Does my Work Require a Landmarks Permit?

Does Work on a Landmark Building Always Require a LPC Permit?

The Landmarks Preservation Commission (LPC, or aka Landmarks) has been issuing approvals and permits since their founding in 1965. The LPC strives to preserve historic districts and properties (or landmarks) by regulating the work done within them and on them. In most cases, Landmarks permits are issued when work affects historically protected features. Different permits exist, but are not applied for specifically, rather they are granted a type when the project is submitted. Interior projects are regularly issued Certificate of No Effects (CNE) while exterior projects are issued Permits for Minor Work (PMW) or CNEs. A Landmarks review ensures that work is done to adhere to various standards imposed by the LPC.

When are Landmarks Permits Required?

Landmarks permits are required whenever there are DOB permits being issued for the work. Although this requirement exists, there are some permits required from Landmarks when no DOB permit is issued. Most of this work covers both exterior and interior work, or anything that isn’t included on the list of exempt work. Some examples of work that will require permits includes:

  • Facade maintenance
    • Repointing bricks, patching masonry elements, restoring brownstone, restoring the facade’s masonry/wood elements
  • Exterior Alterations
    • This includes changing windows (in some cases), installing/replacing/restoring stoops, altering yards, and installing window AC units with brackets.
  • Interior Alterations
    • This typically includes interior renovations, as the work must satisfy LPC requirements. These permits are quicker to obtain than those of exterior alterations.

Permits are issued on a case per case basis. Some buildings may require LPC permits for the same work as other buildings that didn’t require it. It may be difficult to ascertain whether a project requires a permit or not. This includes “minor” projects which require contacting the LPC. For example sometimes permits are required for replacing windows, while other times they aren’t. If you are unable to contact the LPC, please contact us with your project. We find it better to look at the list of when Landmarks permits aren’t required, as these are clearly defined guidelines.

When aren’t Landmarks Permits Required?

Working on a Landmarked building will typically require permits, but the listed items are exempt from permits. In order to fully understand if a Landmarks permit is required, an application needs to be submitted. If you are unsure whether your project needs a permit please contact us. We have developed this list in combination with the LPC Townhouse Manual, used to inform owners on all things landmarked townhouse.

Have concerns about your project requiring Landmarks Permits?

We made this list as inclusive as possible to cover any typically asked questions. Most people want to know what can be done without a permit, hence the large list. Contractors and construction professionals require consulting for these topics as it isn’t clear from time to time. Work on landmarked buildings is highly regulated, and as such, so are the professionals working on them. Violations for work without a Landmarks permit will affect the ability to refinance a property and be costly/time-consuming to resolve.
