Rule of thumbMandatory
Every room reachable from front door
CIR-CONNECTIVITY-01Description
Every habitable room and bathroom must be reachable from the front entry through opening-connections — no isolated rooms.
Why this exists
If a room can't be reached without leaving the house, it isn't part of the house. Reachability from the front door via interior doors is the most basic plan integrity check.
