Twin Homes

Twin Homes in Coeur d'Alene

What are twin homes? Twin homes (sometimes called duplexes with separate ownership) are two single-family dwelling units that share a common wall but sit on individually owned lots. Each unit has its own entrance, utilities, and fee-simple ownership, giving buyers the benefits of single-family home ownership with a more affordable price point. They provide an important “missing middle” housing option—more density than a traditional detached single-family home, but without the shared walls and maintenance of condominiums.

Twin homes can help address housing affordability by reducing land costs per household while maintaining a residential character that fits many neighborhoods.

City Staff Work on Twin Homes Planning & Zoning staff are actively reviewing twin home development standards for Coeur d’Alene. The goal is to create clear, objective guidelines that support attainable housing while protecting neighborhood character, public safety, and long-term livability. Staff will bring forward recommendations to the Planning Commission and City Council for consideration in the coming months. Public input will be welcomed during the review process.

Update on Idaho State Legislation (2026 Session)

During the 2026 Idaho Legislative Session, lawmakers considered several housing-related bills aimed at increasing supply and reducing regulatory barriers. Senate Bill 1353 (SB 1353), sponsored by Sen. Ben Toews (R-Coeur d’Alene), sought to limit local restrictions on twin homes and duplexes in cities with populations over 10,000. The bill would have required cities to allow these housing types in single-family residential zones, with provisions for administrative approval and limits on certain local standards.

The Senate passed an amended version of SB 1353 on March 20, 2026 (23-12 vote). However, the bill faced significant debate in the House, particularly around local control, infrastructure capacity, and compatibility with existing neighborhoods. The House Business Committee ultimately did not advance the measure, effectively stopping SB 1353 from becoming law this session.

Similar housing bills addressing starter home subdivisions and accessory dwelling units saw mixed outcomes, with some passing and others stalling or being significantly modified. The Legislature adjourned without enacting the broader preemption language originally proposed in SB 1353.

City staff will continue monitoring state housing policy and will keep the community informed of any future legislative or local developments that may affect housing options in Coeur d’Alene.
