Initial analysis

The 3-unit, 2-story multi-family residential building at 3629-3633 Cabrillo Street in San Francisco's Outer Richmond neighborhood was built in 1949 and is currently owned by Nathaniel P. Robinson. The property has undergone several significant improvements over the past 25 years, including a comprehensive window replacement project in 1997-1999 involving multiple installations of vinyl windows (totaling 27 windows), the addition of an elevator shaft and installation of an elevator in 1999, and a 2015 electrical upgrade that included a new 200-amp overhead service with four meters and panels. Recent plumbing work in 2015 involved installing a gas line for the basement unit and was followed by the replacement of a water heater in 2008. The building experienced a series of violations in January 2008 during a routine apartment housing inspection, which identified several safety and maintenance issues including requirements for fire extinguishers, plumbing permits, gas shutoff tools, and repairs to a side exit door; however, all these violations were resolved by May 21, 2008.

The property's maintenance history shows attention to major systems and infrastructure, with earlier work including a complete reroofing in 1992. While there have been various 311 calls related to the property's vicinity, these are mostly concerning street-related issues (such as parking and streetlights) rather than building-specific problems. The most recent building-related interventions appear to be the 2015 electrical upgrade and plumbing improvements, suggesting that while the building is maintained, major systems have been previously updated to modern standards. The property has successfully addressed all identified violations and complaints, with no active issues on record as of October 2023.

Risk rating

How 3629-3633 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

Out of 1040 buildings in this neighborhood, 759 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 size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 53.2%
Moderate concern 23.7%
Severe concern 23.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
