Unincorporated Adams County, Nebraska requires a separate zoning/building permit for each building, issued by Adams County Planning & Zoning, which also administers county zoning12. A certificate of occupancy is required before a structure or land is used3. Hastings, the named villages and their extraterritorial areas fall outside county zoning2. Septic permits are state-run: the Nebraska Department of Water, Energy, and Environment, not the county, administers them4.

Do you need a building permit in Adams County, Nebraska?
Yes. Unincorporated Adams County requires a separate zoning/building permit application for each building, supported by a site drawing showing existing and proposed buildings, dimensions and setbacks1. County-regulated construction in unincorporated Adams County is subject to an adopted building code, but the regulations do not identify its title or edition or enumerate the applicable electrical, mechanical and plumbing codes1314. County zoning officials may enter the property during normal working hours for zoning-compliance inspection, although a comprehensive structural inspection schedule was not confirmed15. Ask Adams County Planning & Zoning which code edition and reviews apply before finalizing plans16. These county rules apply to unincorporated Adams County; inside the Village of Kenesaw, building permits come from the village's Building Inspector17. An owner may perform or arrange work on the owner's own property without becoming a contractor under the state Contractor Registration Act, but that exemption does not remove the county permit requirement101.
Who issues building permits and zoning approval in Adams County?
Adams County Planning & Zoning is the first stop for the county zoning/building permit, zoning maps and regulations16. Call 402-461-7174 or visit 500 N Denver Avenue in Hastings, Nebraska16. The written application must use the Zoning Administrator's form and include scaled plans showing lot dimensions, building locations and uses, plus water and sanitary-sewer facilities as needed; stake the lot and building location before construction18. The Zoning Administrator issues a written permit or denial within 20 days after accepting the application18. The zoning regulations say permits expire if work does not start within 90 days or finish within one year unless extended in writing18. The county's permit form states longer periods, six months to begin and two years to finish, so ask Planning & Zoning which applies19. Inside the Village of Kenesaw, the village issues its own building permits through its Building Inspector and applies Adams County's zoning regulations within its limits and one-mile jurisdictional area1720. Septic permits do not come from this office; they run through the state's Onsite Wastewater Program6. The current county fee amount was not confirmed, so request the fee schedule directly from Planning & Zoning16.
Does Adams County have zoning?
Yes. Adams County zoning covers its unincorporated area except the named villages and their extraterritorial jurisdictions, plus Hastings and its mapped two-mile jurisdiction2. Zoning varies across the county depending on which jurisdiction a parcel falls in21. Inside Hastings, the city administers its own zoning; private onsite wastewater systems remain under the Nebraska Department of Water, Energy, and Environment Onsite Wastewater Program222324. The Village of Kenesaw has adopted the Adams County zoning regulations for its own territory20. The county regulations publish 19 districts, with airport-hazard and flood-hazard overlays that can add stricter rules25. Minimum lot area, setbacks, maximum lot coverage and maximum building height vary by district and use26272829. A single-story, single-family dwelling must contain at least 900 square feet above grade and have an exterior width of at least 18 feet, and the roof must be pitched with a rise of at least 2.5 inches per 12 inches of run930. Ask Planning & Zoning to identify the controlling jurisdiction, district and overlays before designing a home16.
How do septic permits work in Adams County, Nebraska?
The Nebraska Department of Water, Energy, and Environment administers Title 124 onsite-wastewater requirements in Adams County4. Most systems use a general permit, while a system outside those requirements needs a state construction permit before work begins; wastewater quantity, wastewater quality and site conditions can trigger that permit31. A construction permit is valid for two years from issuance, with a possible extension of no more than one year7. New or changed systems must be registered when Title 124 requires it424. A septic-tank owner must arrange periodic inspection by a Master or Journeyman Pumper, professional engineer or registered environmental health specialist and have septage removed at the state rule's sludge or scum thresholds32. Reach the Onsite Wastewater Program at (402) 471-4285 or DWEE.onsite@nebraska.gov24. Only 24% of Adams County soils are rated without severe limitations for a conventional drain field, so arrange a site evaluation before choosing the house location33.
Can you live in an RV or tiny home on land in Adams County?
We could not confirm an Adams County rule that generally allows or prohibits long-term RV occupancy on private land, temporary private-land camping or tiny-home occupancy34. Within Adams County’s unincorporated zoning jurisdiction, an RV in a mapped special flood-hazard area must stay fewer than 180 consecutive days, be fully licensed and ready for highway use, or meet manufactured-home permit, elevation and anchoring requirements835. Highway readiness requires wheels or a jacking system, only quick-disconnect utilities and security devices attaching the RV to the site, and no permanently attached additions8. Ask Adams County Planning & Zoning about the proposed unit and occupancy before placement16. Adams County requires a certificate of occupancy before a structure or land is used or its use changes, prohibits using a structure as a temporary residence, and will not issue a residential certificate for a partially completed building or portion36. A single-story, single-family dwelling must have at least 900 square feet above grade and an exterior width of at least 18 feet9.
What are the steps to build a home in Adams County?
- Ask Adams County Planning & Zoning to confirm jurisdiction, zoning district, overlays, proposed use and dimensional standards23716.
- Have a certified onsite professional evaluate wastewater needs and determine whether the system qualifies for general-permit coverage or needs a construction permit31.
- If drilling a well in a groundwater management area, ask the applicable natural resources district whether a permit is required; exemptions and district rules can change the answer38.
- Submit the prescribed county application with scaled plans, then stake the lot and building location before construction18.
What should you check before buying land in Adams County?
Verify the controlling jurisdiction, zoning district, allowed use, lot size, setbacks, lot coverage and height standards with Adams County Planning & Zoning before closing413727282916. Confirm that any proposed land division can be approved and recorded before relying on it for a sale, permit or construction42. Check flood maps because development in mapped hazard areas requires a floodplain development permit, and flood-prone lots face added platting and elevation restrictions4344. Test septic feasibility early because only 24% of county soils are rated without severe limitations for a conventional drain field33. In unincorporated Adams County’s zoning jurisdiction, a zoning permit is required before construction or connection to water or sewer facilities; that rule does not establish a universal public-utility hookup requirement45. Only the C-1 Village Development District states that uses and structures needing water and sanitary sewer should connect to municipal or community systems, so ask Planning & Zoning whether the parcel's district sets a connection standard before relying on a well and septic system4616. For budgeting, the effective property-tax rate is about 1.4%, and the median annual property-tax bill is $2,6704748.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
