4170 17th St, San Francisco, CA 94114

The three-story, twelve-unit multi-family residential building at 4170 17th St in Corona Heights, constructed in 1904, has undergone several significant structural and safety improvements over the past decade. The property completed a mandatory soft-story retrofit in 2017 costing $122,000, demonstrating compliance with seismic safety requirements. Recent work includes an extensive $130,000 remodel in late 2024 involving kitchen and bathroom renovations in units 102-104, along with electrical upgrades and floor joist repairs.

The building has faced recurring maintenance challenges, particularly with heating systems, as evidenced by multiple tenant complaints about inadequate heat in 2018 and 2023, though these issues appear to have been temporarily resolved. Water intrusion has been an ongoing concern, with multiple complaints about leaks reported between 2020 and 2021 affecting unit 201. The building has undergone various essential repairs and improvements including window replacements in the bay window area (2020), and substantial electrical upgrades in 2024 with the replacement of multiple sub-panels across units.

Historical violations from 2000 regarding fire safety and security requirements were resolved by 2003. More recent fire safety compliance issues were addressed in 2023, including corrections to alarm systems and extinguishers. Maintenance history shows attention to structural integrity, with foundation repairs completed in 2010 and various plumbing improvements over the years, including recent work on shower pans and fixtures in 2024. While the building has experienced multiple maintenance issues, records indicate that most complaints have been addressed, though some problems such as inconsistent heating and water leaks have persisted over time.
