New York City, New York property owners and contractors must follow both landmark and building permit processes before altering historic properties. This guide explains which approvals are typically required, who enforces the rules, how to apply, and practical action steps for avoiding delays and penalties when working on landmarked or historic-resource buildings in New York City.

What permits and approvals are commonly required

For work on historic properties you will usually need approvals from the Landmarks Preservation Commission and construction permits from the Department of Buildings. Additional agency approvals may be required for work affecting streets, public plazas, or utilities.

  • Certificate of Appropriateness or administrative approval from the Landmarks Preservation Commission for exterior changes or demolition.Landmarks applications[1]
  • Building work permits from the NYC Department of Buildings for construction, façade work, structural repairs, and related trades.DOB permits[2]
  • Other permits or notifications for sidewalk sheds, street closures or sidewalk work where public right-of-way is affected.
Obtain LPC approval before filing for DOB permits to reduce rework and avoid stop-work orders.

Penalties & Enforcement

Enforcement for illegal or unpermitted work on historic properties is primarily handled by the Landmarks Preservation Commission for design violations and the Department of Buildings for construction and safety violations. Both agencies can issue orders, stop-work directives, and civil penalties; criminal charges are rare but possible when laws are willfully violated.

  • Monetary fines: specific fine amounts are not specified on the cited pages; see agency enforcement pages for details.LPC applications[1]
  • Escalation: agencies may issue initial notices followed by higher fines or daily continuing penalties for ongoing violations; exact ranges are not specified on the cited pages.DOB permits[2]
  • Non-monetary sanctions: stop-work orders, orders to restore or remove work, mandatory compliance plans, and civil court actions to compel remediation.
  • Enforcers and inspection pathways: the Landmarks Preservation Commission enforces design and landmark protections; the Department of Buildings enforces construction, safety, and permit compliance. To report or file a complaint, use the DOB complaints page.DOB complaints[3]
  • Appeals and review: appeals of LPC decisions may be available through LPC processes; DOB permit denials and enforcement orders have administrative review routes and may be appealed to tribunals or courts. Time limits for appeal are set by each agency and are not specified on the cited pages.
  • Defences and discretion: agencies may consider reasonable excuse, emergency repairs, or available variances; owners should document emergency conditions and seek retrospective approval when needed.
If work has already begun without approvals, stop and document before proceeding to reduce enforcement exposure.

The main application types are LPC certificates and DOB permit applications. Specific form numbers and fee schedules are published on each agency's site; where a form number or fee is not shown on the cited page, it is noted as not specified.

FAQ

Do I always need LPC approval before doing exterior work on a landmarked building?
Yes. Exterior work affecting a designated landmark or historic district typically requires LPC approval before permits are filed with DOB.
Can I get an emergency permit for urgent repairs?
Emergency repairs for safety may proceed but you should document the conditions and notify LPC and DOB; retrospective approvals may be required.
Where do I report unpermitted work on a historic building?
Report construction or safety complaints to the Department of Buildings via their complaints page; report design violations to LPC through their enforcement contacts.

How-To

  1. Identify the property's landmark or historic status and applicable district rules.
  2. Consult LPC guidelines and prepare an application package for exterior work if required.
  3. Submit LPC application and respond to requests for additional information.
  4. After LPC approval, file DOB permit applications with approved drawings and contractor filings.
  5. Schedule inspections, comply with orders, and retain records of approvals and permits.

Key Takeaways
