Initial analysis

The property at 1231-1233 17th Street in Potrero Hill is a two-story, three-unit mixed-use building constructed in 1911, currently owned by Bosch Judas & Owen Kathleen. The building has experienced several significant events throughout its history, most notably a fire incident in 2003 that caused substantial damage requiring $43,000 in repairs, including electrical work, smoke damage remediation, and plumbing updates. The property has also faced safety and compliance challenges, with multiple fire safety violations related to sprinkler systems in 2020 and 2021, though these were subsequently abated. More recent concerns include maintenance issues in 2023-2024, with complaints about graffiti on both the building and surrounding sidewalk, as well as tree-related matters including a fallen tree report from November 2023 that remains open.

The building's permit history shows various improvements and modifications over the years, including a rear shed egress path upgrade in 2016 costing $5,000, and historical modifications related to egress improvements for a bar/restaurant space in the early 1990s. The property has active plumbing-related complaints from 1997 regarding hot water meter sharing with a neighboring business, which remain unresolved as of the latest data update. Recent service requests in 2024 primarily relate to street maintenance and parking issues, though one fire-related violation regarding sprinkler systems from 2022 at the nearby address 1240 17th Street was resolved. The building's maintenance record demonstrates ongoing attention to safety systems, with emergency lighting installations and various electrical repairs being completed when necessary. The property has generally responded to violations and repairs as required, though the periodic emergence of graffiti and tree maintenance issues suggests some ongoing external maintenance challenges.

Risk rating

How 1231-1233 17Th 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.
