Do you need a building permit in Sarpy County, Nebraska?
Yes. Sarpy County requires a permit before erecting, constructing, altering or converting a nonfarm building or structure in its zoned jurisdiction1. County zoning applies outside city corporate limits and city or village zoning jurisdictions2. The county-administered area uses amended building codes adopted in 2024, including the 2018 international building, residential, plumbing, mechanical, energy-conservation and fuel-gas codes and the 2023 National Electrical Code as temporarily amended3. A county permit is valid for one year, and construction must begin within the first six months4. A grading permit is required when more than 1 acre will be disturbed, while any work or grading in a mapped floodplain needs a floodplain development permit4.
Who is the Sarpy County building department, and how do you reach them?
The Sarpy County Building Department, within Planning & Building, handles county building permits; its verified contact is listed above4. Permit applications must use the Building Department's form, be complete, identify the property's legal description and owner and applicant, describe the proposed uses, and provide other information needed to enforce the zoning rules12. The Planning Division evaluates zoning changes, special-use permits and floodplain permits and reviews site and subdivision plans11. Public Works separately handles permits to occupy or use county road right-of-way; applications go by email, same-day requests are not accepted, and applicants should allow about two business days for a reply13. The available county material does not establish every inspection stage, so ask the Building Department for the inspection schedule when filing.
Does Sarpy County have zoning?
Yes. Sarpy County zoning applies outside the corporate limits and zoning jurisdiction of any city or village2. Published county districts include agricultural, residential-estate, conventional residential, manufactured-home residential, business, industrial, mixed-use, airport, planned-development, floodplain and other districts14. The county's own district summary identifies AG as 20 or more acres, AGD as 10 or more acres, AGR as 5 or more acres, RE1 as 1 or more acres and RE2 as 2 or more acres15. Those district labels do not by themselves answer a parcel's setbacks, building height, lot coverage, minimum dwelling size or permitted use. Ask the Planning Division to identify the parcel's district and applicable dimensional table before designing a home or splitting land11. County Board approval is required before unincorporated real property is subdivided, platted or laid out into building lots or streets, subject to the statute's jurisdictional exceptions10.
How do septic permits work in Sarpy County?
Nebraska's onsite wastewater program regulates septic systems, while most standard systems proceed under Authorization by Rule and must be registered with the state16. A site-specific state permit applies when a system's large size, non-domestic waste or siting issue requires individual evaluation7. Any dwelling or non-dwelling that generates wastewater must use an onsite treatment system compliant with state rules or connect to public sewer or another wastewater works; going off-grid does not remove that sanitation requirement59. Only about 11% of Sarpy County soils avoid severe limits for a conventional drain field, so evaluate soils before fixing a house location or purchase budget6. The county fee schedule includes a septic-permit charge based on plumbing fixtures, but the available material does not establish a general county septic-inspection requirement17. Ask Planning & Building what local submission and fee apply to the parcel, and use a qualified onsite professional for the state process11.
Can you live in an RV or tiny home on your land in Sarpy County?
We could not confirm a blanket Sarpy County rule allowing long-term RV occupancy, temporary private-land camping or tiny-home occupancy. County zoning still applies in the unincorporated county outside city and village zoning jurisdictions, so Planning must confirm whether the proposed dwelling type and occupancy are allowed in the parcel's district211. The published zoning list includes a manufactured-home residential district, but that listing alone does not establish where a manufactured home is allowed or what occupancy conditions apply14. A tiny or mobile dwelling that generates wastewater still must connect to public sewer or other wastewater works or use an onsite system that complies with state regulations59. An owner working on the owner's own property is exempt from contractor registration, but that exemption does not waive building permits, zoning, inspections or sanitation rules8.
Building a home in Sarpy County: the steps, in order
- Confirm that county zoning and permitting, rather than a city or village jurisdiction, governs the parcel2.
- Ask the Planning Division for the district, permitted use and parcel-specific dimensional standards; obtain County Board approval before subdividing unincorporated land1110.
- Plan wastewater service: connect to an approved sewer or design a compliant onsite system, including a site-specific state permit when size, waste type or siting requires one57.
- Obtain grading or floodplain approval when the county's stated triggers apply, and coordinate county right-of-way work with Public Works413.
- File the county's prescribed building-permit form with the legal description, owner and applicant, proposed uses and required supporting information12.
- Confirm the project fee from the county schedule because charges vary by project type, value, size, category, timing and fixture count17.
- Start work within six months; the county permit is valid for one year4.
What to check before you buy land in Sarpy County
Confirm the governing jurisdiction and zoning district before assuming a parcel is buildable or divisible210. Ask Planning for the current setbacks, minimum dwelling size, lot coverage and height limits because the available district list does not answer those parcel-specific questions1411. Pull the floodplain map because any work or grading in a mapped floodplain needs county approval4. Investigate wastewater service and soils early: only about 11% of the county's soils avoid severe limits for a conventional drain field, while every wastewater-generating dwelling must use compliant onsite treatment or an approved sewer connection65. Verify legal access with Public Works if county right-of-way is involved13. Budget for permit fees that vary by project and for property taxes near a 1.8% effective rate, with a median annual bill of about $5,157171819.
Watch-outs
- An owner-builder exemption only removes contractor-registration status; Sarpy County permits, zoning, inspections and sanitation rules still apply8.
- Sarpy County's fee schedule lists permit, inspection, occupancy, well and septic charges, but a listed fee does not by itself prove which permit or inspection a particular parcel needs17.
- We could not confirm private-land RV, tiny-home, minimum-size or setback rules; ask the Planning Division about the parcel's zoning district before buying or placing a dwelling11.
- Sarpy County Public Works does not accept same-day right-of-way permit requests and asks applicants to allow about two business days for a reply13.
