Bringing Honesty and Heart to ADUs Based on Trust
The ADU Dudes was created with one simple mission: help consult, coordinate and deliver reliable, affordable, high-quality ADU and home additions with full transparency and zero headaches.
With construction by San Andres Construction (License #1081083), our team has built a reputation across the Bay Area for craftsmanship, honesty, and a commitment to doing things the right way — every time.
​
Whether you’re adding an in-law unit, creating rental income, expanding space for family, or building a full 3-bedroom ADU, we make the entire process smooth, clear, and efficient from start to finish.​
