(3) An individual who owns and occupies a dwelling unit in a common interest community, as defined in section 38-33.3-103 (8), C.R.S., as his or her primary residence, or who owns residential real property consisting of multiple-dwelling units and occupies one of the dwelling units as his or her primary residence, shall be allowed an exemption only with respect to the dwelling unit that the individual occupies as his or her primary residence.

(I) The owner-occupier would have qualified for the exemption with respect to other residential real property that the owner-occupier owned and occupied as his or her primary residence before moving to the residential real property for which an exemption is claimed but for the fact that the other property was condemned by a governmental entity through an eminent domain proceeding; or

(I.5) For property tax years commencing on or after January 1, 2015, the owner-occupier would have qualified for the exemption with respect to other residential real property that the owner-occupier owned and occupied as his or her primary residence before moving to the residential real property for which an exemption is claimed but for the fact that a natural disaster destroyed the former primary residence or otherwise rendered it uninhabitable; and

(II) The owner-occupier has not owned and occupied residential property as his or her primary residence other than the residential real property for which an exemption is claimed since the condemnation occurred.

(b) An owner-occupier who claims an exemption with respect to residential real property that he or she has not actually owned and occupied as his or her primary residence for the ten years preceding the assessment date as permitted by paragraph (a) of this subsection (6) shall provide to the assessor with whom the owner-occupier files the exemption application any information that the assessor may reasonably require to verify that the owner-occupier is entitled to an exemption.
