There is an incentive improvement program, as provided in this section. Subject to appropriations by the Ordinance of Estimates, the Commission for Historical and Architectural Preservation may contract with the owner or lessee of a structure that is located within a Historical and Architectural Preservation District or a Historical Conservation District or included on the Landmark List to reimburse that owner or lessee of up to 20% of the cost incurred by her or him in the reconstruction, alteration, removal, repair, or painting of an architectural feature in a manner that furthers the purposes of <cite data-path="|6">this article</cite>. In no event may the Commission authorize any reimbursement under the program until all of the work to be done and the estimated cost of that work has been approved by the Commission. In all cases, the Commission retains full discretion to determine the scope, nature, and cost of all work subject to reimbursement under the program.
