Prefabricated accessory dwelling unit — Glendale, AZ
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 climate-controlled factory before being transported to your property for final assembly. You might choose this route if you want a faster construction timeline and less disruption to your daily life compared to traditional stick-built projects. Because these are built off-site, local site preparation and utility hookups are still required. Exact pricing confirmed free on the call.
