Seattle 911 overdose calls by address, 2023 to October 2026

Top 16 street addresses for overdose calls

Question: Which Seattle street addresses had the most overdose-coded 911 calls from January 2023 to October 2026, and what is at them?

Result: 7 of the top 10 street addresses for overdose calls, and 9 of the top 16, are permanent supportive housing. Hobson Place and The North Star, both run by DESC, tie for first with 50 calls each.

Operation: Sum overdose-coded calls by address over the four periods; drop intersections; rank; keep ranks 1 to 15 (16 rows with a tie at 15); label each with its place and whether it is supportive housing

Scope: Seattle street addresses (intersections excluded)

View this analysis

• Counts only calls dispatched under the overdose call type, about a third of the fire department's suspected-overdose responses.
• Calls at intersections, 44% of the total, are excluded.
• Calls at an address can involve visitors, clinic patients or people outside.

Robustness checks

• Alternative comparison: Overdose calls per 100 units per year. Adjusting for size: supportive housing logged 3.65 overdose calls per 100 units per year, against 0.10 for other registered rental buildings with 50+ units, about 36 times as many.
• Sensitivity analysis: Overdose share of medical calls. Overdoses are 3.35% of medical calls at supportive housing and 2.25% citywide, so supportive housing gets more medical calls of every kind; a different labeling habit would not explain a 36-fold gap.

Overdose calls per 100 units per year

Question: Size aside, how often are overdose calls logged at supportive housing compared with other large rental buildings?

Result: Supportive housing: 600 calls across 4,287 units, 3.65 per 100 units per year. Other large rental buildings: 437 calls across 111,092 units, 0.10 per 100 units per year, about 36 times fewer.

Operation: Sum calls and units for each group; divide calls by units, times 100, divided by 3.833 years

Scope: 57 supportive housing addresses; 819 other registered rental addresses with 50+ units

• Unit counts come from different sources for the two groups.
• The comparison addresses must match the dispatch address exactly; a building whose calls are logged under another address would be undercounted. The same applies to supportive housing.

Supportive housing share of overdose calls by year

Question: What share of all overdose-coded calls were at supportive housing addresses each year?

• The supportive housing list is partial for smaller operators, so these shares are lower bounds.

Overdose share of medical calls

Question: Do supportive housing addresses label a larger share of their medical calls as overdoses?

Result: Supportive housing addresses logged 6.0% of Seattle's medical calls and 8.9% of its overdose calls. Overdoses were 3.35% of their medical calls, against 2.25% citywide.

• Medical types include many reasons for a call; this is a rough check, not a measure of each call's cause.

How much of the fire department's overdose work the call type captures

Question: What share of the fire department's suspected-overdose responses were dispatched under the overdose call type?

• The annual report's total counts responses the department judged to be suspected overdoses, which may be decided after dispatch.

Top 20 locations for overdose calls, intersections included

Question: Where do supportive housing buildings rank when street intersections are counted as locations too?

Result: Counting intersections, the top four locations are downtown and Chinatown-International District street corners. Hobson Place and The North Star tie for 5th. Supportive housing holds 3 of the top 11 locations (a tie at 10th) and 7 of the top 20; intersections hold 7 of the top 11 and 11 of the top 20.

Operation: Sum overdose-coded calls by location (street address or intersection, upper-cased) over January 2023 to October 2026; rank all locations; ties share the higher rank; keep ranks 1 to 20

Scope: All Seattle dispatch locations, including intersections

View this analysis

• An intersection collects calls from a whole corner, often from people outdoors, so it is not comparable with one building's address.

All medical calls per 100 units per year

Question: Using every aid and medic call, not only those dispatched as overdoses, how do supportive housing buildings compare with other large rental buildings per apartment?

Result: Supportive housing logged 108.9 medical calls per 100 units a year, against 7.7 in other large rental buildings, about 14 times as many. For calls dispatched as overdoses the gap is about 36 times.

Operation: Sum all dispatch types containing Aid or Medic (excluding mutual aid) by address, January 2023 to October 2026; sum over each group; divide by units and by 3.833 years

Scope: 57 supportive housing addresses; 819 other registered rental addresses with 50+ units

View this analysis

• Medical calls cover every kind of emergency, not only overdoses, so this is a broad check, not an overdose count.

Results without Hobson Place

Question: Does the result depend on Hobson Place, whose address also hosts a clinic open to the wider community?

Result: Without Hobson Place, 6 of the top 10 street addresses are still supportive housing (The North Star, Almquist Place, The Morrison, Bertha Pitts Campbell Place, the Lyon Building and Plymouth on First Hill), and supportive housing logs 3.41 overdose calls per 100 units a year (550 calls, 4,202 units).

Operation: Repeat the street-address ranking and the per-unit comparison with 1911 22nd Ave S removed

Scope: Seattle street addresses; 56 supportive housing addresses

• The Morrison's address also hosts a clinic and an opioid treatment center; it was not removed in this check.

Overdose calls per 100 units a year at the busiest supportive housing buildings

Question: Per apartment, how often are overdose calls logged at the supportive housing buildings with the most calls, compared with other large rental buildings?

Result: The 10 supportive housing buildings with the most overdose calls logged between 5.49 and 15.35 overdose calls per 100 units a year. All supportive housing averaged 3.65 and other rental buildings with 50+ units 0.10.

Operation: For each supportive housing building with 20 or more overdose-coded calls from January 2023 to October 2026: calls / units x 100 / 3.833 years. times_other_buildings_rate divides by the unrounded rate for other registered rental buildings with 50+ units (437 calls / 111,092 units / 3.833 years x 100 = 0.1026).

View this analysis

• Counts only calls dispatched under the overdose call type, about a third of the fire department's suspected-overdose responses.
• Calls at an address can involve visitors, clinic patients or people outside; Hobson Place and The Morrison host clinics.
• Some low-income buildings in the comparison group come close to the supportive housing average; The Frye (LIHI) logged about 3.8.
• A call usually means someone was treated or revived, not a death, and one person can account for several calls.
