Initial analysis

The property at 2612 21st Street in San Francisco's Inner Mission neighborhood is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by the Ralph C Hendricks Bypass Trust. The building has experienced several maintenance and safety issues over the past two decades, with the most significant cluster of violations occurring in October 2019, including problems with window latches, electrical outlets, smoke and carbon monoxide detectors, and subfloor conditions, all of which were documented in multiple violation notices and ultimately addressed by November 2019 through repairs estimated at $25,000. Prior to this, the building underwent various structural and safety improvements, including rear stair repairs with grab rail installation in 2012, deck board replacements and dry rot repairs in 2011, and the replacement of an HVAC furnace in 2015.

The property has a history of electrical and heating system challenges, particularly evident during complaints in 1996 when tenants reported inadequate heating and multiple electrical issues, including non-functional outlets in bathrooms and kitchens, though these problems were eventually resolved. Other repair work has included addressing water damage and dry rot in various areas of the building. More recent history shows numerous parking-related incidents near the property, with multiple reports of vehicles blocking driveways and parking illegally on sidewalks between 2021 and 2024, though these issues are external to the building's condition and management. The most recent building maintenance activity was recorded in 2019, with no major violations or repairs noted in the past four years.

Risk rating

How 2612 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.
