Landmarks and historic districts: what designation by the Landmarks Preservation Commission means

How New York City designates individual, interior and scenic landmarks and historic districts, what an owner must do afterwards — permits, upkeep, fines — and how a landmark can sell its unused floor area.

A landmark in New York City is a building, an interior or a landscape the City has protected by law because of its history or its architecture; a historic district is a whole area protected the same way. Once a property is designated, almost any change to it — new windows, a rooftop addition, a demolition — needs a permit from the City's preservation agency first, and the owner must keep it in good repair.

For a buyer, an owner or a lender, designation shapes what a property can become. It does not freeze a building in time, and it does not change the zoning, but it adds a layer of review to every project and a duty of upkeep that never ends. It can also add value: a landmark may be able to sell the floor area it is not using.

The Landmarks Preservation Commission

The Landmarks Preservation Commission (LPC) is the City agency that designates landmarks and historic districts and then regulates changes to them. It was created in 1965 by the City's Landmarks Law, which the Commission itself describes as a response to the loss of historic buildings — above all Pennsylvania Station, demolished in 1963. The Commission has eleven members appointed by the Mayor and a staff of preservationists, architects, historians and lawyers; the law it applies is in Title 25, Chapter 3 of the Administrative Code.

The numbers are large. The Mayor's Management Report for fiscal year 2026 counted, as of June 30, 2026, 1,473 individual landmarks, 159 historic districts and extensions, and 38,550 buildings and sites protected in all. Most protected buildings stand in historic districts, not as individual landmarks. LPC's own About page, which carries no date, adds 125 interior and 12 scenic landmarks.

LPC does not regulate a building's use, density or floor area: those belong to zoning. A project that meets the zoning can still be refused by the Commission, and the other way round.

The four kinds of designation

An individual landmark is the exterior of one building or structure, from a farmhouse to a skyscraper. The Woolworth Building and the Empire State Building are individual landmarks.
An interior landmark is an inside space customarily open to the public — a lobby, a concourse, a theatre — such as Grand Central's concourse or the Empire State Building's lobby.
A scenic landmark is a City-owned park or landscape feature, such as Central Park, Prospect Park or Ocean Parkway.
A historic district is an area whose buildings together have a distinct sense of place, such as Brooklyn Heights, Greenwich Village or Tribeca. Inside one, LPC reviews changes to every building, including newer ones that are not historic themselves.

A landmark must be at least 30 years old and have special historical or aesthetic value to the city, state or nation. The owner's consent is not required, though LPC says it works to win the owner's support. Designation by the City is separate from listing on the National Register of Historic Places, a federal list run through the State; many New York City landmarks are on both, but the rules differ.

By BlockLot Intelligence's count of City Planning's lot file, 1,460 tax lots hold an individual landmark and 31,723 lots — 3.7% of all the city's lots — lie in a historic district, under 160 district names. The landmark count is close to LPC's 1,473 but not the same thing: a landmark can spread over several lots, and one lot can hold several landmarks.

Lots holding a landmark, and lots in historic districts

Borough	Landmark lots	In a historic district
Manhattan	957	11,873
Bronx	94	822
Brooklyn	206	15,191
Queens	97	3,635
Staten Island	136	202

Lots as City Planning's lot file marks them from the Landmarks Preservation Commission's maps. A lot is counted once, however many landmarks it holds; one landmark can cover several lots. BlockLot Intelligence, computed October 10, 2026.

Brooklyn and Manhattan hold most of the historic-district lots; Brooklyn's brownstone neighbourhoods — Park Slope, Brooklyn Heights, Cobble Hill — are among the largest districts by number of lots.

How a designation happens

From a first look to a designation the City Council can no longer change.

A designation starts with research: LPC's staff survey neighbourhoods, and anyone can ask the Commission to evaluate a property. The formal process opens with calendaring — a public vote to schedule a hearing. At the public hearing anyone may testify, and the owner, City Planning, the community board and local officials are notified. The Commission then votes; designation needs six votes and takes effect on the day of the vote.

Within ten days LPC files the designation with the City Council and the City Planning Commission. City Planning has 60 days to report on how it affects zoning and the City's plans, and the Council has 120 days from the filing to modify or reject it. The Council's approval is not required: if it does nothing, the designation stands. Since Local Law 76 of 2016, the Commission must act within 12 months of calendaring an individual, interior or scenic landmark — once extendable by another 12 with the owner's written agreement — and within 24 months for a historic district, or the item comes off the calendar.

A property that is only calendared is not yet protected, but the Department of Buildings may hold some permit filings on it for up to 40 days so LPC can review them.

What an owner must do

Designation puts three duties on an owner: get LPC's approval before starting work, follow the permit and its conditions, and keep the building in good repair.

Upkeep is a legal duty. Failing to keep a landmark in good repair — leaving it to decay until it must come down, which preservationists call demolition by neglect — is a violation in its own right, and LPC's penalty schedule sets the fine for a first offence at $3,500.

LPC permits

Almost any exterior work needs an LPC permit, even work the Department of Buildings (DOB) does not regulate, and even work that cannot be seen from the street. Inside, a permit is needed for work that needs a DOB permit, work that affects the outside, and any work in an interior landmark. Painting in the same colour, small repairs and emergency board-ups do not need one. LPC's staff issue about 95% of approvals without a hearing.

