The Landmarks Preservation Commission (LPC) helps preserve the City's designated landmark properties by regulating changes made to these buildings and sites. We do not prevent owners from making changes, but rather work with them to ensure that planned changes are appropriate to the character and style of the building and/or historic district. 


All LPC permit applications are now filed and processed through Portico, the agency’s new web-based permit application portal. By logging into Portico, owners of designated landmarked properties can apply online for LPC permits, upload supporting documents, track the progress of their applications in real-time, and seamlessly download final permits. LPC no longer accepts any filings or related materials outside of Portico.  

  • Do not email PDF forms, drawings, or other materials directly to LPC staff or to any of the LPC email addresses previously used to email applications.
  • Do not mail, messenger, or bring paper application forms, drawings, or other materials to the LPC office.

There are two types of filing categories: New Applications and Post-Approval Actions.

  • For New Applications, Portico will automatically determine the service for which your application qualifies. Some types of work are eligible for LPC’s expedited review services, where LPC’s expert staff can review and more quickly issue permits. If your proposed work qualifies for Business Express Service, FasTrack or an Expedited Certificate of No Effect (XCNE), Portico will automatically direct your application to the correct service.
  • Post-Approval Actions include amending previously-approved work (changing or adding to a previously-approved scope of work), extending an active permit before it expires, signing off on previously-approved work (including requesting review of work done to correct a violation, and submitting final filing drawings for Certificate of Appropriateness permits

The City's Landmarks Law requires owners to obtain permits from the Landmarks Preservation Commission before doing work that affects the exterior and, in some cases, the interior of a designated landmark property. Owners or representatives from the owner’s project team (e.g., architects, commercial tenants, preservation consultants) must apply for a permit from LPC before doing certain kinds of work affecting the exterior and/or interior of designated landmark properties.

To obtain a permit, applicants must file a completed application that includes supporting documentation such as photographs, architectural plans, and presentations that explain the proposed work.

Our LPC Permit Guidebook will help prepare you for submitting a completed application, including more information on staff-level approvals. If an application is complete upon submission, a permit can often be issued upon initial review.
