Initial analysis

The three-unit residential building at 1808 46th Avenue in San Francisco's Outer Sunset neighborhood, owned by Diana Mayling Liu, was constructed in 1990 and has experienced several significant events throughout its history. The building underwent multiple fire safety-related issues in 2002, including problems with fire extinguishers, smoke detectors, egress obstructions, and combustible materials in the garage area, though all violations were abated by February 2002. Fire alarm system concerns were notably problematic in 2008, with multiple complaints (six recorded incidents) regarding the alarm system, all of which were ultimately corrected. The building has received regular maintenance, including a reroofing project in 2014 ($9,000) and window replacements in Unit 3 in 2008 ($2,500).

Recent developments (2024-2025) have primarily involved external issues rather than internal building concerns, including multiple encampment reports, noise complaints, and incidents of garbage and debris around the property - these external situations generally reflect neighborhood conditions rather than building management issues. The building's fire incident history shows relatively minor occurrences, including alarm malfunctions, a water leak, and a smoke detector activation, with no civilian injuries recorded. While the building has experienced various safety-related issues in the past, particularly in its early years, there have been no recent building violations or complaints regarding internal safety systems since 2015.

Risk rating

How 1808 46Th 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
38th percentile

Out of 632 buildings in this neighborhood, 392 are predicted to be safer.
