485-x

485-x is the successor to the 421-a lineage: property-tax exemptions for qualifying new multifamily construction, in exchange for affordability set-asides on the program's menus and, for larger projects, construction-wage requirements — the same land-for-outcomes bargain, renegotiated for its era. Terms, tiers, and conditions live in the current statute.

For analysis, the program's fingerprints will read like its predecessor's: benefits itemized on tax bills, affordability and regulation obligations during benefit terms, and vesting-date arithmetic determining which projects fall under which regime. The lineage's lesson transfers too — the program's conditions are era-specific, so the benefit's start date is the key to its terms.
