The Landmarks Preservation Commission (LPC) helps preserve the City's 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.
Owners or tenants must apply for a permit from LPC before doing certain kinds of work affecting the exterior and/or interior of landmark properties. In addition to filing the application form, applicants must provide certain documents and materials that explain the planned alterations. Learn more about how to get a permit.
LPC permits are required for the following exterior work:
- Any restoration, alteration, reconstruction, demolition, or new construction that affects the exterior of an individual landmark or a building in a historic district
- Any project that affects the exterior envelope of the building, even at parts of the building that are not visible from the street
LPC permits are required for the following interior work:
- Projects that require a permit from the Department of Buildings
- Projects that affect the exterior of a building, such as HVAC louvers and vents
- Projects that affect interior spaces that have been designated as interior landmarks
**PLEASE NOTE: Even if your exterior project does not require a Department of Buildings permit, a LPC permit is still required.
LPC permits are not required for ordinary repairs or maintenance such as:
- Replacing broken window glass
- Repainting a building's exterior or architectural feature a color that matches the existing color
- Replacing caulk around windows and doors
