In San Bruno, it’s common for buildings to update systems on a schedule and to overwrite footage after a short retention window. Maintenance providers may also document repairs in ways that are not immediately accessible to injured people.
Acting early helps you:
- Preserve surveillance (and request the correct date/time range)
- Identify the responsible parties (building owner, manager, maintenance vendor)
- Secure incident reports and safety notices while they’re still “fresh”
- Connect your medical treatment timeline to what happened that day
