Do you need a building permit in Buffalo County, Nebraska?
In rural and unincorporated Buffalo County, a county zoning permit is required before a structure or use is erected, moved, added to, demolished or structurally altered.
In rural and unincorporated Buffalo County, a county zoning permit is required before a structure or use is erected, moved, added to, demolished or structurally altered1. The zoning permit fee is $2003. County staff inspect setbacks and land uses, but we could not confirm a general county building-code inspection program8. Agricultural-purpose buildings do not need the zoning permit when they are on a farmstead of at least 20 acres that produces at least $1,000 in farm products annually1. Floodplain construction, substantial improvements and manufactured-home placement in mapped Zone A need a separate development permit, whose published fee is $1503,5. Ask the Buffalo County Zoning Division to identify every approval for the parcel before starting work9.
Who handles Buffalo County zoning and floodplain permits?
The Buffalo County Zoning Division is the first county contact for rural construction because it works with the zoning map and code and reviews subdivision and special-use applications.
The Buffalo County Zoning Division is the first county contact for rural construction because it works with the zoning map and code and reviews subdivision and special-use applications9. Call 308.236.1998, email zoning@buffalocounty.ne.gov, or write to PO Box 1270, Kearney, NE 688489. A zoning application must include a plot plan showing structures, additions, parking, improvements, lot lines, proposed uses and building lines1. The Zoning Administrator must approve or disapprove a complete application within 30 days, with floodplain review in the same period1. For mapped floodplain questions, call the Buffalo County Floodplain Division at 308.236.1999 or email floodplain@buffalocounty.ne.gov9. Buffalo County publishes its zoning and floodplain fee schedule, but a certificate-of-occupancy requirement could not be confirmed; ask the Zoning Division what final signoff applies9.
Does Buffalo County have zoning?
Yes.
Yes. Buffalo County zoning covers the county's rural and unincorporated planning jurisdiction, while incorporated municipalities may apply separate rules1. The county publishes AG, RC, AGR-1, AGR-2, Commercial and Industrial districts, and allowed uses, height limits and site standards vary by district1. Do not carry the Commercial district's 40,000-square-foot lot area or its setbacks over to a rural residential parcel; those verified figures are district-specific1. An accessory dwelling unit in AGR-2 requires a special-use permit7. Subdivision land within county jurisdiction requires an approved plat, subject to stated exemptions and jurisdictional limits10. Ask the Zoning Division for the parcel's mapped district, permitted use, lot standard, setbacks and height rule before designing a home9.
How do septic permits work in Buffalo County?
Nebraska's onsite wastewater program administers septic rules in Buffalo County, subject to any additional local requirements.
Nebraska's onsite wastewater program administers septic rules in Buffalo County, subject to any additional local requirements2. Qualifying systems use a general permit, while a system outside that coverage needs a state construction permit before construction, reconstruction, alteration, modification or nonexempt repair4,11. Anyone performing percolation testing, installation, repair, pumping or inspection must hold the required state certification unless the person is a licensed professional engineer or registered environmental health specialist12. That professional-qualification rule does not establish routine periodic inspections for every home12. A dwelling that generates wastewater must connect to public sewer or other wastewater works, or use an onsite system compliant with Title 12413. About 41.1% of Buffalo County soils are rated without severe limitations for a conventional drain field, so make septic feasibility a parcel-level contingency14.
Can you live in an RV or tiny home in Buffalo County?
A general Buffalo County rule for living in an RV on private land could not be confirmed, so ask the Zoning Division whether residential occupancy is allowed in the parcel's district.
A general Buffalo County rule for living in an RV on private land could not be confirmed, so ask the Zoning Division whether residential occupancy is allowed in the parcel's district9. In mapped floodplain areas, an RV must be present fewer than 180 consecutive days, remain fully licensed and highway-ready, or comply with the applicable manufactured-home permit, elevation and anchoring rules5. That floodplain rule is not permission for year-round RV living elsewhere. Campgrounds in AGR-1 are special uses and must abut and have access to a paved road, but that rule does not settle personal camping on a private parcel1. Buffalo County's materials do not provide a countywide answer for tiny-home occupancy or minimum dwelling size; ask the Zoning Division how the proposed unit will be classified9. Any occupied unit generating wastewater must use compliant onsite treatment or connect to an approved wastewater system13.
Building a home in Buffalo County: the steps, in order
Ask the Zoning Division for the parcel's district, allowed residential use, lot standard, setbacks and height limits.
- Ask the Zoning Division for the parcel's district, allowed residential use, lot standard, setbacks and height limits1,9.
- If division of land is involved, determine whether the county subdivision process and plat approval apply10.
- Confirm access: subdivision landowners need a County Highway Department driveway permit, and the department checks drainage and culvert size15.
- Ask the Floodplain Division whether mapped floodplain rules and a separate development permit apply5,9.
- Prepare the plot plan and submit the zoning application with the $200 fee1,3.
- Have a state-qualified onsite wastewater professional establish whether general-permit coverage or a state construction permit applies4,12.
- Remember that the owner-property contractor-registration exemption does not waive county zoning or wastewater requirements1,6.
What should you check before buying land in Buffalo County?
Start with the official zoning district because uses, site standards and height rules vary across Buffalo County's six districts.
Start with the official zoning district because uses, site standards and height rules vary across Buffalo County's six districts1. If you plan to split land, confirm whether county plat approval applies before assuming a new parcel is buildable10. Check the proposed building site against floodplain mapping because regulated development requires a separate permit5. Verify driveway access and budget for any culvert the County Highway Department requires the owner to buy and install15. Test septic feasibility on the actual homesite because only about 41.1% of county soils are rated without severe limitations for a conventional drain field14. Buffalo County averages about 25.9 inches of precipitation annually, while severe drought occurred in about 18.7% of years, so confirm the parcel's water source and ask the applicable natural resources district whether a well permit is required14,16.
Watch-outs
- A zoning permit is required for covered work even though a general county construction-code permit could not be confirmed1,8.
- Lot size, setbacks and height are district-specific; do not apply the verified Commercial district figures to an agricultural or residential parcel1.
- The floodplain RV rule does not answer whether year-round RV occupancy is allowed elsewhere in Buffalo County; ask the Zoning Division5,9.
- A driveway permit is established for subdivision access to county roads, but a countywide rule for every existing parcel could not be confirmed15.
