632-634 Natoma St, San Francisco, CA 94103

The triplex located at 632-634 Natoma Street in the South of Market neighborhood is a three-story building constructed in 1907, currently owned by Sofia P Rillanos Revoc Lvg and consisting of three flats/duplex units. The building has experienced several significant maintenance issues throughout its history, with the most notable recent concerns emerging in 2020 when multiple complaints were filed regarding structural problems, including reports of the building tilting and rodent infestations in the basement. These structural and maintenance issues seem to indicate a pattern of deteriorating building conditions.

The property has undergone various repairs, including stair repairs in 2008 due to dry rot (costing $12,000 initially, revised to $8,000), and has addressed several safety concerns over the years. More recently, the building has faced ongoing fire safety compliance issues, with violations and complaints related to fire extinguishers and sprinkler systems as recently as 2023 and 2024. A violation was issued in October 2024 regarding sprinkler service and extinguisher service requirements.

The building's safety history includes multiple fire safety-related violations in 2008, including the need for fire extinguishers, removal of roof access ladders, and egress obstructions, all of which were subsequently abated. The property has also shown recurring issues with its fire suppression systems, as evidenced by the 2023 fire complaint regarding sprinklers/standpipe systems, which was corrected by November 2023. While the building's permits indicate some maintenance work has been performed over the years, including structural repairs and safety improvements, the recurring nature of safety violations and maintenance complaints suggests ongoing challenges with building upkeep and compliance.
