Brooklyn block parties require a Street Activity Permit from CECM (Street Activity Permit Office) with NYPD and DOT sign-off. Applications must be filed at least 30–90 days in advance and cost $25 for a single-day residential event.
A block party in Brooklyn requires a Street Activity Permit (SAPO) from the Community Affairs Unit / Street Activity Permit Office, which is part of the Citywide Event Coordination and Management (CECM) office. Applications open 120 days out and must be filed at least 30 days in advance (90 days recommended). Residential block parties cost $25; commercial events have higher fees. Requirements: community sign-off from at least 75% of block residents; NYPD precinct approval; DOT review of barricades and emergency vehicle access; DSNY notification for trash removal. Block parties typically run 9 AM–9 PM — music after 9 PM requires DEP noise variance. Amplified sound requires an NYPD Sound Device Permit under NYC Admin Code §10-108. Summer Saturdays are heavily booked; apply early.
Unpermitted block party: NYPD summons, equipment seizure, and civil fines up to $500. Noise Code violations after 9 PM: $350+. Illegal street barricades: DOT fines.
