Initial analysis

The 1120-1126 Montgomery Street property is a 3-story multi-family residential building located in Telegraph Hill, containing 6 units and owned by Mulberry Tree LP. Built in 1906, this apartment building has experienced recurring maintenance issues over the past two decades, with the most significant cluster of violations occurring in late 2019 through early 2020. These violations predominantly involved window-related problems, including assembly operation failures, weather seal issues, and lead paint concerns. A blocked exit fire complaint was also recorded and resolved in March 2020. The property has undergone several structural and safety-related improvements over the years, including the installation of fire sprinklers in 2000, garage construction in 1998, and dry rot repairs to the rear stairway in 1999. More recent building maintenance history shows ongoing challenges with windows, as evidenced by multiple complaints between 2018-2020 regarding leaks, draftiness, and hardware failures.

The building's infrastructure maintenance includes a reroofing project completed in 1995, though several permits from earlier years, including garage construction, fire sprinkler installation, and a dry rot repair project, have since expired. The property has had periodic issues with various systems, as documented in complaints from 2012 regarding electrical reliability and mold growth, and from 2017 involving animal intrusion and stairway stability concerns. Outside the building itself, there have been multiple parking enforcement requests in recent years, with several cases resolved through citations, though some were found to be invalid due to incomplete reporting information. The most recent activity related to the property consists of parking enforcement cases from 2022-2023, though these do not directly impact building conditions or resident experience.

Risk rating

How 1120-1126 Montgomery 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 684 buildings in this neighborhood, 622 are predicted to be safer.
