Why Does the Bronx Have the Most Rat Complaints in NYC?

The Bronx accounts for 40% of all rat-related 311 complaints in NYC since January 2024 — 8,457 complaints — despite having a smaller population than Brooklyn. The concentration reflects the borough's older building stock, higher density of large residential complexes, and persistent underfunding of building maintenance by some landlords.

Fordham leads all NYC neighborhoods at 2.8 rat complaints per building. Of 9,593 NYC buildings with rat complaints since 2024, only 353 received an HPD rodent violation — a 3.7% enforcement rate.
