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
In San Diego, an ADU contractor understands the specific coastal commission rules, fire safety codes, and local density incentives that apply to your property. Because regulations here are quite specific, you need a contractor who is experienced with local planning departments to avoid delays. Whether you are adding a unit in a hilly area or a flat lot, a local pro helps ensure your project stays compliant with all regional requirements from day one.
