Washington DC Building Permits with Automated Geocoding

Building construction and alteration permits applied for and approved by the District of Columbia Department of Buildings. Addresses are batch matched to the District's Master Address Repository, though some points have 0,0 coordinates due to geocoding failures. The dataset was last updated on March 25, 2026.

Use Cases

• Map construction permit density based on geocoded location data.
• Analyze trends in building alteration approvals over time.
• Identify areas with potential geocoding errors for manual correction based on the described 0,0 coordinate issue.

Strengths

• Data is shared via an automated process for regular updates.
• Includes multiple file formats (CSV, GEOJSON, KML) for different analysis tools.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Some data points contain 0,0 coordinates due to failed automated geocoding, requiring manual correction.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
