Initial analysis

The two-unit residential building at 3633-3635 Irving Street in San Francisco's Outer Sunset district is a two-story flats and duplex structure built in 1946, currently owned by the Chu Family Trust. The building's maintenance record shows two significant historical permit changes: a completed reroofing project in 1990 and a now-expired permit from 1985 for shower repairs, suggesting some basic maintenance was performed in the past, though no major renovations or improvements have been documented in recent decades.

The property has generated several 311 calls over the past five years, with the most recent incident occurring in November 2024 regarding an abandoned vehicle. Other notable events include a construction-related sidewalk blockage in July 2023 that resulted in a verbal warning to the property owner regarding proper permitting for scaffolding, and a driveway blocking incident in January 2022 that was resolved through police intervention. The building's surroundings have experienced recurring issues with graffiti on street signs between 2018 and 2019, with three documented cases (three of which were not considered offensive) that were all resolved through the Department of Public Transportation's Sign Shop. While these incidents are primarily related to street-level issues rather than the building itself, they provide some context about the immediate neighborhood's maintenance and enforcement environment.

Risk rating

How 3633-3635 Irving 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.

Neighborhood percentile
