Initial analysis

The three-story multi-family residential building at 451-455 Duboce Avenue, owned by Robert D. Sr & Cather Gallot, was constructed in 1900 and contains three units. The building's maintenance history shows recurring attention to dry rot issues, particularly in the back stairs, with multiple repairs documented between 1992 and 1995. More recently, the building underwent mechanical upgrades in 2021, including the installation of a new gas furnace and associated ventilation work, with proper permits obtained and completed.

The property has faced several building violations over the years, with the most recent active complaints dating from May 2016, primarily related to interior surfaces including paint conditions, fire safety features, and building weatherproofing. Historical violations from 2000 indicated lead paint hazards, though these were marked as abated in 2001. The building's exterior maintenance has been a recurring focus, with multiple inspection records noting issues such as peeling paint. Recent 311 calls from late 2024 have primarily concerned parking enforcement matters, with multiple citations issued for driveway blocking, though these are external to the building's condition and maintenance history.

Risk rating

How 451-455 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 48.3%
Moderate concern 19.1%
Severe concern 32.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
