Initial analysis

The two-unit residential building at 2904 23rd Street in San Francisco's Inner Mission has undergone significant changes since its construction in 1965, with the most recent major work occurring in 2023 when both units received new furnaces. The property experienced a serious fire incident in July 2019 that required extensive repairs, completed in 2020 at a cost of $65,000, including staircase replacement and various structural elements. An earlier unauthorized ground floor unit was formally removed in 2012, following multiple violations between 2003-2012 related to building safety and habitability issues, including water damage, mold, and security concerns. The building has undergone several major renovations and repairs, including complete rewiring of both units in 2021, window replacements in 2022, and various plumbing upgrades between 2012-2021.

Recent maintenance and compliance history shows active management of systems and infrastructure, with the most recent improvements including furnace replacement and various plumbing updates throughout the building. The property has had occasional issues with waste management and sidewalk maintenance, as evidenced by multiple 311 calls in 2024 regarding debris and abandoned furniture. While the building's historical record shows a pattern of deferred maintenance and compliance issues in the early 2000s, particularly regarding an unauthorized unit, recent years demonstrate a pattern of addressing both safety and comfort upgrades. The building's location and age have resulted in typical urban maintenance challenges, though recent permits and inspections suggest more proactive management. The most recent fire complaints in 2019-2020 were found to have either "No Merit" or "No Access To Building" designations.

Risk rating

How 2904 23Rd 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.
