AI summary

The property at 4634-4636 Cabrillo Street is a two-unit, two-story residential building located in San Francisco's Outer Richmond neighborhood. Built in 1941, this flats/duplex structure has undergone several significant maintenance and improvement projects over the years. Most recently, in June 2024, a complete main sewer line replacement was completed, demonstrating ongoing infrastructure maintenance. Previous major works include a $21,000 reroofing project completed in 2014, kitchen repairs in 2010 including countertop and cabinet work, electrical upgrades in 2009 involving meter socket replacements, and a vertical and horizontal addition completed in 1991. Notably, there was a significant housing complaint filed in 1997 regarding lack of heat and unauthorized entry by the landlord, though this issue was officially resolved by late 1997.

Risk rating

How 4634-4636 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.
