Assembly requires equipment and basic construction experience, but many owners-builders complete their projects without a general contractor. Faster build times and lower operating costs enhance your return.

General contractors experienced with ADUs understand the unique challenges of small-scale construction, local regulations, and efficient space planning. Look for contractors who’ve built multiple ADUs and can provide references from recent projects. Ask to visit completed ADUs they’ve built—this reveals quality and design creativity.
