Older garages were built to store cars, not people. The gap between those two jobs is where conversion cost hides: a slab that was never meant as a living-space floor, electrical service sized for a opener and a light, walls with little or no insulation, and a structure that may never have been permitted.
None of this makes an older garage a bad candidate. It makes the pre-conversion inspection the most valuable step in the project, because it turns unknown conditions into a priced scope instead of mid-project surprises.
What to have checked first
- Slab: level, cracks, moisture, and whether it meets living-space requirements.
- Electrical: panel capacity and whether new circuits are needed for heating, lighting, and outlets.
- Insulation and heating: walls, ceiling, and how the space will actually stay comfortable.
- Structure: roof, framing, and whether the building was permitted when built.
- Access and egress: how the finished room is entered, and whether that works for daily use.
Questions people ask
Can a conversion keep the garage door?
Sometimes, with the door fixed in place and insulated behind it, but that depends on the design and on current rules — ask the builder, and do not assume it.
What is the most common surprise?
Slab and electrical work. Both are invisible from the driveway and both can change the scope significantly, which is why they belong in the inspection, not the contingency.
