A searchable database built from New York City's public property assessment records is drawing sharp criticism over the privacy and security risks it poses to wealthy residents. The online tool, which aggregates and cross-references data from the city's official rolls, allows anyone to look up detailed information about individual properties — including the names of owners, assessed values, and tax histories. Critics say the platform effectively creates a map of high-value homes, making affluent New Yorkers targets for theft, harassment, or worse.
How the database works
The city's Department of Finance has long made property assessment records available to the public, but they were scattered across multiple files and required some effort to search. The new database, built by a third-party developer using publicly available data, organizes the information into a single, user-friendly interface. Users can search by address, owner name, or even filter by property value. For the first time, someone can quickly identify which homes in a given neighborhood are worth millions — and who lives there.
Privacy advocates argue that while the underlying records are public, the ease of access changes the equation. “Just because something is public doesn't mean it should be this easy to weaponize,” said one advocate who asked not to be named because of safety concerns. The database has already been used by real estate agents, journalists, and curious neighbors. But the worry is that criminals will use it too.
Privacy concerns for the wealthy
Wealthy residents are particularly exposed. The database doesn't just show property values; it often includes the names of individuals or trusts that own the property. For celebrities, business leaders, and others who value discretion, that's a problem. Some have gone to great lengths to hide ownership through LLCs or shell companies, but the database can still link those entities to physical addresses. In a city where high-profile figures are frequently targeted, the tool is seen as a gift to stalkers and thieves.
One Upper East Side resident, whose home is listed at over $20 million, said he was “shocked” to find his name and address easily searchable. “I've had issues with people showing up at my door before,” he said. “This just makes it easier for them.” He declined to give his name for this story.
Security risks beyond privacy
The concerns go beyond personal privacy. Security experts point out that the database could help criminals plan burglaries or even kidnappings by identifying homes with high-value contents and low visibility. “You can cross-reference property value with things like proximity to parks or corner lots,” one security consultant said. “It's a blueprint for a break-in.” The city has not commented on whether it plans to restrict access to the data or work with the developer to remove sensitive information.
Some have called for the city to at least allow property owners to opt out of having their names displayed. But the city's legal position is that the records are public by law, and removing names would require a change in state legislation. That's a slow process, and in the meantime, the database remains live.
What the city says
A spokesperson for the Department of Finance said the city is “aware of the concerns” but noted that the data is already public. “We are reviewing the situation and will consider any appropriate steps,” the spokesperson said in a statement. The developer of the database did not respond to requests for comment.
For now, wealthy New Yorkers are left to navigate a new reality: their homes are a click away from anyone with an internet connection. Whether the city will act — and how quickly — remains an open question.
