Zoning Permits (last 2 years)
Philadelphia L&I

Pulled from the city's Carto SQL API. Capped at 5000 most-recent permits per refresh. Geocoding is by the city L&I system and is decent but not perfect; ~1% of permits fall outside Philadelphia bounds and get dropped. Status field is normalized from L&I's free-text values with a best-effort mapping. The Zoning Board of Adjustment decisions dataset (which would have been a better fit) appears to have been retired from OpenDataPhilly.
