Deputy Commissioner Sandler explains methodology for affordable housing targets

New York City Council · Oct 21, 2026 · starts 0:47:23 · 3 min 4 sec

He describes the methodology using population data, difficulty predicting affordable need, and says the 25% target comes from the mayor's housing plan; 50% of financed housing is for extremely low and very low incomes.

Michael Sandler

Sure, thank you.

Michael Sandler

So just on the affordable need, I think the HPD and the DCP team really dug in on the methodology that was outlined in the legislation and tried to meet the letter and the spirit of this bill to create a citywide framework for how

Michael Sandler

What is the city's need in terms of creating housing and how should that need be distributed across the 59 community districts?

Michael Sandler

When projecting out in 10 years, we sought to have kind of methodological rigor and numbers that we could stand behind and that...

Michael Sandler

Felt like they were kind of defensible.

Michael Sandler

And so you'll see in the needs analysis, we use population data.

Michael Sandler

We looked at who is already here in our city that doesn't have housing and what type of housing is near, how much housing is needed to meet that need.

Michael Sandler

And then also what type of population growth are we expecting from births, deaths, in migration, out migration.

Michael Sandler

And in terms of looking at the affordable need, it's very difficult to predict affordable need given the incredibly constrained

Michael Sandler

environment that we have right now in New York City, we see that the city's, you know, the AMI, which is how, you know, affordable levels are determined in affordable housing in New York City is based around market rent.

Michael Sandler

And so eligibility for affordable housing is based around the city's fair market rent and who needs and who qualifies for affordable housing is very kind of circularly dependent on that.

Michael Sandler

Availability of housing generally and what is housing costs in the open market.

Michael Sandler

And so we felt that it's very hard to know what the affordable housing need would be in 10 years if the broader housing growth has been met.

Michael Sandler

It's very difficult to predict.

Michael Sandler

And so we felt that what was kind of

Michael Sandler

made the most sense to share with New Yorkers is what we're committed to do on affordable housing and that we know that there's a very incredible need right now and the mayor's block by block housing plan

Michael Sandler

has incredibly ambitious targets for affordable housing greater than we've ever done before and so we're sort of basing around like what what's

Michael Sandler

What's our North Star for affordable housing is based around those targets in the housing plan.

Michael Sandler

On the, I guess, sticking with that for a second, your question about why was the citywide target for affordable housing 25%?

Michael Sandler

Again, that goes back to the affordable targets for the growth, for the...

Michael Sandler

Fair housing growth strategy come directly from the mayor's housing plan.

Michael Sandler

So unlike the broader kind of overall housing growth projections, the affordable targets are what we're budgeting for and what we're planning for and what we want to hit.

Michael Sandler

So those are the targets that come directly from the housing plan.

Michael Sandler

And the 25% is really a function of that's just what percent those targets are of that overall housing production that we're targeting for the city.

Michael Sandler

And then in terms of the deeply affordable target, again, those come from our budgeted projections through the housing plan.

Michael Sandler

We create affordable housing through a mix of as-of-right programs that have affordability levels that are set by those programs.

Michael Sandler

And then on the housing that we finance, 50% of that housing is for extremely low and very low incomes.
