How this category is defined
What counts as building & housing maintenance: Complaints about the physical condition of buildings and housing — blight, code violations, failing plumbing and heat, unsanitary conditions, and property maintenance concerns on both residential and commercial properties.
In Chicago’s raw 311 data, the following 6 service_type values are counted as building & housing maintenance:
- Building Violation
- Buildings - Plumbing Violation
- No Building Permit and Construction Violation
- Restaurant Complaint
- Sanitation Code Violation
- Vacant/Abandoned Building Complaint
To reproduce these counts against the raw feed
SELECT count(*)
FROM <chicago_311_raw>
WHERE service_type IN (
'Building Violation',
'Buildings - Plumbing Violation',
'No Building Permit and Construction Violation',
'Restaurant Complaint',
'Sanitation Code Violation',
'Vacant/Abandoned Building Complaint'
)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.
