Simply because there are so many rentals in the city and buildings that it would take an army of inspectors to enforce that.  

THEY WILL ENFORCE IT until the subdivision is finished.  

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

I am looking for forms and steps needed to just pass the deal off to a investor and be paid a referral fee and not be stung by non payment "enforced" legal form.

As @Michele Fischer said, it will probably be hard for me to enforce the 3X rent amount for income.

Make it clear that if they are late they will get a late fee and enforce it.

Thanks to the PATRIOT Act (which expanded various laws that had already been on the books at the time), among other things, when you go deposit that >$10k in cash at your bank or credit union, the cashier is going to have to fill out a little form and hand it to law enforcement, FYI.

@Jeff Angel check with your local Planning and Code Enforcement Departments.

They of course kept the info and eventually the relationship went downhill as I had to enforce some lease terms around some of their behavior which they pushed back against.
