Direct answer
The short answer for San Francisco, CA
San Francisco towers, lobbies near transit, and tourist lodging need outbreak plans that start with the shared elevator core. Keep labeled wet times honest when fog-season HVAC runs with windows shut. Treat List N as a COVID-19 reference, not a sterile-building certificate.

Local planning context
In stacked towers and mid-rises, almost every trip passes a short list of shared objects. Call buttons, elevator panels, hallway rails, trash-chute handles, and package rooms near transit stops top that list. Say one floor reports a stomach bug, or a cold spreads while someone is contagious. Those elevator-core spots usually come before the decorative trim at the end of a hallway. In fog season, many windows stay shut. Chemical smells and wet film then dry differently than in a sunny courtyard building. Set empty-room times that match that reality, not a spray-and-go sales pitch.
Neighborhood lodging near tourist areas turns rooms over fast for late arrivals and same-day bookings. That pressure often shrinks an outbreak response into regular housekeeping. Linens get changed, bathrooms get wiped, and a scent is left behind. A real outbreak plan still needs an EPA-registered product matched to the germ. It needs detergent cleaning first and the full wet time, with the room or amenity kept empty. San Francisco Department of Public Health messages can support factual notices. They don't turn a condo gym or hotel hallway into a sterile clinic.
On many mixed blocks, street-level clinics and wellness shops share elevators and lobbies with apartments. Common-area work there is still community risk reduction under CDC cleaning and disinfecting advice. Medical device cleaning and hospital sterilization belong to the clinic's own program. They are not a standard for clearing homes. Cleanup sometimes uncovers blood or other body fluids that can carry disease. OSHA's blood rules may then cover the workers, even outside a hospital.
