Initial analysis

The two-family residential building at 139-141 Bernard Street in Nob Hill, owned by Larry & Karen Lee Ng 2018 T, is a two-story structure built in 1970. The property has undergone several significant improvements in recent years, with the most notable being comprehensive kitchen and bathroom renovations completed in late 2020, including new appliances, cabinets, electrical systems, and plumbing fixtures, with a total improvement cost of $36,000. This renovation work was properly permitted and included installation of modern electrical systems and new plumbing fixtures in both units. In 2015, the building received important infrastructure upgrades including the replacement of two furnaces, and in 2014, vinyl siding was added to the back wall of the building.

A notable building complaint was filed in November 2022 regarding unauthorized construction work, specifically concerning plywood covering common area staircase windows and the apparent construction of an illegal structure in what was originally a light well. This complaint was addressed and abated by December 2022. The building's maintenance history shows regular upkeep and improvements, though there have been multiple reports of abandoned vehicles on or near the property between 2012 and 2023. The most recent service request related to the property was in September 2023 for general street cleaning. Temporary parking sign requests for moving purposes were successfully completed in late 2015. The property's recent history suggests active management and maintenance, with all major improvements being properly permitted and completed, though there was one instance of unauthorized work that was subsequently addressed.

Risk rating

How 139-141 Bernard 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.
