Initial analysis

The two-unit multi-family residential building at 1414-1416 48th Avenue in San Francisco's Outer Sunset district was constructed in 1946 and is currently owned by Gassuan Guillaume. The building underwent an electrical service upgrade in August 2009, which included the installation of a new overhead two-meter service with 125-amp feeders and panels, a significant infrastructure improvement completed successfully.

The property has experienced recurring issues with illegal parking, particularly involving vehicles blocking the sidewalk, with multiple incidents registered between December 2023 and March 2025, including three instances where citations were issued. In April 2023, the building faced a sewage infrastructure challenge with a back-up incident involving water flow from a manhole cover, though this was subsequently resolved by PUC Sewer Operations. Additional reports from 2023 included a case of an abandoned vehicle that was towed in April, and a general street cleaning issue involving loose garbage that was addressed by the Department of Public Works in January. While the building's recent history shows persistent issues with parking violations in the immediate vicinity, the major systems improvements from 2009 and the prompt resolution of reported infrastructure issues demonstrate ongoing maintenance and responsiveness to immediate concerns.

Risk rating

How 1414-1416 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
