In Baltimore’s raw 311 feed, the following 4 service_type values roll into building & housing maintenance:
- HCD-Maintenance Structure
- HCD-Sanitation Property
- HCD-Vacant Building
- SW-Boarding
To reproduce these counts against the raw feed
SELECT count(*)
FROM <baltimore_311_raw>
WHERE service_type IN (
'HCD-Maintenance Structure',
'HCD-Sanitation Property',
'HCD-Vacant Building',
'SW-Boarding'
)Analyst tip: This is where NYC's HPD-style housing complaints live: 'HEAT/HOT WATER', 'PLUMBING', 'PAINT/PLASTER', 'DOOR/WINDOW', 'UNSANITARY CONDITION'. Chicago uses the single catch-all 'Building Violation'. Baton Rouge uses 'BLIGHTED PROPERTIES' and 'BUILDING CODE/ZONING VIOLATIONS'. Expect this category to be large in cities with aggressive code enforcement.
