Mamdani Publishes Names, Addresses of NYC Homeowners Facing New Pied-à-Terre Tax

New York City Mayor Zohran Mamdani's administration has unveiled a database listing property owners impacted by the new pied-à-terre tax aimed at luxury second homes. , US News, Times Now

The administration of New York City Mayor Zohran Mamdani has published a searchable database identifying property owners whose homes could be affected by the state's new pied-à-terre tax, prompting criticism over privacy and security concerns.
The database, released by the city's Department of Finance, lists the names and addresses of owners of non-primary residences across the five boroughs that are valued at more than $1 million. The tax is intended to target luxury second homes, but critics argue the list includes many properties that may not qualify.

Seems like a pretty irresponsible move...

"Hey, here's a list of people who have money, and here's the addresses of residences they have that most likely won't have anyone in them" seems like a "Hey burglars, if you're looking for a property that likely has some items of value, and nobody currently in them, here's some good options"

Apologies for the selected sources for this story...but as usual, the mainstream outlets aren't really covering it.

And that's because it's not newsworthy. Go visit this site for example: https://www.propertyshark.com/Prope...ide_location=Brooklyn, NY&sort=sale_date:desc

Want to know where the rich people live in an area, a borough or even a street? Brooklyn maybe? Just fill in the filters, put in a min and max dollar figure and you're good to go.

Ooh, look. 317 MacDonough Street in Brooklyn is worth $2m. Chip in and become a site member and you can get the owner's name as well.

"where rich people live" isn't the main issue. Virtually everyone knows which neighborhoods in their cities have the upscale homes.

Yes, you can see the ritzy homes (and their addresses) on Zillow or any realtor website as well.

It's the fact that it's filtered down list homes that would be subject to this pied-à-terre tax. Meaning, 2nd homes that are owned by wealthy non-residents, and that aren't used a primary residence, and name searchable.
(which Mamdani had announced on social media telling affluent New Yorkers to "check your mailbox" as notices went out, which primed the release to be read as a taunt rather than a statutory filing)

In other words "Here's a list of (likely unoccupied much of the time) homes owned by those evil rich people that us DSA types were talking about", and a popular mayor (with millions and millions of social media followers) amplifying the release.

Are property tax rolls private in most cities?

Tax rolls don't indicate which homes may be unoccupied.
The governor should be focused on governing rather than being an activist against the city's entrepreneurial community. His time could be better spent filling pot holes.

This database is of apartments that are not primary residences, not unoccupied - there is a tremendous distinction. Any given property may be unoccupied at any given time - or occupied by those who prefer to maintain a primary resident in a state that does not tax income, by relatives, by renters, or that function illegally as Air-B&Bs.

A city won't become financially solvent by giving those who pay the taxes a reason to leave. Ask California and its governor.

There is always a reason to leave just as there are reasons to stay. As long as NYC is the financial and cultural center of the country obscenely rich people will maintain their pied-a-terres.

This tax is a step toward solvency - a much better one than the previously tried deferred maintenance or clearing poor housing to make way for the rich with decades-long tax abatements (see Trump's J-51 boondoggles).

I would imagine there's probably some variance across cities.

However, making a specific list of available of which ones specifically aren't primary residences in one easy to find file, and highly publicizing it is unique.

The main argument the critics have is that database goes beyond ordinary public records by making it an easy aggregated "one stop shop". The general idea being that bundling individually-public records into one downloadable file destroys the practical obscurity that granted some privacy protections.

DaisyDay said:

The CSV's also have coding to indicate which are declared as rentals vs. which ones aren't.

So it does actually give a bit of an indicator as to which ones are more likely to be unoccupied.

If I owned a second home in a city that was currently being ran by a mayor who stirred up some anti-wealth animus, and that also had "squatters rights protections", and published easy comprehensive list of "Hey, here's the 2nd homes where nobody is likely in them, and the owner probably down in Florida for months at a time", I wouldn't be too thrilled about it.

