NYC Community District Housing Unit Changes Since 2010

NYC Department of City Planning's Housing Database tracks net changes in housing units for New York City Community Districts. It aggregates data from Department of Buildings-approved construction and demolition jobs filed or completed since January 1, 2010. The dataset includes census unit counts, net changes, and units pending completion.

Use Cases

• Analyze annual housing unit completion trends using columns like comp2010, comp2011 through comp2024.
• Model the relationship between units in different approval stages (filed, approved, permitted) and final completions.
• Map spatial distribution of housing growth or decline by joining community district geometry (the_geom) with unit change metrics.
• Forecast future housing stock by using historical completion time series from 2010 to 2024.
• Assess project attrition rates by comparing counts of filed, approved, and withdrawn or inactive units.

Strengths

• Provides 15 years of annual completion data from 2010 to 2024.
• Includes multiple status indicators per project (filed, approved, permitted, completed).
• Covers all New York City Community Districts with geospatial boundaries (the_geom).

Limitations

• Sample size (number of rows/community districts) is unspecified.
• Data relies on administrative filings which may have reporting lags or errors.
• Does not include detailed project-level attributes like building type or affordability.
