Unincorporated Johnson County, Nebraska requires a zoning permit before a new structure is built, moved, added to or structurally altered; this is zoning approval, not a separate building-code permit1. The Johnson County Zoning Administrator issues those zoning permits for the rural and unincorporated planning jurisdiction, not for every incorporated community1,2. Septic permits and registration for every address in the county, town or country, run through Nebraska's Onsite Wastewater Program3.
Do you need a building permit in Johnson County, Nebraska?
In Johnson County's rural and unincorporated planning jurisdiction, a zoning permit must be issued before a structure is built, moved, added to or structurally altered.
In Johnson County's rural and unincorporated planning jurisdiction, a zoning permit must be issued before a structure is built, moved, added to or structurally altered1,2. The county material establishes zoning review, not a separate building-code permit1. The Zoning Administrator may inspect land uses and building locations for zoning compliance, but that authority is not a general structural building-inspection program2.
We could not confirm whether Johnson County adopted a local construction code, so ask the Zoning Administrator what code and approvals apply to the project1. Nebraska's state building code applies where a county, city or village has not adopted an authorized local code after the statutory update period, except to construction on a farm or for farm purposes7. Agricultural structures are exempt from county height limits, but not categorically from zoning permits2.
Who issues building and zoning permits in Johnson County, Nebraska?
The Johnson County Zoning Administrator is the first call for county zoning and building-permit questions.
The Johnson County Zoning Administrator is the first call for county zoning and building-permit questions1,2. A zoning-permit application requires a plot plan showing structures, lot lines, proposed uses, building lines, parking, site improvements and other information the administrator requires2. The Zoning Administrator must approve or disapprove an application within 30 days; a written appeal to the Board of Adjustment is due within 10 days after the determination is filed2.
The zoning fee schedule is posted in the Zoning Administrator's office and may be changed by the County Board, but current amounts were not confirmed2. Contact the office at 402-335-7065 or mdavison@tecumsehne.com, or use 1369 Eastridge Drive, Tecumseh, NE 684501.
Does Johnson County, Nebraska have zoning?
Johnson County zoning applies within the rural and unincorporated planning jurisdiction shown on official zoning maps, not inside every incorporated community.
Johnson County zoning applies within the rural and unincorporated planning jurisdiction shown on official zoning maps, not inside every incorporated community2. Lot sizes, setbacks and heights vary by district2. In the AGR Agricultural Residential District, a single-family dwelling generally requires a 3-acre lot adjoining an improved all-weather county road above a minimum-maintenance road2. Under stated special-use and wastewater or shared-utility conditions, some parcels may be reduced to 1 acre2.
The AGR front yard is 58 feet from the road center, with a 15-foot rear yard and 10-foot side yard subject to road-frontage alternatives2. The AGR maximum for ordinary structures is 35 feet, while nonresidential and agricultural exceptions apply2. Have the Zoning Administrator identify the parcel's jurisdiction, mapped district and exact standards before siting improvements1.
How do septic permits work in Johnson County, Nebraska?
The Nebraska DWEE Onsite Wastewater Program administers Title 124 in Johnson County, while any local requirements are separate and additional.
The Nebraska DWEE Onsite Wastewater Program administers Title 124 in Johnson County, while any local requirements are separate and additional3. A state permit is required for systems handling at least 1,000 gallons per day, non-household wastewater or systems outside Authorization by Rule; most other systems may proceed under Authorization by Rule if they meet state requirements and are registered4. Permitted systems require engineer-prepared plans, a construction permit before building and an operating permit before use4.
State approval is required before developing an area with onsite systems on lots smaller than 3 acres, and a qualified professional must prepare the layout4. The mapped share of Johnson County soils without severe limitations for a conventional drain field is 0%, so arrange a certified site evaluation before fixing a homesite8. Call Nebraska DWEE at (402) 471-4285 for registration and permit guidance6.
Can you live in an RV or tiny home in Johnson County, Nebraska?
Johnson County's rules treat premises with at least 2 camping units as a campground, and campgrounds in the AGR Agricultural Residential District require a special-use permit.
Johnson County's rules treat premises with at least 2 camping units as a campground, and campgrounds in the AGR Agricultural Residential District require a special-use permit2. That rule does not establish a general right to long-term residential RV occupancy on private land, and we could not confirm such a right or a specific county rule for tiny-home occupancy. Give the Zoning Administrator the unit type, number of units, proposed utilities, occupancy duration and parcel before buying or moving onto the site1,2.
Off-grid does not mean sanitation-free: any dwelling or non-dwelling generating wastewater needs a state-compliant onsite treatment system or a connection to sewer or other wastewater works6. A manufactured home outside a mobile-home park must carry the required Nebraska seal and still comply with its zoning district and permit requirements2.
What are the steps to build a home in Johnson County, Nebraska?
Ask the Johnson County Zoning Administrator to confirm county jurisdiction, the mapped district, permitted use, lot size, setbacks, height limit and road qualification.
- Ask the Johnson County Zoning Administrator to confirm county jurisdiction, the mapped district, permitted use, lot size, setbacks, height limit and road qualification1,2.
- Prepare the plot plan and supporting documents for zoning review, then confirm the current fee with the office2.

What should you check before buying land in Johnson County, Nebraska?
Start with a jurisdiction and zoning review: confirm the parcel's mapped district, allowed residence type, lot size, setbacks, height limit and legal road access with the Johnson County Zoning Administrator.
Start with a jurisdiction and zoning review: confirm the parcel's mapped district, allowed residence type, lot size, setbacks, height limit and legal road access with the Johnson County Zoning Administrator1,2. For an AGR homesite, verify the 3-acre standard and adjacency to an improved all-weather county road above minimum maintenance2. Check flood mapping before choosing a pad: floodplain development requires a permit, and the county ordinance restricts structures within the high-water mark in designated flood-hazard areas unless the base or footings are at least 1 foot above it2,11.
Budget for site-specific wastewater work: 0% of mapped county soils are rated without severe limitations for conventional drain fields8. Confirm the water source and ask the appropriate water authority about well approvals because we could not confirm a general Johnson County well-permit rule. The effective property-tax rate is about 1.5%, and the median annual bill is about $1,993; verify the specific parcel with the assessor8.
Watch-outs
- Do not treat the agricultural height exemption as a blanket permit exemption; new structures in the county planning jurisdiction still require zoning permits1,2.
- Conventional septic conditions may be difficult because 0% of mapped soils are rated without severe drain-field limitations; use a properly certified onsite professional early8,9.
- Long-term private-land RV living and tiny-home occupancy remain unconfirmed, while a campground in the AGR district requires special-use approval; ask the Johnson County Zoning Administrator before committing to a plan1,2.
- An off-grid building that generates wastewater still needs a state-compliant onsite system or connection to sewer or other wastewater works6.
