ADU Contractor in Bellevue, Idaho
Twin Falls ADU Guys serves the Wood River Valley — including Bellevue homeowners building in-law suites, rental units, and detached ADUs.
ADU Services in Bellevue
Bellevue is the southern gateway to the Wood River Valley, ~75 miles north of Twin Falls along ID-75. We travel north for Bellevue ADU projects because the market is real — Wood River Valley property values support ADUs as both rental investments and accessory living for family. Bellevue contracts building inspections through SAFEbuilt and coordinates land-use matters with Blaine County, so the permit path can involve more than one office. We know how to navigate it.
Permitting in Bellevue
Bellevue (population ~2,400) is under 10,000, so the SB 1354 mandate does not bind it — ADU permissibility depends on Bellevue's local zoning and Blaine County. Wood River Valley ADUs frequently serve premium use cases — guest suites for vacation homes, multigenerational living, and workforce housing — and command higher rents than the Magic Valley average. Bellevue properties may involve design review, floodplain, or hillside overlays; we confirm setbacks, design requirements, and overlay zones during the Feasibility Check.
ADU Rules in Bellevue
Local code governsBellevue (population ~2,400) is under the 10,000 SB 1354 threshold, so no statewide law compels it to allow ADUs. ADU permissibility depends on the City of Bellevue's local zoning code and Blaine County rules — we verify it for your parcel.

Idaho ADU Law and Bellevue
Bellevue is under 10,000 population, so the Idaho SB 1354 ADU mandate does not bind it — whether you can build an ADU is governed by the local zoning code. That is exactly what our Feasibility Check verifies for your parcel. (Idaho HB 166 separately protects an internal ADU on an owner-occupied homestead from HOA bans.) Learn more about Idaho ADU law →
