ADU Services

ProStruct Engineering offers dedicated structural engineering services for ADU projects, including:

• Detached ADU structural engineering

• Attached ADU structural engineering

• Garage conversion engineering

• Junior ADU (JADU) engineering

• Foundation design and calculations

• Structural framing plans

• Load-bearing wall analysis

• Structural calculations and PE-stamped drawings

• Permit-ready engineering documentation

The company also works with a network of architects and design partners for clients who do not yet have architectural plans. Its primary role is to provide the structural and civil engineering required to support ADU development, rather than independently deliver a complete design-build project.
