Initial analysis

The property at 1521-1523 48th Ave in San Francisco's Outer Sunset district appears to be a multi-family residential building that has undergone several significant modifications and faced various maintenance challenges over the years. Most notably, in 2006-2007, substantial interior improvements were made, including the conversion of an unimproved basement into two bedrooms and a laundry area with bathroom, along with the installation of electrical fixtures including 15 lights, 25 receptacles, and 10 switches. However, there have been persistent concerns about the building's electrical systems, with a troubling electrical beeping sound reported in June 2021 that reportedly continued to affect residents and neighbors.

The building has experienced several safety-related issues, most notably in 2002 when violations were recorded regarding fire safety equipment and smoke detectors, though these were promptly addressed within a month. A more recent fire safety concern was documented in 2015 regarding blocked exits, which was corrected by October 2015. The property has undergone various permit processes, including street space permits and sidewalk repairs, and has had multiple plumbing and electrical work completed. Recent records from 2023-2025 show numerous parking-related complaints in the vicinity, with multiple instances of driveway blocking resulting in citations, though these issues are external to the building itself. The building's maintenance history shows a pattern of addressing interior improvements and responding to safety concerns, though the 2021 electrical issue appears to have been particularly disruptive.

Risk rating

How 1521-1523 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.
