Expert Accessory Dwelling Unit Construction in Lehi, UT
Accessory dwelling unit construction adds a fully separate living space to your existing property. Black Ridge handles ADU projects across Lehi, Saratoga Springs, Draper, West Jordan, Sandy, American Fork, Eagle Mountain, Bluffdale, Salt Lake, and Alpine. Whether you want a detached backyard unit or an internal apartment with its own entrance, we take your project from drawings to a finished, livable structure. Our owner started this business out of a genuine passion for turning plans on paper into real, three-dimensional spaces — and that focus on craft carries through every ADU we build. Lehi recently updated its detached ADU rules, dropping the minimum lot threshold and requiring the unit to sit at least six feet from the primary home, with owner occupancy of either dwelling. Knowing these local requirements before a single wall goes up keeps your project on track. If you own a qualifying lot in the area and want to add a secondary unit, call us to talk through what your property can support.
