Prefab adu — Pomona, CA
Last updated: September 24, 2026
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 prefab ADU is built in a controlled factory environment and then transported to your property for final assembly. Because the units are constructed off-site, they often result in less noise and debris in your yard during the process. You need this if you want a more predictable timeline and efficient construction process. Exact pricing confirmed free on the call.
