Scope of Work
Structural & Rough-In
| Task | Description |
|---|---|
| Floor Leveling & Insulation | Level the garage floor (raise if needed), install moisture barrier, and insulate the floor to meet residential energy code. |
| Garage Door Removal & Wall | Remove the garage door and build a framed, insulated wall with a window or entry door in its place. |
| Wall Insulation & Framing | Fur out or frame exterior walls and insulate to residential code. Add any interior partition walls. |
| Electrical & HVAC Rough-In | Run electrical circuits, outlets, and lighting per residential code. Extend or add HVAC supply and return to the space. |
Drywall & Systems
| Task | Description |
|---|---|
| Drywall | Hang, tape, mud, and sand drywall on all walls and ceiling. Maintain fire separation where required (garage-adjacent walls). |
| Plumbing (if applicable) | Rough in and finish plumbing for bathroom, kitchenette, or laundry if part of the conversion scope. |
| Window & Door Install | Install egress windows, entry door, and any additional windows for light and ventilation. Meet code minimums. |
