Do you need a building permit in Custer County, Nebraska?
Yes, in the practical sense that rural construction must start with county zoning approval: Custer County says no building or structure may be erected, moved, enlarged or structurally altered until the Zoning Administrator issues a zoning permit12. Houses, additions and several agricultural or commercial uses are among the projects the county directs through that office2. The available county materials do not confirm a separate residential construction-code permit or an ordinary building-inspection program, so ask Planning and Zoning what reviews apply to the exact project2. Nebraska also has a state building code whose application depends on local adoption and statutory defaults, with a farm-purpose exception to that default rule9. A parcel in a floodplain needs the Floodplain Administrator's approval before the county zoning permit can issue4.
Who handles Custer County building and zoning permits?
Custer County Planning and Zoning is the first stop for a project in the county's jurisdiction because the office evaluates zoning and conditional-use permits, reviews subdivisions and administers the zoning regulations2. Call (308) 872-2410, email [email protected], or visit 431 S 10th in Broken Bow, Nebraska2. The county says permit forms may be picked up at the Zoning Office in the Custer County Courthouse2. No separate Custer County building department or general residential inspection contact could be confirmed, so use Planning and Zoning to identify every county approval that applies before work begins2. County zoning-permit fees also could not be confirmed from the reviewed facts; ask the office for the current fee resolution and the correct application for the proposed structure2.
Does Custer County have zoning?
Yes. Custer County has adopted zoning and subdivision regulations administered through its Zoning Administrator and Planning Commission3. Nebraska county zoning authority covers territory outside incorporated cities and villages, except where a city or village is exercising granted or ceded zoning jurisdiction10. That boundary matters: a Broken Bow address does not by itself establish which government controls the parcel. Ask County Planning and Zoning to identify the zoning district, allowed residential use, setbacks and any conditional-use review for the parcel2. A general county minimum dwelling size, residential lot-coverage limit and tiny-home standard could not be confirmed. Nebraska law allows a county board to apply certain standards to manufactured homes, including a discretionary minimum of 900 square feet, but that state authority does not prove Custer County adopted that minimum11.
How do septic permits work in Custer County?
Nebraska's Onsite Wastewater Program administers septic requirements in Custer County, while any local requirements would apply in addition to the statewide rules512. Most Nebraska onsite systems are constructed under a General Permit without a separate state construction permit, but systems with qualifying size, wastewater-quality or site-condition issues need a construction permit before work and an operating permit before use when applicable6. The state application fee for that combined construction-and-operating permit process is $4506. New or changed systems must be registered, and onsite work must be performed by a properly certified professional1314. Call the Nebraska Onsite Wastewater Program at (402) 471-4285 or email [email protected]15. Only about 21.8% of Custer County soils are rated without severe limitations for a conventional drain field, so make a site evaluation part of the purchase contingency8.
Can you live in an RV or tiny home in Custer County?
A general rule for occupying an RV on private land in unincorporated Custer County could not be confirmed, and Nebraska's rule for camping on public highways, roadside areas and parks does not answer private-land occupancy16. Ask Custer County Planning and Zoning whether an RV may be occupied on the parcel, for how long, and whether construction of a primary home changes the answer2. A specific countywide tiny-home occupancy rule and general minimum dwelling size also could not be confirmed. A tiny home treated as a structure still enters the county zoning-permit process before it is placed, erected or altered12. Any occupied dwelling that generates wastewater must connect to public sewer or use an onsite wastewater system that complies with Nebraska requirements17.
Building a home in Custer County: the steps, in order
- Ask Custer County Planning and Zoning to confirm jurisdiction, the parcel's district, allowed use, setbacks and the required zoning application32.
- Confirm legal access with the road authority; a new, moved or altered driveway connecting to a state-highway right of way requires a Nebraska permit18.
- Have the county determine whether the site is in a regulated floodplain, because floodplain approval must precede the zoning permit there4.
- Submit the county zoning-permit materials before erecting, moving, enlarging or structurally altering the house12.
- Use a state-certified onsite professional to evaluate, install and register the wastewater system, and determine whether the General Permit or a site-specific state permit applies619.
- An owner working on the owner's property is exempt from contractor registration, but that exemption does not waive zoning, wastewater or floodplain approvals7.
What should you check before buying land in Custer County?
Confirm the zoning district and jurisdiction with Custer County Planning and Zoning before relying on a listing's description of allowed use32. Check the proposed building site against floodplain mapping because development in a regulated floodplain needs county approval before the zoning permit4. Order a parcel-specific septic evaluation because only about 21.8% of county soils are rated without severe limitations for a conventional drain field8. Verify the water source, well feasibility and legal road access; a state-highway driveway requires state approval, while a general county-road driveway rule could not be confirmed182. Custer County averages about 24.3 inches of precipitation annually, and severe drought has occurred in about 19.3% of years, so water planning deserves early attention2021. The effective property-tax rate is about 1.2%, with a median annual bill of about $1,8492223.
Watch-outs
- Custer County calls its construction approval a zoning permit; the available materials do not confirm a separate residential building-code permit or routine inspection program12.
- Floodplain approval comes before the zoning permit when the proposed site is in a regulated floodplain4.
- Most septic systems use a General Permit, but difficult sites and qualifying systems can require state construction and operating permits6.
- RV occupancy, tiny-home occupancy, county-road driveway approval and current county zoning fees remain unconfirmed; ask Custer County Planning and Zoning before committing to a parcel or project2.
