Initial analysis

The 13-unit, 4-story apartment building at 1630 Jones Street in Nob Hill, owned by Edward C K & Marina C Y You, was constructed in 1929 and has undergone numerous significant upgrades over the years. Most recently, in December 2024, the building initiated a $35,000 upgrade to its fire alarm system to comply with SFFC requirements, including the installation of 75 dB alarms in all sleeping areas. This project followed an earlier electrical permit in December 2024 for fire alarm system modifications and device updates. The building has experienced several fire safety-related incidents and violations, including sprinkler system issues in 2022 (requiring a subsequent violation correction), 2018, and 2016, though none resulted in civilian injuries. Historical improvements include a comprehensive window replacement project in the early 1990s, bathroom and kitchen renovations in 2011, and mechanical upgrades including a boiler replacement in 2012.

The building has undergone regular routine safety inspections by Housing Inspection Services, with the most recent occurring in December 2019. A cluster of fire safety violations was recorded in April 2000, including issues with gas meter instructions, combustible storage, and smoke enclosure door closers, though all were abated by May 2000. The property has maintained active compliance with housing safety standards, as evidenced by routine inspections and prompt attention to violations. Recent 311 calls (2022-2024) have primarily concerned street cleaning and debris issues outside the building, rather than internal maintenance or safety concerns. The building's maintenance history demonstrates ongoing investment in safety systems and infrastructure, with particular attention paid to fire safety compliance and regular updates to essential building systems.

Risk rating

How 1630 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
