AI summary

The 525 Stockton Street building, a 6-story, 31-unit multi-family residential property constructed in 1920, has experienced several significant maintenance and safety issues over the past few years. Most notably, there have been recurring concerns about the building's fire safety systems, with violations and complaints regarding blocked exits, extinguishers, alarm systems, and sprinkler/standpipe systems occurring between 2015 and 2024, though most were eventually corrected. In 2022, the elevator was reported out of service for a week, and in October 2022, there was an issue with a large planter box hanging from a top-level window. The building has a documented history of boiler-related problems, including a 2019 complaint about an expired operation permit and combustion air issues, along with multiple violations from 2007-2019 regarding fire proofing, self-closing doors, and window repairs. Between 2018 and 2024, there have been various routine inspections and maintenance requests requiring attention to building systems and interior conditions. Recent municipal records from 2023-2024 primarily show minor issues related to street cleaning and garbage collection around the property. The building has experienced several incidents requiring fire department response, including smoke detector activations, a cooking fire, and elevator rescues, though none resulted in civilian injuries. A utility excavation issue was noted in September 2023, requiring permit restoration work in the travel lane.

Risk rating

How 525 Stockton 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.

Neighborhood percentile
29th percentile

Out of 448 buildings in this neighborhood, 318 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 12.4%
Moderate concern 78.0%
Severe concern 9.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
