Initial analysis

The 3-story, 9-unit apartment building at 1447 Jones Street in Nob Hill, owned by Stephen H Silvani Living Trust, was constructed in 1924 and has undergone several significant maintenance and safety upgrades over the years. Most notably, the building completed a mandatory soft-story retrofit in 2017 (Tier 3) that included new ply shear walls and foundations at a cost of $60,000, demonstrating compliance with seismic safety requirements. The building has faced recurring maintenance challenges, particularly in recent years, with multiple tenant complaints between 2019-2022 reporting issues such as inadequate heating, water intrusions, mold growth, and pest infestations. These problems culminated in serious concerns during 2021, with complaints about extreme water damage, leaky roofs, and mold affecting multiple units, particularly on the top floor.

The property has a documented history of building code violations, most notably in 2008 when multiple issues were identified regarding fire safety systems, handrails, and electrical illumination in common areas, though these were all abated by June 2009. More recent fire safety inspections revealed violations in 2018 (sprinkler/standpipe systems and alarm systems) and 2023 (multiple fire code violations), though the 2023 violation from August was issued the same day. The building's safety systems have generally been maintained, with records showing prompt correction of many fire system violations and the installation of motion lights in 2018. Recent plumbing improvements include a boiler and tank replacement in 2017, though this permit has since expired. While the building has made some progress on major safety concerns like seismic retrofitting, the pattern of recurring maintenance issues and resident complaints over the past three years raises ongoing concerns about the property's maintenance and management practices.

Risk rating

How 1447 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.

Neighborhood percentile
3th percentile

Out of 1125 buildings in this neighborhood, 1091 are predicted to be safer.
