Initial analysis

The three-story, four-unit multi-family residential building at 131-135 Cortland Ave in Bernal Heights, owned by Kenneth C & Janet M Bollier, has a mixed maintenance history dating back to its 1900 construction. The property experienced several significant infrastructure issues between 2007-2008, including a sewage leak affecting neighboring units, which was documented in a November 2007 violation and subsequently repaired in December 2007. A 2008 inspection revealed unauthorized roofing work on the rear garage structure that required correction under San Francisco Building Code, and the same year, stair repairs were needed at the rear of the building, leading to several housing-related violations that were eventually abated.

More recent records (2022-2025) show ongoing maintenance challenges in the immediate vicinity of the property, though these are not direct building issues. These include sidewalk cleaning needs, graffiti incidents, and waste management concerns, with the most recent complaints relating to a missed toter pickup and graffiti on sidewalk structure in 2024. A notable safety incident was documented as a carbon monoxide situation (424) with no civilian injuries, though the date and specific location details are not provided in the records. The building's maintenance history suggests an active response to structural issues during 2007-2008, with multiple repair projects completed, including reroofing work and sewer line repairs, though some violations were initially issued requiring correction.

Risk rating

How 131-135 Cortland Ave'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

Out of 1276 buildings in this neighborhood, 829 are predicted to be safer.

Number of units
