Supportive housing holds 7 of Seattle's top 10 overdose-call addresses

What this chart asks

Which Seattle street addresses had the most 911 overdose calls, and how many are supportive housing?

Why it is shown this way

• A ranking, so sorted horizontal bars with the long place names on the y axis.
• Two colors with a key naming both, Supportive housing and Other place, so the share of supportive housing near the top reads at a glance without a gray-means-other convention.
• Intersections are left out because they are street scenes, not buildings.
• A callout marks the tie at the top: Hobson Place and The North Star logged 50 calls each.

Chart annotations

These markers provide relevant context for interpreting the chart. Their timing or position does not, by itself, establish causation.

   Reliability: Government. The City of Seattle publishes every Seattle Fire Department dispatch with its call type, address and time. The call type is set at dispatch from the caller's description.

2. Seattle Rental Property Registration (data.seattle.gov dataset j2xh-c7vt) Unit counts for registered rental buildings with 50 or more units (comparison group)

3. Seattle Fire Department 2025 Annual Report Total suspected-overdose responses (all substances) for 2023, 2024 and 2025, used to measure how much of them the overdose call type captures

4. King County Regional Homelessness Authority regional services database (resources.json) Program type, unit counts and barrier level for supportive housing programs

   Retrieved November 10, 2026. Public government data. Cited; building names and unit counts restated

   Reliability: Government. The regional homelessness authority's public map data of housing and shelter programs. It hides most supportive housing street addresses, so addresses were matched by building name to operator pages.

5. DESC housing buildings Addresses and units of DESC supportive housing buildings

   Retrieved November 10, 2026. Cited webpage. Cited; building names, addresses and unit counts restated

   Reliability: Other. DESC is Seattle's largest supportive housing operator and publishes a page for each building.

   Retrieved November 10, 2026. Public government data. Cited; addresses and unit counts restated

Limitations

• Counts only calls dispatched under the fire department's overdose call type, about a third of its suspected-overdose responses.
• A call usually means someone was treated or revived, not a death.
• Bigger buildings can get more calls; the dataset also gives calls per 100 units.
• Calls at an address can involve visitors, clinic patients or people outside.
