October 23 update: 413 → 418 research sites
Three existing housing properties and two planned projects added. Original 413 records and their research are preserved. Purple markers identify planned projects; teal markers identify the three new existing housing sites.
| New record | Address | Status |
|---|---|---|
| Jordan Apartments | 820 O’Farrell Street | Existing housing |
| 26th Street Cooperative Apartments | 3327-3331 26th St | Existing housing |
| McAllister Street Co-ops | 1840 McAllister St | Existing housing |
| The Marvel / La Maravilla — planned PSH project | 1979 Mission Street / 2970 16th Street | Planned / not operating |
| Laguna Honda senior housing — planned campus project | 375 Laguna Honda Boulevard — campus address | Planned / not operating |
DPH scope: March 2026 inventory counts units or services receiving DPH contributions, not full building capacity. It lists Jordan 54; La Maravilla 40 pipeline; Laguna Honda 40 pipeline; and 68 for the wider Co-Op program. The 68 are not assigned to either co-op building or to Jackson. The city portfolio reports ten treatment beds at each verified co-op; Conard describes three flats in each.
Not added: 2441 Jackson (office with historical residential use; current role unresolved) and the 13 master-leased co-op homes without verified addresses. The co-op properties are not the McAllister Hotel at 270 McAllister. The Senator remains at 519 Ellis in the baseline; DPH’s 519 Eddy entry is a source conflict, not a new dot.
Location precision: Jordan and the two co-ops use MOHCD portfolio coordinates. La Maravilla uses a Census address-interpolated site marker. Laguna Honda uses an interpolated campus street-address marker, not the future building footprint.

Historical reconciliation before this five-site update
The arithmetic is not a simple “431 minus 21 closures.” The original map contained duplicate/program-level entries, while the current inventory also gained legitimate sites that the earlier map did not contain. A separate 444-site historical master preserves current, closed, and temporary facilities so historical work is not lost.

The HTML contains all 418 map records internally, so the map data remain present even if the separate CSV/JSON files are moved. The Leaflet basemap itself requires an internet connection.
What went into this
This layer is the end product of a multi-stage reconciliation rather than a simple address list. Work included combining HSH, DPH, supportive-housing, shelter, behavioral-health and harm-reduction records; reconciling aliases and alternate street addresses; distinguishing programs from physical properties; consolidating multiple programs and floors within the same building; researching relocations and changed uses; adding missing current sites; preserving temporary and closed sites in a separate historical master; checking 2026 operating status; and resolving coordinates for every retained site.
During the historical build, 205 timeline events were reconciled against the earlier master, temporary facilities such as Safe Sleeping Sites and emergency hotels were researched, same-property duplicates were consolidated, and coordinate provenance/confidence was retained where possible. The result is designed for GIS analysis: one mapped point per physical site, while aliases, programs and historical context remain attached to the record.
Methodological caution: proximity on a map does not establish that an incident, overdose, arrest, service call or other event was caused by or connected to a facility. Spatial comparisons should be described as proximity or association unless independent evidence establishes a relationship.
