534-536 Natoma St, San Francisco, CA 94103

The property at 534-536 Natoma Street is a two-story, four-unit multi-family residential building constructed in 1911 in the South of Market neighborhood. Significant recent improvements include comprehensive fire safety upgrades in 2019, with the installation of a new sprinkler monitoring system and modification of fire sprinklers throughout the ground floor, including the replacement of 25 sprinkler heads at a cost of $22,000. A major renovation project in 2015 added an additional ground floor unit with full amenities, valued at $320,000, following a previous violation in 1996 regarding improper ground floor unit usage.

The building's electrical system was significantly upgraded in late 2018 with the installation of new service equipment and multiple outlet installations in various units, followed by additional plumbing work including water heater and drain system modifications in 2018-2019. The building's maintenance history shows attention to safety concerns, with previous violations in 2004 related to rear staircase deterioration, security glazing, and fire safety issues all being resolved by April 2004. Recent fire department responses to the building have generally been for false alarms or non-emergency situations, with no reported civilian injuries.

The property has experienced ongoing basic maintenance needs as evidenced by multiple 311 calls in late 2024 for issues including flooding, sewage discharge, and garbage debris, though many of these cases have been promptly resolved. A recent fire alarm system inspection in May 2024 noted corrected conditions. The building's ownership has invested in substantial safety improvements over recent years, particularly regarding fire safety systems, while also maintaining the property's residential capacity through the addition of a ground floor unit.
