Initial analysis

The 6-unit, 2-story multi-family residential building at 1451 7th Avenue in the Inner Sunset, owned by Timothy Yim 2020 Living Trust, has undergone several significant safety upgrades and maintenance improvements since its construction in 1959. Most notably, in 2023 the building received a substantial fire safety upgrade costing over $17,000 to bring its fire alarm system into compliance with current San Francisco Fire Code requirements. This followed a 2022 modification to the fire alarm system that included the installation of low frequency sounders. The building is classified as a Tier 3 soft-story structure and completed its seismic retrofit in 2014, demonstrating compliance with San Francisco's mandatory seismic safety requirements.

The building's maintenance history shows regular attention to roofing needs, with reroofing projects completed in 1989, 1994, and 2015. In 2017, the property underwent a series of fire safety inspections that identified multiple violations, all of which were addressed and abated by August 24, 2017, including issues with fire escape drop ladder operation, fire extinguisher maintenance, and smoke alarm requirements. While there have been numerous 311 calls in the past year regarding parking violations and street cleaning issues, these are primarily related to the surrounding area rather than internal building conditions. The most recent street cleaning issues involved abandoned furniture and debris, which were resolved by city services. The building's fire safety systems appear to be actively maintained, with the most recent inspection in 2023 noting only a malfunctioning alarm system as the sole incident. Regular routine inspections have been conducted over the years (1999, 2002, 2009), indicating ongoing compliance with housing standards.

Risk rating

How 1451 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.

Neighborhood percentile
36th percentile

Out of 1493 buildings in this neighborhood, 956 are predicted to be safer.
