Do you need a building permit in Cass County, Nebraska?

Yes. Cass County requires an approved permit for most construction activities, land-use changes and structural alterations within its jurisdiction1. Cass County administers the 2012 building, residential, plumbing, mechanical and fuel-gas codes and the 2018 energy code, while the Nebraska State Electrical Division handles the 2023 electrical code, permits and inspections15. Required field inspections apply to construction subject to county codes and zoning; electrical inspections come from the state3. A final inspection and certificate of occupancy are required before occupancy4. An owner working on the owner's own property is exempt from Cass County contractor registration, but still needs the applicable building permit10. A qualifying agricultural building has a separate exemption tied to agricultural use on a farmstead of at least 20 acres producing at least $1,000 in farm products annually14.

Who issues building and land-use permits in Cass County?

Cass County Planning & Zoning is the main permit and inspection office for rural Cass County12. The department administers building and inspection applications, floodplain development permits, county-road access permits, zoning changes, conditional uses, subdivision plats and other land-use changes1216. Cass County also provides building-permit and inspection services by interlocal agreement for Alvo, Avoca, Cedar Creek, Elmwood, Greenwood, Manley, Murray, Nehawka, South Bend, Union and Weeping Water12. Municipal zoning and extraterritorial jurisdiction can apply separately, so confirm the parcel's governing authority before applying17. Reach Planning & Zoning at (402) 296-9359 or zoning@casscountyne.gov12. Published county fees include $250 for floodplain review and $500 for grading one through 10 acres; all listed permit fees are non-refundable18.

Does Cass County have zoning?

Cass County zoning serves rural and unincorporated land in the county's jurisdiction19. The county publishes an official zoning map and eight districts, and the use matrix distinguishes permitted, conditional, administrative and prohibited uses720. Minimum lot area varies by district and use; the district schedule ranges from 7,200 square feet for one listed category to 40 acres for others21. Building-height limits, setbacks and lot coverage depend on the applicable zoning regulation and property circumstances222324. Short-term rentals require a conditional-use permit in the Residential District, so do not assume a lodging-tax registration settles zoning approval25. Ask Planning & Zoning to identify the parcel's authority, district, allowed use and dimensional standards before choosing a building site12.

How do septic permits work in Cass County?

Nebraska Title 124 governs onsite wastewater systems in Cass County, and a dwelling or other facility generating wastewater must use a compliant onsite system or connect to wastewater works5. A system not covered by a general permit needs a state construction permit before construction; the state must approve its design, and the application carries a fee9. Cass County's residential process requires inspection after the tank and laterals are set but before they are covered, plus a septic and lateral site plan and, when applicable, a percolation test6. Periodic tank inspection must use an authorized pumper, professional engineer or registered environmental health specialist26. Only about 5.9% of Cass County soils are rated without severe limits for a conventional drain field, so make septic feasibility an early purchase contingency27. Cesspools, dry wells, leaching pits and seepage pits are prohibited28. Contact Nebraska DWEE at (402) 471-4285 or DWEE.onsite@nebraska.gov29.

Can you live in an RV or tiny home on land in Cass County?

Cass County prohibits permanent residence in an RV park or campground except for the owner, manager and permanent maintenance personnel; that rule does not answer occupancy on other private land11. Ask Planning & Zoning about private-parcel RV occupancy and temporary camping before moving in because a broader county rule could not be confirmed12. Nebraska classifies a tiny house as a manufactured home, modular unit or recreational vehicle depending on construction; a park model is temporary living quarters and cannot be permanently affixed as a permanent dwelling13. Local zoning and building rules still determine placement and occupancy13. Any occupied dwelling producing wastewater needs a compliant onsite system or connection to wastewater works30. Cass County also requires its approval and an issued building permit before utility connections to a proposed building31.

