3510 18th St, San Francisco, CA 94110

This three-story, 8-unit multi-family residential building located at 3510 18th Street in the Mission Dolores neighborhood, was built in 1923 and is currently owned by SF Multifamily 1 LLC. The property has undergone significant safety and infrastructure improvements in recent years, most notably completing mandatory seismic retrofitting in 2019 to comply with the soft-story program (Tier 4), and a fire alarm system upgrade in 2023 to meet current codes.

Other substantial improvements include reroofing work in 2020 ($29,850), sidewalk repairs, fence installation, and various plumbing and electrical upgrades. The building has experienced several construction-related complaints, particularly during 2020-2021, regarding noise during work hours and air quality concerns, though these issues were eventually addressed and resolved. The property's maintenance history shows attention to fire safety concerns, with some violations noted for fire extinguishers and alarm systems in 2015 and 2020, both of which were resolved.

Multiple 311 calls in late 2024 regarding graffiti and illegal postings suggest ongoing exterior maintenance requirements, though these are not indicative of structural or safety concerns. Two minor fire incidents were recorded, but no civilian injuries occurred in any of the documented incidents, and there have been no recurring patterns of serious violations or safety issues. The building's recent history demonstrates compliance with major safety requirements, including the completion of the soft-story retrofit, though there have been periodic concerns related to construction impacts on residents and some maintenance issues that required attention over the years.
