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

Unincorporated Douglas County, Nebraska requires a building permit for new construction, issued by Douglas County Environmental Services' Permits and Inspections Division¹. State law requires that county building permit for nonfarm buildings in the zoned unincorporated area, and a farm exception applies to agricultural buildings on a farmstead of 20 acres or more producing at least $1,000 of farm products a year¹. The division generally covers only unincorporated western Douglas County, plus contract permit and inspection work for Bennington, Valley and Waterloo; Omaha and other cities issue their own building permits, while septic permits stay with the Douglas County Health Department in every city and in the unincorporated area^3,4. Nebraska's Contractor Registration Act exempts a person working on their own property from contractor registration, but the exemption does not remove applicable permits, inspections or codes⁸. Nebraska's state building code uses the 2018 International Building Code, International Residential Code and Uniform Plumbing Code, with exceptions, where a local government has not timely adopted an authorized local code; farm construction is excluded from that default rule¹⁰. A State Fire Marshal certificate of occupancy is also required before use or occupancy only for facilities subject to State Fire Marshal inspection and the applicable state chapter¹¹.

Douglas County Environmental Services' Permits and Inspections Division issues building permits and performs inspections for unincorporated western Douglas County³. Reach the division at 402-444-7189, at 15335 West Maple Road, Suite 201, Omaha, NE 68116³. The division will not issue a permit for new home construction until you show the site is served by public water and sewer, or until the Douglas County Health Department has approved a private septic system and well — so line up your septic or utility approval before you expect a building permit^3,4. Stormwater and erosion-control measures must also be in place before the division will issue a residential or commercial building permit; its Stormwater & Floodplain contact is 402-444-4590³. Apply, pay fees and track inspections through the county's SmartGov online permitting portal³.

Douglas County has county zoning in its unincorporated area, administered by Environmental Services' Land Use and Zoning group; reach its Planning and Zoning Coordinator line at 402-444-7924^2,3. Omaha and the other incorporated cities set their own zoning for land inside their limits and, in some cases, just outside them⁶. Nebraska law lets a county board adopt a zoning resolution regulating buildings, lot coverage, setbacks, density and land use in the unincorporated county, but that power stops at city and village limits and inside any area where a city or village has been granted or is exercising its own zoning jurisdiction¹². Because Douglas County contains Omaha, a primary-class city, the county also has subdivision-platting authority outside areas a city or village is already regulating — except the county has no power to require plat approval when the smallest parcel created is more than 10 acres¹³. If a manufactured home is part of your plan, the county board may require it to carry a HUD or manufactured-housing seal and may impose the same foundation, setback and minimum-square-footage standards it applies to a site-built home, including a floor area of at least 900 square feet, though Nebraska does not impose that minimum on every home statewide¹². Nebraska also exempts agricultural buildings on a farmstead of 20 acres or more producing at least $1,000 of farm products a year from being treated as ordinary nonfarm buildings, though the county board still decides whether a residence on that same farmstead is covered by county zoning¹⁴.

Douglas County Health Department's Environmental Health Section locally permits and inspects septic systems, while the Nebraska Onsite Wastewater Program administers the statewide design and professional-certification rules^4,5. Reach the county section at 402-444-7485, at 1111 South 41st Street, Ste. 205, Omaha, NE 68105⁴. For a new or expanded home, obtain the county's septic and well approval, or document public water and sewer service, before seeking the county building permit^3,4. A state permit is required for systems handling 1,000 gallons per day or more, managing non-household wastewater, or not covered by Authorization by Rule, with a $450 application fee covering both construction and operating permits⁷. Most Nebraska onsite systems qualify for Authorization by Rule and need no separate state construction permit; wastewater quantity or quality, or site conditions outside that authorization, can trigger state permitting and site-specific review^5,7. Every constructed or altered onsite system must also be registered with the state¹⁵. A development area that proposes onsite systems on lots under 3 acres needs state subdivision approval first⁵. Any dwelling or other building that generates wastewater must use a state-compliant onsite treatment system or connect to public sewer or other wastewater works⁵. Only about 27.6% of county land lacks severe soil limitations for a conventional drain field, so evaluate the actual homesite early⁹.

We could not confirm a Douglas County rule allowing residential use of an RV or tiny home on private land in the unincorporated county³. Nebraska's public-property camping rule does not answer whether you may occupy an RV on your own parcel¹⁶. Douglas County zoning still controls the parcel's allowed uses, while Nebraska law permits counties to apply foundation, utility-connection, setback and floor-area standards to manufactured homes^2,12. Off-grid sanitation is possible only in the limited sense that a dwelling may use an onsite wastewater system instead of public sewer when that system complies with Nebraska regulations; this does not itself authorize the dwelling or RV use⁵. Call Land Use and Zoning at 402-444-7924 with the parcel number and proposed structure before buying³.

1. Confirm the parcel is in unincorporated western Douglas County rather than Omaha or another city, because the issuing department changes by jurisdiction³.
2. Call Douglas County Land Use and Zoning at 402-444-7924 to confirm the zoning district, allowed use, subdivision issues and setbacks³.
3. Contact the Douglas County Health Department at 402-444-7485 for local septic and private-well approval, and ask whether site conditions or the proposed system also require a state permit^4,7.
4. Put stormwater and erosion controls in place and address any floodplain permit; the Stormwater & Floodplain line is 402-444-4590³.
5. Apply through SmartGov after documenting septic and well approval or public water and sewer service³.
6. Schedule construction inspections with Permits and Inspections at 402-444-7189, and ask whether the completed facility falls under the State Fire Marshal certificate-of-occupancy rule^3,11.

Douglas County is Omaha's home county, about 6 miles from the metro area with a population density around 1,806 people per square mile, so a genuinely rural parcel here means the unincorporated western edge of the county, not the county as a whole⁹. Typical farmland runs about $9,113 an acre and a typical home is valued near $300,227⁹. The county gets about 32.7 inches of precipitation a year and has been in severe drought in roughly 16.5% of recent years, worth planning for if you'll rely on a private well⁹. If your driveway connects to a state highway, Nebraska requires its own driveway or approach-road permit through the Department of Transportation before you can build the entrance, separate from any county or city process¹⁷. Any development in a floodplain, including an addition or a new structure, needs a floodplain development permit and must meet Base Flood Elevation requirements¹⁸. Budget for an effective property tax rate near 1.7%, a median bill around $4,295 a year, and a typical home insurance premium near $2,659 a year⁹.
