Initial analysis

The property at 463-465 33rd Ave is a two-unit, two-story multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1924, this flats and duplex building is currently owned by Michael Tam and has undergone several notable modifications over the years. In 2001, a significant renovation was completed on the first floor, updating a playroom, guestroom, and bathroom at a cost of $20,000. Two earlier permits from 2000 and 1993 show attempts at kitchen cabinet replacement (though this permit expired) and reroofing work respectively, while a street space permit was issued in 2008 for a nominal cost of $1.

The most concerning recent issues involve the building's driveway access, with multiple parking enforcement calls between 2022 and 2025, including at least five cases of vehicles blocking the driveway from July 2022 through January 2025, with citations issued in several instances. There have also been some public infrastructure concerns in the vicinity, including a flooding incident on the street in October 2022 and a sewage backup incident in January 2022 that required attention from PUC Sewer Operations. Other documented incidents include an offensive graffiti case in November 2022 that was addressed by the SES Graffiti Crew, and a general service request to DPW in July 2022 that resulted in no conditions being found upon inspection. The building's documented history suggests regular maintenance has occurred over the years, though some permits have expired without record of completion.

Risk rating

How 463-465 33Rd 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.
