“Electrical service is the most common budget surprise in garage conversions. Most detached garages have a 20-amp subpanel fed by a small wire from the house. A full ADU needs a 100-amp subpanel with dedicated circuits for kitchen, bath, HVAC, and EV charging. The electrical upgrade alone often runs $6–12K. Always get an electrical assessment early.”

Pro Tip

Run conduit for future EV charging during the conversion, even if you're not installing a charger now. A 1-inch conduit from the garage subpanel to the exterior of the building costs $200–300 during construction. Retrofitting conduit after the walls are closed costs $1,500–3,000. Pre-run the conduit and cap the ends; charge when ready.
