If that's the case you need ot see if there is a provision in your lease that requires they follow all local codes and regulations in which case the city's requirement should be enough for you to pressure them to do it.  

Obviously there was no verbal agreement and I found out that the lady has a medical procedure done on Wednesday and probably wants to stiff arm me out of additional funds.

Have what I believe is a procedural question: chasing assets on a debtor in Las Vegas; he lied at Debtor's Examination because Writ of Garnishment came back from his bank "No Account"; started going after his house.

If you want to manage properties that you don't own, then you'd need a license.You'd benefit from connecting with other landlords in the area that you do business in so that you learn the local regulations and requirements. 

Keep in mind that rarely, and I mean rarely do rental housing regulations ever come down to the size of the owner's portfolio.  99% of regulations will correspond to the number of units in that property not the total number owned by the investor.

Due to stricter regulations in many newer condominium communities and it is less likely that your condo will become an illegal grow operation, drug manufacturing facility or party house4).

Don't want to deal w/ LA regulation when profit from Airbnb is starting to seem not worth it compared to longer term rental.
