Accessory dwelling unit builders — Glendale, AZ

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
These are specialized contractors who focus specifically on the design and assembly of secondary housing units. Unlike general contractors who take on all home renovations, these specialists understand the unique constraints of building in backyards or converting existing structures. You need them when you want someone who manages the entire process—including permits and site management—specifically to ensure your ADU is built efficiently, correctly, and according to the specific regulations governing secondary structures on residential lots.
