Initial analysis

307 Capp Street is a three-story, 12-unit multi-family residential building built in 1908 and owned by Paul and Carol Wong. The building has undergone several significant improvements over the years, most notably completing a mandatory soft-story seismic retrofit in 2015 at a cost of $120,000, which brought the building into compliance with San Francisco's seismic safety requirements. The property has faced multiple health and safety challenges, particularly between 2015-2016, when it experienced rodent infestations, plumbing issues, electrical problems, and interior surface deterioration, including mold and mildew. These violations were eventually abated through various repairs, including plumbing upgrades, electrical improvements, and general maintenance work.

More recent concerns include recurring fire safety issues, with violations recorded in 2023 and 2024 regarding fire extinguisher maintenance and alarm system upkeep, though these were marked as "abated." The building has also experienced periodic water-related issues, with complaints about leaks and deteriorated walls reported in 2017 and 2018. The property's infrastructure has seen some updates, including a 400-amp electrical service upgrade in 2013 and various plumbing repairs completed in 2015-2016. Recent history shows ongoing maintenance challenges, with multiple 311 calls in 2024 regarding garbage, debris, and driveway blocking issues near the property. The most recent health and safety inspection conducted in February 2023 was completed in August 2023, though no specific violations were noted in the available records.

Risk rating

How 307 Capp 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.
