Building an ADU in Idaho with HiLine Homes
An Accessory Dwelling Unit (ADU) is a custom-built living space designed to complement an existing property. HiLine Homes has been operating as an experienced ADU builder and custom home contractor in Idaho for nearly 30 years, offering construction services that aim to fit a homeowner's property, lifestyle, and practical needs.
ADUs offer a range of benefits for homeowners. As a separate but connected living space, an ADU can serve multiple purposes:
- Generating monthly rental income as an independent unit
- Providing a close but private space for adult children, aging parents, or guests
- Functioning as a home office or studio
- Contributing to long-term property equity and resale value
Attached and Detached ADU Options
HiLine Homes offers both attached and detached ADU designs to accommodate different property types and family situations. Attached ADUs are suited to homeowners who want convenient access between the main home and the additional unit while still maintaining a degree of privacy. Detached ADU designs provide full separation, making them a practical option for rental income, guest accommodations, or multigenerational living arrangements.
As part of their service, HiLine Homes also provides guidance on navigating Idaho building codes and permitting requirements. With experience across Idaho, Oregon, Washington, and Northern California, their team is familiar with the construction standards and zoning considerations that apply in different regions.
HiLine Homes works across a variety of Idaho locations, including:
- Urban areas such as Boise, Pocatello, and Twin Falls, where ADUs help maximize limited lot space
- University towns like Lewiston and Moscow, where ADUs can attract student or faculty tenants
- Rural communities such as Stanley, Blackfoot, and Magic Valley, where detached ADUs offer independent living for family members or caregivers
ADU Floor Plans and Financing
HiLine Homes offers a selection of custom ADU floor plans that can be tailored to a homeowner's property layout, budget, and lifestyle. Notable options include:
- Home Plan 800 — An 800-square-foot plan featuring a large living room, dining area, laundry room, and a primary bedroom with a walk-in closet.
- Home Plan 500A — A plan with a spacious Great Room and kitchen with vaulted ceilings, plus a covered front porch.
- Home Plan 500B — Designed for an attached ADU, this plan includes a private bedroom and an open Great Room with vaulted ceilings, intended to blend with a main HiLine home.
For homeowners considering the financial side of an ADU project, HiLine Homes works with a network of Approved Lenders who offer construction loans with up to 100% financing for custom homes and ADUs. A prequalification process is available to help homeowners understand which financing options may apply to their situation.
Overall, HiLine Homes positions itself as a full-service ADU contractor in Idaho, handling construction, design customization, permitting guidance, and financing support as part of their building program. Homeowners interested in adding a detached ADU, in-law suite, or attached unit to their property can schedule a consultation to explore available options for their specific lot and location.
