Does Landmarks Preservation Commission (LPC) approval apply to my NYC building?

Landmarks Preservation Commission review applies to roughly 37,000 individually landmarked buildings and approximately 156 historic districts citywide — Greenwich Village, SoHo-Cast Iron, Park Slope, Fort Greene, Brooklyn Heights, Hamilton Heights, Crown Heights North, Tribeca East/West, and dozens more. If your building falls inside one of these jurisdictions, LPC sign-off precedes DOB permit issuance, and the workflow is parallel rather than sequential — you file at LPC and DOB simultaneously, but DOB will not release the permit until LPC closes its piece.

The legal basis is the NYC Landmarks Law (NYC Administrative Code §25-301 through §25-322), passed in 1965 and administered through 63 RCNY Chapter 2. Three permit types cover residential renovation work:

Certificate of No Effect (CNE) — interior or non-visible exterior work that has no effect on protected architectural features. Typical issuance: 5-20 business days. Most kitchen and bathroom remodels inside a landmarked apartment, where no exterior windows, facade, or original interior architectural feature is touched, qualify.

Permit for Minor Work (PMW) — small visible changes: like-kind window replacement using approved profile and material, in-kind masonry repointing with matching mortar, painting in approved palette, low-impact rooftop work. Typical issuance: 4-8 weeks.

Certificate of Appropriateness (COA) — substantive exterior changes, new construction in a historic district, additions, rooftop additions, storefront changes, or any work that alters protected architectural features. COA requires public hearing before the Commission, and timelines run 3-6 months minimum. The Commission can — and frequently does — require design modifications, sometimes wholesale.

Visible-from-public-thoroughfare is the operative test on exterior work. A rear-yard window in some districts is exempt; the same window on a street-facing facade triggers full review. Interior landmarks (Lever House lobby, Grand Central concourse, etc.) are the rarer case but apply the same framework.

Unauthorized work in a Landmarks district is a violation under §25-317.1 carrying fines up to $5,000 per day, plus a mandatory restoration order. DOB will not issue a Certificate of Occupancy until LPC closes its file.
