Build Smarter: Accessory Dwelling Units in the Tri-Cities

Looking to expand your living space or generate extra income from your property? An accessory dwelling unit (ADU) might be the perfect solution. At JLS Consulting and Contracting, we specialize in building custom ADUs that serve real-life needs whether it’s for multigenerational living, a rental unit, or a private guest house. Based in the Tri-Cities, we help homeowners design and build high-quality accessory dwellings that meet local code and match the function and flow of their existing homes.

Practical ADU Construction Backed by Experience

ADUs require more than basic construction; they demand careful planning, permitting knowledge, and an understanding of how to maximize small spaces. At JLS, we bring years of experience working with Tri-Cities homeowners to create ADUs that are both functional and well-built. We manage everything from the first site visit to final inspection, including drafting floor plans, submitting permit applications, managing utility connections, and overseeing the build. Whether it’s a detached backyard cottage or an attached in-law suite, we work to ensure every project meets your goals and fits your lot.
