Ok, I’m looking at a ground floor apartment in a fourplex with one unit above.
The building was built 1928.
The upstairs unit is not touched.
A ground floor unit is under a near gut renovation.
There’s a code enforcement case, so now they have to get it inspected.
The contractor has cut 3" holes in the lath and plaster ceiling for LED can lights with wings:
What should I write up about this situation? The lathe and plaster ceiling is itself only barely fire rated (some tests were done in 1910 or so that are only basis for rating such ceilings). Yet with holes, whatever actual fire resistance the ceiling once had is long gone.
CBC 402.4.2.1 Tenant separations
Each tenant space shall be separated from other tenant spaces by a fire partition complying with Section 708. A tenant separation wall is not required between any tenant space and the mall.
CBC 714.3.2 Membrane Penetrations
Membrane penetrations shall comply with Section 714.3.1. Where walls or partitions are required to have a fire-resistance rating, recessed fixtures shall be installed such that the required fire-resistance will not be reduced.
I see Allied molded old work electrical boxes in fiberglass reinforced polyester (FRP), such as R9305-SK
But these don’t appear to be very suitable for running the can light wire or clip.
How would you write this up?
Is it clearly a “problem”?
What product might work to fix it?
