Initial analysis

This two-story, four-unit multi-family residential building located at 740 Bacon Street in the Portola neighborhood was built in 1963 and is currently owned by Louie Judy O. The building has a documented history of maintenance and safety issues, with the most significant cluster of violations occurring in 2011, when multiple problems were identified including mold/mildew on walls, damaged walls around windows, and concerns about lead-based paint hazards. These violations were officially abated by May 2011. Prior to this, in 2006, there were fire safety concerns including missing fire extinguishers and the presence of a BBQ grill on the front roof, while 2008 violations addressed fire proofing requirements and combustible storage.

The building's maintenance history includes several repairs and improvements, such as a reroofing project completed in 2004 at a cost of $3,000. Earlier issues from the 1980s include dryrot repairs in various areas. More recent activity around the property has been documented through multiple 311 calls in 2024 and 2023, primarily relating to street cleaning and sidewalk maintenance issues including reports of loose garbage, debris, and furniture. The building has undergone regular routine inspections, with records dating back to 1996, showing consistent oversight by housing inspection services. While many past violations have been resolved, the pattern of maintenance issues and the age of the building suggest ongoing attention to upkeep may be required.

Risk rating

How 740 Bacon St'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
24th percentile

Out of 255 buildings in this neighborhood, 194 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 location

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

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 34.5%
Moderate concern 29.4%
Severe concern 36.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
