I'd be willing to help you out as much as I can on being compliant, and focused on the things that will get you to the goal. 

I would like to know whether are all restaurants required to have ADA compliant restrooms?

All 1031 compliant. 

Because you can report non-passive losses on Sch E to be compliant with 469, but you cannot block SE tax on Sch C to be compliant with 1402.

I don't see the problem to be compliant with TILA HPML Escrow Rule, do you?

If I were buying a property that was not permitted, I would ask the seller to come off the price by half for all the possible repairs needed to bring the property compliant. 

The kitchen is also not GFCI compliant.

You can personally try to contact code enforcement and plead your case that your crooked property manager screwed you and that you are going to get compliant. 

What are some of the negative impacts you are noticing and what are you doing to stay compliant?

The PM maintains a list of vendors who they vet and must ensure the vendors are compliant with their operating standards such as having a Certificate of Insurance naming the PM as an additional insured, receive invoices from said vendors, pay vendors, checks vendor work (in some cases) and ensure the invoice is appropriately accounted for in the asset/owners account.
