Cedar County, Nebraska requires a building permit to erect, move, add to or structurally alter a building in the county zoning area1. Agricultural nonresidential structures in AG Agricultural Residential Districts and improvements valued at $1,000 or less are exempt from that permit requirement2. Cedar County also has district-based zoning, while Nebraska's state onsite wastewater program governs septic systems34.

Do you need a building permit in Cedar County, Nebraska?
Yes. Cedar County requires a building permit before a building or other structure is erected, moved, added to or structurally altered in the county zoning area12. A permit is not required for an agricultural nonresidential building or structure in an AG Agricultural Residential District, or for an improvement valued at $1,000 or less2. The exemption is narrow: it does not turn a residence, or every structure on agricultural land, into permit-free construction2. Nebraska also has a state building code that applies by default where a local jurisdiction has not timely adopted an authorized local code, except for construction on a farm or for farm purposes13. The specific building-code edition adopted or enforced by Cedar County could not be confirmed, so ask the Zoning Administrator before finalizing plans114.
Who issues building permits in Cedar County, and how do you reach them?
The Cedar County Zoning Administrator is the practical first call for a county building permit or zoning question: the office is at 101 S. Broadway in Hartington and can be reached at 402-254-687014. A building-permit application must include a plot plan with the site and structure information required by the zoning regulations15. The Zoning Administrator approves or disapproves an application within 30 days after receipt, and required fees must be received before an approved permit is issued15. Cedar County has not published a confirmed fee schedule in the materials available here, so ask the office for the current amount15. Once issued, construction must begin within 90 days, and the permit remains valid for 2 years12. A written appeal goes to the Board of Adjustment within 10 days after the determination is filed15.
Does Cedar County have zoning?
Yes. Cedar County divides its zoning area into districts with district-specific controls over land use, building size, height and intensity165. Nebraska county zoning authority generally covers territory outside incorporated cities and villages, except unincorporated areas where a city or village is exercising granted or ceded zoning jurisdiction17. In the A-1 district, a new single-family dwelling needs at least 80 acres as a permitted use or 40 acres as a conditional use, subject to the ordinance's exemptions and rules for nonconforming lots18. Confirm the parcel's district before relying on those figures because other districts have different standards18. A-1 rules also specify a 30-foot front yard, 15-foot side yard and 25-foot rear yard, plus separate road-centerline setbacks in specified locations19. Structures intended for human occupancy in A-1 are capped at 35 feet under the cited district rule20.
How do septic permits work in Cedar County?
Nebraska's Department of Water, Energy, and Environment administers onsite wastewater rules in Cedar County under Title 124, and any local requirements apply in addition to the state program421. Most Nebraska onsite wastewater systems are built under Authorization by Rule without a construction permit, but systems with large size, non-domestic wastes or siting issues can require a site-specific state permit6. A system that is constructed, reconstructed, altered, modified or otherwise changed must be registered with the state6. Septic work and inspection must be performed or supervised by an appropriately certified professional or another professional authorized by state law22. Call the state Onsite Section at (402) 471-4285 for program questions and certified-professional resources23. Only 31% of Cedar County soils lack severe limits for a conventional drain field, so make the site evaluation part of due diligence rather than assuming a standard field will work9.
Can you live in an RV or tiny home on land in Cedar County?
Cedar County's rules for long-term RV occupancy, temporary camping on private land and tiny-home occupancy could not be confirmed, so take the parcel address and proposed use to the Zoning Administrator before buying or moving a unit onto the land314. Nebraska's restriction on camping along public highways, roadside areas and public parks does not answer whether someone may occupy an RV on private property24. Cedar County does have a confirmed district-specific size rule: each mobile home in the R-M Mobile Home Residential District must contain at least 500 square feet of livable floor area8. That mobile-home rule is not a countywide tiny-home standard8. Nebraska law permits counties to impose certain standards on manufactured homes, but it does not itself impose a 900-square-foot minimum on every home statewide25.
Building a home in Cedar County: the steps, in order
- Ask the Cedar County Zoning Administrator to identify the parcel's zoning district and applicable use, lot-size, setback and height rules; call 402-254-6870145.
- Confirm that the lot was legally created and has legal access, because county subdivision rules govern platting and some exemptions also depend on access and suitable sanitation26.
- Arrange a septic site evaluation with a qualified professional and determine whether the system qualifies for Authorization by Rule or needs a state permit622.
- Submit the county building-permit application with the required plot plan and pay the applicable fee before issuance15.
- If access connects to a state highway, obtain the Nebraska driveway or approach-road permit before constructing, relocating or altering the entrance27.
- If the site is in a special flood hazard area, obtain the required floodplain approval before development28.
- Begin construction within 90 days and finish within the permit's 2-year validity period12.
What should you check before buying land in Cedar County?
Start with the zoning map, legal lot status and road access: Cedar County maintains zoning maps, regulates subdivision, and applies district-specific lot and setback standards52619. Check the FEMA flood designation before planning a house, driveway or grading, because development in Cedar County's identified special flood hazard areas requires full compliance with the floodplain resolution and other applicable rules28. Test septic feasibility early; only 31% of county soils lack severe limitations for a conventional drain field in the USDA soil survey9. The county receives about 28.8 inches of precipitation annually, and severe drought has occurred in about 21.4% of years, useful context for water planning but not a substitute for checking a specific well or water source2930. The effective property-tax rate is about 1%, with a median annual bill of $1,8271011.
Watch-outs
- A permit exemption for an agricultural nonresidential structure in an AG district does not establish an exemption for a house or residential farm building2.
- Cedar County's published permit process requires fees, but the current fee amounts could not be confirmed; ask the Zoning Administrator before budgeting1514.
- Floodplain development needs separate compliance even when the underlying use is otherwise allowed by the zoning district28.
