Commercial leases are controlled by Part I of the Landlord Tenant Act in Florida. It is found at Chapter 83 in the Florida Statutes. The terms of each lease are unique. For each particular situation an experienced business lawyer must review your lease to determine if you can be released from those obligations and what you can do.
With regard to Space One the lease expires soon by its own terms. Because you already paid the rent and did not give notice of intent to renew under the terms allowing for that you can continue to occupy the premises until the last day of the month. If you want to leave sooner, you can ask the landlord if it will agree to a pro-rated refund of the rent. If the landlord refuses then you can still vacate early, but may have to go to court to get a refund if the landlord takes possession and control for its own use. If the lease allows for fees and your business wins, then it can recover its fees. The winner gets their court costs like filing fees under Florida’s Landlord Tenant Act.
As to Space Two where you have no written lease your business is deemed a month-to-month tenant. Because it already paid the monthly rent it can continue to occupy the premises until the end of the month. As with Space One, if you tell the landlord you wants to leave then the landlord may be willing to refund part of the rent. But your business would only be entitled to a partial refund if the landlord takes possession for its own use before the end of the month. Unlike Space One because you have no written lease there is no automatic entitlement to attorneys fees in that lawsuit. But your business can still recover its costs if it prevails.
The Landlord Tenant Act in Florida and cases interpreting those statutes allow for a shorter response time in an eviction lawsuit. Instead of the normal twenty days, for the possession part of the eviction the time can be reduced to five days from the date of service. The tenant is also required to pay any rent due into the court registry or to move to determine that amount. Failure to do both will entitle the landlord to a default judgment for eviction.
The byproduct of an eviction is a writ of possession. The Writ commands the sheriff to place the landlord in possession of the premises. A claim for possession is separate from a claim for unpaid rent. The unpaid rent claim still adheres to the regular twenty day response time under the Rules of Civil Procedure.
If you are the landlord, the appropriate time to consult with counsel is when your tenant misses a monthly payment. You will want to assess whether to serve a proper notice and to know how much an eviction will cost and how long it will take. With that information you can make an informed business decision whether to negotiate a voluntary lease termination agreement that your business attorney should draft or to pursue the eviction in the courts.
