I jumped to the conclusion because of the lack of gas meter and the lack of cooking range. Based on my experience and what I observed with a friend’s rental.

But you’re right – the rules are different for different jurisdictions. I’m very familiar with San Diego’s rules for accessory buildings, but a lot less familiar with other places… other than some of the ways they differ from SD.

We were surprised that we couldn’t get the gas meter till the city issued occupancy. But that is apparently done to prevent folks from occupying early.
