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.

What is a prefabricated ADU, and is it an option in Bellevue?

A prefabricated ADU, or prefab ADU, is built off-site in a factory and then transported to your Bellevue property for assembly. This method can sometimes speed up the construction timeline. Prefabricated units offer a controlled building environment, potentially leading to consistent quality. The pros can discuss if this option suits your site and design preferences.
