Initial analysis

The 6-unit multi-family residential building at 470 Frederick Street, owned by K-r Trust, is a three-story structure built in 1900 in the Parnassus/Ashbury Heights neighborhood. The property has undergone several significant improvements over the years, with the most recent maintenance work being conducted in early 2024, including bathroom and kitchen updates in Unit #1, along with associated plumbing work. The building has demonstrated proactive maintenance and safety upgrades, including a completed seismic soft-story retrofit (Tier 3) in 2015, a comprehensive reroofing project in 2022, and the installation of an improved fire alarm system with low-frequency sounders in 2018. Infrastructure upgrades have included a 600A electrical panel survey and plumbing improvements such as sewer replacement and water heater installation.

The building's history includes several resolved building violations from 2003-2017, primarily related to stairs, handrails, and gas meter requirements, which were all addressed and abated. There were also two complaints in 2000 regarding unauthorized backyard parking modifications that were resolved. The property has undergone routine housing inspections and remains in compliance with safety requirements, though a recent October 2023 complaint regarding unpermitted plumbing work has been recorded. Recent 311 calls have primarily concerned exterior maintenance issues like garbage/debris removal and sidewalk cleaning, with all cases being resolved promptly. The building's maintenance record shows regular upkeep and responsiveness to issues, with no active tenant buyouts recorded.

Risk rating

How 470 Frederick 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.

Neighborhood percentile
37th percentile

Out of 526 buildings in this neighborhood, 331 are predicted to be safer.
