Initial analysis

The property at 2957 21st Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1885, this flats and duplex structure has experienced significant maintenance and habitability issues in recent years. Notably, in March 2019, serious complaints were filed regarding the building's condition, including reports of prolonged lack of heating (noted as being non-functional for at least five years), extensive mold issues in bathrooms, water leaks throughout the property, and problems with plumbing fixtures in both upstairs and downstairs bathrooms. The building's recent history also includes some structural concerns, with a 2015 permit issued for stair repairs due to dry rot, which followed a complaint about unauthorized construction work blocking the sidewalk. An earlier permit application from 2007 to construct a three-story addition was cancelled.

The property has been the subject of numerous 311 calls between 2020 and 2024, though most of these relate to external issues rather than building conditions. These include several reports of parking violations involving sidewalk obstruction and two incidents of graffiti on the mailbox (in 2020 and 2023). There have also been two instances of general street cleaning requests in 2021. The building's age, combined with these documented maintenance issues and habitability concerns, suggests ongoing challenges with property upkeep and resident comfort, particularly regarding basic systems like heating and plumbing.

Risk rating

How 2957 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, 24 are predicted to be safer.
