Tenant Rights Law

My husband and I were recently advised that our landlord was not going to renew our lease all of a sudden after 4 years. We had an issue just three weeks earlier with our car being illegally towed from our parking spot . We contacted the apartments at crystal lake at 3801 Crystal Lake Drive Pompano Beach FL Who is owned by CJM properties in Canada and was advised that we were not going to be reimbursed for the towing fee of 150.00. I contacted CJM Properties via twitter and facebook and the next day we got the 150.00 back, I believe that the owners of these apartment complexes should be forced to provide a good reason for not renewing the lease if the tenant did not violate any terms of the lease. The complexes should have to provide written proof such as if the building is being torn down. Failure to enforce this petition allows the landlord to make up a reason or give no reason thus they can throw a tenant out for retaliation but it becomes difficult to prove. I believe that the tenant rights need to be improved. So with that being said the law needs to state that if the tenant did not violate any terms of the lease, written proof needs to be provided. Cjm Properties and the apartments and crystal lake retaliated against us and throughout a disabled person with cancer
