Statutory Summary: Fla. Stat. § 83.57

Florida Residential Landlord Tenant Act requires 30 days notice for month-to-month leases. Daily proration reflects actual month length.

Florida Residential Landlord and Tenant Act (Fla. Stat. § 83.57)

Under Florida law, periodic tenancies require strict compliance with statutory notice timelines:

  • Month-to-Month Notice: Either party may terminate a month-to-month rental by delivering written notice at least 30 days prior to the conclusion of the monthly period (updated by SB 636).
  • Deposit Return Timeline (Fla. Stat. § 83.49): If the landlord does not intend to impose a claim on the deposit, it must be returned within 15 days. If making deductions, the landlord has 30 days to provide written itemized notice via certified mail.

Frequently Asked Questions: Florida Rent Proration

If you have a fixed-term 12-month lease that ends on the last day of the month and you choose to leave early without landlord consent, you are generally liable for full rent until a new tenant moves in or the term expires. However, if you are on a month-to-month tenancy and provide a lawful 30-day notice under Fla. Stat. § 83.57, you are only legally liable for rent through the expiration date of your notice.

Under Florida statutes, landlords must return your security deposit within 15-30 Days following key surrender, along with an itemized accounting of any deductions made for unpaid rent or lawful repairs beyond normal wear and tear.
