(b) Not more than one exemption shall be allowed any individual or family unit or with respect to any residential unit. No exemption shall exceed the value of the real estate assessable to the owner or, in case of ownership through stock or membership in a corporation, the value of the proportion which the interest in the corporation bears to the assessed value of the property.
(c) By general law and subject to conditions specified therein, the Legislature may provide to renters, who are permanent residents, ad valorem tax relief on all ad valorem tax levies. Such ad valorem tax relief shall be in the form and amount established by general law.
(d) The legislature may, by general law, allow counties or municipalities, for the purpose of their respective tax levies and subject to the provisions of general law, to grant either or both of the following additional homestead tax exemptions:1
(2) An exemption equal to the assessed value of the property to a person who has the legal or equitable title to real estate with a just value less than two hundred and fifty thousand dollars, as determined in the first tax year that the owner applies and is eligible for the exemption, and who has maintained thereon the permanent residence of the owner for not less than twenty-five years, who has attained age sixty-five, and whose household income does not exceed the income limitation prescribed in paragraph (1).
(e)
(2) If a veteran who receives the discount described in paragraph (1) predeceases his or her spouse, and if, upon the death of the veteran, the surviving spouse holds the legal or beneficial title to the homestead property and permanently resides thereon, the discount carries over to the surviving spouse until he or she remarries or sells or otherwise disposes of the homestead property. If the surviving spouse sells or otherwise disposes of the property, a discount not to exceed the dollar amount granted from the most recent ad valorem tax roll may be transferred to the surviving spouse’s new homestead property, if used as his or her permanent residence and he or she has not remarried.
(3) This subsection is self-executing and does not require implementing legislation.
(2) The surviving spouse of a first responder who died in the line of duty.
(3) A first responder who is totally and permanently disabled as a result of an injury or injuries sustained in the line of duty. Causal connection between a disability and service in the line of duty shall not be presumed but must be determined as provided by general law. For purposes of this paragraph, the term “disability” does not include a chronic condition or chronic disease, unless the injury sustained in the line of duty was the sole cause of the chronic condition or chronic disease.
