Rule of thumbMandatory
No overlapping fixtures
FIX-FIXTURE-OVERLAP-01Description
No two fixtures within the same room may overlap in footprint (AABB intersection > 0).
Why this exists
Two fixtures in the same room can't share floor space — a tub on top of a toilet doesn't pass code or common sense.
