Historic Alteration Certificate - Brooklyn City Law

Land Use and Zoning New York 4 Minutes Read ยท published February 02, 2026 Flag of New York

In Brooklyn, New York, contractors working on landmarked buildings or properties within historic districts must secure approval from the New York City Landmarks Preservation Commission before altering protected features. This article explains the municipal approval process, the agencies involved, typical timelines, enforcement consequences, and practical steps for submitting an application and coordinating building permits.

Overview

Work affecting designated landmarks or properties in historic districts typically requires a certificate from the Landmarks Preservation Commission (LPC). The LPC issues approvals such as Certificates of Appropriateness or Certificates of No Effect depending on the scope of work. Contractors should confirm LPC requirements early because the LPC review is separate from the Department of Buildings permit process and may be required before DOB issues a permit. For application steps and LPC procedures, see the LPC application pages LPC Applications[1].

Obtain LPC approval before filing for DOB permits whenever work affects exterior or significant interior features.

Penalties & Enforcement

Enforcement is led by the New York City Landmarks Preservation Commission in coordination with the Department of Buildings. Specific civil penalties and enforcement actions for work without required LPC approval are set out by the enforcing agencies; if exact fines or penalty schedules are not listed on the cited LPC or DOB pages, this article notes that they are not specified on the cited page and directs readers to official contact pages for case-specific information.

  • Monetary fines: not specified on the cited page; contact LPC or DOB for current penalty figures and schedules.[1]
  • Escalation: first offence and repeat/continuing offence ranges are not specified on the cited LPC pages; enforcement may increase for continuing violations.[1]
  • Non-monetary sanctions: stop-work orders, orders to restore altered features, revocation of permits, and court injunctions are used by LPC and DOB.
  • Enforcer and inspection: LPC enforces landmark rules and inspects sites; DOB may issue permits and inspect for code compliance. Report violations via LPC contact channels or NYC311.
  • Appeals and review: appeal procedures vary by agency; time limits for administrative review or appeals are not specified on the cited pages and should be confirmed with LPC or DOB directly.[1]
Timely appeals and compliance responses are critical to avoid escalated enforcement.

Applications & Forms

The LPC publishes application types and form downloads for Certificates of Appropriateness, Certificates of No Effect, and related filings. Where forms list fees or submission requirements, follow the LPC instructions and file the documents with required drawings and photographs. See LPC forms and filing instructions on the official forms page LPC Forms[2].

  • Common form names: Certificate of Appropriateness application, Certificate of No Effect application; specific form numbers or fee amounts are not specified on the cited page and should be confirmed on the LPC forms page.[2]
  • Submission method: LPC accepts in-person or electronic submissions per its current instructions on the forms page.[2]
  • Fees: check the LPC forms page for current application fees; if a fee is not listed there then it is not specified on the cited page.[2]

Process for Contractors

Contractors should coordinate LPC approval and Department of Buildings permits: prepare detailed drawings, photographs, and material specifications for LPC review; obtain LPC approval document before submitting DOB permit applications that depend on the LPC decision; and follow any LPC conditions required in the approval.

Coordinate document sets so LPC and DOB reviewers see consistent scope and materials.

How-To

  1. Determine if the property is a landmark or in a historic district by checking LPC designations and property status.
  2. Prepare application materials: drawings, elevations, photographs, and material samples consistent with LPC guidance.
  3. Submit the appropriate LPC application (Certificate of Appropriateness or Certificate of No Effect) following the LPC forms instructions.[2]
  4. Wait for LPC review and decision; respond to any requests for additional information promptly.
  5. If LPC approval is required, obtain LPC approval documentation and include it with the DOB permit application; coordinate inspections as needed with DOB and LPC.[3]
  6. Pay fees and follow conditions of approval; monitor compliance and complete required inspections to close permits.
