550-560 Guerrero St, San Francisco, CA 94110

The 6-unit multi-family residential building at 550-560 Guerrero Street, constructed in 1909, has undergone several significant renovations and faced various maintenance challenges over recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017 (Tier 3) at a cost of $90,000, demonstrating compliance with seismic safety requirements.

Recent improvements include multiple ongoing renovations in 2024, involving kitchen and bathroom remodeling on the second floor ($45,000) and corresponding electrical/plumbing upgrades, as well as water heater replacements and minor fire safety corrections ($1,700). The building has experienced several maintenance issues over the past few years, with the most recent problems documented in 2023-2024 involving hot water outages, water damage, and an electrical inspection citing hazardous wiring conditions. Historical records from 2019 indicated concerns with combustible materials and rodent infestation linked to construction debris, while a 2023 complaint suggests possible unauthorized rooming/boarding house operation.

The property has maintained compliance with fire safety inspections, with no significant fire-related injuries recorded in recent incidents, though there have been occasional smoke detector activations and gas leak calls. While most recent work demonstrates active maintenance and improvements, the building's history shows periodic infrastructure challenges, particularly relating to plumbing and electrical systems, as evidenced by multiple complaints and permits for repairs or replacements. The property has also experienced recurring issues with garbage and debris management, as documented in numerous 311 calls throughout 2024.
