If your location really is Santa Barbara CA then all bets are off ... sorry but Californistan's rules tend to be different(onerous)
Not so, there are no rules regarding home inspection in the Peoples Socialist Republic of Kalifornia with the exception of one I have noted below and a pest report (commonly known as a termite inspection) that needs to be done to satisfy the lender that the house is not infested or rotting away. There may also be something for FHA or VA loans, but us has been a while since i have seen one of these.
To my fortune, I am in a seller's market regardless of the market conditions. If a house is on the market for more than 15 days, it just doesn't happen.
As a seller, I have always had an inspector come through and give me a report of what needs to be fixed. If it is a structure, mechanical, safety, or pest issue, I get it done before listing - I don't want to be on the last minutes of an escrow and have this hold it up. I don't bother with some stuff and put that in the disclosure - like "failing fence with a rear neighbor, the fence is on their property, etc... If it is cosmetic, good luck.
I had one buyer tell me they wouldn't move forward until I fixed or reduced the price on some pretty unreasonable stuff the inspection turned up - window shades, sprinkler system, oil spots on the driveway, the list went on. I politely responded that the purpose of the pre-buy is for you, the buyer, to get a better picture of the house's overall condition (foundation, roof, electrical, and plumbing), and it is upon you to manage these repairs. If this is unsatisfactory, we can cancel the escrow and move on.
We also often have sewer line inspections done if it's an older house or if trees could have roots affecting the sewer line. A hundred bucks or so to have a video bore scope done from the house to the street.
This is now mandatory where I live because of the use of Orangeburg pipe (
https://en.wikipedia.org/wiki/Orangeburg_pipe.) There have been a lot of failures creating some major issues.
Five of us got together after one of my neighbor's lines failed and had this replaced with PVC... It didn't need to be done as the inspection was ok, but it was just a matter of time. We made a volume deal with the plumber and saved, and now have peace of mind.
