Initial analysis

The property at 1408-1412 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1946, currently owned by Alex Yi Jun Tong. The building has undergone several significant renovations and maintenance work over the years, with the most recent major issue being a lead paint violation filed in March 2023 that required attention to interior surfaces and resulted in multiple notices for non-compliance, though these were successfully abated by September 2023. The building's maintenance history includes three major roofing projects (2006, 2017, and most recently in 2018 with a service pipe relocation), substantial first-floor renovations in 2009 adding bedrooms and bathrooms, and various interior improvements including a kitchen remodel and stucco replacement work in 2005.

The property has faced recurring issues with sidewalk parking violations, with multiple enforcement calls between 2020 and 2024, though these were mostly unresolved as officers were unable to locate the vehicles at the time of response. While not directly related to the building's condition, these parking issues represent an ongoing challenge in the immediate vicinity. The building's permit history suggests regular maintenance and upgrading of facilities, with appropriate attention paid to major systems including electrical service, plumbing fixtures, and safety concerns such as lead paint remediation.

Risk rating

How 1408-1412 48Th 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.
