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.

How much does an ADU cost in Texas?

What are the rules for ADUs in California?
California has state laws that promote ADUs, often allowing them by right if they meet size and setback standards. Local jurisdictions still have input, but state law establishes a baseline. This differs from how Texas cities like Irving may regulate ADUs.
California has offered grants to help reduce the cost of ADU construction, especially for affordable housing initiatives. These programs can significantly lower the initial financial burden for homeowners. This is a California-specific program and not applicable in Texas.
