Structural Requirements: Foundations, Plumbing, and HVAC
Builders did not originally design old garages for full-time living. You must upgrade the concrete foundation and wooden wall framing. Plumbers need to trench and run new water and sewer lines.
HVAC systems require proper wall insulation for year-round climate control. Lafayette experiences cold winter nights and very hot summer days. Proper climate control is vital for tenant or family comfort. We install energy-efficient mini-split systems for optimal temperature management.
Comparing Attached and Detached Garage ADUs
You must choose between attached or detached structures for conversion. Each architectural option provides unique benefits for your specific property. A detached garage conversion cost is often slightly higher overall.
This price difference comes from separate utility trenching needs mostly. However, detached units offer much more privacy for the occupants. Attached units are often cheaper to hook up to utilities. You can share existing plumbing lines easily through shared walls.
| Feature | Attached ADU | Detached ADU |
|———|————–|————–|
| Privacy Level | Moderate Privacy | High Privacy |
| Overall Cost | Generally Lower | Generally Higher |
| Utility Lines | Shared Connections | Separate Trenching |
| Setup Time | Faster Timeline | Longer Timeline |
