c. Whenever non-residential development is situated on real property that has been previously developed with a building, structure, or other improvement, the non-residential development fee shall be equal to two and a half (2.5) percent of the equalized assessed value of the land and improvements on the property where the non-residential development is situated at the time the final certificate of occupancy is issued, less the equalized assessed value of the land and improvements on the property where the non-residential development is situated, as determined by the tax assessor of the municipality at the time the developer or owner, including any previous owners, first sought approval for a construction permit, including, but not limited to, demolition permits, pursuant to the State Uniform Construction Code, or approval under the "Municipal Land Use Law," P.L. 1975, c.291 (C.40:55D-1 et seq.). If the calculation required under this section results in a negative number, the non-residential development fee shall be zero. Whenever the developer of a non-residential development has made or committed itself to make a financial or other contribution relating to the provision of housing affordable to low and moderate income households prior to the enactment of P.L. 2008, c. 46(C.52:27D-329.1 et al.), the non-residential development fee shall be reduced by the amount of the financial contribution and the fair market value of any other contribution made by or committed to be made by the developer. For purposes of this section, a developer is considered to have made or committed itself to make a financial or other contribution, if and only if:
(1) the contribution has been transferred, including but not limited to when the funds have already been received by the municipality;(2) the developer has obligated itself to make a contribution as set forth in a written agreement with the municipality, such as a developer's agreement; or (3) the developer's obligation to make a contribution is set forth as a condition in a land use approval issued by a municipal land use agency pursuant to the "Municipal Land Use Law," P.L. 1975, c.291 (C.40:55D-1 et seq.).
