Initial analysis

The property at 2608-2610 21st Street is a two-story, four-unit multi-family residential building constructed in 1900, currently owned by the Ralph C Hendricks Bypass Trust. The building has a concerning history of maintenance and safety issues, with the most recent active violations filed in November 2022 relating to gas safety requirements (shutoff tool, instructional diagram) and smoke/carbon monoxide detector compliance. Previous significant complaints include multiple instances of heat and mold problems between 2010-2012, and a 2017 complaint about mold issues and other plumbing concerns. The building has undergone some infrastructure improvements, including a heating system installation in 2012, water heater replacement in 2013, and various repairs to address structural and safety issues such as illegal iron bar removal and window wood replacement in 2002, though some permits from earlier years expired. A cluster of fire safety violations was documented in February 2000, though these were abated by March 2000. Recent maintenance activity includes attention to tree maintenance near the property in 2017, with the Department of Public Works noting that the issue would be addressed during routine block-wide pruning. The building's documented history raises concerns about recurring maintenance issues, particularly related to heat and mold, though some improvements have been made over the years.

Risk rating

How 2608-2610 21St 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

Out of 2380 buildings in this neighborhood, 2118 are predicted to be safer.
