Initial analysis

The two-unit multi-family residential building at 1517 48th Avenue in the Outer Sunset neighborhood, owned by Anh Thi Gonzalez, was constructed in 1925 and features two stories with a flat & store classification. The building's maintenance history includes several significant updates, such as a window replacement and front-side stucco work completed in 1997, electrical meter relocation in 2003, and sidewalk repairs in 2004. Of particular concern is a building complaint filed in June 2021 regarding persistent electrical beeping sounds occurring every 60 seconds, which was described as high-pitched and worrying to both residents and neighbors; though this complaint was not marked as actively abated, there are no subsequent related complaints on file.

The property has experienced multiple parking-related issues in the vicinity between 2019 and 2021, with several reports of illegal parking and abandoned vehicles, particularly involving a burgundy Chevrolet 1500 truck that was the subject of multiple complaints between June 2019 and a confirmed tow in May 2021. While these parking violations occurred in the surrounding area, they appear to be independent of any building-related issues and were addressed through appropriate enforcement channels, with one vehicle being towed for being unsafe. The building's permit history shows regular maintenance and upgrades over the years, with no recent permits indicating any major structural or systems changes.

Risk rating

How 1517 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.
