Initial analysis

The three-unit, two-story multi-family residential building at 1505-1507 48th Avenue in San Francisco's Outer Sunset neighborhood was constructed in 1948 and is currently owned by the James J Coughlan Revocable Living Trust. The building's maintenance history shows attention to critical infrastructure, with a reroofing project completed in 1997 and remediation of dry rot issues addressed in 1993 following a pest control report.

The property has an extensive record of external maintenance issues in recent months, with numerous 311 calls primarily related to garbage and debris on the surrounding streets between July and December 2024. These reports include incidents involving hazardous waste, abandoned electronics, and illegal parking concerns, with varying outcomes including resolved cases and ongoing investigations. The building's safety systems have experienced at least two fire department responses—one for a malfunctioning smoke detector and another for a false alarm—though importantly, no civilian injuries were reported in either incident. The property's age and infrastructure history, combined with the recent pattern of external maintenance issues, suggest ongoing challenges with neighborhood cleanliness and property upkeep.

Risk rating

How 1505-1507 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.
