Building an ADU is a major project, and the final bill depends on a few key things. Site prep is a big factor; if your land is sloped or needs extensive utility connections, costs go up. The materials you choose—from siding to kitchen finishes—also change the math significantly. Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.
A dedicated contractor manages the heavy lifting of your ADU project. This involves hiring skilled tradespeople, ordering materials, and ensuring that every phase of construction passes municipal inspections. You need a contractor when you want a single point of contact to oversee the transition from a vacant backyard area to a fully finished, livable home. They bridge the gap between initial architectural designs and the final move-in date for your new space.
