CM Brewer Q&A: Mangin on rent-regulated housing and zoning lot mapping

New York City Council · Sep 1, 2026 · starts 3:14:37 · 3 min 43 sec

Brewer asks about rent-stabilized housing being demolished for market-rate development, citing a Gary Barnett building on 96th Street. She then asks about creating a zoning lot map. Mangin says zoning lot determinations require months of historical research and creating a legally effective map remains impossible, citing the 200 Amsterdam case.

Shaun Abreu

I think you explained that the only affordable housing you counted was income restrictive housing.

Shaun Abreu

Most affordable housing in New York City, but particularly in Manhattan, is rent stabilized or even rent controlled.

Shaun Abreu

Can you talk about the role of rent regulated housing in the city's affordability crisis?

John Mangin

Thank you for the question.

John Mangin

I mean, rent stabilization is absolutely essential to the New York that we know.

John Mangin

It's an absolutely essential affordability measure.

John Mangin

It's not the only thing that we can or should do to support affordability and affordable housing in New York City, but it's a crown jewel of that system of regulation.

Shaun Abreu

So how would you support rent-regulated housing?

Shaun Abreu

Because in some cases it gets torn down to build rent-restricted.

Shaun Abreu

How would you deal with that?

John Mangin

In the post-urban renewal era, I would say that demolition of large amounts of housing is relatively limited, fortunately.

Shaun Abreu

Well, Gary Barnett just did it on 96th Street and Broadway.

Shaun Abreu

Entire building is empty, was 100% rent stabilized.

John Mangin

That's regrettable.

John Mangin

I didn't understand that building.

John Mangin

I would want to look into it more closely.

Shaun Abreu

All right.

Shaun Abreu

In response to a council bill that would require the city to make and maintain a map of

Shaun Abreu

zoning lots, you supported the Department of City Planning's position that the making of such a map would be impossible.

Shaun Abreu

Do you still believe that creating a map of zoning lots is impossible?

Shaun Abreu

The reason I ask, I've done 200 some ULURPs, maybe more, and often the map that is zoning is very strangely

Shaun Abreu

designed and the buildings that end up, we have no idea how they get to be merged in such a weird way.

Shaun Abreu

And then we go to court and we lose.

Shaun Abreu

We want to know about the lots.

John Mangin

Thank you for the question, Councilmember.

John Mangin

I mean, I personally have been involved in months-long processes.

John Mangin

To try to figure out whether a given set of tax lots was in fact a zoning lot or not.

John Mangin

It implicates historical and transactional information that can date back to pre-61, that in some instances can date back

John Mangin

even before the zoning resolution.

John Mangin

And given that in many instances, determining whether or not something is a zoning lot takes that much work, that much historical sleuthing, and may end up in court anyway,

John Mangin

Yes, it was and it remains completely impossible to create like a legally effective map.

John Mangin

of what is and what isn't a zoning lot in New York City, and DOB will certainly tell you the same thing.

Shaun Abreu

But doesn't that make it hard then to fight for housing that is, in our case, too tall, bought too many lots, et cetera?

Shaun Abreu

You don't have any sense of that without the lots, right, without the map.

John Mangin

You did have a case in your district.

Shaun Abreu

200 Amsterdam Avenue.

John Mangin

Extremely, extremely complicated.

John Mangin

And that, you know, through your advocacy led to changes in how zoning lots are administered in New York City.

John Mangin

But you recognize through that process how intensive it can be.

John Mangin

Time intensive it can be just to figure out the status of one little plot of land.

John Mangin

So to try to do that for the hundreds of thousands, if not millions of lots across the city, it's just not something that's possible.
