Initial analysis

The four-story, 16-unit apartment building at 446-450 Eddy Street, owned by Rizzo Properties LP and built in 1923, has experienced numerous recurring maintenance and safety issues in recent years. Most notably, there is an ongoing pattern of water-related problems, with multiple tenant complaints between 2021 and 2024 regarding plumbing leaks, including significant issues filed in 2023 and 2024 involving water damage, leaking fixtures, and associated mold concerns. The building has also faced several serious safety violations, including multiple fire code violations in 2024 related to sleeping area requirements and standpipe systems, though some violations from 2024 were marked as "Condition Corrected." Historical violations from 2018-2019 showed a range of issues including interior surface damage, safety concerns, and the need for updated fire safety equipment, all of which were addressed through various permits totaling approximately $6,000 in repairs.

Recent records from 2024 indicate ongoing concerns about building maintenance and security, including issues with the front gate lock in 2021, exterior signage compliance in 2023, and multiple reports of garbage and debris in the surrounding area. Fire safety systems appear to be a continuing concern, with several fire code violations noted in 2023-2024 related to sprinklers, alarms, and extinguishers, though historical fire incidents show only minor events such as contained cooking fires and false alarms, with no reported civilian injuries. The building's maintenance history includes various permitted repairs and upgrades, such as an exhaust fan installation in 2020 and plumbing work, but many older permits from the 1980s remain on record for completed cleaning and maintenance work.

Risk rating

How 446-450 Eddy 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

Out of 172 buildings in this neighborhood, 76 are predicted to be safer.
