Unincorporated Bannock County, Idaho requires a building permit for most construction and applies county zoning to every unincorporated parcel12.

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

Yes. Unincorporated Bannock County requires a building permit to construct, enlarge, alter, repair, move or demolish a building or structure, or to change its occupancy classification1. The county applies the 2018 International Building and Residential Codes along with its other listed construction codes12. Small-work exemptions include flag poles, fences 7 feet high or less, retaining walls 4 feet or less, playground equipment, detached decks under 200 square feet and less than 30 inches above grade, and swimming pools under 5,000 gallons and less than 48 inches deep, but a development permit may still be required13. Habitable space, communication towers and photovoltaic systems always require a building permit1. We could not confirm an owner-builder exemption; ask Planning & Development Services before assuming one applies8.

Who is the Bannock County building department, and how do you reach them?

Bannock County's Office of Planning & Development Services handles county building permits, development permits, zoning review and inspections3. Applications go through the county's online permitting system and must include a signed application, recorded deed, site plan, building plans when required and any applicable outside approvals; incomplete applications are returned13. Review begins with zoning and engineering, followed by building and utility issues when applicable13. The office is at 5500 S. 5th Avenue in Pocatello and is open Monday through Thursday 8 a.m. to 5 p.m. and Friday 8 a.m. to 1 p.m.3. Electrical, plumbing and HVAC permits are issued separately through Idaho's state permit program310.

Does Bannock County have zoning?

Yes. Every parcel in unincorporated Bannock County is subject to the county zoning ordinance; incorporated cities are outside that county rule2. The ordinance publishes an official zoning map and districts for agricultural, rural and suburban residential, recreational, multiple-use, commercial, industrial, special-lands and master-planned areas7. Minimum lot sizes and setbacks are specified by district, and subdivision or lot-of-record provisions can change what applies to a particular parcel56. Land division for development is also regulated under the county subdivision ordinance14. Planning & Development Services is drafting a replacement Land Use & Development Ordinance, so verify the current district, recent annexations or rezones, and parcel-specific dimensional standards before designing or buying37.

How do septic and well permits work in Bannock County?

Bannock County directs septic questions and applicants to Southeastern Idaho Public Health4. Idaho's public health districts administer the state's onsite-sewage rules, but we could not confirm the local septic application sequence from the available county material, so ask the district what approval is needed and when to obtain it154. A new system cannot receive wastewater until the required final installation inspection occurs16. If public or central sewer is reasonably accessible, the district may deny an onsite-system permit and require a sewer connection17. Only 22.3% of county soils rate free of severe limits for a conventional drain field, so arrange a site evaluation before counting on a standard system11. Idaho requires an IDWR drilling permit before drilling a covered well, and the driller must hold an IDWR license9.

Can you live in an RV or tiny home on your land in Bannock County?

We could not confirm a general rule allowing long-term RV living, temporary camping on private land or tiny-home occupancy in unincorporated Bannock County. Every unincorporated parcel is zoned, and district-specific lot and setback standards apply, so ask Planning & Development Services about the parcel and proposed use before moving a unit onto the land26. A tiny home used as habitable space requires a building permit even though the ordinance materials do not address tiny homes by that term1. A newly placed or built structure cannot receive electrical service until a building permit has been secured18. Idaho's camping limits for Fish and Game lands do not answer what is allowed on private property19.

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

  1. Ask Planning & Development Services to confirm the parcel's zoning district, minimum lot size, setbacks and whether a building permit, development permit or both apply756.
  2. Contact Southeastern Idaho Public Health about onsite sewage, or confirm whether an accessible public or central sewer changes the plan417.
  3. Obtain any applicable sewer, floodplain, Army Corps, canal-company or other outside approvals before completing the county submission13.
  4. Submit the signed application, recorded deed, site plan, required building plans and outside approvals through the county's online permitting system13.
  5. Arrange electrical, plumbing and HVAC permits separately through Idaho's state permit program103.
  6. If a driveway connects to a state highway, obtain an Idaho Transportation Department encroachment permit20.
  7. Schedule required inspections; newly built or placed structures cannot receive electrical service before the building permit is secured18.

What to check before you buy land in Bannock County

Check with Planning & Development Services before you buy, since Bannock County's zoning ordinance is currently being rewritten and district-specific rules for a rural parcel may change3. Pull the soil-survey rating for the parcel: only 22.3% of Bannock County's soils rate free of severe limits for a conventional septic drain field, so get an evaluation from Southeastern Idaho Public Health before you count on a standard system11. If the lot needs a well, confirm water availability and the drilling-permit process with the Idaho Department of Water Resources9. Federal land makes up 27.4% of Bannock County, so check whether a parcel borders public land and what access that provides or restricts21. The county sits about 129 miles from the nearest metro area, and the typical property tax bill runs about $1,918 a year at an effective rate near 0.7%222324.

Watch-outs

  • Bannock County is currently rewriting its entire Land Use & Development Ordinance to replace the current zoning code - confirm any zoning answer with Planning & Development Services before you rely on it3.
  • Electrical, plumbing and HVAC permits in Bannock County come from the Idaho Division of Building Safety, not the county building department - budget time to deal with a second permitting office310.

Water rights & wells in Bannock County

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

Actively managed

This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.

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

Idaho Dept of Water Resources — Domestic Exemption ↗

Prior-appropriation state (first in time, first in right). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Idaho state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
