251-253 27th Ave, San Francisco, CA 94121

The 5-unit, 2-story multi-family residential building at 251-253 27th Avenue in the Sea Cliff neighborhood, owned by Ng Trust and constructed in 1971, has undergone several significant improvements in recent years, with the most substantial being a mandatory soft-story retrofit completed in 2019-2020 at a cost of $75,000, bringing the building into compliance with seismic safety requirements. The building has received regular maintenance and upgrades, including a complete kitchen and bathroom remodel in Unit 251 (2024), emergency fire panel replacement (2011), reroofing work (2001), and comprehensive fire safety improvements including a new fire alarm system with low-frequency sounders and device upgrades (2023).

Of particular note is a concerning water intrusion and mold issue reported in January 2022 in Unit 1, which was documented by Housing Inspection Services. The building's historical records show a cluster of fire safety violations in early 2001 involving egress obstructions, gas shutoff tool requirements, alarm system repairs, combustible storage issues, and fire proofing concerns - all of which were resolved by March 2001.

Recent improvements suggest active management attention to building maintenance and safety systems, including the relocation of unit electrical panels out of closets (2024) and updates to the fire alarm system (2023). The property has experienced recurring issues with illegal parking and sidewalk obstruction in the surrounding area, as evidenced by multiple 311 calls between 2021 and 2024, though these are external to the building itself. The building's soft-story retrofit work has been properly completed and certified, indicating compliance with current seismic safety standards.
