Initial analysis

The three-story, five-unit multi-family residential building at 1135-1139 Kearny St in Telegraph Hill, owned by the Crystal Fong Ng Living Trust, was constructed in 1906 and has undergone several significant improvements over the past decades. Most notably, the building completed a mandatory soft-story seismic upgrade in 2015 at a cost of $50,000, demonstrating compliance with city safety requirements. Recent renovations include two substantial kitchen remodeling projects in 2022 ($30,000) and 2023 ($43,763), both involving electrical upgrades, showing ongoing maintenance and improvement of unit amenities. The building has a documented history of addressing maintenance and safety issues, with the most serious historical violations occurring in 2002-2007, including sprinkler head replacements, smoke detector installations, and fire extinguisher maintenance, all of which were properly abated. A building fire incident and CO detector activation were recorded, but fortunately, there were no civilian injuries in either incident. The property regularly undergoes routine inspection and maintenance, with the last major work being the installation of new roofing in 1991.

Recent activity in the surrounding area has involved multiple reports of general cleaning needs, primarily related to loose garbage, particularly in late 2023 through early 2024. While these issues are external to the building itself, they represent ongoing maintenance challenges in the immediate vicinity. The building has maintained active compliance with housing codes and safety requirements, with no active violations currently on record. The property has demonstrated a pattern of proactive maintenance and upgrading systems, particularly in terms of seismic safety and unit modernization, while maintaining historical compliance with fire safety and building codes.

Risk rating

How 1135-1139 Kearny 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.
