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

In unincorporated Garden County, a building permit is required before erecting, constructing, reconstructing, moving or structurally altering a building or other structure¹. Garden County collects no building-permit fee¹. The Zoning Administrator may make necessary inspections, but a complete inspection schedule could not be confirmed¹. Nebraska permits a state or generally conforming local building code; if a county fails to adopt an authorized code within two years after a state-code update, the state code applies except to construction on a farm or for farm purposes⁷. Ask Planning and Zoning which code and inspection stages apply to the proposed project⁵.

Start with Garden County Planning and Zoning at PO Box 350, 611 Main Street, Oshkosh, NE 69154, or call (308) 772-4464⁵. The Zoning Administrator receives applications to construct, alter, repair, occupy, use or change the use of land, buildings and structures, and may deny a permit that would allow a zoning violation¹. Ask the office to confirm the parcel’s jurisdiction and zoning district, then request the current application, required plans and submission method^1,5. Nebraska county building-permit authority excludes incorporated cities and villages and areas where a municipality exercises granted zoning jurisdiction, so confirm the correct building-permit office before applying⁸.

Garden County zoning governs unincorporated land; Oshkosh has its own zoning inside city limits^1,9. The Nebraska Onsite Wastewater Program remains the septic authority in Garden County². A-1 and A-2 non-farm development generally requires 40 acres, with an exception for smaller legal lots existing before adoption; RE requires 1 acre and RL requires 3,500 square feet¹. Setbacks and height rules also vary by district¹. A-1 and A-2 allow accessory single-family dwellings for people customarily employed at or engaged in farming or ranching on site; those provisions do not establish unrestricted accessory-dwelling use¹. Ask Planning and Zoning to identify the parcel’s district and classify the proposed dwelling⁵.

The Nebraska Onsite Wastewater Program administers septic tanks, holding tanks, small lagoons and other decentralized systems in Garden County². Every onsite system that is constructed, reconstructed, altered, modified or otherwise changed must be registered with the state². Most ordinary systems may proceed under Authorization by Rule, but systems handling at least 1,000 gallons per day, non-household wastewater or conditions outside that authorization require construction and operating permits and professionally prepared plans^3,10. Anyone performing onsite-wastewater inspection work must be certified unless the person is a licensed professional engineer or registered environmental health specialist, and a qualified professional must be present whenever the work is performed³. Off-grid living still requires compliant wastewater service². Only 15.9% of county soils lack severe limitations for a conventional drain field, so make wastewater feasibility a purchase condition¹¹.

Garden County's rule for permanent or long-term RV occupancy on private land could not be confirmed, so ask Planning and Zoning before relying on an RV as a residence⁵. A tiny home treated as a structure or residential use must comply with its zoning district and requires a building permit, but the county provisions do not separately define or regulate tiny homes¹. Garden County's single-family-dwelling definition includes code-compliant mobile homes, while mobile-home parks are conditional uses in specified districts and must follow the county's park standards and review process¹. Any wastewater-generating unit needs state-compliant sanitation even when off grid². Give Planning and Zoning the parcel number, unit type, foundation, utility plan and intended occupancy, and request a written classification⁵.

1. Ask Garden County Planning and Zoning to confirm county jurisdiction and identify the parcel's district on the official zoning map^1,5.

1. Confirm the allowed use, district lot size, setbacks and height rules before finalizing a site plan¹.

1. Apply to the Zoning Administrator before construction, reconstruction, moving or structural alteration, and ask which plans, code provisions and inspections apply^1,5.

1. Have a certified onsite-wastewater professional determine whether Authorization by Rule applies or state construction and operating permits are required^3,10.

1. Obtain the required floodplain development permit for a floodplain site; county conditional-use review also requires evidence that potential flood damage has been mitigated^1,6.

1. Obtain state written permission before constructing or reconstructing a driveway to a Nebraska state highway¹².

Confirm jurisdiction, zoning district and buildability with Garden County Planning and Zoning before closing^1,5. Compare the survey and proposed house site with the district's lot-size, setback and height rules, and confirm that any land division has an approved plat¹. Make the purchase contingent on wastewater feasibility because only 15.9% of county soils lack severe limitations for a conventional drain field¹¹. Check flood maps because floodplain development requires a permit; county review also restricts development that increases flooding potential and requires flood hazards to be identified in rezoning materials^1,6. Verify legal road access and obtain state permission before constructing or reconstructing an approach to a state highway¹². Nebraska management-area well permits depend on capacity and district rules; ask Planning and Zoning which natural resources district should review the proposed water source^5,13.
