Top 50 street addresses for overdose calls

What this dataset measures

Built to answer whether some of Seattle's supportive housing buildings are among the city's top addresses for 911 overdose calls. The fire department's public dispatch log is the only public source that gives overdose calls by address. The city's rental registration list gives unit counts for a size-adjusted comparison.

Limitations and reproducibility

Reproducible from public data: README.md lists every API query. match.js and build_tables.js rebuild every CSV from the raw API responses. The dispatch log is live and can be revised, so a later pull may differ slightly.

• The overdose call type reflects what the 911 caller reported, not a diagnosis. It covers about a third of the fire department's suspected-overdose responses (33% in 2023, 34% in 2024, 36% in 2025); the rest are dispatched as general aid or medic calls.
• An overdose call usually means someone was treated or revived, not that someone died.
• The dispatch log has no patient identifiers, so repeat calls for the same person cannot be separated.
• A call to a building's address can involve a visitor, a clinic patient, or someone on the sidewalk outside.
• About 44% of overdose calls are logged at intersections (street scenes) rather than a street address; building rankings leave those out.
• The supportive housing list is fairly complete for DESC, Plymouth Housing, Chief Seattle Club, Catholic Community Services and King County Health Through Housing buildings, and partial for smaller operators. A fuller list would raise, not lower, the supportive housing share.
• 216 James St (17 calls) may be a side address of the Lyon Building; that was not confirmed, so it is not counted as supportive housing.
• Units for supportive housing come from operator and housing-authority listings; units for the comparison group come from the city's rental registration. A few buildings report slightly different unit counts in different sources.
