Initial analysis

The two-unit residential building at 125 Saturn Street in Corona Heights, owned by Colin Carter Price, has experienced significant unauthorized modifications and permit violations in recent months. Most notably, a complaint filed in May 2023 reported the unauthorized conversion of two units into one, including the removal of a kitchen and installation of a door between units, along with an unpermitted water heater installation. This complaint, which remains in inactive status, raises serious concerns about the building's habitability and safety standards.

The property has been the subject of multiple parking-related incidents in 2023-2024, including two documented cases of sidewalk parking (May 2023 and December 2023), driveway blocking (April 2024), and an abandoned vehicle report (January 2024). These parking violations appear to involve different vehicles, with at least two cases resulting in citations or official warnings. The street adjacent to the building has experienced recurring issues with abandoned vehicles, with three separate cases recorded in 2022 (March, April, and May), though all vehicles had departed by the time officers arrived. Additionally, there were two instances of loose garbage requiring attention (November and December 2022), which were resolved through proper cleanup. While these issues primarily relate to parking and street cleanliness, the recent unpermitted modifications to the building structure represent the most concerning incident on record, particularly given its potential impact on resident safety and comfort.

Risk rating

How 125-127 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
