Initial analysis

The two-unit residential building at 736-738 46th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1964, currently owned by Sue Hsia. The building's maintenance record shows significant attention to exterior upkeep, with notable repairs including addressed rotted wall sheathing and stucco work at the front of the building in 1995, and an electrical system upgrade to a 100-amp service completed in 2006. However, the property has experienced recurring infrastructure challenges, particularly with sewer systems, as evidenced by five documented sewage backup incidents between January 2020 and October 2021, with at least one incident involving grease-related issues. Recent municipal service requests indicate ongoing surface maintenance concerns, with an open sidewalk defect reported in November 2024 and a historical pavement defect involving a 3x3 ft pothole near the connection to main sewer line reported in 2019. The property has experienced several parking-related issues in recent years, including two instances of sidewalk parking (2020 and 2022) and driveway blocking (2024), though enforcement officers were typically unable to validate the violations. While the building has undergone some necessary improvements over the decades, the recurring sewer issues and recent sidewalk concerns could impact resident experience.

Risk rating

How 736-738 46Th 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
