Initial analysis

The 2637-2641 21st Street property in the Inner Mission is a three-story, four-unit multi-family residential building constructed in 1900, currently owned by Jaime and Martha Gomez. The building has undergone several significant repairs and faced multiple compliance issues in recent years, with the most pressing concerns emerging in 2022. During that year, multiple violations were recorded and subsequently addressed, including water damage repairs, window replacements, outdoor stair code compliance, and roofing work, all completed by February 2023 at a total cost exceeding $30,000. Historical issues in 2015 included a serious sanitation problem with sewage backups and rodent concerns, though these were resolved.

Currently, there are active complaints from 2025 regarding electrical concerns, including exposed wiring and deteriorated equipment, suggesting ongoing infrastructure maintenance challenges. The building's maintenance history shows regular attention to basic upkeep, including plumbing work in 2016 and multiple roofing projects, with the most recent 2023 reroofing work. The property has experienced recurring issues with sidewalk parking violations, with multiple citations issued between 2018 and 2024, though these are external to the building's condition. A routine inspection was conducted in 2023, which suggests some level of ongoing property oversight, but the recent electrical complaints indicate that some maintenance issues may persist.

Risk rating

How 2637-2641 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.
