Unincorporated Lancaster County, Nebraska requires building permits through Lincoln/Lancaster County Building and Safety1. County zoning governs land use, building height, yards and development intensity in the county's zoning jurisdiction2. Nebraska administers onsite wastewater systems; most use the state's General Permit, while systems that do not qualify need a Construction Permit before work begins34.

Do you need a building permit in Lancaster County, Nebraska?
Yes. Unincorporated Lancaster County requires building permits, and the joint Lincoln/Lancaster County Building and Safety operation issues them1. 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 confirmed9. 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 requirements8. 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 Code5.
Who issues Lancaster County building permits, and how do you reach them?
Lincoln/Lancaster County Building and Safety is the first stop for building, electrical, mechanical and plumbing permits in unincorporated Lancaster County. 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 occupancy11. Building and Safety also handles floodplain information; any development in a Nebraska floodplain requires a separate permit, including grading, filling, additions and new structures1012. Permit fees were not confirmed, so ask Building and Safety for the current fee and submittal list for the proposed work.
Does Lancaster County have zoning?
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. Incorporated municipalities may administer their own zoning, so verify which jurisdiction controls before relying on county rules2. The Lincoln/Lancaster County Planning Department maintains the city and county zoning and subdivision codes and can identify the rules for a parcel; 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, setback, height and separation conditions6. An individual-lot mobile home in the applicable district must have at least 800 square feet of floor area excluding garages7. That mobile-home rule is not a confirmed minimum size for every dwelling.
How do septic permits work in Lancaster County?
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. Installation and inspection must be performed or supervised by an authorized certified professional, Nebraska-licensed engineer or registered environmental health specialist14. Any dwelling or other building generating wastewater must use a compliant onsite system, connect to public sewer, or use other compliant wastewater works15. 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 feasible16. The state program can be reached at (402) 471-428517.
Can you live in an RV or tiny home on your land in Lancaster County?
We could not confirm a county rule that generally allows RV living or tiny-home occupancy on private land in Lancaster County. Nebraska's camping restriction addresses designated campsites on public highways, roadside areas, parks and similar public property, so it does not answer whether an RV residence is lawful on a private parcel18. 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 apply1310. A tiny home should not be confused with the county's specific accessory-dwelling option: in the AG district, one accessory dwelling may be considered by special permit only on a qualifying lot and must satisfy size, bedroom, owner-occupancy, deed, access, utility and siting conditions6. The county's confirmed 800-square-foot threshold applies to an individual-lot mobile home in the applicable zoning district, not automatically to every tiny or site-built home7.
Building a home in Lancaster County, Nebraska: the steps, in order
- Ask the Lincoln/Lancaster County Planning Department to confirm the parcel's jurisdiction, zoning district and allowed use132.
- 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 Board19.
- Establish wastewater service through a compliant onsite system, public sewer connection or other compliant wastewater works; contact the state program about General Permit eligibility, registration and any required Construction Permit154.
- Apply to Lincoln/Lancaster County Building and Safety for the required building and trade permits110.
- Obtain any separate floodplain permit or state-highway driveway permit that the site requires1220.
- Complete required inspections, then obtain the certificate of occupancy when the project creates or changes a use or occupancy classification governed by county zoning115.
What should you check before buying land in Lancaster County?
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 field16. Check flood maps before planning grading, access or structures because all Nebraska floodplain development requires a permit12. Lancaster County's complete driveway-permit requirement could not be confirmed; ask the road authority that maintains the frontage, and remember that a new, relocated or altered connection to a state highway requires a state permit20. 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 closing2122.
Watch-outs
- A county special permit follows a public process through Planning and the Planning Commission; do not assume a building-permit application alone approves a special use19.
- A certificate of occupancy is required before a new or changed use or occupancy classification governed by the Lancaster County zoning resolution may be occupied5.
- The confirmed 800-square-foot minimum applies to an individual-lot mobile home in the applicable district, not to every dwelling in Lancaster County7.
