3679-3681 17th St, San Francisco, CA 94114

The three-story multi-family residential building at 3679-3681 17th Street, owned by Mission 81 LLC, has undergone several significant improvements since its construction in 1924. Most recently, in July 2023, the property received substantial maintenance work including the replacement of eight windows, siding replacement, and painting on the building's rear facade. The building completed its mandatory soft-story retrofit in 2017 at a cost of $80,000, bringing it into compliance with seismic safety requirements. Earlier improvements include stair repairs in 2017, electrical upgrades with ufer ground installation in 2018, and a proposed plan to convert the unfinished basement into two studio apartments (approximately 478 and 432 sq.

ft. each). The property experienced several compliance issues in 2011 requiring attention to fire safety and security features, including fire sprinkler systems, fire proofing materials, fire extinguisher maintenance, and security features such as door viewers and apartment identification. All these violations were abated by August 2011.

Historical records show various routine inspections and maintenance issues dating back to 1998, including concerns about peeling paint. More recently, there has been a noticeable pattern of driveway blocking incidents, with multiple citations issued between 2023 and 2025, particularly during 2023-2024. A carbon monoxide detector was activated in 2023, though no CO was detected and no injuries were reported. The building's parking management continues to be an ongoing concern, as evidenced by repeated parking enforcement actions in the surrounding area. The most recent permit activity and improvements suggest ongoing maintenance and updating of the property, with the soft-story retrofit completion signifying a major structural safety milestone.
