The Landmarks Preservation Commission Rules are found in Title 63 of the Rules of the City of New York, available through an online portal that contains all of the city rules.

Helpful tip: Use the navigation column on the left to see all the titles and chapters under the Rules of the City of New York. Click on the plus sign to expand the tabs ad then click on the relevant title or chapter.

These rules set forth the Commission's application and public hearing procedures, and the rules and standards for work on buildings in historic districts and individual landmarks. Proposed work that meets the rules may be approved by the LPC staff. If proposed work does not meet the rules, the application must be reviewed by the full Commission at a public hearing.

To assist owners of landmark buildings and sites, LPC has created manuals that explain these rules and regulations, as well as guides for how to get permits for alterations as quickly as possible. See the Permit Application Guide and Technical Resources.
