Initial analysis

The three-story multi-family residential building at 3640-3646 Balboa Street, located in San Francisco's Outer Richmond neighborhood, contains three units and was constructed in 1925 with a ground floor commercial space. The property underwent significant renovations in 2004-2008, including the addition of two new residential units above the existing structure at a cost of $621,374, and the conversion of mezzanine storage on the ground floor into habitable space combining with unit #1. The building's systems received substantial upgrades during this period, with electrical work including the installation of a new 400-amp service, multiple circuits, and comprehensive lighting and outlet installations, as well as plumbing improvements including bathroom and laundry facilities on the second floor.

More recent history shows maintenance activity with the replacement of a gas water heater in October 2022, and there was a fire code violation noted in November 2020, which was promptly addressed on the same day. Of particular note, there has been a recent pattern of municipal service calls regarding waste management, with ten reports of overflowing city garbage cans between January 5-14, 2025, all of which were resolved. These permits, violations, and service calls provide a comprehensive view of the building's history, showing significant investment in modernization and infrastructure upgrades during the 2000s, with relatively minimal maintenance issues in recent years except for the noted waste management concerns.

Risk rating

How 3640-3646 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.
