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
An accessory dwelling unit permit is the required authorization from your local planning department to build on your lot. This paperwork confirms your plans follow zoning rules and structural safety standards. You need this service if you are in the planning stages of your backyard project.
