1550 Hayes St, San Francisco, CA 94117

1550 Hayes Street is a three-story, nine-unit multi-family residential building constructed in 1928, currently owned by Joseph Campobello. The property has undergone several significant improvements over the past two decades, most notably completing its mandatory seismic retrofit as a Tier 3 soft-story building in 2014 (cost: $29,000), which included installation of foundation bolts and wall reinforcement. Recent unit improvements include comprehensive remodeling of Unit 8 in 2022 ($25,000) and Unit 6 in 2018 ($48,000), both involving kitchen and bathroom updates with modern electrical systems.

The building has faced various maintenance and safety issues over its history, with the most recent complaint filed in January 2024 regarding common areas, which remains active as of October 2023. A cluster of violations was documented in April 2016, including problems with smoke detectors, mold/mildew, plumbing fixtures, and interior surfaces, though these were officially abated by June 2016. The property has maintained active compliance with building codes since then, though previous issues included a 2001 complaint about rotting stairs and a removed roof door that was promptly addressed.

Infrastructure improvements have included roof replacement (2003), window replacement, and electrical system upgrades throughout various units. Recent external environment challenges have been documented through multiple 311 calls in 2023-2024, primarily regarding street cleaning and encampment removal, though these are neighborhood issues rather than building-specific concerns. The building's fire safety systems were reviewed in 2016 with minor issues noted regarding alarm systems and street numbering, with corrections verified by October 2016.
