Each plat and plan must be clear and legible and contain a certification that the plat or plan contains all information required by this section.

(b) Each plat must show:

(1) The name and a survey or general schematic map of the entire common interest community;

(2) The location and dimensions of all real estate not subject to development rights or subject only to the development right to withdraw and the location and dimensions of all existing improvements within that real estate;

(3) A legally sufficient description of any real estate subject to development rights, labeled to identify the rights applicable to each parcel;

(4) The extent of any encroachments by or upon any portion of the common interest community;

(5) To the extent feasible, a legally sufficient description of all easements serving or burdening any portion of the common interest community;

(6) The location and dimensions of any vertical unit boundaries not shown or projected on plans recorded pursuant to subsection (d) and that unit's identifying number;

(7) The location with reference to an established datum of any horizontal unit boundaries not shown or projected on plans recorded pursuant to subsection (d) and that unit's identifying number;

(8) A legally sufficient description of any real estate in which the unit owners will own only an estate for years, labeled as "leasehold real estate";

(9) The distance between noncontiguous parcels of real estate comprising the common interest community;

(10) The location and dimensions of limited common elements, including porches, balconies and patios, other than parking spaces and the other limited common elements described in sections 2-102(2) and (4); and

(11) In the case of real estate not subject to development rights, all other matters customarily shown on land surveys.

(c) A plat may also show the intended location and dimensions of any contemplated improvement to be constructed anywhere within the common interest community. Any contemplated improvement shown must be labeled either "MUST BE BUILT" or "NEED NOT BE BUILT."

(d) To the extent not shown or projected on the plats, plans of the units must show or project:

(1) The location and dimensions of the vertical boundaries of each unit and that unit's identifying number;

(2) Any horizontal unit boundaries, with reference to an established datum and that unit's identifying number; and

(3) Any units in which the declarant has reserved the right to create additional units or common elements (section 2- 110(c)), identified appropriately.

(e) Unless the declaration provides otherwise, the horizontal boundaries of part of a unit located outside a building have the same elevation as the horizontal boundaries of the inside part and need not be depicted on the plats and plans.

(f) Upon exercising any development right, the declarant shall record either new plats and plans necessary to conform to the requirements of subsections (a), (b) and (d) or new certifications of plats and plans previously recorded if those plats and plans otherwise conform to the requirements of those subsections.

(g) Any certification of a plat or plan required by this section or section 2-101(b) must be made by an independent (registered) surveyor, architect or engineer.
