However, the Legislature may provide that, under appropriate circumstances and pursuant to definitions and procedures established by the Legislature, any person over the age of 55 years who resides in property that is eligible for the homeowner’s exemption under subdivision (k) of Section 3 of Article XIII and any implementing legislation may transfer the base year value of the property entitled to exemption, with the adjustments authorized by subdivision (b), to any replacement dwelling of equal or lesser value located within the same county and purchased or newly constructed by that person as his or her principal residence within two years of the sale of the original property. For purposes of this section, “any person over the age of 55 years” includes a married couple one member of which is over the age of 55 years. For purposes of this section, “replacement dwelling” means a building, structure, or other shelter constituting a place of abode, whether real property or personal property, and any land on which it may be situated. For purposes of this section, a two-dwelling unit shall be considered as two separate single-family dwellings. This paragraph shall apply to any replacement dwelling that was purchased or newly constructed on or after November 5, 1986.
In addition, the Legislature may authorize each county board of supervisors, after consultation with the local affected agencies within the county’s boundaries, to adopt an ordinance making the provisions of this subdivision relating to transfer of base year value also applicable to situations in which the replacement dwellings are located in that county and the original properties are located in another county within this State. For purposes of this paragraph, “local affected agency” means any city, special district, school district, or community college district that receives an annual property tax revenue allocation. This paragraph applies to any replacement dwelling that was purchased or newly constructed on or after the date the county adopted the provisions of this subdivision relating to transfer of base year value, but does not apply to any replacement dwelling that was purchased or newly constructed before November 9, 1988.
The Legislature may extend the provisions of this subdivision relating to the transfer of base year values from original properties to replacement dwellings of homeowners over the age of 55 years to severely disabled homeowners, but only with respect to those replacement dwellings purchased or newly constructed on or after the effective date of this paragraph.
(b) The full cash value base may reflect from year to year the inflationary rate not to exceed 2 percent for any given year or reduction as shown in the consumer price index or comparable data for the area under taxing jurisdiction, or may be reduced to reflect substantial damage, destruction, or other factors causing a decline in value.
(c) For purposes of subdivision (a), the Legislature may provide that the term “newly constructed” does not include any of the following:
(2) The construction or installation of any fire sprinkler system, other fire extinguishing system, fire detection system, or fire-related egress improvement, as defined by the Legislature, that is constructed or installed after the effective date of this paragraph.
(3) The construction, installation, or modification on or after the effective date of this paragraph of any portion or structural component of a single- or multiple-family dwelling that is eligible for the homeowner’s exemption if the construction, installation, or modification is for the purpose of making the dwelling more accessible to a severely disabled person.
(4) The construction, installation, removal, or modification on or after the effective date of this paragraph of any portion or structural component of an existing building or structure if the construction, installation, removal, or modification is for the purpose of making the building more accessible to, or more usable by, a disabled person.
(5) The construction or addition, completed on or after January 1, 2019, of a rain water capture system, as defined by the Legislature.

(3) In addition to the transfer of base year value of property within the same county that is permitted by paragraph (1), the Legislature may authorize each county board of supervisors to adopt, after consultation with affected local agencies within the county, an ordinance allowing the transfer of the base year value of property that is located within another county in the State and is substantially damaged or destroyed by a disaster, as declared by the Governor, to comparable replacement property of equal or lesser value that is located within the adopting county and is acquired or newly constructed within three years of the substantial damage or destruction of the original property as a replacement for that property. The scope and amount of the benefit provided to a property owner by the transfer of base year value of property pursuant to this paragraph shall not exceed the scope and amount of the benefit provided to a property owner by the transfer of base year value of property pursuant to subdivision (a). For purposes of this paragraph, “affected local agency” means any city, special district, school district, or community college district that receives an annual allocation of ad valorem property tax revenues. This paragraph applies to any comparable replacement property that is acquired or newly constructed as a replacement for property substantially damaged or destroyed by a disaster, as declared by the Governor, occurring on or after October 20, 1991, and to the determination of base year values for the 1991–92 fiscal year and fiscal years thereafter.
(2) Replacement property is comparable to the property substantially damaged or destroyed if it is similar in size, utility, and function to the property that it replaces, and if the fair market value of the acquired property is comparable to the fair market value of the replaced property prior to the disaster.
(2) Transfers to a spouse that take effect upon the death of a spouse.
(3) Transfers to a spouse or former spouse in connection with a property settlement agreement or decree of dissolution of a marriage or legal separation.

The full cash value of any real property, other than a principal residence, that was transferred to the grandchild or grandchildren pursuant to a purchase or transfer that was excludable pursuant to paragraph (1), and the full cash value of a principal residence that fails to qualify for exclusion as a result of the preceding sentence, shall be included in applying, for purposes of subparagraph (A), the one-million-dollar ($1,000,000) full cash value limit specified in paragraph (1).
