But, like they said, if you go over 8 total rooms you divide by 2 and round down to the lower whole number to get the bedroom count for Title 5 purposes, or you put a 4 bedroom deed restriction on the property. Now, if the town catches the room count is another story, some would and others wouldn't. I'd guess that your system is sized for 4 bedrooms, my experience with new construction is 4 is pretty standard, you only see 5 or more if you are in a wealthy area where the extra bedroom has a bigger return.
