a. Except as expressly provided in P.L.2008, c. 46 (C.52:27D-329.1 et al.) including subsection b. of this section, any provision of a local ordinance which imposes a fee for the development of affordable housing upon a developer of non-residential property, including any and all development fee ordinances adopted in accordance with any regulations of the Council on Affordable Housing, or any provision of an ordinance which imposes an obligation relating to the provision of housing affordable to low and moderate income households, or payment in-lieu of building as a condition of non-residential development, shall be void and of no effect.  A provision of an ordinance which imposes a development fee which is not prohibited by any provision of P.L.2008, c. 46 (C.52:27D-329.1 et al.) shall not be invalidated by this section.

b. No affordable housing obligation shall be imposed concerning a mixed use development that would result in an affordable housing obligation greater than that which would have been imposed if the residential portion of the mixed use development had been developed independently of the non-residential portion of the mixed use development.

c. Whenever the developer of a non-residential development regulated under P.L.1977, c. 110 (C.5:12-1 et seq.) 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, the non-residential development fee authorized pursuant to P.L.2008, c. 46 (C.52:27D-329.1 et al. ) shall be satisfied through the investment obligations made pursuant to P.L. 1977, c. 110 (C.5:12-1 et seq.).
