Step 5: Construction (where planning pays off)

By Cali Dream Construction | January 09, 2026 | San Diego

ADU construction typically includes:

• Site prep and foundations

• Framing and roof

• Rough plumbing, electrical, HVAC

• Insulation + drywall

• Cabinets, tile, flooring, fixtures

• Final inspections and closeout

A clean scope and selection plan keeps the build moving. The biggest delays usually come from late decisions or long-lead materials.
