(1) Property, real and personal, which is owned and used solely and exclusively for strictly charitable purposes and not for private gain or corporate profit shall be exempt from the levy and collection of property tax if such property is residential and the structure and the land upon which such structure is located are used as an integral part of a church, an eleemosynary hospital, an eleemosynary licensed health care facility, a school, or an institution whose property is otherwise exempt from taxation pursuant to the provisions of this part 1 and which is not leased or rented at any time to persons other than:

(a) Persons who are attending such school as students; or

(b) Persons who are actually receiving care or treatment from such hospital, licensed health care facility, or institution for physical or mental disabilities and who, in order to receive such care or treatment, are required to be domiciled within such hospital, licensed health care facility, or institution, or within affiliated residential units.

(2) Persons residing within residential units specified in paragraph (b) of subsection (1) of this section may submit to the administrator, on a form prescribed by the administrator, a certificate signed by a physician licensed to practice in the state of Colorado that the medical condition of such individual requires the individual to reside in such residential unit. If a person residing within such residential unit submits such signed certificate to the administrator pursuant to the provisions of this subsection (2), the portion of such residential property that is utilized by qualified occupants shall be deemed to be property used solely and exclusively for strictly charitable purposes and not for private gain or corporate profit and such portion, but only such portion, shall be exempt under the provisions of subsection (1) of this section. The determination as to what portion of such structure is so utilized shall be made by the administrator on the basis of the facts existing on the annual assessment date for such property, and the administrator shall have the authority to determine a ratio which reflects the value of the nonexempt portion of such structure in relation to the total value of the whole structure and the land upon which such structure is located and which is identical to the ratio of the number of residential units occupied by nonqualified occupants to the total number of occupied residential units in such structure.

(2.5) No requirement shall be imposed that use of property which is otherwise exempt pursuant to the provisions of this section shall benefit the people of Colorado in order to qualify for said exemption.

(3) Any exemption claimed pursuant to the provisions of this section shall comply with the provisions of section 39-2-117.
