54-56 Sycamore St, San Francisco, CA 94110

The three-story multi-family residential building at 54-56 Sycamore Street in the Inner Mission, owned by Tam Yuen Sang & So Hang Rev, has undergone significant renovations since its construction in 1909. The most substantial work occurred in 2009, when major improvements were made to the lower unit, including a foundation replacement, lowering of the first-floor slab, and the addition of new bedrooms, bathrooms, and living spaces, totaling approximately $160,000. The building received comprehensive upgrades in 2009-2011, including window replacements, staircase reconstruction, and a new 200-amp electrical service with updated wiring throughout both units.

Building violations in 2010 related to interior surfaces, windows, heating, and security were all resolved by August 2010, and complaints about heating, window, and floor issues were addressed during this period. More recently, the property has experienced some maintenance challenges, including multiple instances of graffiti removal in 2024 and recurring issues with garbage and debris management documented through 311 calls. While there have been two fire alarm incidents recorded (both non-fire related), there have been no reported civilian injuries.

Recent building activity has primarily involved addressing exterior maintenance issues, as evidenced by multiple street space permits issued in 2018. The building's major systems receive regular attention, with multiple permits issued for plumbing and electrical work between 2009 and 2011, including heating system upgrades and new bathroom and kitchen installations. The property's history shows a pattern of substantial initial improvements followed by ongoing maintenance and repair work, with all major building violations from 2010 resolved and no active violations as of the latest records.
