3937 Irving St, San Francisco, CA 94122

The two-story mixed-use building at 3937 Irving St in the Outer Sunset, owned by Woo Yee K & Sherry M, was constructed in 1955 and contains 6 residential units. The property has undergone several significant improvements over the years, with the most recent being a $25,700 fire alarm system upgrade in late 2024 to meet California/San Francisco Fire Marshall requirements, including the addition of low-frequency sounders in apartment units.

Earlier in 2024, substantial electrical work was initiated with plans for a new 200-amp mixed-use service including multiple residential and commercial meter sockets, and a wall gas heater replacement was completed. The building's history shows attention to seismic safety, with a seismic retrofit permit filed in 2014 for $65,700, and more recently, the property successfully completed the Mandatory Soft Story Program requirements as a Tier 4 building, receiving a Certificate of Final Completion (CFC) that signifies all necessary seismic improvements have been completed. While there was a concerning incident in 1997 involving severe water damage, mold, and lead paint issues, these were resolved within a month.

The building experienced multiple fire safety-related violations in 2002 (now resolved), including issues with fire extinguishers, emergency exits, and gas utility matters, but these were all abated by June 2002. Recent maintenance records show consistent attention to building systems, including a gas pipe repair in 2016, and completion of various plumbing and electrical upgrades in recent years. The property has had occasional street-level issues documented through 311 calls, primarily related to sidewalk cleanliness, but these are not directly related to the building's condition or management.
