Jersey City Tax Abatement/market rate housing fee question

[Steven O'Leary]

I recently purchased a 3 family in the Journal Square.  My understanding was that there was a tax abatement since it was new construction.  I found out upon going to the tax collectors office that the application for the 5 year tax abatement was filed by the builder, but the Market Rate Housing fee was not paid.  JC requires $1500 per unit is given to the affordable housing trust fund.

My question is who is responsible for the $4500, the buyer or the builder/developer?  Of course the developer feels it is my responsibility and I feel it is his.   Anyone have insight on this?
