Unincorporated Buffalo County, Nebraska requires zoning compliance for rural construction, but a general county construction-code permit could not be confirmed12. The county inspects setbacks and land uses, while Nebraska regulates onsite wastewater systems34. Before building, ask the Zoning Division for the parcel's district and required approvals5.

Do you need a building permit in Buffalo County, Nebraska?
For rural and unincorporated Buffalo County, plan on county zoning review before construction2. County staff inspect setbacks and land uses, but the available county materials do not establish a general countywide construction code or a full building-code inspection program31. Do not confuse the absence of a confirmed construction-code permit with permission to build anywhere: the parcel still must comply with its zoning district, permitted uses, lot standards and setbacks211. The published fee schedule lists a $200 zoning permit6. If the parcel is in a floodplain, a separate $150 development permit applies, and the county requires a separate permit for each building or structure126. Ask the Buffalo County Zoning Division what application is required for the exact parcel and project before ordering plans or site work5.
Who handles Buffalo County zoning and floodplain permits?
Buffalo County's Zoning Division is the first county contact for a rural building project because it works with the county's zoning map and code and reviews subdivision and special-use applications5. Call 308.236.1998, email [email protected], or write to PO Box 1270, Kearney, NE 688485. For floodplain questions, call the Buffalo County Floodplain Division at 308.236.1999 or email [email protected]; it uses the same mailing address13. The county describes its inspections as inspections of setbacks and land uses, not verified construction-code inspections3. Buffalo County's published schedule lists a $200 zoning permit and a $150 floodplain development permit6. A certificate-of-occupancy requirement could not be confirmed, so ask the Zoning Division what closes out the approval for the proposed use5.
Does Buffalo County have zoning?
Yes. Buffalo County zoning applies in the county's rural and unincorporated jurisdiction; incorporated places and areas where a city or village exercises zoning authority are different jurisdictions211. Lot size depends on the mapped district and proposal. The RC district generally has an 80-acre minimum, while AGR-1 and AGR-2 generally require 3 acres14. Shared community water and sewage can reduce the AGR minimum to 1 acre with state review, and an approved subdivision can reduce it to 70,000 square feet with state review and County Board approval14. Those figures are not a substitute for a parcel lookup because exceptions and district boundaries matter. Nebraska law also allows an agricultural category for qualifying farmsteads of at least 20 acres producing at least $1,000 in farm products annually, but the county board may still decide how residence buildings are treated15.
How do septic permits work in Buffalo County?
Nebraska, rather than Buffalo County, regulates onsite wastewater systems through the state onsite wastewater program47. Most Nebraska systems are constructed under Authorization by Rule without a separate construction permit, but large systems, non-domestic wastewater or site problems can trigger site-specific state review and permitting716. A new or changed system must still comply with Title 124 and be registered with the state16. Inspections must be performed or supervised by an appropriately certified professional, licensed engineer or registered environmental health specialist17. A dwelling that produces wastewater must connect to a public sewer or use a compliant onsite system18. Only about 41.1% of Buffalo County soils are rated without severe limitations for a conventional drain field, so obtain a parcel-specific site evaluation before treating an offer as final10.
Can you live in an RV or tiny home in Buffalo County?
Buffalo County's general rule for living in an RV on private land could not be confirmed, and the county materials reviewed do not establish a countywide tiny-home occupancy rule or minimum dwelling size. Ask the Zoning Division whether the proposed unit is a permitted dwelling in the parcel's district and what zoning approval, setbacks and utility arrangements apply511. Floodplain parcels have a specific RV rule: an RV must be on site fewer than 180 consecutive days, be fully licensed and ready for highway use, or satisfy the applicable manufactured-home permit, elevation and anchoring requirements8. That floodplain rule does not answer year-round occupancy elsewhere. Any occupied dwelling that generates wastewater must connect to public sewer or have a Title 124-compliant onsite wastewater system18. A manufactured home also cannot be prohibited solely because it is manufactured, although lawful, uniformly applied siting and design standards may still apply11.
Building a home in Buffalo County: the steps, in order
- Ask the Zoning Division to identify the parcel's zoning district, allowed residential use, lot standards and setbacks514.
- Confirm legal road access; a new, moved or altered driveway onto a state highway requires a state permit19.
- Ask the Floodplain Division whether the building site is regulated; floodplain development requires a permit, and Buffalo County requires a separate permit for each structure1312.
- Submit the county zoning application and budget the published $200 fee6.
- Have a Nebraska-qualified onsite wastewater professional determine whether Authorization by Rule is sufficient or a state permit is needed, then ensure the system is registered1617.
- If doing your own work, remember that Nebraska's own-property contractor-registration exemption does not waive zoning, floodplain or wastewater approvals9.
What should you check before buying land in Buffalo County?
Start with the zoning map and exact district: Buffalo County's minimum lot standards range materially by district, and special approvals or exceptions can change the result145. Check the proposed house site against floodplain mapping because regulated development needs a permit and may face elevation or engineering conditions12. Have septic feasibility evaluated on the actual site; only about 41.1% of county soils are rated without severe limitations for a conventional drain field10. Confirm legal road access and ask the correct road authority before assuming an existing field entrance can become a residential driveway; state-highway approaches require a permit19. Buffalo County averages about 25.9 inches of precipitation annually and severe drought has occurred in about 18.7% of years, so investigate the water source and well feasibility rather than relying on rainfall2021. The effective property-tax rate is about 1.5%, and the median annual bill is about $3,4352223.
Watch-outs
- A missing construction-code permit is not a zoning exemption: Buffalo County still regulates rural land use, districts, lots and setbacks12.
- RC, AGR-1 and AGR-2 parcels do not share one minimum lot size, so identify the district before relying on acreage alone14.
- The floodplain RV rule is not a general answer for living in an RV elsewhere in Buffalo County; ask the Zoning Division about private-land occupancy85.
- Buffalo County's private-well permit or registration requirement could not be confirmed; ask the Zoning Division which state or local water authority serves the parcel5.
