Yes, that’s what we’ve always done in this house. (In upstate NY we actually were even more lax, but that was a different town and time.)
The door from hallway to garage only gets dead bolted when my husband is out of town and I get more cautious. It’s not a a great method, especially now that our area too is experiencing an increase of garage break-ins. So we’ve been discussing the idea of a keypad lock. Husband is also working on a scheme with security cameras.
