Getting the Submittal Right in San Gabriel
San Gabriel's Planning and Building divisions publish comprehensive lists and checklists of what a building permit submittal has to contain, covering single family, multifamily, accessory dwelling units and mixed use. That is genuinely helpful, and it also means there is no excuse for an incomplete package. We build the submittal to the checklist rather than waiting to be told what is missing.
There is a second reason to take the drawings seriously. San Gabriel, along with the other cities in the Los Angeles Basin, set up a committee to examine the code and made structural amendments because of proximity to the seismic faults. The local code is not the plain state code, and a set drawn to the generic version comes back.
The city sits in the San Gabriel Valley, bordered by San Marino to the north, Temple City and Rosemead to the east and Alhambra to the west. Of 13,461 housing units, about half of the occupied ones are rented, so much of the work is shared walkways, open stairs and stacked balconies.
Those buildings fail from the top down. Water passes the coating at an upper walkway, tracks along the ledger, and turns up as a soft tread or a stained ceiling below. The unit reporting the problem is rarely where the water got in.
Ground movement plays into it too. Joints that open and close season after season split a rigid coating exactly where it is doing the most work, which is why we detail wall junctions and stair connections to take movement rather than resist it.

Waterproofing in San Gabriel: Your Questions
Why do drawings get rejected here more than elsewhere?
Usually because the package is incomplete or drawn to the generic code. San Gabriel publishes detailed submittal checklists, and it adopted structural amendments because of the seismic faults nearby, so both have to be met.
My downstairs neighbor has a stain. Is it my balcony?
It might be, and it might be the walkway above you. Water tracks along framing before it appears, so the unit that reports the damage is rarely where the water entered. We trace it before quoting.
Do you work on apartment buildings in San Gabriel?
Regularly. About half of occupied units here are rented, so shared walkways, open stairs and stacked balconies are much of what we repair, sequenced so residents keep access.
