Initial analysis

The property at 1059 Montgomery Street in Telegraph Hill is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by the Won Marital Trust. The building is undergoing a significant kitchen and bathroom remodeling project in the 3rd floor unit, with permits filed in July 2024 for window and door replacements at an estimated cost of $30,000. A permit from 1994 for reroofing work is listed as expired.

The building's recent history shows minimal internal issues, though there was one building complaint in November 2021 regarding workers carrying sheetrock without visible permits, which was promptly abated within one day. The surrounding area has experienced several maintenance and compliance issues in recent years, including multiple instances of street cleanliness concerns, parking violations, and hazardous materials reports. Notable external incidents include a blocked parking space by a dumpster in February 2022, a flickering streetlight issue in January 2022 that required repeated assessments by PG&E, and various reports of garbage and debris that were subsequently resolved. The most recent incident recorded was in November 2024 regarding a discarded mattress, while other 311 calls from 2023-2024 primarily involved street cleaning matters. A fire service call was recorded for the property, though it was classified as a "500 Service Call, other" with no civilian injuries reported.

Risk rating

How 1059 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
34th percentile

Out of 684 buildings in this neighborhood, 451 are predicted to be safer.
