Initial analysis

The two-unit multi-family residential building at 1800 48th Avenue in San Francisco's Outer Sunset neighborhood, owned by Nancy A Garcia 2006 Revoc L, was constructed in 1951 as a single-story flats and duplex structure. The building has undergone several window-related improvements, with multiple permits issued in the 1980s for window replacements, including a completed project in 2001 to replace five windows at a cost of $3,348. More recently, in April 2023, a water damage and mold complaint was filed with Housing Inspection Services, though this case is currently listed as not active. The property has experienced recurring water-related issues, as evidenced by multiple fire department responses for water problems and leaks between 2018 and 2023, though no civilian injuries were reported in any incidents.

The building's recent history shows significant concerns with exterior maintenance and environmental conditions. Between July 2023 and January 2025, there were multiple reports of garbage and debris on the property, including instances of hazardous waste, bagged garbage, and loose debris. Several graffiti incidents were reported, affecting both the public sidewalk and the mailbox. A notable noise complaint was filed in September 2024 and remains open as of the latest report. The property's maintenance issues extend to public infrastructure, with reports of a blocked sidewalk due to privately maintained vegetation in July 2024. While there have been various fire department responses to the building, including one cooking fire and several alarm/system activations, none resulted in injuries or substantial damage. The building's permit history shows attention to window maintenance and improvements, though some permits from the 1980s are listed as expired.

Risk rating

How 1800 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
