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.
Getting an ADU permit is the legal process of obtaining local government approval for your building project. You cannot legally construct or occupy an ADU without this documentation. You need this service before any construction begins to ensure your build meets building codes and safety regulations.
