Our Basement Remodeling Process

Our proven process helps ensure a smooth and predictable remodeling experience from consultation to completion.

We start with a free in-home consultation to learn about your goals, discuss your budget, evaluate your basement, and explore options for creating a functional apartment or ADU.

Together, we’ll develop a layout that makes the most of your available space while incorporating the bedrooms, bathrooms, kitchen, storage, and living areas you need.

Our team manages the permitting process and coordinates with local building departments to help ensure your basement apartment meets applicable building and safety requirements.

Once construction begins, our experienced crews complete each phase of the project while we coordinate inspections, monitor progress, and keep you informed throughout the process.

After construction is complete, we’ll conduct a final walkthrough with you, address any remaining details, and ensure your new basement apartment is ready to enjoy.
