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 prefab ADU is built in a factory and then transported to your property for final assembly. These units are often faster to build than traditional construction because the work happens in a controlled environment. If you want to minimize noise and debris on your property or need a quicker turnaround for your backyard space, this is a great option.

While both offer extra living space, an accessory dwelling unit (ADU) in Fort Worth is legally defined and must meet specific city zoning requirements. It's often built as a permanent addition to your property, like a detached unit or an attached in-law suite.
