Initial analysis

The 7-unit, 4-story multi-family residential building at 1549 Jones Street in Nob Hill, owned by Kwan Anson, was constructed in 1913 and has experienced several noteworthy maintenance and regulatory events. Most recently, in late 2022, the building underwent a significant $14,500 reroofing project. The building has a documented history of boiler-related issues, with the most recent violation in December 2020 regarding an unpermitted boiler operation that was ultimately abated in February 2021. A pattern of heating system challenges is evident, including a no-heat complaint in July 2012 affecting multiple apartments, and an unauthorized boiler operation violation in 2015, though these issues appear to have been resolved.

The property has undergone several routine housing inspections over the years, with one particularly notable period of violations in 2000 that resulted in multiple citations, including repairs needed for stairs, damaged walls, window components, and various safety requirements. While these violations were addressed, the building has continued to show periodic maintenance needs, including a significant stairs repair project in 2000 and stairway-related repairs in 2005. Recent property management responses have been documented through numerous 311 calls and service requests, primarily related to exterior maintenance issues such as garbage and debris removal, though these appear to be more neighborhood-related concerns rather than building-specific problems. The building's fire incident record shows a single false alarm or false call with no civilian injuries reported.

Risk rating

How 1549 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
