Initial analysis

The three-story, seven-unit multi-family residential building at 3025 21st Street in the Inner Mission, built in 1880, has undergone significant maintenance and improvement work in recent years. Most notably, the building completed its mandatory soft-story seismic retrofit (Tier 3) in 2016, demonstrating compliance with San Francisco's safety requirements. In 2018, substantial improvements were made, including the installation of eight tankless water heaters, underground plumbing work for two bathrooms, electrical upgrades, and the conversion of the basement into a more functional space. These renovations also included lowering the basement floor for increased ceiling height, replacing concrete slabs, repairing and widening the subterranean concrete stairwell, and creating new walkways around the building's exterior.

The building has a documented history of addressing safety concerns, with a significant set of violations recorded in December 2007 related to fire escape maintenance, egress obstructions, and smoke detection systems - all of which were abated by March 2008. Earlier issues from 1995-1996 involved concerns about mildew, sanitation, and unauthorized modifications, though these were also resolved. Recent maintenance has included roof replacement in 1998 and various structural improvements. The property has faced some recurring infrastructure challenges, most recently evidenced by two sewage backup incidents in early 2024, and there have been multiple reports of garbage and debris on the surrounding property throughout 2024. A current permit under review (as of 2024) pertains to adding two ADUs at the rear of the basement, suggesting ongoing development activity at the site.

Risk rating

How 3025 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, 1547 are predicted to be safer.
