Confused about zoning restrictions provided by Redfin

[David Lou]

I'm searching for some multi family properties to invest in the Ft Lauderdale, FL area. My plan was initially to use the properties as an STR to be able to execute the STR loophole strategy. However, looking at all the multi family listings and the zoning information on Redfin shows that these explicitly do not allow Short term rentals. However, I'm confused because I've seen multiple examples (5?) where I found the exact unit listed on AirBnB. How can the zoning state that STR is not allowed, yet these small multi family units are all on AirBnB? Am I missing something or not understanding something here? I want to make sure that I don't buy a property that I cannot legally operate as an STR.
