Please shoot me an email Sandy, and I'll connect you with them.  

As it can get slick if sand is not added for slip resistance to the paint and is now a maintenance issue. 

Approximately 95% of the crawl space was not accessible due to the height between the bottom of the floor joists and the soil.

Basically they are saying that the soil beneath the garage is not stable and could keep sinking in the future, which would cause more structural damage to the garage.If I were you, I would first do a soil sample to see if the soil is still settling and if it is, then you will have to do what they recommend and that is a pier system.

@Sandy UhlmannHi Sandy! 

Subterranean parking is expensive, and it's much more expensive to build 3rd or 4th floors, it means gigantic footings, soils analysis, structural design and etc.

Hence, the low acquisition price.Construction defects law:  Hardly any condos have been built for some years now because of the problems with foundations and shifting soils meant builders were liable for bad engineering.  

What are the things I should be aware of - permits, soil testingI have no building experience and planning on hiring a Contractor to build - I plan to be more hands on after I have one successfully completed projectWhat are the pros and cons of having a property on a hill (West Hills area)Is it wise to take my contractor to inspect the land before I put down an offer - it is a .75 acre lotHow much would 1 SQft cost in Los Angeles area?

I have been helping a friend with a flip in Sandy the last few months and am almost all finished so the timing is good!

I forgot all about the soil issues there.
