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 follows Idaho state building codes plus local Blaine County zoning. Idaho House Bill 166 protects your right to build an ADU. Wood River Valley ADUs frequently serve premium use cases — guest suites for vacation homes, multigenerational living, and workforce or employee housing for resort-area properties — and command higher rental rates than the Magic Valley average. Bellevue properties may involve design review, floodplain considerations, or hillside overlays; we confirm setbacks, design requirements, and any overlay zones during the Feasibility Check.

Idaho HB166 Protects Your Right to Build
Idaho House Bill 166 prohibits any city or county from imposing an outright ban on accessory dwelling units. That means Bellevue must have a permit process for ADUs — and as of July 2023, your HOA cannot block you either (on owner-occupied properties). Learn more about Idaho ADU law →
