Initial analysis

The three-unit residential building at 933-939 Jones Street in Downtown, owned by the Tom Randall Estate, has undergone significant safety upgrades and improvements over the past few years. Most notably, between 2022 and 2023, the building received comprehensive fire safety enhancements, including the installation of a new automatic fire alarm system, fire sprinkler system with underground service, and new electrical infrastructure with 400-amp service throughout all units. These improvements followed earlier work in 2022 to address insulation and evaluate seismic conditions. The building has a history of addressing maintenance issues, with records showing repairs to stairs and interior finishes in 2007, window panels in 2003, and various unit upgrades including kitchen and bathroom renovations.

Recent permit activity indicates ongoing attention to building safety and infrastructure, including plumbing work for radiant heating and final inspections for various systems. While the building has experienced some violations in the past (2003-2007), these were generally resolved promptly, and recent history shows no active building violations. The property has two recorded fire alarm incidents, neither resulting in injuries or confirmed fires. Recent 311 calls primarily relate to external maintenance issues around the property, such as garbage debris and sidewalk cleaning, suggesting ongoing urban maintenance challenges in the vicinity.

Risk rating

How 933-939 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.
