Adu unit — Torrance, CA
Last updated: September 24, 2026
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 ADU unit is a secondary housing structure located on the same lot as a primary home. Whether you need a home office, a gym, or a guest house, an ADU adds functional square footage to your land. You need this when you run out of space inside your main house but don't want to move.
