Initial analysis

The three-unit, three-story multi-family residential building at 476-480 Duboce Avenue in Hayes Valley, owned by Brigitte & Anglito Uson, has a construction history dating back to 1900. The property has undergone several significant maintenance and infrastructure upgrades, most recently completing a sewer line replacement from foundation to house trap in February 2024, which suggests active maintenance of essential systems. Previous improvements include the replacement of three console heaters in 2013 and various structural repairs in 2020 involving non-street visible siding boards at the back porches.

A notable cluster of violations was recorded in March 2009 related to fire safety, lead paint hazards, and structural issues, though all were abated by May 2009, demonstrating responsive management to regulatory requirements. The building has maintained compliance with safety measures since these violations were addressed. The property has experienced recurring issues with graffiti and street cleaning matters in the immediate vicinity, with several reports between 2022 and 2024, though these are external to the building itself. The most recent documented works, including the 2024 sewer line replacement, indicate ongoing commitment to building maintenance, while the resolution of past violations suggests improved building management practices.

Risk rating

How 476-480 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

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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 46.7%
Moderate concern 17.8%
Severe concern 35.5%
