Sam Daly SF SROs

San Francisco’s residential hotels

SROs are the city’s remaining residential hotels — one room, usually a shared bath, often the cheapest housing still standing. DBI keeps the legal list. Planning counts the rooms. The map uses both.

Official citywide stock. For-profit hotels also have 2,312 tourist rooms on the same parcels — not in the residential total.

Who operates them

Each hotel is for-profit or nonprofit, not both. Nonprofits run fewer buildings and more rooms in each.

Stock, 2021–2025

Net change is small. Rooms moved from for-profit to nonprofit more than they disappeared.

Vacancy

There is no public vacancy file for the 497 hotels. DBI still collects empty rooms every October and posts who filed, not the counts. The live HSH dashboards are a different stock: city supportive housing, hotels and apartments mixed, no SRO column. A current rate exists. The monthly count chart stops in May 2023.

On the map

Data, so you can argue with it

The charts read data/hotels.json. Citywide totals are DBI’s, published in Planning’s Housing Inventory. Building dots and room counts are Planning land use (restype = SRO) joined to the 2024 AUUR address list and the Assessor year-built field. That is not DBI’s certified room-by-room HCO file. If a count looks wrong, file an issue.
