Harold:
The pipe parallel and tight to the box finish wall/ceiling I believe is a Health issue (NSF) for cleaning.
Rated walls & ceilings are limited to 100 square inches, per 100 square feet. Found within the UL White Book. Some info is within the UL for various mfg device boxes.
Putty pads are a solution to boxes on adjacent sides of a rated wall within 24" of each other, or any other penetrations in said wall.
Egress is within NFPA and Building here in NJ
Alarm strobes and pulls are NFPA.
Reno overlooked ADA requirements? Utility Co requirements?
