YEAR ESTABLISHED

Dedicated to ADU Excellence.

We turned the worst day of our lives into a mission to build homes that actually work for real families, especially those with mobility challenges.

After a life-changing hit-and-run in 2024 that left my wife & I both fighting to walk again, we decided no family should ever feel stuck in a house that doesn’t fit them. We recommend all projects to install wider doors, smoother transitions, and thoughtful details most contractors never think about — because we live it every single day. 

When you hire Cal Capitol, you’re not just getting a contractor. You’re getting a team that’s been through the fire and came out building better homes for everyone.
Ready to turn your backyard into income, independence, or both?
Let’s talk — your project deserves a builder who gets it.
