The Landmarks Preservation Commission (LPC) is a Charter-mandated New York City commission. LPC's powers and duties are set forth in detail in the New York City Administrative Code.

Rules for LPC practices and procedures, including requirements for receiving staff-level permits, can be found under Title 63 of the Rules of the City of New York.

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.
