Initial analysis

The three-story multi-family residential building at 10-12 Saturn Street in Corona Heights, owned by Dorothy A Geoghegan Revoc T, was constructed in 1908 and contains four apartment units. The property has undergone several significant renovations and improvements since the 1980s, including kitchen and bathroom renovations in 1990 (though some permits from that period are now expired), a kitchen cabinet renovation in 1997, and underpinning work completed in 1983.

In 2002, the building underwent a routine housing inspection that revealed multiple fire safety and security issues, including problems with fire extinguishers, egress obstruction, and door security, though these violations were all promptly abated by February 2003. More recent maintenance concerns have emerged, particularly in mid-2022, when there were reports of a collapsed sidewalk, public stairway defect, and a damaged side sewer vent cover, though these issues were resolved through the Department of Public Works. The building experienced minimal incidents requiring emergency response, with only one recorded medical assist situation. Recent 311 calls have primarily concerned parking issues, with several reports of illegal parking and abandoned vehicles in the vicinity between 2021 and 2024. While the building has maintained basic code compliance since the 2002 violations were addressed, the sizable gap between major renovations suggests that some building systems may be due for updates, though no recent violations or complaints have been recorded regarding safety systems or structural concerns.

Risk rating

How 10-12 Saturn 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
35th percentile

Out of 348 buildings in this neighborhood, 226 are predicted to be safer.
