Q&A

CM Epstein questions on ADU and basement legalization pipeline

New York City Council · Sep 9, 2026 · starts 1:18:51 · 3 min 58 sec

Epstein asks about ADU progress and whether state legislative changes are needed. Levy reports 27 ADU applicants in pipeline with 17 more expected, noting challenges with pre-development work for homeowners. Tagani reports 261 applications under Local Law 27, with 48% for basement/cellar conversions, and says rules for manufactured ADUs and amnesty should be finalized by year-end.

Harvey D. Epstein

Chair, if I can just get another quick minute.

Harvey D. Epstein

I just want to talk to you about the ADUs.

Harvey D. Epstein

I know you mentioned how many ADUs have been developed now over the last year.

Harvey D. Epstein

Do you think we need to go back to Albany to either expand?

Harvey D. Epstein

Expand the pilot project or to extend the timeline of the pilot?

Commissioner Dina Levy

Yeah, so I just want to make a distinction between ADUs and the basement legalization, which is the pilot.

Commissioner Dina Levy

The Plus One program, which is the ADU program, is actually starting to really, I think, gain momentum.

Commissioner Dina Levy

challenging because the pre-development work that goes into designing the ADU, determining if there's enough space for a standalone unit, or whether it needs to be a conversion of an existing structure, takes time and actually resources and you need an architect, right?

Commissioner Dina Levy

So it's not really about code, it's just about

Commissioner Dina Levy

limited space.

Commissioner Dina Levy

We have about 27 ADU applicants in the pipeline right now moving forward and another 17 right behind them that we expect to enter the pipeline shortly.

Commissioner Dina Levy

We would like to keep moving that and again I think it's a question of making sure we have the right supports through our nonprofit partners for the pre, I would almost call it the pre-pre-development phase of the ADU development.

Harvey D. Epstein

I'm just wondering, one is, do you think that the strict kind of structures, not allowing more products to go forward, is there something we need to be doing differently on the state level to increase the flow of basements and ADUs?

Harvey D. Epstein

Yeah.

Commissioner Dina Levy

I mean, to be honest, I ran the ADU program for the state, and we found this to be challenging everywhere, including places where land is not so constrained or space, right?

Commissioner Dina Levy

So I think it's just a challenging thing in a very dense place like New York City.

Commissioner Dina Levy

That said, the amount of interest is overwhelming.

Commissioner Dina Levy

It's really exciting.

Commissioner Dina Levy

And the fact that we now have resources with which to finance that, along with the state resources, I think it's really not a legislative solution.

Commissioner Dina Levy

I think we need to just keep pushing hard on the front end for that pre-development phase.

Amin Tagani

More broadly under the local law.

Amin Tagani

27 piece, we actually have about 261 applications in.

Amin Tagani

Almost half, 48% or 126, are for basement and cellar conversion.

Amin Tagani

So we're seeing, to the commissioner's point, because of the constraint of land, we're really seeing attic, basement, cellar as being a main place where people are looking to deploy this opportunity.

Pierina Ana Sanchez

And thank you, Chair.

Pierina Ana Sanchez

Thank you.

Pierina Ana Sanchez

I just want to shout out the ADU4U tool.

Pierina Ana Sanchez

It's really nice looking at it last night.

Pierina Ana Sanchez

Did not work for my address, so I will be following up with you, Commissioner.

Pierina Ana Sanchez

I do want to know if I can have an ADU in my basement.

Pierina Ana Sanchez

Couldn't see that last night.

Pierina Ana Sanchez

But just since you mentioned the existing building code, Commissioner Tagani, you know, the kind of, that kind of guidance that the city is providing through ADU for you would be beautiful to see, you know, especially for small homeowners who, you know.

Pierina Ana Sanchez

Experience the city as a Byzantine regulator, it would be really helpful to, you know, if we can adapt that kind of guidance for small homes.

Amin Tagani

Absolutely.

Amin Tagani

So we've got a dedicated website.

Amin Tagani

We actually have a monthly newsletter.

Amin Tagani

Deputy Commissioner Sirakis has a crossword puzzle that he includes for those who want a game to understand more about the existing building code.

Amin Tagani

We've been signing up and doing seminars, webinars with different industry partners, and we'll continue to build out the website and those tools.

Amin Tagani

We also...

Amin Tagani

have implemented in our monthly industry meetings and our open webinar, our monthly online meetings with property owners and license reps.

Amin Tagani

So always open to do more, and especially if you want to convene property owners, we'd love to work with the council on that as well.

Amin Tagani

We're very focused on getting the word out about this.

Pierina Ana Sanchez

Great, excellent.

Pierina Ana Sanchez

Thank you.

Pierina Ana Sanchez

I'm going to turn it over now to Councilmember Caban, followed by Riley, and then Joseph.
