Areas We Serve

Based in San Diego.
Serving Southern California.

Based in San Diego. Serving Southern California and select California markets. San Diego County is home — it's where Casita started and where we've worked in every jurisdiction. We now take ADU projects in Orange County, Riverside County and the Inland Empire, and Los Angeles County, and we're adding California markets as we grow.

Wherever the project is, the process is the same: The Casita Way Design. Bid. Build.
