The Bonner County land market

Sandpoint and the lakeshore anchor demand, and out-of-state buyers have pushed prices up. Parcels range from city lots to 5-, 10- and 20-acre rural homesites in the forested hills and valleys, and larger timber tracts. Waterfront and view parcels near Sandpoint and Schweitzer carry the highest prices, while parcels farther toward the Montana line and in the Priest River and Clark Fork areas cost less. Many buyers want to divide a larger parcel, so the county's subdivision rules matter.

Zoning and splitting land

Much unincorporated rural land is zoned Rural 5, with a minimum lot size of five acres. County staff reports show a typical pattern: a 10-acre parcel divided into two lots of about five acres through a short subdivision. Bonner County also has a family exemption that allows one parcel to a family member one time, and a split that creates a parcel under five acres requires a record of survey. Check Bonner County's Title 12 and the planning office before you plan a division, since rules change.

Domestic wells in Idaho

Idaho Code section 42-111 treats domestic water use as exempt from the permit process when total use stays at or under 13,000 gallons per day for homes, livestock and related uses plus irrigation of up to half an acre, with other uses up to 2.8 acre-feet a year. A 2025 law change added limits for subdivisions: a permit can be required for new domestic uses in a subdivision of five or more lots, filed on or after July 1, 2025, in an area under a moratorium or designated as a critical or management groundwater area. Confirm with the Idaho Department of Water Resources whether the planned use and parcel fall within the exemption.
