What data is readily available that can help shed light on the quality and composition of your housing stock?
Weave together the relevant data points
The key data points can be illustrated and woven together into a single narrative to demonstrate some basic facts for designing and targeting resources in your local housing strategy. Additional information that might be helpful regarding the quality and condition of your local housing stock might include trends over time or comparisons of your housing stock characteristics to those of other jurisdictions (e.g., the nation as a whole, the rest of the region, or other near-by jurisdictions) or even how needs vary across neighborhoods within your jurisdiction.

Issues of housing quality and condition add to New York City’s affordability challenges
Much of New York City’s housing stock is quite old with over two-thirds built before 1960 and only about 10 percent of the housing stock built since 2000, suggesting that much of it requires or has required capital improvements to remain viable and to meet current resiliency standards.
Housing code violations by community district in 2017, New York City
Neighborhoods with the highest levels of housing code violations are concentrated in the Bronx, southern Brooklyn, and northern Manhattan. Programs such as code enforcement and direct government assistance may be necessary to ensure these units meet minimum quality standards.
How many units are in the 100- and 500-year floodplains?
Also requiring attention the effects of climate change with some 100,000 housing units (2.9 percent of the housing stock) now in the 100-year floodplain and additional 114,000 units in the 500-year floodplain—amounting altogether to an important 6.2 percent of the housing stock.

The number and share of housing units that are studios and one-bedroom compared to the number and share of households that are one- or two-people households
Meanwhile in 2016, the number of studio or one-bedroom housing units (1.33 million or 38 percent of all housing units) appears to fall well short of the number of one- and two-person households (1.9 million or 61 percent of all households), possibly aggravating the affordability challenge in New York City for those who might be willing and able to live in smaller units.
