If it’s in the city of San Diego you can go look up whether there are any open inspection/citations on it. If it’s already been looked at towards condemnation – there will be a record of it and you can get that info. The City Engineers office is down on Aero in Kearny Mesa.
(We found out the furnace we had purchased/installed by Sears was never inspected when we went to find out something with the companion unit… The sears installer never called for the inspection, gave us the info to call ourselves, etc… and it flunked inspection because of a door clearance thing… they had to come fix it. Good thing we randomly found out.)
2nd point – all this earthquake, sky divers, etc … That’s what insurance is for. Just because you pay cash doesn’t mean you can’t purchase an insurance policy with an earthquake rider from the state. If you’re worried about this – buy insurance.
I like the plan you have, scaredy! But I’d do some work ahead of time to make sure the city doesn’t have outstanding citations.
