Initial analysis

The two-unit residential building at 1513 48th Avenue in San Francisco's Outer Sunset neighborhood is a single-story flats and duplex structure built in 1926, currently owned by the Louise Moy Fong-wang Living Trust. The most significant incident on record occurred in June 2021, when multiple complaints were filed regarding persistent electrical beeping sounds in and around the building, reported at both 10:47 AM and 11:32 AM on June 17, 2021. These complaints indicated the sounds occurred every 60 seconds and were concerning to both residents and nearby neighbors, though no resolution status was recorded in the system.

More recently, the property has experienced typical urban neighborhood issues, including a series of reports in 2023 and 2024 related to street conditions and abandoned vehicles. These included three notable incidents: a closed case regarding abandoned electronics in July 2024, human or animal waste in January 2023, and a missing street cleaning sign in March 2023. Earlier records from 2020-2021 documented several abandoned vehicle reports and parking violations in the vicinity, with most cases being resolved when vehicles were found to be complying with laws upon inspection. While these issues reflect typical street-level concerns for the neighborhood, they do not directly indicate any specific problems with the building itself.

Risk rating

How 1513 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.

Neighborhood percentile