Building a home in Cass County: the steps, in order

  1. Confirm whether county, village or municipal extraterritorial authority governs the parcel17.
  2. Ask Planning & Zoning for the district, allowed use, lot area, setbacks and height standard202122.
  3. Download the appropriate application and submit it with detailed site plans to Planning & Zoning32.
  4. Check the floodplain overlay because Cass County publishes a floodplain permit and requires flood-fringe residences to place the lowest floor at least two feet above base flood elevation33.
  5. Determine whether the septic design is covered by a general permit or needs a state construction permit, then leave the tank and laterals uncovered for Cass County's inspection96.
  6. Resolve county-road access with Planning & Zoning or obtain a state permit for a new, moved or altered state-highway driveway1234.
  7. Call at least 24 hours ahead for county inspections, complete the state electrical inspection first when required, and obtain the certificate of occupancy before moving in354.

What should you check before buying land in Cass County?

Start with jurisdiction and the official zoning map because municipal extraterritorial authority can displace county zoning87. Confirm the use, minimum lot area, height, setbacks and access before closing21222312. Ask whether a split or boundary change needs county platting or replatting review16. Check septic feasibility early because only about 5.9% of county soils are rated without severe limits for a conventional drain field27. Check the floodplain overlay because Cass County imposes elevation and documentation rules beyond the permit itself33. A new, moved or altered entrance on a state highway requires a state permit34. Cass County's effective property-tax rate is about 1.4%, with a median annual bill near $3,5453637. We could not confirm a countywide private-well permit rule, so ask Planning & Zoning and Nebraska DWEE before treating a parcel as water-independent1229.

Watch-outs

  • A Cass County building permit becomes void after six months without substantial progress, and required inspections need at least 24 hours' notice3835.
  • Only about 5.9% of Cass County soils are rated without severe limitations for a conventional septic drain field, making a professional site evaluation important before purchase27.
  • Permanent residence is prohibited in Cass County RV parks and campgrounds except for specified staff, but private-parcel RV occupancy, temporary camping and private-well permitting remain unconfirmed; ask Planning & Zoning and Nebraska DWEE111229.

    • Camping is unlawful except at places designated as campsites by the Department of Transportation, the county, or another governmental entity owning or controlling the property.
    • The statute excludes certain lands transferred or leased to the Game and Parks Commission and other lands controlled by the Game and Parks Commission or a natural resources district, which are governed under separate statutes.
    • Camping includes temporary lodging out of doors in a sleeping bag, tent, trailer, station wagon, pickup camper, camper-bus, or other vehicle.

  • Tiny homesLimited

    Tiny houses produced or sold in Nebraska and classified as manufactured homes, modular housing units, or recreational vehicles, including park model recreational vehicles.

    • The Nebraska Public Service Commission states that tiny houses can be built as either a manufactured home, modular housing unit, or recreational vehicle.
    • For a park model recreational vehicle under current Nebraska law, the unit must be designed and marketed as temporary living quarters for recreational, camping, travel, or seasonal use; must not be permanently affixed to real property for use as a permanent dwelling; must be built on a single chassis mounted on wheels; must have a gross trailer area not exceeding 400 square feet in the setup mode; and must be certified by the manufacturer as complying with ANSI A119.5, 2025 edition.
    • LB1147 enacted the 400-square-foot park-model limit and specified the 2020 ANSI A119.5 edition; its emergency clause states that the act takes effect when passed and approved according to law.
    • State classification or construction compliance does not establish unrestricted land-use occupancy. County zoning resolutions may regulate the location, size, and uses of structures including house trailers and automobile trailers, and may regulate uses of buildings and land in unincorporated areas.
    • County zoning powers do not apply within incorporated cities or villages, or areas where a city or village has been granted and is exercising zoning jurisdiction. Local zoning, building, utility, health, and other requirements may therefore impose additional conditions.

    park model gross trailer area: <= 400 square feet (Measured in the setup mode.) · park model chassis: single chassis mounted on wheels · park model permanent-affixation: false (The unit must not be permanently affixed to real property for use as a permanent dwelling.)
