(1) Nothing in this Chapter shall effect the powers of the Municipal Commissioner or any other authority or the rights or liabilities of any person (including the owner or any occupier) to carry out any repairs to any building, or to execute any works thereon or to take any other action in respect of such building authorised under section 257, 354, 377A, 381, 489 or 499 or any other provisions of the Corporation Act, or under section 10D or 10E or any other provisions of the Rent Act, or under the provisions of any other law for the time being in force, in so far as the said repairs, works or action does not require any structural repairs; and in so far as they do require structural repairs, until such repairs are undertaken by the Board :
Provided that, if any occupier of a building seeks the approval of the Municipal Commissioner under section 499 of the Corporation Act, for carrying out structural repairs in respect of any such building, such approval may be given by the Municipal Commissioner only after consultation with the Board, but the occupier shall not be entitled to recover from the owner under the said section 499 the expenses incurred by him on any such structural repairs :
Provided further that, during the period this Chapter is in force, the provisions of section 10D and 10E of the Rent Act, shall not apply to any building, in so far as they relate to buildings undertaken or proposal to be undertaken by the Board for structural repairs.
(2) If, while carrying out any repairs, or executing any works or taking any action referred to in sub-section (1), it becomes necessary for the Municipal Commissioner or any other authority or any person to carry out structural repairs also, and the Municipal Commissioner or such authority or persons desires that the cost of the structural repairs should be paid by the Board, the Municipal Commissioner or such authority or person, as the case may be, shall obtain the previous sanction of the Board for such repairs. The Board may give such sanction on such terms and conditions as it may deem fit to impose, having regard to the priority, if any, assigned to the building under sub-section (2) of section 88 and availability of resources; or may not agree to give such sanction.
(3) Where sanction is given under sub-section (2), it shall be lawful for the Board to pay the cost of the structural repairs actually carried out in lumpsum or by instalments or according to the progress of the work from time to time as it may deem fit.
(4) When the Board pays the cost of the structural repairs in full, or when a period of three months elapses after the Board has paid not less than seventy-five per cent. of such cost, whichever is earlier, the building shall be deemed to be structurally repaired by the Board under this Chapter.
