Initial analysis

The 8-unit, 2-story multi-family residential building at 157 Duboce Avenue in Mission Dolores, owned by the Kai-man Tsui 2018 Revocable Trust, has undergone several significant maintenance and safety improvements since its construction in 1924. The building completed its mandatory soft-story seismic retrofit in 2014 (Tier 3), and most recently underwent reroofing work in 2024 at a cost of $22,000. Between 2000 and 2006, the property experienced various maintenance issues, including multiple violations in 2006 related to water damage, stairs, electrical systems, lead hazards, and security requirements, all of which were abated by August 2006. During this period, there were also significant repairs to address dry rot in staircases, window replacements, and various interior improvements including kitchen and bathroom renovations.

The building has experienced several safety-related incidents recorded by the fire department, primarily involving false alarms and gas leak responses, though fortunately none resulted in civilian injuries. A notable cluster of maintenance and safety concerns emerged in 2006, including complaints about lighting, stairs, water damage, and security features, all of which were addressed within a few months. The property has maintained compliance with major housing and safety requirements, including the completion of the soft-story retrofit program and various electrical improvements. Recent years have shown relatively few internal maintenance issues, with 311 calls primarily relating to external matters such as parking enforcement and street cleaning. The most recent building improvements, including the 2024 reroofing project, suggest ongoing investment in maintaining the property.

Risk rating

How 157 Duboce 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
30th percentile

Out of 799 buildings in this neighborhood, 559 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast

Moderate concern 18.1%
Severe concern 38.6%
