Initial analysis

The property at 709 San Bruno Ave in Potrero Hill is a two-unit, two-story multi-family residential building constructed in 1904, currently owned by Frank Karl A & Carrara Fran. The building has undergone several significant renovations over the years, with the most recent substantial work occurring in 2013 involving kitchen cabinet replacements and bathroom remodeling, valued at $30,000. This followed two earlier renovation attempts in 1986-1987, which ultimately expired without completion. A final inspection for previously approved work was successfully completed in 2022, representing the most recent permitted activity on record.

The building's history reveals recurring water-related infrastructure issues, particularly in the early 2010s, with multiple complaints regarding water damage and drainage problems affecting both this property and the neighboring unit at 707 San Bruno Ave. These complaints, filed in 2011 and 2012, documented concerns about kitchen leaks, standing water between the buildings, and foundation damage. While these specific plumbing issues have not reappeared in recent years, they represent a notable pattern of water management challenges for the property. Other documented events include construction noise complaints in 2013, perceptions of waste management irregularities in 2017-2018, and several reports of abandoned vehicles near the property, though these last incidents were more related to street conditions than the building itself. The property's most recent inspection-related activity occurred in 2022, with no documented building code violations or safety issues since that time, suggesting improved compliance with building maintenance requirements.

Risk rating

How 709 San Bruno 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 726 buildings in this neighborhood, 182 are predicted to be safer.
