4300-4308 23rd St, San Francisco, CA 94114

The 6-unit, 3-story multi-family residential building at 4300-4308 23rd Street in Noe Valley, owned by Horwitz Marital Trust, was constructed in 1911 and has experienced several significant events throughout its history. Most notably, the building suffered fire damage in 2015 when an electrical short affected the ground floor grocery store, prompting extensive repairs and system replacements, including a new sprinkler system installation in 2017-2019. The property has undergone mandatory soft-story seismic retrofitting as a Tier 3 building, with work completed and Certificate of Final Completion issued, though there was a complaint filed in 2020 regarding initial non-compliance.

Recent improvements include a completed bathroom remodel in November 2023 and final inspection approvals in September 2023. The building's safety systems have been actively maintained, with a like-for-like fire system replacement in 2019 and regular fire alarm system monitoring. The property has maintained compliance with most building codes since addressing multiple violations in 2002 related to electrical systems, smoke detection, and fire safety, all of which were abated.

Minor electrical issues, including several instances of alarm system malfunctions and smoke detector activations (none resulting in injuries or fires), have been documented in recent years. Infrastructure improvements include plumbing upgrades, such as new gas lines installation in 2020, and various street space permits in 2018-2019. Regular maintenance and prompt attention to repairs suggest active property management, though there have been occasional reports of garbage and parking issues in the vicinity as documented through 311 calls, all of which were resolved.
