Initial analysis

The two-unit residential building at 1419-1421 19th Avenue in San Francisco's Central Sunset neighborhood, owned by the Kent & Minling Ruan Trust, is a two-story flats/duplex structure constructed in 1946. The building's documented history shows several maintenance and improvement projects from the 1980s, including a horizontal rear addition, front stucco work, and installation of aluminum windows, all properly completed. More recently, in 2015, minor sidewalk repairs were performed. A fire complaint was filed in December 2016 for operating without a permit, but this issue was promptly resolved within three weeks.

The immediate vicinity of the property has experienced various street-level issues in recent years, particularly during 2023-2024, with multiple reports of graffiti affecting public transit infrastructure and city receptacles, though these were not directly related to the building itself. Other external incidents included medical waste (needles) removal, garbage and debris issues, and a pavement defect, all of which were resolved by city services. The neighborhood's ongoing maintenance needs have been consistently addressed by city departments, with all reported cases being closed and resolved, though some required multiple reports to achieve resolution. The building's permit and complaint history suggests regular maintenance has been performed when required, with no significant structural or safety issues reported since the 1980s renovations and 2016 permit violation.

Risk rating

How 1419-1421 19Th 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
