About Us

San Diego's Most
Trusted ADU Builder

My name is Juan Moreno, and I've spent the last 12 years building luxury ADUs across San Diego County. What started as a passion for architecture and craftsmanship has grown into the most trusted ADU company in the region.

When you work with 5 Star ADU, you're not handing your project to a salesperson and hoping for the best. I'm personally involved in every project — from the first consultation to the final walkthrough.

Owner-Led Every Step of the Way
Juan oversees every phase of construction personally. You'll have direct access to the person building your ADU, not a call center.
100% Permit Approval Record
We know San Diego's permitting process inside and out. Every project we've submitted has been approved — zero rejections, zero delays.
Luxury Finishes at Every Price Point
We believe quality shouldn't be a premium add-on. Our standard builds include the finishes competitors charge extra for.
On-Time. On-Budget. Always.
Our timeline transparency and detailed contracts mean no surprises. We've completed 150+ projects with zero budget overruns.
