Initial analysis

The property at 111-113 Putnam Street in Bernal Heights is a one-story, two-unit multi-family residential building classified as a Flats & Duplex, constructed in 1959 and currently owned by William Kuon-chung Ko. The building has undergone several significant maintenance improvements over the past decade, most notably a complete siding replacement in 2022 with new James Hardie lap siding valued at $25,275, and a sewer and house trap replacement in 2012. The building's maintenance history reveals some past issues that have been addressed, including a cluster of violations in 2001 related to window hardware, weatherproofing, damaged walls, and lead paint concerns, all of which were officially abated by December 10, 2001.

Recent records indicate some ongoing infrastructure concerns in the immediate vicinity, with two sidewalk/curb defect reports filed in July 2023 (one of which remains open), and previous issues related to abandoned vehicles and parking enforcement in the area. Historical permits from 1989 show attempts to replace windows and reroof the building, though these permits were either cancelled or expired. The property's external needs have been consistently addressed over time, as demonstrated by the 2022 siding upgrade and the completed sewer work, suggesting ongoing maintenance attention by the owner. The most recent building improvement, focusing on exterior siding, indicates active property upkeep, though the presence of recent sidewalk issues near the property might be worth monitoring.

Risk rating

How 111-113 Putnam 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.
