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
This involves using your secondary unit as a source of monthly income by leasing it to tenants. You might consider this if you want to offset your mortgage or capitalize on high local demand for smaller housing. Success depends on local rental laws and how well the unit is designed for privacy.