The argument from the people defending the release of the list on the grounds of "well yeah, but that was all technically a matter of public record that someone could find online anyway" isn't a fair argument based on the practical obscurity aspect I mentioned before.

As an example:
Divorce records are a matter of public record, if one wanted to spend weeks and months of their free time scouring various court public records portals, they could probably figure out everyone in their county who's gotten divorced, and read the docs to see which ones were due to marital infidelity.

That's very different than if a Mayor spent months demonizing people who cheat on their spouse as scum of the earth and the enemy, and then aggregating all of those specific public records and releasing it in one easily searchable purpose-driven database by name/address, and then hopping on Twitter to say "Hey, you know those terrible cheaters I was talking about who are undermining the institution of marriage, hop on our website so you can download the full list of them to see the ones in your neighborhood"

I would imagine there isn't as property and tax records are one of the fundamental functions of government. Let me know if you find a municipality that has such records that are NOT available to the public.

Who "highly" publicized it, Mandani or his detractors? Are the stories accurate?

Does it, though? What privacy is granted to property owners concerning whether or not their property is their primary residence generally? Tell me what the privacy concern is that trumps public record transparency.

Is that also a grievous privacy violation?

How? Are you really unaware of the gray market in apartment rentals and subletting? Not being a primary residence of the owner does not mean unoccupied as - this may come as a surprise - many people have relatives! And friends!

Figure out? You mean by looking at the public records? Question - which states make the details of divorces public and which ones still have infidelity as a factor?

Another ridiculous, inappropriate analogy.

What makes you think that property tax records don't already include whether or not a property is a primary residence?

Under the typical systems, if some social justice vigilante wanted to aggregate all of the names and addresses of people who have a non-primary, non-rental residence valued at over $1M in NYC, it would have taken them quite a long time doing it the old fashioned way.

Now, they can do a 2 second download and open it in Excel and get their potential hit list.... oh sorry, I mean "Not paying fair share accountability" list

Of course, they wouldn't do anything nefarious with that information right???

It's not like Mamdani announced this specific tax by giving away a rich person's personal address in a highly publicized way...oh wait

Mamdani responds after billionaire slams NYC mayor's rich tax video

Last week, Griffin's company, Citadel LLC put out a statement to its employees slamming the use of the CEO's $238 million home in Mamdani's video.

www.usatoday.com

And the analogy isn't inappropriate or ridiculous, it's similar to what happened.

Mamdani has demonized wealth and wanting to pay less in taxes non-stop and claimed "they're not paying their fair share", and now his office has published a nice concise searchable list where people can go if they want to "teach those greedy rich people a lesson"

Well sure...if Mamdani is going to suggest that them not paying enough in taxes, or seeking tax relief by establishing primary residence in another state is the reason why poor people aren't getting enough help. That would imply "evil" and "greedy" would it not?

Accusing one of not paying their fair share and not caring about poor people implies exactly that.

If by "clearing poor housing to make way for the rich", you mean clearing the sidewalks of tents and cardboard shacks so the general public can use the sidewalks, then I don't see a problem.

Frustrating that if my post is quoted it un-unsubscribes me.

No, it doesn't imply any such thing. I don't know anyone dumb enough to imply that. My son has bought a residence as an investment. He rents it out. He has an accountant that explains to him what he is allowed to do to minimise any tax he has to pay. Only an idiot would say that that would make him evil and greedy.

ThatRobGuy said:

Likewise only an idiot would say that by following the tax laws and paying no more than he is obliged to pay means he doesn't pay his fair share. He is, by law, paying his fair share. And only an idiot would say that as he has put his money into a property as an investment would say that he doesn't care about poor people.

And 'paying enough in taxes' simply means the same...paying what you are legally bound to pay. If Mamdani wants to raise taxes then 'paying enough in taxes' means that some people will be paying more. He will raise them because he believes that the money raised is needed to help fullfill the promises on which he was elected.

As I said, your comments tell us a lot more about your attitudes than it does about Mamdani or anyone who has a second residence.
