(1) To exercise any development right reserved under RCW 64.90.225(1)(g), the declarant must prepare, execute, and record any amendments to the declaration and map in accordance with the requirements of RCW 64.90.245 and 64.90.285(3). The declarant is the unit owner of any units created. The amendment to the declaration must assign an identifying number to each new unit created and, except in the case of subdivision, combination, 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 created and, in the case of limited common elements, designate the unit to which each is allocated to the extent required under RCW 64.90.240. The amendments are effective upon recording.

(2) Development rights may be reserved within any real estate added to the common interest community if the amendment to the declaration adding that real estate includes all matters required under RCW 64.90.225 and 64.90.230 and the amendment to the map includes all matters required under RCW 64.90.245. This subsection does not extend the time limit on the exercise of development rights imposed by the declaration pursuant to RCW 64.90.225(1)(h).

(3) When a declarant exercises a development right to subdivide, combine, or convert a unit previously created into additional units or common elements, or both:

(a) If the declarant converts the unit entirely into 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 condemnation under RCW 64.90.030; or

(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 RCW 64.90.225(1)(h), 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 or map or amendment to the declaration or map does not describe separate portions of real estate subject to that right, none of the real estate may be withdrawn if a unit in that real estate has been conveyed to a purchaser; or

(b) If any portion of the real estate is subject to withdrawal as described in the declaration or map or amendment to the declaration or map, none of that portion of the real estate may be withdrawn if a unit in that portion has been conveyed to a purchaser.

(5) If the declarant combines two or more units into a lesser number of units, whether or not any part of a unit is converted into common elements or common elements are converted units, the amendment to the declaration must reallocate all of the allocated interests of the units being combined into the unit or units created by the combination in any reasonable manner prescribed by the declarant.

(6) A unit conveyed to a purchaser may not be withdrawn pursuant to subsection (4)(a) or (b) of this section without the consent of the unit owner of that unit and the holder of a security interest in the unit.
