Initial analysis

The property at 409 Randolph Street in Ingleside Heights is a 2-story, 3-unit multi-family residential building constructed in 1946, currently owned by Dante and Mary Giosso Family. The building has undergone several routine housing inspections over the years, with the most recent one occurring in 2010. A notable electrical infrastructure upgrade took place in 2004 when the building converted to an underground service with 150-amp service and four meters. In early 2001, the building faced multiple violations related to safety requirements, including issues with gas meter instructional diagrams, gas shutoff tools, and apartment identification numbers, though all these violations were promptly addressed and abated by February 2001.

More recent concerns have primarily involved external issues rather than building safety or maintenance concerns. From July to December 2024, there have been several instances of driveway blocking that resulted in citations, and multiple reports of garbage and debris, including electronics and yard waste, though most of these cases were resolved. An open issue as of August 2024 involves a sidewalk defect attributed to tree root lifting. A single weed and grass complaint from August 2020 was resolved by February 2021. It should be noted that there was a tenant buyout recorded at a different property (119 Ramsell Street) in 2019 for $11,900 involving one tenant, though this is not directly related to the Randolph Street building.

Risk rating

How 409 Randolph 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
36th percentile

Out of 45 buildings in this neighborhood, 29 are predicted to be safer.
