C.R.S. § 38-33.3-210

(1) To exercise any development right reserved under section 38-33.3-205 (1)(h), the declarant shall prepare, execute, and record an amendment to the declaration and, in a condominium or planned community, comply with the provisions of section 38-33.3-209 . The declarant is the unit owner of any units thereby created. The amendment to the declaration must assign an identifying number to each new unit created and, except in the case of subdivision or conversion of units described in subsection (3) of this section, reallocate the allocated interests among all units. The amendment must describe any common elements and any limited common elements thereby created and, in the case of limited common elements, designate the unit to which each is allocated to the extent required by section 38-33.3-208 . (2) Additional development rights not previously reserved may be reserved within any real estate added to the common interest community if the amendment adding that real estate includes all matters required by section 38-33.3-205 or 38-33.3-206 , as the case may be, and, in a condominium or planned community, the plats and maps include all matters required by section 38-33.3-209 . This provision does not extend the time limit on the exercise of development rights imposed by the declaration pursuant to section 38-33.3-205 (1)(h). (3) Whenever a declarant exercises a development right to subdivide or convert a unit previously created into additional units, common elements, or both: (a) If the declarant converts the unit entirely to common elements, the amendment to the declaration must reallocate all the allocated interests of that unit among the other units as if that unit had been taken by eminent domain; and (b) If the declarant subdivides the unit into two or more units, whether or not any part of the unit is converted into common elements, the amendment to the declaration must reallocate all the allocated interests of the unit among the units created by the subdivision in any reasonable manner prescribed by the declarant. (4) If the declaration provides, pursuant to section 38-33.3-205 , that all or a portion of the real estate is subject to a right of withdrawal: (a) If all the real estate is subject to withdrawal, and the declaration does not describe separate portions of real estate subject to that right, none of the real estate may be withdrawn after a unit has been conveyed to a purchaser; and (b) If any portion of the real estate is subject to withdrawal, it may not be withdrawn after a unit in that portion has been conveyed to a purchaser. (5) If a declarant fails to exercise any development right within the time limit and in accordance with any conditions or fixed limitations described in the declaration pursuant to section 38-33.3-205 (1)(h), or records an instrument surrendering a development right, that development right shall lapse unless the association, upon the request of the declarant or the owner of the real estate subject to development right, agrees to an extension of the time period for exercise of the development right or a reinstatement of the development right subject to whatever terms, conditions, and limitations the association may impose on the subsequent exercise of the development right. The extension or renewal of the development right and any terms, conditions, and limitations shall be included in an amendment executed by the declarant or the owner of the real estate subject to development right and the association.
