1623-1633 California St, San Francisco, CA 94109

1623-1633 California Street is a 3-story, 21-unit multi-family residential building constructed in 1923 and currently owned by 1623 California LLC. The building has undergone several significant improvements over the past decade, most notably completing mandatory soft-story seismic retrofits for both residential and commercial spaces in 2016, though at an increased cost beyond initial estimates. Recent major work includes a comprehensive laundry room remodel in 2020 affecting all 19 apartments, electrical service upgrades to 400 amps, and boiler-related improvements in 2022 including a new boiler installation and backflow device replacement.

The building has experienced several maintenance and safety issues, with the most recent violations in July 2024 related to fire safety requirements including smoke/carbon compliance, fire proofing, and fire escape maintenance, though these were abated by August 2024. Historical complaints indicate past concerns about construction communication, electrical work, and temporary service issues during improvements, as well as recurring fire safety inspections showing varying levels of compliance, particularly regarding extinguishers and sleeping area requirements. The building's systems have been regularly maintained and upgraded, with multiple plumbing and electrical improvements documented between 2007 and 2022, including water system updates, electrical panel replacements, and various fixture installations.

Recent 311 calls from 2024 primarily relate to street-level issues such as parking violations and waste cleanup, rather than building-specific problems. Fire incident records show mostly non-serious occurrences such as detector activations and system malfunctions, with no reported civilian injuries. The property has maintained active compliance with major safety requirements, including completing the soft-story retrofit program (classified as Tier 4 - Work Complete, CFC Issued) and addressing various building code requirements, though with some temporary violations that have generally been resolved.
