Peder's correct - if you have a building without "internal" divisions like extra doors, even if that building spans multiple tiles, you draw a spawn card for each room in the building as soon as the first door to the building is opened. If you open any further doors, nothing else happens. (Note also that "searching" has nothing to do with it.)If there are special per-scenario rules which would divide a building into multiple buildings (with "wall" markers or internal doors), then yeah, you'd only spawn for the appropriate area once the first door to the area is opened.
