Legal Question in Landlord & Tenant Law in Florida

Without seeing the lease agreement it is really impossible to answer this question. The statute should take precedence over a lease agreement in contravention of the statute. However, there can be negotiated items in a lease which do take precedence, like this provision, if they were specifically negotiated and agreed upon by the parties. the statute is not mandatory it gives landlords specific rights which they may enforce. No way to answer your question as simply as you believe. have you corrected the violation and notified the landlord of the correct?

Unless a lease provision waiver would violate public policy, it will be upheld. Up to judge to rule on this.

You will have to take your chances in court and allow the judge to rule on this. The fact that you researched this after you signed the lease may help in that you were unaware at the time of signing your understanding of the lease. ON the other hand, perhaps not. There is no easy answer here. My personal thought would be to remove the guest, info the landlord that you have done so and see where it goes from there. If the landlord does not wish to accept that you have complied, you may have to leave.
