Building permits, zoning and septic rules in Lancaster County, Nebraska

Yes, in the area the county's permit rule covers: construction, alteration, repair, movement, removal, conversion, occupancy change or demolition within the City of Lincoln or within three miles of its corporate limits (outside another organized city or village) needs a building permit, with a separate permit for each building or structure¹. That rule does not by itself establish a permit requirement for every parcel in Lancaster County beyond that area¹, so ask Building and Safety about land outside the three-mile ring. Nebraska's statewide code uses the 2018 International Building, Residential and Existing Building Codes and the 2018 Uniform Plumbing Code, but local jurisdictions may adopt a generally conforming local code; the specific edition adopted for unincorporated Lancaster County could not be confirmed⁸. An owner may perform or arrange work on the owner's own property without contractor registration, but that narrow exemption does not remove applicable building permits, inspections or code requirements⁷. A new or changed land or building use governed by the county zoning resolution cannot be occupied until a certificate of occupancy confirms compliance with zoning, special-permit conditions and the Building Code⁹.

Lincoln/Lancaster County Building and Safety is the first stop for building, electrical, mechanical and plumbing permits in Lincoln and the surrounding county area it serves. The office is at 555 South 10th St, Suite 203 in Lincoln and its main number is 402-441-7521¹⁰. Required inspections can be scheduled at 402-441-5999¹⁰. The county zoning resolution specifically requires Building and Safety to inspect premises covered by a special permit before a certificate of compliance is issued, and a mobile home must be inspected before occupancy⁹. Building and Safety also handles floodplain information; any development in a Nebraska floodplain requires a separate permit, including grading, filling, additions and new structures^10,11. The county resolution adopting the 2021 International Existing Building Code says enforcement is provided through the City Codes Administration under an interlocal agreement¹². Permit fees were not confirmed, so ask Building and Safety for the current fee and submittal list for the proposed work.

Yes. Lancaster County zoning applies within the county's zoning jurisdiction, principally the unincorporated county, and regulates land and building uses, building height, yards and development intensity². The published resolution includes AG, AGR, R and other districts, each with rules for use, height, yards and development intensity². Incorporated municipalities may administer their own zoning, so verify which jurisdiction controls before relying on county rules². The Lincoln/Lancaster County Planning Department can identify a parcel's district; call 402-441-7491¹³. In the AG district, one accessory dwelling may be approved by special permit on a lot of at least 20 acres⁶. It is limited to the lesser of 1,000 square feet or 40% of the principal home, may have no more than 2 bedrooms, and must meet owner-occupancy, deed-restriction, access, utility and siting conditions⁶. An individual-lot mobile home in the applicable district must have at least 800 square feet excluding garages². That rule is not a confirmed minimum for every dwelling.

Nebraska's Onsite Wastewater Program administers septic design standards, professional certification, subdivision review, registration and site-specific permitting in Lancaster County³. Most systems are constructed under a General Permit and do not need a separate state Construction Permit; a system that does not meet the General Permit requirements must receive a Construction Permit before construction, with triggers including wastewater quantity, wastewater quality and site conditions⁴. Off-grid does not mean sanitation-free: any dwelling or other building generating wastewater must use a compliant onsite system, public sewer or other compliant wastewater works, and a system must be registered when it is built or changed³. Installation and inspection must be performed or supervised by an authorized certified professional, Nebraska-licensed engineer or registered environmental health specialist¹⁴. Only 0.3% of Lancaster County soils rate as free of severe limitations for a conventional drain field, so obtain a site evaluation before treating a standard gravity system as feasible¹⁵. The state program can be reached at (402) 471-4285¹⁶.

We could not confirm a county rule that generally allows RV living or tiny-home occupancy on private land in Lancaster County. A county-regulated campground requires a special permit in the AG district and must meet campsite, lot-size, access, water, sewage, setback and recordkeeping requirements⁵. That campground rule does not establish permission to occupy an RV as a residence on an ordinary private parcel. Ask the Lincoln/Lancaster County Planning Department whether the parcel's district permits the proposed use, and ask Building and Safety what construction and occupancy approvals apply^10,13. Nebraska may classify a tiny house as a manufactured home, modular unit or recreational vehicle, but that state classification does not override local zoning, building, utility or health requirements¹⁷. The county's accessory-dwelling option is narrower: one accessory dwelling may be considered by special permit in the AG district on a qualifying lot⁶. The confirmed 800-square-foot threshold applies to an individual-lot mobile home in the applicable district, not every tiny or site-built home².

1. Ask the Lincoln/Lancaster County Planning Department to confirm the parcel's jurisdiction, zoning district and allowed use^2,13.
2. If the proposal needs a county special permit, file the application and plot plan with Planning; the County Board refers it to the Planning Commission, which holds a public hearing, and its action may be appealed to the County Board⁵.
3. Establish wastewater service through a compliant onsite system, public sewer connection or other compliant wastewater works; contact the state program about registration, General Permit eligibility and any required Construction Permit^3,4.
4. Apply to Lincoln/Lancaster County Building and Safety for the required building and trade permits, and confirm first whether the parcel falls within the permit area^1,10.
5. Get a county driveway permit for any access to a Lancaster County road, and obtain any separate floodplain permit or state-highway driveway permit that the site requires^11,18,19.
6. Complete required inspections, then obtain the certificate of occupancy when the project creates or changes a use or occupancy classification governed by county zoning⁹.

Start with jurisdiction and zoning because a municipality may control a parcel that appears rural, while county zoning governs principally unincorporated territory². Budget for a site-specific wastewater evaluation: only 0.3% of county soils rate as free of severe limitations for a conventional drain field¹⁵. Check flood maps before planning grading, access or structures because all Nebraska floodplain development requires a permit¹¹. A driveway permit is required for any access to a Lancaster County road; the applicant provides the property's legal description and marks the driveway location with two wire flags, county engineering staff check sight distance and drainage, there is no charge, and review takes about 10 working days¹⁸. A new, relocated or altered connection to a state highway requires a state permit instead¹⁹. Private-well permitting also could not be confirmed, so identify the water source and ask Planning which authority must approve it¹³. The median property-tax bill is about $4,055 a year and the effective rate is about 1.6%, but verify the actual parcel assessment before closing¹⁵.
