Land Use and Zoning New York 3 Minutes Read ยท published February 20, 2026 Flag of New York

East New York, New York property owners and contractors must follow New York City historic preservation rules when altering designated buildings or properties in historic districts. This guide explains which municipal agencies enforce alteration review, how to apply for certificates or permits, typical compliance steps, and what to expect during inspections and appeals. It is written for owners, architects, contractors, and neighborhood advocates seeking clear action steps to start, complete, or challenge an alteration review.

Scope of Alteration Review

Alteration review in New York City applies to buildings and sites designated by the Landmarks Preservation Commission (LPC) and to properties in historic districts. For most exterior work and some interior work on designated interiors, owners must obtain LPC approval before seeking Department of Buildings (DOB) permits. Consult the LPC for whether a specific property or district is designated and for application categories.[1]

Check designation status before contracting work.

Typical Review Process

  • Prepare drawings and materials for LPC application.
  • File for a Certificate of Appropriateness or Certificate of No Effect with LPC when required.
  • After LPC action, obtain required DOB permits and inspections to begin work.
  • Follow any conditions in LPC approvals and complete DOB inspections to close permits.

Penalties & Enforcement

Enforcement of historic-preservation alteration rules involves the Landmarks Preservation Commission (administrative review and compliance directives) and the Department of Buildings (permit enforcement, stop-work orders, and civil penalties). When work is performed without required LPC approval or DOB permits, agencies may issue violations, stop-work orders, or require restoration.

  • Monetary fines: not specified on the cited page.[1]
  • Escalation: first, repeat, and continuing offence ranges are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, mandatory restoration, revoke or withhold permits, or referral for civil enforcement actions.
  • Enforcers and inspection pathways: Landmarks Preservation Commission for designation compliance and Department of Buildings for permits and inspections; complaints may be filed via LPC and DOB contact pages.[1]
  • Appeals and review: agency decisions can be challenged through administrative procedures and by seeking judicial review in state court (Article 78 petition) where applicable; specific time limits are not specified on the cited page.
  • Defences and discretion: documented emergencies, exigent safety repairs, or documented permits/variances may be considered; check LPC guidance for permitted emergency work protocols.
Agencies may require restoration to the original condition when work lacks approval.

Applications & Forms

The primary LPC application types include requests for Certificates of Appropriateness, Certificates of No Effect, and emergency work notifications. Specific form names and filing instructions are available from LPC application pages; DOB permits for construction and alteration follow after LPC approval when required.[1]

Action Steps

  • Confirm designation status with the LPC and review district rules.
  • Hire a licensed architect or preservation consultant to prepare LPC application drawings and narratives.
  • File with LPC for required certificate; after LPC decision, obtain DOB permits and schedule inspections.
  • If you receive a violation, follow the agency instructions to correct the work and pay any fines or request a hearing.
Begin review early to avoid stop-work orders and restoration mandates.
