Step 5: Construction (where planning pays off)
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.
