For a remodel in this high rise the contractor used PT lumber to frame out for the tub. Would you allow this? Code citation or approved?

The glass is hurricane impact glass. This thread is about the wood

I’d say no per Section 718.5 (2018 IBC).

Is it treated per section 603.1, Florida Building Code?

I might say OK to the framing supporting the tub. not much more that a cabinet. However the wood framed wall is a definite no

I'd rather see pressure treated lumber than light gauge steel around water and electricity.

FRT wood-framed partitions are permitted per Section 603.1, but what is being shown are concealed spaces--not partitions--around the tub; thus, Section 718.5 comes into play. In my opinion, that's the code in the strictest sense, but I agree that the extent and context of the wood framing do not really create an extensive fire risk as long as the wood is FRT.
How is a concealed space under a tub enclosure any different than the “concealed space” in a partition wall, that is not filled with insulation?
And I’m not sure this is concealed space ... there will be access panels to get to the jacuzzi equipment.

Obviously the floor was not a PT slab.

the wall is metal. The wood is there for the door frame only

Cabinet definition - a case or cupboard usually having doors and shelves
Case definition - a box or receptacle for holding something
It's just a giant sink base cabinet. That's all. APPROVED

IBC 603.1#6 (Millwork such as doors, door frames, window sashes and frames.) and #14 (Blocking such as for handrails, millwork, cabinets and window and door frames.) permits frames and blocking respectively. To me, that appears to be a trimmer stud at the door opening, and the tub surround is absolutely framing.
Use FR treated per 603.1#1.1 (Nonbearing partitions where the required fire-resistance-rating is 2 hours or less.).

Does the space need sprinklers per NFPA 13?

It is the issue of the volume of open space and potential electrical/ fire hazards - wall stud cavities if you do the math tend to be less than 100 SF. (16" x 96 inches by 3.5" / 144)

We treat these spaces the same as furniture, provided they are distinct spaces from the building construction.

How big does it have to be to be considered?

We don't have a clear line in the sand about it. Mostly at the discretion of the inspector.

Does the building have fire sprinklers? if it is, then the area or framing behind the tub does not meet the exception for not providing fire sprinklers - I see open wall studs behind the void space shown in the picture - DWV PVC piping and water distribution lines
