What is a lease amendment?

A lease amendment is a short writing that changes specific terms of an existing lease — rent, end date, occupants, pets, or parking — without rewriting the whole contract.

Do both parties have to sign an amendment in Florida?

Yes. An unsigned draft does not change the lease. Keep the original lease and attach signed amendments so the full agreement is clear later.

Deposit rule of thumb

Florida does not cap the size of a residential security deposit. If the landlord makes no claim, the unused deposit is generally due within 15 days after the tenant vacates. If the landlord is keeping some or all of it, written notice of the claim is generally due within 30 days. The lease or a notice should say how and where the deposit is held.

Fla. Stat. § 83.49

The landlord may enter at reasonable times to inspect, repair, or show the unit. Twelve hours’ notice is presumed reasonable. Emergency entry does not require notice (Fla. Stat. § 83.53).

If rent is paid monthly, either party generally may end a month-to-month tenancy with 15 days’ written notice before the end of the monthly period (Fla. Stat. § 83.57).
