Existing 2"x8' joists between residential units need rating...
Hi there,
I am working on a project where we are converting a single family dwelling into two separate units. It is quite a narrow house; and the existing floor joists at the rear, narrower section of the house are 2"x8".
The Building Plans Examiner is requesting a 1-hour fire rating and STC-50 between the two units. Our building code has typical assemblies for 2"x10" construction, and are therefore it is not acceptable to just slap a sample detail down and call it a day.
Any ideas how we can these ratings between the units?
Thanks!

The link has listed assemblies that will meet your requirements, which you can select
based on the construction type (wood frame, metal, etc.)
They also publish manuals that are really helpful.
