Initial analysis

Bethany Center Senior Housing, located at 3160 21st Street in San Francisco's Inner Mission neighborhood, is an 8-story, 132-unit multi-family residential building constructed in 1969. The property underwent significant safety and infrastructure upgrades between 2017-2022, including the installation of a new emergency responder radio coverage system, fire sprinkler systems, and improvements to electrical panels and plumbing infrastructure. Notable recent maintenance included the replacement of four boilers in April 2022 and the relocation of a transformer with blast walls in 2018. The building has faced several regulatory challenges, including multiple boiler permit violations in 2021 that were ultimately resolved in July 2024, and a 2024 fire violation related to sleeping area requirements that remains open.

The building has experienced recurring safety and comfort issues over the years, including complaints about construction noise and work transparency in 2022, heating system problems in 2006 and 2018, and various fire safety concerns related to sprinkler systems, alarm systems, and blocked exits. Recent fire incident reports indicate mostly minor issues such as detector activations and contained cooking fires, with no civilian injuries recorded. The property has undergone several investigations and inspections, including routine safety inspections in 2015, 2008, and 2002, and has been the subject of various work-related complaints throughout the years. Recent planning records show proposals to expand the facility's capacity by adding six new dwelling units, though these are listed as closed or approved without clear indication of implementation status. The building's recent maintenance record shows active management of safety systems and infrastructure, though some historical comfort and safety issues persist.

Risk rating

How 3160 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.
