What affects the price
Building an ADU involves several moving parts that shape your total budget. The biggest factor is whether you choose a prefabricated unit or a custom build on-site. Site preparation is also significant; if your land requires extensive grading, utility trenching, or foundation work, costs will climb. Your choice of finishes—like kitchen cabinetry, flooring, and siding materials—also shifts the bottom line. We help you navigate these variables to find a setup that fits your property. Exact pricing confirmed free on the call.

What is an accessory dwelling unit?
An accessory dwelling unit (ADU) is a second, smaller housing unit on a single-family home lot. It provides independent living space with its own kitchen, bathroom, and entrance. ADUs can be attached to the main house, such as a basement or garage conversion, or be a detached structure like a backyard cottage. They are designed to offer flexible housing solutions for families or as rental income properties. ADUs are a practical way to increase housing density.
