Initial analysis

The 6-unit, 3-story multi-family residential building at 1137 Montgomery Street in Telegraph Hill, owned by Paul J Kostuchenko, was constructed in 1924 and has undergone several significant improvements to maintain safety and compliance with modern standards. Most notably, the building completed mandatory seismic strengthening measures in 2019, following a substantial soft story retrofit in 2016 that cost approximately $80,000 and placed the building in Tier 3 of the San Francisco Soft Story program. These improvements demonstrate the owner's commitment to maintaining structural safety, though a recent fire complaint regarding exit maintenance was filed in December 2024 that warrants attention.

The building has received regular maintenance over the years, including window replacements in the mid-1990s, reroofing in 1989, and updates to essential systems such as a wall furnace replacement in 2016 and water heater replacement in 2010. The property has undergone three routine housing inspections between 2001 and 2010, all of which were promptly abated. Recent activity around the property between late 2023 and 2024 has primarily involved parking enforcement issues, with multiple reports of blocked driveways and some concerns about garbage and debris. While these external issues don't directly impact building safety, they may affect resident convenience. The most recent building permit activity suggests that while major structural improvements have been completed, there may still be ongoing attention needed for building systems and maintenance, as evidenced by the recently filed fire complaint regarding exit maintenance and the street space permit issued in 2018.

Risk rating

How 1137 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, 383 are predicted to be safer.
