I have done flooring, tile patios, hot water heaters, masonry work, molding and concrete work on personal projects so I know some about cost of repairs and timelines of projects (Always over on both from my experience).

Now I have a new property here in Florida and it is a concrete block house with some big windows in the living room. 

Between these two walls is essentially a walkable concrete path to a crash gate that is part of that community wall.The problem here is that vehicles that can't make a full turn on the cul-de-sac tend to stop in front of the homeowner's driveway and then back up.

Is there something more concrete?

Are you compliant?

But after considering these other factors (bathrooms, hallways,  ADA compliance), I am concerned that I'm unable to provide what they are asking. 

There is an additional cost to pay for them to inspect the crawl space which saved me a lot of money when we saw the effects of the blowout underneath the newly floored bathroom and how they supported the floor with 2x4's directly into the ground with no concrete footings or anything.The owner also teaches  at a local community college on how to inspect the different systems in a house. 

Department of Justice's publication Frequently Asked Questions about Service Animals and the ADA which are relevant to your situation:Q: Are service-animals-in-training considered service animals under the ADA?

It’s hard to give more concrete advice that still applies to any first property.

The contractor should have access to roofers, framers, concrete, pool, plumbers, electrical, tile, sheetrock, kitchen & bathroom installers, painters etc and should pull the permits.
