single-family dwellings in AG-G and AG-T subject to district conditions, including lot size and qualifying road access3637. We could not confirm a numeric county minimum dwelling size, so ask Planning & Zoning before buying or placing a small unit15.
How do you build a home in Hayes County, Nebraska, step by step?
- Ask Hayes County Planning & Zoning to confirm county or municipal jurisdiction and identify the parcel's zoning district3815.
- Confirm the use, lot size, setbacks, height and public-road access requirements before preparing the plot plan39404137.
- Obtain the county zoning permit before work on a structure with a permanent foundation, and ask which state or local building-code path applies1314.
- Have a qualified onsite professional determine the wastewater approval route before construction642.
- Obtain state approval for a new, relocated or altered driveway connecting to a state highway43.
What should you check before buying land in Hayes County?
Confirm jurisdiction and the official zoning-map district first, because county zoning excludes municipal limits and legally established municipal planning areas4523. Verify legal road access: AG-G and AG-T dwellings generally need access to an existing public road other than a minimum-maintenance or unimproved road, and Hayes County does not promise to improve such a road37. Check the mapped floodplain because all development in a Nebraska floodplain requires a permit46. Test the septic area early: only about 47.9% of county soils lack severe limitations for a conventional drain field33. Well registration is handled by the state and costs $240 for wells pumping 50 gallons per minute or less21. A single well pumping more than 50 gallons per minute may need Natural Resources District approval before registration12. For budgeting, the effective property-tax rate is about 1.3%, with a median annual bill of $1,4294748.
Watch-outs
- A Hayes County zoning permit is not a substitute for applicable building-code compliance; Nebraska's state code supplies the fallback where no timely local code was adopted, subject to the farm-construction exception1314.
- Private-land occupancy in one RV and tiny-home occupancy were not confirmed; campground rules do not supply that answer, so ask Hayes County Planning & Zoning715.
- An owner-builder exemption from contractor registration does not waive zoning permits, building-code duties, septic rules or other approvals89.
