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.

About this service

A modular ADU is built in a factory and then transported to your property to be assembled on a foundation. You should consider this if you want a faster construction timeline and less disruption in your backyard. Because the units are built off-site, they are often cost-effective and efficient. We help you choose the right model and ensure the site is ready for delivery. Exact pricing confirmed free on the call.
