When building your own home, one of the items you are going to want to check thoroughly during the framing stage of construction is that the fire- and draft-stops are installed as required.
Acceptable fire-stop material includes: 1/2″ sheetrock, 2x dimensional lumber with joints backed by 2x lumber; one thickness of 23/32″ thickness structural panel
Checklist for fire- and draft-stop when building a house.
- 9-foot walls and taller – solid blocking in every studbay of the upper half of the wall
- Furrdowns – typical location is at kitchen cabinet tops when the venthood is ducted to the outside
- Return air shafts -
- Fireplace & chimney – install at first- and second-floor topplates.
- Cricket must be fireblocked from the attic.
- Maintain 2″ between chimney flue and combustibles
- Stair well – Concealed spaces between stringers at top & bottom of run
- Vents, pipes & ducts (at ceiling and floor level)
- Covered walk between home and detached garage – at garage end or mid-span to home.

I got pissed off at these annoying neighbors so I trapped them to remove them from the game. Satisfying!
