Detached accessory dwelling unit — West Valley City, UT
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
A detached ADU is a standalone building separate from your main home, like a backyard cottage. These provide the most privacy for you or your tenants since there are no shared walls. You need this if you have a large enough yard to accommodate a separate structure.
