Building permits, zoning and land rules in Kimball County, Nebraska

Unincorporated Kimball County requires zoning approval before erecting, constructing or altering a nonfarm building or structure in the county zoning area¹. The zoning resolution expressly says its permits and certificates concern land-use compliance and do not create a building, plumbing, electrical or other construction code¹. Nebraska's state building code applies by default where a county has not adopted an authorized local code within the statutory update period, except for construction on a farm or for farm purposes¹⁰. Because we could not confirm a separate Kimball County residential building-code permit or inspection program, ask Planning and Zoning which zoning approval and state-code path apply before ordering plans³. Buildings genuinely used for agricultural purposes have a conditional county zoning exemption, but that exemption does not settle every other requirement¹.

Kimball County Planning and Zoning is the first stop for a nonfarm project in the unincorporated county zoning area¹. The Zoning Administrator helps applicants complete the appropriate application, and the Board of Commissioners establishes zoning fees³. Contact the office at (308) 235-2235 or Kcpz71@actcom.net, or visit 3475 Rd 37 W, Kimball, NE 69145³. Published fees include $250 for a conditional-use application, while an after-the-fact application costs $1,000 if the Board agrees to issue it; these are zoning and subdivision fees, not a general residential building-code permit schedule¹¹. We could not confirm a general building-inspection schedule or county certificate-of-occupancy requirement, so ask what construction documents, inspections and final approvals apply. Projects within municipal zoning jurisdiction should go to the municipality¹.

Yes. Kimball County zoning applies to unincorporated territory outside municipal zoning jurisdiction¹. For nonfarm housing in the A-1, A-2 and RE districts, the minimum lot size is 10 acres¹. The A-1 and A-2 minimum setback is 150 feet along Highway 71 south of Kimball and 50 feet elsewhere; the RE minimum setback is 50 feet, with district-specific side and rear yard rules¹. The official zoning map is maintained at the Kimball County Courthouse, so confirm the parcel's mapped district and any overlay before relying on those measurements¹. Subdivision is also regulated: a subdivision lot cannot be sold or built on until the final plat is approved and recorded¹. A building also needs public or approved private road frontage or a recorded permanent access easement at least 20 feet wide¹.

Onsite wastewater systems in Kimball County are regulated by the Nebraska Department of Water, Energy and Environment under statewide Title 124, using state-certified professionals rather than a county septic department². Most Nebraska onsite systems are built under Authorization by Rule without a construction permit, but every constructed or modified system must be registered with the state^4,5. A state permit is required when a system handles at least 1,000 gallons per day, accepts non-household wastewater or falls outside Authorization by Rule; the plans must be prepared by a professional engineer, and the listed application fee is $450⁴. Only 25.5% of Kimball County soils rate as free of severe limitations for a conventional drain field, so arrange a certified site and soil evaluation early^12,13. Contact the DWEE Onsite Section at (402) 471-4285 for registration, certification and permit questions¹⁴.

We could not confirm a complete Kimball County rule for long-term RV occupancy, temporary camping on private property or tiny-home occupancy. Because unincorporated Kimball County is zoned, ask Planning and Zoning whether the proposed dwelling type and occupancy are allowed in the parcel's district before buying or moving a unit onto the land^1,3. Nebraska's restriction on camping along public highways, roadside areas and public property does not answer whether someone may occupy an RV on private land¹⁵. State law lets a county impose certain standards on manufactured homes, including a discretionary minimum of 900 square feet, but that authority does not prove that Kimball County applies that minimum to a particular home¹⁶. Any dwelling that generates wastewater must use a compliant onsite system or connect to an approved wastewater works¹⁷.

1. Confirm whether the parcel is under Kimball County zoning or a municipality's zoning jurisdiction¹.

1. Ask Planning and Zoning for the mapped district, allowed residential use, overlays and application^1,3.

1. Check the district standard: nonfarm housing in A-1, A-2 and RE requires a 10-acre lot, and setbacks vary by district and road frontage¹.

1. Confirm legal access; the lot must front an approved road or have a recorded permanent access easement at least 20 feet wide¹.

1. Have a state-certified onsite professional evaluate and register the wastewater system or obtain any required state permit⁴.

1. Obtain county zoning approval and confirm the applicable state building-code path before construction^1,10.

Start with jurisdiction, mapped zoning district and legal access: county rules apply only outside municipal zoning jurisdiction, district standards vary, and development needs approved road frontage or a recorded access easement¹. For nonfarm housing in A-1, A-2 and RE, verify that the parcel can satisfy the 10-acre minimum and applicable setbacks before closing¹. Make septic feasibility a purchase contingency because only 25.5% of county soils rate as free of severe limitations for a conventional drain field¹². We could not confirm the applicable private-well permit rule, so ask the well contractor and relevant state water authority before drilling. Kimball County averages 16.6 inches of precipitation annually, and severe drought occurs in 20.2% of years¹². The effective property-tax rate is about 1.7%, with a median annual bill of $1,905¹².
