While we are digressing and having fun, I can't see how the garage becomes a conditioned living space... unless... it has been converted, e.g., close up the vents and seal off the drive-in door. I've seen where enclosed patios became condiitioned living spaces because I used to build them back in the crazy days of the 80's when you could get a tax credit by installing a sun room with a tile or concrete floor that qualified as a solar heating device coupled with a through-the-wall fan. Obviously said room needed windows to let the light in and hold the heat and these had a tinted but transparent plastic roof. They were literally hot houses.
Here's the kicker, the feds only wanted the sun and room while the state said all such rooms had to remain 60% open on 2 walls. Screens OK but no windows glass, plastic or otherwise. So we built the rooms, got signed off and took the windows out of storage and installed them for pics for the federal tax credit.
Kicker #2, now remove the typical slider that went from the house interior to the new 'patio' and it becomes a room. Can't build a 'room' w/o the usual footings, engineering, and now energy calcs, blah, blah.
The tax credit disappeared and so did 95% of the companies building the enclosed patios. So, I know a bit about conditioned live space. I know we're way OT but how in the world did the AHJ decide your garage was a CLS?
