Support for our Customers

While the recent shutdowns have thrown uncertainty into most people’s business and development plans, the good news is that the California State government has officially deemed construction to be an “essential service,” and projects across the state are moving forward.

This includes ADU projects.  We at USModular want you to know we are open for business and supporting our many customers during this time.
