I have an existing building probably mid 1970's.
Problem is existing property line walls with 0 distance, non-rated (I think) and no parapets.
We are not touching the walls except on the inside we are stripping the inside layer of drywall, adding 1/2" plywood and 5/8" type 'x' gyp. bd.
It already has 7/8" stucco on outside, so we in effect 1-houring the wall.
The property line walls do not have the required 30" parapet, and adding the parapet would require too much work and total re-design work.
The alternative is 705.11 exception 4. I'm don't think the existing roof can handle the extra weight of two layers of drywall.
Section 3403.1 of the california building code appears to limit the requirements for existing buildings stating 'Alterations..........to ensure that no less conforming than prior to the addition"
Actually we are upgrading to 1-hr. and fire blocking the wall, so it is more conforming than the existing.
We want to leave it at that and not overstress the existing roof with drywall or alter the building design with a new parapet.
Want to make sure though that I'm interpreting this right.
Thanks much
