Initial analysis

The 7-unit, 3-story multi-family residential building at 1440 Jones Street in Nob Hill, owned by Bay Properties Inc., was constructed in 1910 and has experienced several significant maintenance and safety-related events over the years. Most notably, between 2016 and 2022, the building faced multiple compliance issues, including boiler permit violations, stair repairs, and various safety concerns such as inadequate auxiliary lighting, hot water heater problems, and the need for carbon monoxide/smoke alarm inspection confirmations. In 2022, the building underwent a $30,000 deck replacement project, while earlier improvements included a water heater and hydronic boiler replacement in 2016, addressing some of the building's mechanical systems concerns.

The property has a history of maintenance issues requiring attention, with documented complaints about heating problems dating back to the 1990s, including no heat and insufficient heat complaints in 1994-1996. In 2012, there was a complaint regarding peeling and mold-ridden exterior paint. The building had several routine inspections in the 2000s, revealing various safety violations that were subsequently addressed. More recent history shows primarily external issues, with multiple reports of sidewalk parking violations (2023-2024) and a missing side sewer vent cover in 2022. A fire-related exit maintenance issue was reported and corrected in late 2020. The property maintains its original 1910 building structure while undergoing periodic repairs and updates to address code compliance and maintenance requirements, with the most recent significant work being the 2022 deck replacement.

Risk rating

How 1440 Jones 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.
