Initial analysis

The two-unit residential building at 177-179 Saturn St in Corona Heights is a 1908 two-story flats and duplex structure currently owned by John M. Giosso and Sigri Selle. The building's maintenance history shows minimal recorded work, with only one notable repair from 1993 involving rotted wood in the front staircase. The property has experienced recurring issues with illegal parking, particularly between 2018 and 2024, with several incidents resulting in citations, though some cases could not be validated by responding officers. Between 2014 and 2022, there were multiple reports of abandoned vehicles in the vicinity, with most cases being resolved when the vehicles were no longer present during inspections.

Recent complaints from 2023 and 2024 have highlighted some concerns about waste management and traffic signage, including a July 2023 incident involving construction workers leaving garbage receptacles out permanently, which was addressed through verbal warnings and enforcement actions. A January 2024 report about sidewalk parking resulted in an officer response, though the initial complaint could not be validated. The property appears to have had relatively few structural or repair issues on record, with no significant safety incidents reported in recent years, though the age of the building means regular maintenance requirements should be expected. The most recent building permit from 1993 suggests limited documented improvements or modifications to the property over the past three decades.

Risk rating

How 177-179 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
68th percentile

Out of 348 buildings in this neighborhood, 111 are predicted to be safer.
