ADU Builders

Accessory Dwelling Units Designed for Real Life and Long-Term Value

An accessory dwelling unit is one of the most flexible additions a homeowner can make to their property. Whether you are planning space for family, long-term rental income, or future flexibility, an ADU needs to be thoughtfully planned and built to work within local requirements and your long-term goals. Star Builders LLC designs and builds ADUs for homeowners throughout Salem and the Mid Willamette Valley, helping clients navigate layout decisions, site constraints, and construction details so the finished space is functional, durable, and compliant.

Trusted ADU Builders for Salem Homeowners

ADU projects come with unique challenges around zoning, access, utilities, and space limitations. Homeowners choose Star Builders because we keep these projects organized, explain requirements clearly, and stay involved from planning through final walkthrough.

ADU Feasibility and Site Evaluation

We help homeowners understand whether ADU is feasible on their property before plans move forward. This includes evaluating lot size, setbacks, access, utilities, parking requirements, and how the unit can be placed on the site.

Custom ADU Layouts & Design Planning

ADUs require smart use of space. We design layouts that feel comfortable and livable, balancing efficiency with storage, natural light, and privacy.

Detached and Attached ADU Construction

Whether the unit is detached, attached, or converted from existing space, construction is handled with durability, code compliance, and long-term performance in mind.

Interior Build-Out and Finishes

We coordinate interior construction so the ADU feels complete and well-built. This includes insulation, moisture control, drywall, flooring, cabinetry, kitchens, bathrooms, and finish details.
