Do you need a building permit in Bingham County, Idaho?

Yes. Unincorporated Bingham County requires a permit for any occupied structure, regardless of size, as well as additions, decks or porches, structural repairs or remodels, changes of use, manufactured-home placement, and other listed work1. An accessory structure needs a permit when it exceeds 200 square feet, or 120 square feet for a commercial accessory structure1. Bingham County has adopted the 2018 family of building, residential, energy, mechanical, fuel-gas, and existing-building codes with county and state amendments10. Electric service may not be used in a structure until the required building, zoning, or waiver permit has been secured11. Idaho separately requires permits for regulated electrical, plumbing, and HVAC work12.

Inside Blackfoot, the city handles building permits13. Inside Aberdeen, the city handles building permits under its own requirements and exemptions14. Southeastern Idaho Public Health remains the septic permitting authority for Bingham County5.

Who issues Bingham County building permits, and how do you apply?

Bingham County Planning and Development handles building and construction, code enforcement, land development, and planning and zoning15. Reach the department at 208-782-3177 or visit 490 N Maple, Suite A, Blackfoot, ID 8322115. Select the pertinent application, create a portal account, attach the required documents, and submit for staff review; after approval, pay for and print the permit, then request inspections through the same portal16. Commercial plans need Fire Marshal approval before they are submitted to the county17. After the final inspection passes, Bingham County issues a Certificate of Occupancy or Certificate of Completion when one applies to the project18. Bingham County’s current building and zoning fees took effect March 6, 2026; accessory structures require a non-refundable $100 deposit credited to an approved permit, and commercial plan review adds a non-refundable 25% of the permit fee19.

Does Bingham County have zoning?

Yes. Bingham County zoning applies across unincorporated land, except portions of tribal land inside the Fort Hall Indian Reservation where the county lacks jurisdiction20. Uses and dimensional standards vary by zoning district, and some uses require conditional-use approval2122. Blackfoot sets its own zoning inside city limits23. Aberdeen also has its own city zoning, while Southeastern Idaho Public Health handles septic permits there2425. For residences, the general side setback is 5 feet and the rear setback is 20 feet, while road and waterway setbacks vary with the feature26. Outside a platted subdivision, an approved residential parcel using division rights must contain at least 1 acre; subdivision minimums vary by zone and water and sewer service27. We could not confirm a countywide minimum dwelling size, lot-coverage limit, or general building-height limit; ask Planning and Development about those parcel-specific standards28.

How do septic permits work in Bingham County?

Southeastern Idaho Public Health provides septic permitting and inspection services for Bingham County, and its local county office is at 145 W Idaho Street in Blackfoot529. A complete application needs the fee, a deed or tax notice, and a signed, dated plot plan drawn to scale30. Every application requires an onsite evaluation, and the owner or applicant must provide test holes 8 to 10 feet deep depending on soil type31. The application page lists $300 for a speculative site evaluation and $925 for a site evaluation plus permit when the site is suitable; fees are subject to change30. About 32.3% of Bingham County soils are rated “not limited” for a conventional drain field; a parcel evaluation is still needed, and a poorer rating does not mean septic is impossible32. Public or central sewer availability can also lead the director to deny an onsite permit33.

Can you live in an RV or tiny home in Bingham County?

Bingham County treats a travel trailer or motor home as temporary housing, not a primary long-term residence6. An RV park is a separate conditional use subject to county and health approvals, so buying acreage does not create a path to use an RV as a permanent dwelling6. A tiny home intended for occupancy is not exempt merely because it is small: Bingham County requires a building permit for any occupied structure1. We could not confirm a special tiny-home occupancy path, a countywide minimum dwelling size, or a complete rule for off-grid sanitation; ask Planning and Development about the dwelling and Southeastern Idaho Public Health about wastewater2830. A HUD-certified manufactured home requires an installation permit before placement and must meet county rules for modifications, additions, and alterations34.

Building a home in Bingham County: the steps, in order

  1. Ask Bingham County Planning and Development to confirm jurisdiction, zoning district, allowed use, lot size, setbacks, and any conditional-use review21262728. In unincorporated Bingham County’s special flood-hazard areas, obtain a floodplain development permit before construction, manufactured-home placement, fill, or other development begins35.
  1. Confirm legal access. Work on a driveway in county public-road right-of-way needs written Public Works authorization before it begins36.
  1. Establish water and wastewater feasibility. IDWR requires a drilling permit and a licensed driller for a well9. Apply to Southeastern Idaho Public Health with the deed or tax notice, scaled plot plan, fee, and test holes30.
  1. Select the county application, create a portal account, attach the required plans and approvals, and submit for staff review; commercial plans need Fire Marshal approval before submission17. After county approval, pay for and print the building permit37.
  1. Obtain separate Idaho permits for regulated electrical, plumbing, and HVAC work12.
  1. Request inspections through the county portal and pass the final inspection; the county issues an occupancy or completion certificate when applicable1618.

What should you check before buying land in Bingham County?

Start with jurisdiction and zoning: county districts govern unincorporated land but exclude tribal land where Bingham County lacks authority, while municipalities and city-impact areas may use different rules221. Confirm the parcel meets the applicable lot-size and setback rules2726. Test wastewater feasibility before purchase; the required onsite evaluation depends on the parcel’s soils31. IDWR requires a permit before drilling a well9. Confirm which agency controls the road frontage: a county-road approach needs Public Works authorization, while a driveway onto state highway right-of-way needs an Idaho Transportation Department encroachment permit3638. For land in a special flood-hazard area, ask Planning and Development about the floodplain development application: scaled plans, elevations, drainage details, and watercourse changes may be required3515.

Watch-outs

  • Starting construction before Bingham County issues the building permit doubles the permit fee11.
  • For a permitted Bingham County project, failing to request an inspection adds 25% of the permit fee; after the second reinspection request, an additional $100/hour charge applies19.
  • An owner doing the owner's own work on the owner's own land may be exempt from contractor registration if there is no intent to sell within 12 months, but applicable building permits, trade permits, zoning approvals, and inspections still remain39.
  • An RV is temporary housing rather than a primary long-term residence in Bingham County; tiny-home standards and off-grid sanitation still require parcel-specific answers from Planning and Development and Southeastern Idaho Public Health640.

Water rights & wells in Bingham County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Idaho’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

Groundwater for domestic purposes up to 13,000 gpd is exempt from permitting; critical-area and moratorium closures generally target new PERMITTED (non-exempt) appropriations, so a household can still drill a domestic-exempt well even inside a critical groundwater area.

Limit: 13,000 gpd (homes, stockwater, irrigation of ≤0.5 acre) under Idaho Code 42-227
