Initial analysis

The property at 2750-2752 21st Street is a three-story, 6-unit multi-family residential building with ground floor commercial space, built in 1905 and currently owned by Marwan & Doris Masri Revoc. The building has undergone several significant safety upgrades in recent years, most notably a comprehensive fire alarm system upgrade in 2024-2023 that includes new manual pull stations, smoke detectors, horn/strobes, and low-frequency audible alarms in sleeping areas to enhance resident safety. The electrical systems received a substantial boost with a 400A service upgrade in 2017, and the building has maintained basic infrastructure through various reroofing projects in 1994, 1995, and 2003.

Historical records from 2002 show a cluster of safety violations related to fire safety, security, and lighting issues, including problems with egress, fire extinguishers, and smoke detectors, though these were all abated by December 2002. A more recent complaint from 2013 noted concerns about lead paint, plumbing issues, and mold, but this was marked as not active. The building experienced multiple fire alarm system malfunctions between 2019 and 2020, though these were all confirmed as false alarms with no civilian injuries. The property has been the subject of numerous 311 calls in 2024-2025, primarily related to garbage and debris issues, with multiple cases involving abandoned furniture and loose garbage being reported and resolved. Recent improvements to the building's safety systems and the prompt resolution of municipal service calls suggest active management of the property's maintenance needs, though the frequency of recent garbage-related complaints might indicate ongoing challenges with waste management in the area.

Risk rating

How 2750-2752 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.
