Notwithstanding the limitation set forth in subdivision (a) of Section 17021.3, the costs of a modernization or renovation project funded under this chapter may exceed 25 percent of the replacement cost of an existing structure where the costs in excess of that amount are funded by the district exclusively from sources other than any state program administered by the board. For each project, the total costs of the modernization or renovation project, as supplemented pursuant to this section, may not exceed 50 percent of the replacement cost of the existing structure except to the extent of those costs funded by the district, from sources other than any state program administered by the board, that are expended to conform that structure to current building standards, in which event the total costs of the project may not exceed 75 percent of the replacement cost of the structure.
