Do I need permits for garage insulation?
Insulation alone usually does not. Once you condition the space and call it habitable — drywall, finished floor, mini split — that's an ADU or conversion permit and triggers Title 24. We can produce the insulation specs your plan reviewer needs.
Is a garage door insulation kit worth it?
It helps, but it is not a substitute for wall and ceiling insulation. The door is roughly 15 to 20 percent of the envelope. If the rest of the box leaks, the door kit can't carry the load alone. We usually do all three together for ADUs.
