Ask somebody who actually does those permanent foundations those questions. They probably have a standard procedure for tie-downs etc. I know the cost has gone up significantly. I've seen some cases where the perm fdn was installed but apparently the 433 was not recorded. Took a bit to track down the company that did the install, but that was determined and then 433 was recorded. If unknown, probably an engineer could be hired who is familiar with those things, to assess whether its compliant. Does FHA require the 433 in CA? Probably, but I would put that question back in the lap of the lender for them to determine what they will need to comply with FHA requirements. As an appraiser, I would state what I could confirm as fact, and not speculate further.
