Prop. Code Section 82.060
Exercise of Development Right
(a)To exercise a development right, the declarant must prepare, execute, and record an amendment to the declaration and record new plats and plans for that real property. 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 for subdivision or conversion of units described by Subsection (b), reallocate the allocated interest among all units. The amendment must describe any limited common elements created, designating the unit to which each is allocated.
(b)Development rights may be reserved within any real property added to the condominium if the amendment adding the real property includes the information required by Section 82.055 (Contents of Declaration for All Condominiums) or 82.056 (Leasehold Condominiums), as appropriate, and the plats and plans include the information required by Section 82.059 (Plats and Plans)(b). This provision does not extend the time limit on the exercise of development rights imposed by the declaration. Real property to be added is not part of a condominium or subject to a declaration until the declaration is amended to make the additional real property part of the condominium.
(c)Whenever a declarant exercises a development right to subdivide or convert a unit previously created into additional units, common elements, or both:
(1)if the declarant converts the unit entirely to common elements, the amendment to the declaration must reallocate all the allocated interests of the unit among the other units as if the unit had been taken by condemnation; and
(2)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.
(d)If the declaration provides that all or a portion of the real property is subject to the development right of withdrawal:
(1)if all the real property is subject to withdrawal, and the declaration does not describe separate portions of real property subject to that right, none of the real property may be withdrawn after a unit has been conveyed to a purchaser; and
(2)if a portion or portions are subject to withdrawal, no portion may be withdrawn after a unit in that portion has been conveyed to a purchaser.
