Tips

Millcreek zoning requires minimum off-street parking — verify you can still meet the requirement after conversion.
The garage slab is typically 4 inches lower than the house floor — you may need to raise the floor for ADA and threshold compliance.
Fire separation between a converted garage and the house (1-hour if adjacent to habitable space) must be maintained.
Garage conversions to bedrooms require egress windows — plan for this before closing the garage door opening.
