Building permits, zoning and land rules in Richardson County, Nebraska

Unincorporated Richardson County lists no county building permits; the Planning and Zoning permits page reads "None at this time, to be determined"¹. That does not make a project code-free. Nebraska's state building code applies by default where a county did not adopt its own authorized code within two years of a state-code update, and we could not confirm which path Richardson County took². The default rule excepts construction on a farm or for farm purposes². The state code rests on the 2018 International Residential Code and 2018 International Building Code, with listed exceptions¹².

State electrical inspection is the requirement most likely to reach a new home: a new single-family installation that needs new electrical service equipment is subject to inspection³. The request goes in at or before the start of work, with a $0.50 supervisory fee, and a late request carries a $250 delinquent fee³. An owner may do electrical work on a principal residence no larger than a single-family dwelling, or on farm property, without a license, but the exemption does not remove the permit and inspection requirements^9,13.

Richardson County lists no county construction-permit program, so call Planning and Zoning at 402-245-2911 to confirm what applies to your parcel and whether new regulations have taken effect^1,5. The county's rules apply to unincorporated land. Inside Humboldt, the city issues its own building permits through a written application to the City Clerk, and sets its own zoning^6,7. Septic permits for every address in the county, city or not, come from the state Onsite Wastewater Program^14,15.

County-road access permits come from Roads and Bridges, which handles the county's public roads, bridges and culverts¹⁶. Access to a state highway follows a separate state permit process¹⁷.

Richardson County's proposed zoning regulations were never adopted, and the Planning Commission is working on a new comprehensive plan and possible zoning regulations^1,5. Unincorporated Richardson County is therefore not zoned today as far as we could confirm, but the county pages do not expressly say so, and setbacks, minimum lot size and minimum home size are unconfirmed; ask Planning and Zoning before you buy. Zoning in Humboldt is the city's own⁷. Nebraska counties may regulate buildings, setbacks, lot coverage and land uses outside incorporated places once they adopt zoning¹⁸. Subdividing is not unregulated: county-board approval is required before platting building lots or streets in unincorporated areas¹⁹.

Nebraska's statewide Onsite Wastewater Program regulates septic systems in Richardson County¹⁴. Construction, alteration, repair and operation need a state permit or qualifying general-permit coverage unless a Title 124 exemption applies⁴. Off-grid sanitation still needs a compliant system, and only domestic wastewater may enter it unless an operating permit approves otherwise⁴. Septic tanks must be inspected periodically by a qualified pumper, engineer or environmental health specialist and pumped when sludge or scum thresholds are reached⁴. About 13% of county soils rate as not limited for a conventional drain field, so plan on a site evaluation and possibly an engineered system²⁰. Contact the state program for permit guidance¹⁵.

We could not confirm a Richardson County rule on long-term RV living, private-land camping or tiny-home occupancy; ask Planning and Zoning about the parcel⁵. Nebraska classifies tiny houses as manufactured homes, modular units or recreational vehicles, and a park-model RV is temporary living space that cannot be permanently affixed as a dwelling²¹. The only county-area RV rule we found covers RV parks inside Falls City's zoning jurisdiction, which limits each RV to four continuous months in any 12-month period; it does not govern an RV on your own land²². A dwelling that generates wastewater must connect to public sewer or use a compliant onsite system¹⁴.

1. Confirm whether the parcel is unincorporated or inside a city such as Humboldt, then ask Planning and Zoning about current county rules^5,6.
2. If creating lots or streets, get county-board approval for the subdivision or plat¹⁹.
3. Confirm which building code applies and plan for state electrical inspection if the home needs new service equipment^2,3.
4. Evaluate soils, then ask the state Onsite Wastewater Program whether the design needs an individual permit, general-permit coverage or an exemption^4,15,20.
5. Check well requirements with the Nemaha Natural Resources District; its cited rule covers high-capacity wells¹¹.
6. Apply to Roads and Bridges before installing or modifying a county-road access, or follow the state process for a state highway^10,17.
7. Ask whether the parcel lies in a mapped floodplain; state law requires a permit for floodplain development²³.

A county-road access needs a permit approved by the Highway Superintendent; fees start at $100 for small access and $150 for large access, with the final fee set by the Superintendent and paid in full before installation¹⁰. If a culvert is required it must be at least 18 inches in diameter and at least 30 feet long for residential access or 48 feet for agricultural access, and the owner maintains it¹⁰. Mail or email the completed form to the county Department of Roads¹⁰.

Floodplain development needs a permit under state law, but we could not confirm a county-specific floodplain ordinance, so ask Planning and Zoning^5,23,24. Get a soil evaluation before assuming a conventional septic field will work²⁰. Richardson County's effective property-tax rate is about 1.4%, and the median annual bill is about $1,329²⁰.
