Florida's Save Our Homes rule caps yearly increases in the assessed value of a homestead. A "change of ownership" can reset the assessment to market value, so homeowners often ask whether adding a name triggers that reset.
Under section 193.155, several transfers are not treated as a change of ownership:
Adding or removing a spouse, including transfers after a divorce or to a surviving spouse.
Deeds where the owner is both the grantor and a grantee and simply adds another person, as long as the owner keeps the homestead exemption.
Deeds that only correct an error.
There is a catch. If the person added later applies for a homestead exemption on the property, the law treats that as a change of ownership.
A new owner who qualifies for and wants a homestead exemption applies to the county property appraiser by March 1 of the tax year (section 196.011(1)). When there is a change of ownership, the property is reassessed at just value as of January 1 of the following year (section 193.155(3)(a)).
Adding a child or partner can still have other effects, such as a gift tax filing, doc stamps on any mortgage balance, and exposure to the new owner's creditors. A lady bird deed is one way to name family members without giving them ownership now. See how a lady bird deed affects homestead, or read how to add someone to a deed.
