Brooklyn Open Data Exemptions - City Records Law

Technology and Data New York 3 Minutes Read ยท published February 02, 2026 Flag of New York

In Brooklyn, New York, agencies publish datasets to the city Open Data portal but may grant exemptions for sensitive records or statutory restrictions. This guide explains which municipal rules control exemption requests, which office reviews them, the practical steps to file a request, how to appeal a denial, and where to find official forms and contacts. It is written for Brooklyn residents, journalists, researchers, and business users who need to protect privacy, security, or proprietary information while complying with city open-data obligations.

How exemptions work

New York City implements an Open Data program requiring agencies to publish many datasets publicly; agencies may withhold or exempt datasets for specified legal or operational reasons. The Mayor's Office and the Department of Information Technology and Telecommunications administer city open-data policy and the portal itself, while statutory access and exemptions may also be governed by New York State law. For agency-specific exemption procedures, file requests through the NYC Open Data portal or the agency's records office.[1][2]

Exemptions are applied dataset-by-dataset and require an official review.

Penalties & Enforcement

The official Open Data materials and the implementing local law describe obligations for publishing data and for documenting exemptions, but specific monetary fines for failing to publish or for wrongful exemption are not specified on the cited city pages.[1] Statutory remedies under New York State Freedom of Information Law (FOIL) or other statutes may apply to access disputes; specific fines or daily penalties are not specified on the cited state page.[3]

  • Enforcer: Mayor's Office of Data Analytics (MODA) and DoITT for portal policy and agency compliance; individual agencies are accountable for dataset publication and exemption justifications.
  • Inspections/compliance: audits and published dataset change logs are used to verify compliance; procedural review occurs within the administering office.
  • Appeals: internal agency appeal routes and external legal remedies (administrative review or court) are available; precise appeal time limits are not specified on the cited pages.
  • Fines: specific monetary penalties or per-day fines are not specified on the cited city or state guidance pages.
  • Non-monetary sanctions: orders to publish, supervisory directives, and court orders to disclose records are possible enforcement outcomes.

Applications & Forms

City guidance directs requesters to the NYC Open Data portal and to agency records officers for exemption requests; a central named "exemption request" form is available through the portal or agency pages when provided, but the official pages do not publish a single universal form name or fee schedule for all exemption petitions.[2]

Check the dataset landing page on the NYC Open Data portal for the agency's exemption rationale and contact details.

Action steps to request an exemption

  • Identify the dataset and agency responsible on the NYC Open Data portal and review any posted exemption rationale.
  • Contact the agency records officer or the portal helpdesk to request an exemption or clarification; ask for the official exemption form if the agency uses one.
  • Document your request in writing and keep a copy of submission confirmations or portal receipts.
  • If denied, use the agency's internal appeal process and, if necessary, pursue administrative review or court remedies under applicable state or city law.
Preserve correspondence and timestamps for any appeal or legal challenge.

Common violations

  • Unjustified blanket exemptions for large datasets without documented legal basis.
  • Failure to publish required metadata, schema, or update logs.
  • Not following agency procedures for confidential or redacted fields.

FAQ

Who decides whether a dataset is exempt?
The city agency that owns the dataset makes the initial exemption determination, subject to portal policy and review by the administering offices.[1]
Can I appeal an exemption decision?
Yes; follow the agency's internal appeal process and consider legal remedies under FOIL or other statutes if administrative appeal is unsuccessful.[3]
Is there a fee to file an exemption request?
Fees for exemption requests are not specified on the cited city pages; contact the agency records office for fee information if any.[2]

How-To

  1. Locate the dataset on the NYC Open Data portal and note the owning agency and dataset ID.
  2. Use the portal contact tools or the agency records office to submit a written exemption request, attaching a justification and any supporting documents.
  3. Record the submission confirmation and await the agency response; if denied, request the agency's written rationale.
  4. File an internal appeal with the agency or pursue external review under applicable law if you believe the exemption is improper.

Key Takeaways
