Initial analysis

The property at 667-669 7th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1923 and currently owned by the Helen Yip Ong Revocable Trust, this flats/duplex structure has undergone significant recent improvements. As of 2023-2024, major renovations have included the creation of a ground floor accessory dwelling unit (ADU) at an estimated cost of $236,854, which was permitted in June 2023 and requires the installation of ground floor fire sprinklers and a full building fire alarm system. Additional substantial work has encompassed comprehensive kitchen and bathroom remodeling in both units, voluntary lateral strengthening with plywood shear walls, and various infrastructure upgrades including the installation of a 400-amp meter main service and a Ufer ground system.

The building's recent improvements also include complete electrical rewiring and plumbing updates across various areas including kitchens, bathrooms, and living spaces, suggesting a thorough modernization of the property. Notably, there have been no reported safety violations or major maintenance issues in recent years, and the building has been actively maintained with proper permits for all significant work. The property has experienced recurring issues with driveway blocking, with seven citations issued between 2021 and 2024, indicating ongoing challenges with parking enforcement in the area. All other 311 calls related to the property have been resolved promptly, including recent reports of curb defects and street cleaning needs. The extensive recent upgrades, while improving the property's value and functionality, indicate substantial investment in modernization rather than addressing critical safety concerns.

Risk rating

How 667-669 7Th 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.
