Bonner County, ID Building Setbacks & Zoning: Setback Rules (2026)

Section 12-411, Table 4-1, covers the F, A/F-20, A/F-10, R-10 and R-5 zones. Every one of those columns prints a 25 foot minimum street setback and a 25 foot minimum property line setback, plus a 25 foot setback for on premises signs and a 35 percent maximum lot coverage. Exceptions follow the table. Note (11) lets legal nonconforming lots cut the property line setback to 5 feet when the lot is less than one (1) acre, and to 10 feet when it is larger than 1 acre but less than 5 acres, provided snow storage and stormwater are accommodated on the site.

Note (13) sets agricultural buildings and other nonresidential structures at no less than 40 feet from property lines, reducible to 50 percent of that requirement with approved screening, and at 5 feet for agricultural buildings used solely for growing and harvesting crops. Note (10) lets utility structures not exceeding 30 square feet, such as well houses, sit within the required street setback. Note (12) states that setbacks do not exempt landowners from deeded restrictions or recorded easement boundaries. Section 12-412, Table 4-2, covers S, C, I, RSC, REC and AV.

The property line setback prints as 5 feet in S, C, I, RSC and REC and 15 feet in AV, note (12) raises it to 20 feet where the lot abuts land in the A/F district, the Suburban street setback is 25 feet, and first-floor porches and decks open and unenclosed on three sides can project up to 8 feet into a street setback. Shoreline setbacks under section 12-711 apply in all zoning districts: no structure closer than forty feet (40') from the shoreline of lakes, sloughs, ponds, the Clark Fork or Pend Oreille rivers and mapped intermittent streams, and seventy five feet (75') from other rivers, streams and creeks.
