Environmental Protection New York 3 Minutes Read · published February 02, 2026 Flag of New York

Brooklyn, New York buildings can pose collision risks for migratory and resident birds. This guide explains the current municipal approach to bird-safe design for buildings in Brooklyn, identifies the enforcing offices, outlines likely enforcement outcomes, and provides practical steps property owners, designers, and managers should take to reduce collisions and demonstrate compliance.

Penalties & Enforcement

There is no separate Brooklyn borough law; enforcement and permitting for building façades and construction occur at the City of New York level. Specific monetary fines or statutory bird-design fines are not specified on the cited page[1]. For wildlife complaints and hazardous conditions, residents should use NYC 311 for reporting and referral[2].

  • Monetary fines: not specified on the cited page[1].
  • Escalation: first, repeat, or continuing offences and per-day penalties are not specified on the cited page[1].
  • Non-monetary sanctions: orders to alter façades, stop-work orders, compliance notices, and court actions are tools used by enforcement agencies; exact remedies for bird-collision issues are not specified on the cited page[1].
  • Enforcer and complaint pathway: primary enforcement and permit authority is the NYC Department of Buildings; public reporting and urgent hazard referrals use NYC 311[1][2].
  • Appeals/review: administrative reviews or hearings are handled through the city hearing processes; specific time limits for appeals related to bird-safe directives are not specified on the cited page[1].
If you observe repeated collisions at a property, document time, date, and photos before reporting to 311.

Applications & Forms

  • DOB permits and applications for façade work or alteration: use the DOB permit application process; specific "bird-safe" permit forms are not published on the cited page[1].
  • Fees: permit fees for façade or glazing work are set by DOB schedule; bird-specific fee amounts are not specified on the cited page[1].
  • How to submit: follow DOB online filing and 311 reporting procedures found on official city pages[1][2].

Design and Compliance Steps

Design and property-management actions reduce collision risk and demonstrate due diligence to city inspectors and reviewers. Typical steps include selecting bird-friendly glass or treatments, minimizing large uninterrupted panes, using visible patterns on glazing, timing exterior lighting, and documenting design decisions in permit submissions.

  • Design changes: specify patterned frit, external screens, or other mitigation during façade work.
  • Recordkeeping: keep specifications, product data, and installation photos for inspections.
  • Construction scheduling: note migration seasons and avoid peak migration periods when feasible.
Document mitigation and maintenance to support compliance reviews and complaints resolution.
