Permit-able Residential Dwelling Plan Requirements

[Rob Tucker]

I've dealt with the code for decades and I can't answer your question with any accuracy. Never had need or interest but...

There are (or were) sections of the code that handled minimum room sizes. You kind of have to read it carefully and then could still be wrong. My suggestion, if you really want to know the absolute minimal home requirements, is to ask the building department. It is their job to know such things. I would also suggest you make your inquiry in writing. A written inquiry requires a written response. A written response is better than later arguing that "someone told me.....".
