Initial analysis

40 Wentworth Place is a three-story, 9-unit multi-family residential building constructed in 1963, currently owned by the Chong Sen Benevolent Association. The building has a documented history of fire safety concerns, with multiple violations and complaints regarding alarm systems, sprinkler systems, extinguishers, and electrical systems between 2021 and 2024, though most issues have been resolved promptly. Recent maintenance records show attention to fire safety systems, with the most recent fire complaints regarding sprinkler/standpipe systems and alarm systems being corrected in October 2024. The building underwent several routine safety inspections between 1999 and 2015, during which various violations were identified, including egress obstructions, fire escape maintenance issues, and security requirements, though these were generally abated within a few months.

Recent 311 calls from 2023-2024 indicate ongoing concerns with garbage, debris, and occasional graffiti on the property, as well as a water complaint in September 2024. The building's maintenance records show a pattern of fire safety system violations, particularly regarding alarms and sprinklers, with documented cases of both "Condition Corrected" and "No Merit" findings by inspectors. The property has been consistent in addressing violations once cited, with most being classified as "abated" following correction. The building's historical permit records show an attempt in 1998 to relocate the benevolent association's space in the basement, though these permits are currently listed as expired. While the building has experienced recurring issues with fire safety systems, recent records suggest ongoing maintenance and prompt resolution of safety concerns, though the frequency of related violations raises some operational safety pattern concerns.

Risk rating

How 40 Wentworth Pl'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
34th percentile

Out of 145 buildings in this neighborhood, 96 are predicted to be safer.

Building size

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

Number of units

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

Construction type (C)

The building's construction type on file, which affects its maintenance risk profile.

12-Month severity forecast
No violation 13.4%
Moderate concern 70.7%
Severe concern 15.8%
