Initial analysis

The two-unit residential building at 1518 19th Avenue in the Inner Sunset, owned by Kenny Kiet Mao and Xua Truong, was constructed in 1931 and has undergone several significant changes and faced various compliance issues over the years. Most notably, there was a serious situation in 2005 when an illegal unit was created in the garage area, which resulted in a kitchen fire and multiple code enforcement complaints (complaint #200561177) that remain active. This unauthorized modification included converting a "U-1" occupancy space into an office for "B" occupancy business use, replacing the garage door with a tradesman door, and creating a separate third living unit. The building underwent a vertical addition in 1989, and more recently, in 2024, there is an open permit for exploratory foundation work related to its interaction with the neighboring property at 1500 19th Avenue.

The property has a history of compliance attempts, including a 2015 unit legalization effort that was filed to address various code infractions, and a 2005 permit to remove the illegal office and restore the garage to its original configuration, though this permit expired. The building has also seen various maintenance and improvement work, including termite repair in 1985, installation of aluminum windows in 1989, and several electrical upgrades. Recent activity at the property has primarily involved external maintenance issues, with multiple parking enforcement calls for blocked driveways and reports of garbage and debris on the street. While these parking and sanitation issues have been generally resolved, they indicate ongoing challenges with property access and neighborhood maintenance. A concerning safety issue was addressed in 2004 when it was reported that the fire escape stairs had been removed and replaced with a wooden gate, though this complaint is no longer active.

Risk rating

How 1518 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

Out of 1493 buildings in this neighborhood, 388 are predicted to be safer.
