Initial analysis

The two-unit residential building at 4430 Cabrillo Street in San Francisco's Outer Richmond neighborhood is a two-story structure built in 1915, currently owned by Charles Maddox III. The building has undergone several significant improvements over the past two decades, with the most substantial recent work occurring in 2014 when a non-structural renovation was completed, including a new master bathroom, electrical repairs, and replacement of seven windows at a cost of $25,000. Other notable improvements include the replacement of two furnaces in 2013, kitchen and bathroom remodeling in 2001, repair of dry rot around the garage door in 2001, and various window replacements.

The property has experienced regular maintenance issues typical for its age, including a 2016 sewage backup incident that was resolved by PUC Sewer Operations. The building has been subjects to some environmental and safety concerns, with a hazardous materials report (though not directly related to the building itself) regarding liquids on the street in December 2020, and a non-offensive graffiti incident in 2016 that was administratively closed by Public Works. Recent years have seen recurring issues primarily related to parking violations in the surrounding area, with multiple citations issued for driveway blocking between 2018 and 2023, and occasional street cleaning needs, including reports of loose garbage. The property's maintenance history suggests regular upkeep, though prospective tenants should note the building's age and the associated typical maintenance requirements.

Risk rating

How 4430 Cabrillo 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
37th percentile

Out of 1040 buildings in this neighborhood, 655 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.

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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 71.6%
Moderate concern 21.6%
Severe concern 6.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
