Initial analysis

239-241 Duboce Avenue is a two-story, four-unit multi-family residential building located in the Mission Dolores neighborhood. Built in 1900, the property is currently owned by Riccardi Nita & Luna Layla. The building's maintenance history shows several significant events, with particular attention to 2023, when multiple plumbing works were completed, including gas supply installation and direct vent gas insert installations in 2021-2023. A notable tenant buyout occurred in July 2023, involving 2 tenants and totaling $35,000. The building faced serious issues in 2002, when multiple violations were documented, including problems with water pressure, interior surface maintenance, fire safety equipment, and security features; these violations were not resolved until June 2015. Earlier complaints in 1999 and 1997 indicated problems with heating systems and structural issues, though these were subsequently addressed. The most recent inspection in 2009 was routine and no new violations were found at that time. A fire safety inspection in 2019 noted blocked exits but found no merit to the complaint.

Recent activity at the property has primarily consisted of parking enforcement issues, with multiple citations issued between May and November 2024 for vehicles blocking driveways. There have been some concerns about debris and garbage around the property, with several incidents reported in 2024. While the building's major violations from 2002 were finally resolved in 2015, the property has experienced periodic maintenance issues over the years, as evidenced by the various repairs and installations documented through building permits. The most recent renovations in 2023 suggest active property maintenance by the current ownership, though the building's age and history indicate that ongoing maintenance should be expected.

Risk rating

How 239-241 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.

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.

Building age

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

12-Month severity forecast
No violation 42.0%
Moderate concern 14.8%
Severe concern 43.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
