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
Turning an ADU into a rental property means converting your extra space into a standalone apartment for tenants. This is a smart way to generate monthly income or help pay down your mortgage. You need this service if your local zoning allows for rental units and you have the extra square footage available.

Modular ADUs can offer advantages like faster construction times and potentially more consistent quality control due to factory production. They must still meet all local building codes and zoning requirements for places like Corpus Christi. A builder experienced with modular construction can guide you through this option.
