Do you a permit that is the first thing you need and a garage is not a living space so that will need to be addressed this will be an expensive project

That is not wise. Converted garages are never a good idea. I would come up with a better plan.

a converted garage can be an excellent idea, but its not a trivial project. just don't be tempted to have the floor lower than the existing part of your bedroom, i kicked myself endlessly that i did a step down to get more headroom.

the original too-small garage was on the left, we added the new one on the right. excuse the dated decor, that was our staged listing picture from 7 years ago.

thanks...we moved away 7 years ago to this charmer and have no garage at all.
