Prohibits development of affordable housing on contaminated land.

This bill (A5350) prohibits the development of affordable housing on land previously identified as contaminated, even after remediation or DEP certification of safety. It requires developers to conduct soil tests for land intended for affordable housing and submit results to local authorities; construction cannot begin on sites determined contaminated, except for DEP-certified safe sites. The bill applies to new development applications and municipal housing plans not yet approved, with penalties for violations including fines and loss of housing credit. It directly affects developers seeking to build affordable housing and municipalities managing housing obligations under state law.
