Buying Land in Bannock County, Idaho

A 1998 zoning ordinance that's actively being rewritten -- the rules on the ground could change under you

Bannock County's unincorporated land is currently zoned under Ordinance No. 1998-1, which implements the county's 1995 comprehensive plan (known locally as "Bannock County Second Century"). Bannock County Planning & Development has been working since late 2025 to replace it with a single, consolidated Land Use and Development Ordinance (LUDO). The most consequential piece for rural-acreage buyers: a 2024 countywide ban on large-scale solar and wind projects that the LUDO draft could reverse via conditional use permit. For the ban's history, the proposed CUP requirements, and the rewrite's current status, see the dedicated wind-solar-leasing page below.

Fort Hall Indian Reservation: some county land is tribal trust land, not ordinary fee land

The Fort Hall Indian Reservation -- home to the federally recognized Shoshone-Bannock Tribes -- overlaps Bannock County alongside Bingham, Power, and Caribou counties, and roughly 97% of reservation land is reported as tribally or individually-Indian owned and held in federal trust rather than conventional fee-simple property. If a parcel falls within the reservation's exterior boundary, its trust-vs-fee status determines which government -- Bannock County or the Tribes -- actually governs land use on it. See the dedicated tribal-trust-land-status page below for how that jurisdiction works in practice, and for the reservation's fractionated-ownership complications.

Zoning districts, minimum lot sizes, and the quarter-quarter-section rule for unincorporated land

Setting the LUDO rewrite aside, Ordinance No. 1998-1's existing zoning map divides unincorporated Bannock County into a set of named districts -- Agricultural (A), Residential Rural, Residential Suburban, Single-Family Residential (R-1), Multi-Family Residential (R-2), commercial districts, Light Industrial & Wholesale (LIW), Industrial (I), Special Lands (SL), and Master Planned Community (MPC) -- each with its own minimum lot size and permitted-use list. In the Residential Rural district, the baseline minimum lot size is five acres for a conventional subdivision relying on an individual well and septic system, and the county's Health Department can require a larger lot where soil or water conditions warrant it. The Agricultural district works differently: it allows one dwelling unit per quarter-quarter section (roughly 40 acres) of land in single ownership, up to four quarter-quarter sections (about 160 acres), but also permits smaller, clustered lots -- as small as one acre -- in an open-space subdivision that sets aside the remaining acreage. A bona fide farm, ranch, or dairy operation on a parcel of at least 10 acres can add up to two more dwelling units beyond that baseline for people employed in the operation.

Separately, the county's Subdivision Ordinance No. 1997-4 defines a 'subdivision' as dividing land into parcels smaller than, or laid out differently from, a standard quarter-quarter section for a non-agricultural purpose, or splitting one parcel into two or more -- so a straightforward split of raw acreage for agricultural use can fall outside subdivision review entirely, while the same split for a home site typically does not. Before assuming a parcel can simply be divided along quarter-quarter lines, confirm its current zoning district, minimum lot size, and whether your intended split or use triggers subdivision review with Bannock County Planning & Development directly.

Power, agriculture, and public land: a few more county-specific facts worth knowing

Bannock County is served by Idaho Power, an investor-owned utility headquartered in Boise -- not one of the member-owned rural electric cooperatives that serve many other rural Idaho counties -- so confirm service and any extension costs for a specific rural parcel directly with Idaho Power rather than assuming co-op billing or membership rules apply. Agriculture remains a genuine part of the county's economy alongside Pocatello's education, healthcare, and manufacturing base: the Portneuf Valley's irrigated farmland, fed historically by Snake River water, supports potatoes, grain, and alfalfa, and University of Idaho Extension's Bannock County office continues to serve local growers and processors as part of eastern Idaho's broader potato-growing region.

For buyers drawn to acreage near public land, the Caribou-Targhee National Forest's Westside Ranger District borders the county's southern edge in the Bannock Range, including the Scout Mountain area about 13 miles south of Pocatello -- a popular Forest Service recreation site (elevation roughly 6,900 feet) with hiking, mountain biking, horseback, and dirt-biking trails, and the nearby Mink Creek drainage is known locally for birding. National Forest boundaries and access points can run directly against private rural parcels in this part of the county, so confirm a specific property's boundary against Forest Service land, not just its general proximity, before assuming public-land access.
