Initial analysis

The two-story, four-unit multi-family residential building at 1445 48th Avenue in the Outer Sunset, owned by Bernadette A. Boyle, was constructed in 1958 and has undergone several significant maintenance and improvement projects over the years. The building has experienced persistent moisture-related issues, with multiple reports of mold and water damage between 2001 and 2016, most notably a serious problem in 2016 involving leaks from kitchen windows and insulation concerns affecting temperature control and soundproofing. The property has maintained its infrastructure through regular updates, including kitchen and bathroom renovations in 2005 (valued at $35,000), multiple roof replacements (1989, 1997), and deck repairs (1992, 1997). A routine inspection in 2019 is currently marked as active, suggesting ongoing monitoring of the building's condition.

The building's violation history is particularly concentrated in 2001, when multiple issues were documented including fire safety concerns (such as fire extinguisher maintenance and smoke detector functionality), lead paint hazards, and sanitation violations, all of which were subsequently abated by September 2001. Recent infrastructure maintenance includes sewer-related issues in 2022, with one incident involving a sewage backup and another involving waste removal. The building has experienced three documented fire incidents, though none resulted in civilian injuries and one was determined to be caused by excessive heat with no ignition. The property's location has seen typical urban issues in recent years, as evidenced by 311 calls regarding sidewalk parking, encampments in the vicinity (reported in 2021), and streetlight maintenance needs.

Risk rating

How 1445 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.
