Initial analysis

This two-unit multi-family residential building, located at 427 12th Avenue in the Inner Richmond neighborhood, was constructed in 1922 and is currently owned by Garry Gavney. The property has a documented history of maintenance and incident reports spanning several decades, with the most significant event occurring in 1997 when the building sustained fire damage, followed by repairs completed later that year. In 1997, repairs were made to rear access stairs and lath/plaster, though a reroofing permit from the same year expired. A housing inspection complaint was filed in 2000 regarding unpermitted kitchen remodeling, though this issue is now marked as not active.

The building has experienced recurring sewer-related issues, with multiple documented sewage backup incidents between 2016 and 2021, specifically involving the 4-inch sewer vent that required attention from PUC Sewer Operations each time. The property has also had issues with graffiti, most recently documented in 2023, and faced sidewalk sanitation challenges in 2021. A parking enforcement incident was recorded in 2019 regarding a vehicle blocking the driveway, and there was one case of an abandoned vehicle report that was deemed to have no merit. While the building has experienced several maintenance and sanitation issues over the years, all reported incidents have been officially resolved according to city records.

Risk rating

How 427 12Th Ave'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.
