Riverdale.

Three structural factors: (1) housing stock vintage skews mid-century elevator buildings rather than pre-war walk-ups, so fewer building-systems issues from age; (2) the single-family stock is owner-occupied with no landlord-tenant complaint dynamic; (3) the apartment stock is overwhelmingly co-op with professional management and active reserve funds. The result is genuinely lower counts.

Most Riverdale co-ops (along Henry Hudson Parkway, Palisade, and the Independence Avenue corridor) average very low open-violation counts. A handful carry layered façade or elevator filings tied to Local Law 11 or modernization cycles. The audit shows the specific building's record; the gap between best and worst Riverdale co-op is small compared to other Bronx neighborhoods.

Some pre-1974 6+ unit Riverdale rental buildings are rent-stabilized through standard rules, but the overwhelming majority of Riverdale's apartment stock is co-op rather than rental, removing those buildings from stabilization. The audit's DHCR check shows the specific building's status; rental vs co-op makes a big difference here.

Yes — any BBL with a registered Certificate of Occupancy can be audited. For Riverdale single-family homes the audit pulls DOB permit history, any open violations (usually few), FEMA flood zone, ACRIS sales history, and neighborhood signals. Single-family Riverdale homes typically have very few open violations.

Riverdale's open-violation rate is dramatically lower than the rest of the Bronx — closer to Bay Ridge or Forest Hills levels than to Mott Haven or Fordham. The Henry Hudson Parkway is one of NYC's sharpest compliance gradients, with elevated mid-century co-ops on one side and older central-Bronx walk-up stock on the other. The audit shows BBL-specific data.
