230 Oak St, San Francisco, CA 94102

230 Oak Street is a three-story, 20-unit multi-family residential building constructed in 1929, currently owned by The Spring St LLC. The building has undergone significant improvements over the past decade, including mandatory seismic strengthening work completed in 2016 under San Francisco's soft-story ordinance (Tier 2), which received a Certificate of Final Completion. Recent notable renovations include the addition of two new residences in 2017 valued at $200,000, and comprehensive unit upgrades in 2017-2018 involving kitchens, bathrooms, and associated plumbing and electrical systems.

The building's mechanical systems have been updated with a new boiler installation in 2020, though there have been recurring issues with boiler permit renewals, with the most recent violation recorded in February 2022. The property has maintained an active maintenance and upgrade schedule, including multiple unit renovations, street space permits, and various infrastructure improvements. Recent maintenance patterns show attention to both unit-specific and building-wide systems, including plumbing, electrical, and structural elements.

While there were several fire safety violations noted in 2009 related to fire alarm systems, fire escapes, and other safety features, these were all abated by 2014. The building's most recent 311 calls (2024) have primarily concerned exterior maintenance matters such as graffiti removal and sidewalk cleaning, with one recent report of sewage back-up discharge in December 2024. The property has retained its regulatory compliance status, with all major safety systems including the fire alarm system and soft-story upgrades properly addressed and documented, though it's worth noting that several 311 calls regarding exterior maintenance issues remain open as of late 2024.
