These rules are based on Fannie Mae underwriting standards, so any lender offering these loans must comply.

Still of course, we want to fully comply with the law for access.Until we can get an electrician on site to relocate this panel upstairs in their unit, is there a keypad access lock that comes to mind that issues 1x use codes and provides a notification to me when it is used?

You can comply or find a new insurance co.  

- The format of this does not include materials....should I have a consistent format that the GCs need to comply with?

I know next to nothing about tenancy law, and even less about Canadian tenancy laws, but it seems highly unlikely that they can evict current tenants who don't comply since those folks have a signed contract.

They will examine the zoning code and advise as to how big your structure could be to comply with all relevant ordinances.

@Julia PreciadoUnless California Law requires a move out inspection in order for the tenant to conduct repairs, I would not comply.  

A party who enters into a rental agreement on behalf of the landlord and fails to comply with this section is an agent of the landlord for purposes of: (a) Service of process and receiving notices and demands; and (b) Performing the obligations of the landlord under law and under the rental agreement. 4.  

While there sometimes isn't much strict enforcement of the rules by the city (like imposing fines, or forcing you to comply), I'm not surprised that a lender wouldn't be willing to count the income from a rental unit that isn't technically allowed. 

So long as it is placed with a “regulated financial institution” in either an interest or non-interest bearing account, I believe the landlord would have complied with the statute.
