What affects the price
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.
About this service
A prefab ADU is built in a controlled factory setting and then transported to your property for installation. This approach can be faster than traditional on-site building and often involves less mess in your backyard. You should consider this if you prefer a streamlined process and a predictable timeline. Factors like site accessibility for delivery trucks typically influence the feasibility and total cost. Exact pricing confirmed free on the call.
