This issue is in Florida.
Here are the quick facts. A guy rents a storage unit and stores expesnive equipment inside. The renal agreement is for a one year term. There have been multiple break-ins to his unit and it appears that local theives know of the type of equipment stored inside.
Questions -
1. - Is this type of criminal activity a breach of the covenant of quiet enjoyment of the leasehold?
2. - If quiet enjoyment is warranted, does the breach require any fault on the part of the landlord? Or does the criminal activity automatically breach the warranty just by happening?
3. - Are there any other ways the guy can get out of his lease?
Thank you for any help/responses!
