Initial analysis

The two-unit residential building at 639 33rd Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1925, currently owned by the Karen Nagareda Revoc Trust. The property has undergone several significant maintenance and repair projects over the past decade, including a 2019 dry rot repair of landing and stairs in the south-facing lightwell ($1,200), a 2012 reroofing project ($9,970), and a plumbing issue in 2022 involving the replacement of a broken house trap at the city sidewalk, though this permit has since expired. A notable safety concern was recorded in February 2023 and January 2024 regarding tree root damage to the sidewalk, which remains listed as an open issue.

The most pressing recent developments at the property involve recurring issues with driveway access, with multiple parking enforcement calls recorded throughout 2024. There were eight documented cases of blocked driveways between August and October 2024, with most cases being addressed through citations or other enforcement actions, though one case from September was listed as "Unable to Locate" and another from August was deemed invalid due to incomplete reporting information. The building's record shows one fire incident, though it was classified as a false alarm with no civilian injuries reported.

Risk rating

How 639 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.

Neighborhood percentile

Out of 1040 buildings in this neighborhood, 499 are predicted to be safer.
