AI summary

The 12-unit, 3-story multi-family residential building at 555 Broderick St in Park North, built in 1927 and currently owned by the Nelson/noyon Living Trust, has experienced several concerning issues in recent years. Most notably, in early 2024, there have been two significant complaints regarding plumbing and mold issues, including reports of water leaks at sinks and sewage odors affecting resident health. A serious safety concern was filed in December 2020, indicating that the soft-story property had not been added to the city's mandatory seismic retrofit program, potentially compromising structural safety. The building has a history of fire safety violations, particularly in July 2007 when multiple fire-related issues were identified and required correction. Additional maintenance problems were documented in 2009, including mold, damaged surfaces, and concerns about the central alarm system.

The building's maintenance record shows periodic inspections and some improvements over time, including past roofing work in 2000 and various street space permits. Recent 311 calls from 2023-2024 have addressed various issues including garbage and debris concerns, plumbing problems, and mold, suggesting ongoing maintenance challenges. Historical violations from 2009-2017 included problems with handrails, fire-proofing, and general dilapidation, though most of these were marked as "Not active" after correction. The property has undergone routine safety inspections, with some requiring follow-up to address identified issues, including a bed bug infestation in 2012 and multiple repair needs in 2009 related to interior surfaces and ventilation problems. While some historical concerns have been resolved, the recent plumbing and mold issues, along with the unaddressed soft-story retrofit status, indicate ongoing maintenance and safety concerns that continue to affect residents.

Risk rating

How 555 Broderick St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
