Initial analysis

The property at 453-455 34th Avenue is a three-story, two-unit multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1987, the building has undergone several significant changes over its lifetime, including a horizontal extension with garage expansion and rear stair addition completed in 1986, and a window replacement project in 2011 that cost $4,500.

The building has several concerning issues that have persisted over the years. Most notably, there are active violations from 2017 regarding seismic restraint requirements for hot water heaters and other plumbing/electrical compliance matters that have not been resolved, though these might be related to a single complaint filed that year about possible illegal basement units. A more recent and serious issue emerged in September 2022, when a tenant reported mold growth in bedrooms and closets, affecting both her and her daughter's health, with the problem allegedly starting in December 2020 after multiple complaints to the landlord about inadequate inspection or remediation. The building has also experienced ongoing parking enforcement issues in the vicinity, with multiple reports of blocked driveways and sidewalk parking between 2021 and 2024, though these are external to the building itself.

Risk rating

How 453-455 34Th 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

Out of 1040 buildings in this neighborhood, 697 are predicted to be safer.
