Initial analysis

The two-unit residential building at 3139 Balboa Street in San Francisco's Outer Richmond neighborhood, owned by the Cavallero Family Trust, is a two-story flats/duplex structure constructed in 1955. The property has undergone several significant maintenance and improvement projects over the past two decades, including a comprehensive reroofing in 2002 costing $11,600, followed by more substantial repairs in 2011 when approximately 15% of the front woodwork was replaced due to dry rot, including full wire/lath and stucco work at a cost of $8,000. A furnace replacement was undertaken in 2018, though records show this permit expired. The building experienced a minor maintenance issue in April 2022 with illegal postings that required removal by the SES Graffiti Crew.

Of particular note is a tenant buyout that has been recorded for the property, dated August 16, 2024, with an amount of $79,916 for one tenant. This pending buyout suggests potential changes to the building's occupancy status, though as of now, the property retains its two-unit designation. The building's maintenance history shows regular upkeep and necessary repairs have been addressed over time, with no major safety concerns or violations recorded in recent years. The most significant structural works appear to have been completed over a decade ago, with more recent permits focusing on individual system replacements rather than major renovations.

Risk rating

How 3139 Balboa 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.
