Initial analysis

440 Bartlett Street is a 2-story, 4-unit multi-family residential building constructed in 1910 and currently owned by Dionicio & Leticia Lopez. The property has undergone several significant renovations, including a major electrical re-wiring project in 2003 that included installation of comprehensive electrical infrastructure including 20 lights, 20 switches, 40 receptacles, 30 circuits, 5 panels/switchboards, and a 200A service entrance. A series of building violations were filed in August 2006, addressing multiple maintenance issues including interior surface problems, plumbing and electrical concerns, and fire safety matters. These violations were all resolved by August 2007. More recent concerns have emerged, including a mold issue and exposed electrical wires in the laundry area reported in September 2023, and a broken building sewer complaint from December 2022 that remains active as of October 2023. The building has experienced recurring sewer issues, with multiple sewage backup incidents reported between 2021-2022, and several street cleaning and hazardous materials reports in the vicinity of the property. A routine inspection in 2015 was conducted and completed, while a 2001 inspection also showed no significant ongoing issues. The property has had some recent maintenance challenges, particularly regarding sewer infrastructure, which appears to be an ongoing concern.

Risk rating

How 440 Bartlett 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.