Permit	For	Decided by
Permit for Minor Work	Exterior work with no DOB permit	Staff
Certificate of No Effect	Work that needs a DOB permit	Staff
Expedited Certificate of No Effect	Some interior-only work	Staff, in days
Certificate of Appropriateness	Additions, new buildings, demolitions	The Commission, at a hearing

A Permit for Minor Work covers restoration or appropriate exterior work that needs no DOB permit — replacing windows in their openings, cleaning masonry, resurfacing brownstone. LPC says it often issues one within 10 business days of a complete application; the law gives it 20.
A Certificate of No Effect covers work that needs a DOB permit but does not harm what the designation protects — an interior renovation, new plumbing, rooftop equipment out of sight. Often 10 business days; the legal limit is 30. An expedited version for interior-only work filed by a self-certifying professional is measured against two business days.
A Certificate of Appropriateness is needed for work that changes protected features — an addition, a new building in a district, removing a stoop or a cornice. It goes to the full Commission at a public hearing, after a presentation to the community board; LPC says the whole process can take about three months, and the law gives the Commission 90 working days once the application is complete.

How fast it is in practice: in fiscal year 2026 LPC received 11,766 permit applications and issued 90% of Certificates of No Effect and Permits for Minor Work within ten business days, and 95% of expedited certificates within two, by the Mayor's Management Report. LPC's clock starts when an application is complete, not when it is first filed.

The Department of Buildings will not approve a filing on a designated property until the LPC permit is submitted. Applying to LPC is free; on work that also needs a DOB permit, LPC's fee is $95 for the first $25,000 of work and $5 for each further $1,000, collected by DOB.

Violations and fines

Work done without a permit, or against one, draws LPC enforcement. The usual first step is a warning letter, which gives the owner 20 working days to stop, correct the work or apply to legalise it, with no fine. Next comes a summons heard at OATH, the City's hearings office; admitting the violation and fixing it, or applying for a permit, at least 14 days before the hearing still avoids a fine. LPC can also issue a stop-work order. The owner is ultimately responsible, even for work a tenant did, and not knowing the building was designated is no defence. Under the penalty schedule in force since July 2024, a first offence on an exterior feature costs $500 and on a storefront $1,500. LPC has set a public hearing for November 17, 2026 on changes to its staff-level rules and its enforcement chapter, so these may change.

Selling a landmark's unused floor area

Many landmarks are smaller than the zoning would allow on their lot, and the law that protects them stops them from growing. The Zoning Resolution lets such a landmark transfer its unused floor area — its air rights — to another site. Since the City of Yes for Housing Opportunity amendment of December 5, 2024, the Chair of the City Planning Commission can certify a transfer to any lot on the same block, or across a street or an intersection, without a full land-use review. It can raise the receiving lot's allowance by up to 20%, or 30% in high-density commercial and manufacturing districts; a larger transfer, or changes to height and setback that go with it, needs a special permit. Landmarks inside historic districts became eligible too. Each transfer is permanent, is recorded with the City Register, and must come with a plan to maintain the landmark.

In East Midtown, around Grand Central, landmarks can transfer floor area to qualifying sites anywhere in the subdistrict, and each transfer pays 20% of its price — or of the City's valuation, if higher — into a fund for the area's streets and public spaces. The air rights guide follows one such transfer from Grand Central to Park Avenue in the public record.

A separate special permit lets the City Planning Commission relax use and bulk rules — but not the floor area — for a landmark or a building in a historic district, when that helps preserve it.

Tax credits

Landmark designation by the City brings no tax break by itself. The preservation tax credits depend on listing on the State and National Registers, not on LPC designation. New York State gives a credit of 20% of rehabilitation costs on an owner-occupied historic home in a qualifying census tract, when at least $5,000 is spent. For income-producing buildings the federal credit is 20%, and the State adds 20% or 30%, up to $5 million a building, through 2029.

A worked example: Grand Central and the Empire State Building

Grand Central Terminal, owned by the Metropolitan Transportation Authority, is both an individual and an interior landmark — City Planning's lot file records its lot as individual and interior landmark. Its lot of 134,203 square feet is zoned C5-3, a district that allows far more floor area than the terminal uses; in 2019 the City Council approved a tower at 270 Park Avenue, a few blocks north, built with 666,766 square feet of floor area transferred from the terminal.

The Empire State Building, owned by a company, is also recorded as an individual and interior landmark: the tower's exterior and its Fifth Avenue lobby. Any change to its facade or its lobby needs LPC's approval first.

How to check a building

LPC's Discover NYC Landmarks map shows every landmark and historic district, building by building, with links to the designation reports — the documents that describe what was protected and why, and against which LPC judges later changes. LPC stopped issuing status letters in 2023; the map replaced them. City Planning's lot file, PLUTO, carries each lot's landmark status and historic district name, though it does not mark scenic landmarks.

Questions people ask

What is the difference between a landmark and a historic district? A landmark is one building, interior or landscape; a historic district is an area. Inside a district every building is regulated, including newer ones, while an individual landmark protects the one property.

Can I renovate a landmarked building? Yes, with LPC's permit first. Most work is approved by LPC's staff in days or weeks; additions, new buildings and demolitions go to the full Commission at a public hearing.

Can LPC designate my building without my consent? Yes. The owner is notified and can testify at the hearing, and the City Council can modify or reject a designation, but the owner's consent is not required.

Does landmark status lower or raise property taxes? Designation itself does not change the assessment or bring a tax break. Preservation tax credits depend on listing on the State and National Registers, which is a different list.

Can a landmark sell its air rights? Yes. A landmark's unused floor area can be transferred to a nearby lot — on the same block, across a street or at an intersection — and in East Midtown to sites further away, with the City Planning Commission's approval.

How do I find out whether a building is a landmark? Look it up on LPC's Discover NYC Landmarks map. A block's page in BlockLot also names its historic districts and counts its landmark lots.
