(2) For the purpose of using Table 9.10.15.4. to determine the maximum permitted area of glazed openings in an irregularly-shaped or skewed exterior wall, the location of the exposing building face shall be taken as a vertical plane located so that there are no glazed openings between the vertical plane and the line to which the limiting distance is measured. (3) In determining the required cladding-sheathing assembly and fire-resistance rating for an irregularly-shaped or skewed exterior wall, the location of the exposing building face shall be taken as a vertical plane located so that no portion of the actual exposing building face is between the vertical plane and the line to which the limiting distance is measured. (4) The required limiting distance for an exposing building face is permitted to be measured to a point beyond the property line that is not the centre line of a street, lane or public thoroughfare if, (a) the owners of the properties on which the limiting distance is measured and the municipality enter into an agreement in which such owners agree that, (i) each owner covenants that, for the benefit of land owned by the other covenantors, the owner will not construct a building
on his or her property unless the limiting distance
for exposing building faces in respect of the proposed construction is measured in accordance with the agreement, (ii) the covenants contained in the agreement are intended to run with the lands, and the agreement shall be binding on the parties and their respective heirs, executors, administrators, successors and assigns, (iii) the agreement shall not be amended or deleted from title without the consent of the municipality, and (iv) they will comply with such other conditions as the municipality considers necessary, including indemnification of the municipality
by the other parties, and (b) the agreement referred to in Clause (a) is registered against the title of the properties to which it applies.
