Initial analysis

The property at 173-175 Valparaiso Street in San Francisco's Russian Hill neighborhood is a two-unit, two-story multi-family residential building constructed in 1930, currently owned by Berry Hershel & Elsa. The building has undergone several significant maintenance updates over the years, including a comprehensive window improvement project in 1996 when 35 aluminum windows were installed, and a sewer lateral replacement completed in May 2022, which indicates attention to infrastructure maintenance. Historical records show a roofing project from 1995 and a furnace replacement in 2008, though the latter was marked as expired in the permit system.

The building's recent history shows minimal internal issues, with only one Rent Board-related service request in October 2023 regarding fee housing inventory matters, which was resolved with a unit count change. The property's external maintenance history includes several 311 calls related to street cleaning in 2016-2018, typically involving loose garbage on the street, though these were general neighborhood issues rather than building-specific problems. There was one significant plumbing incident in 2011 involving a sewage backup, and the property underwent substantial exterior improvements in the mid-1990s. The most recent building-related activity was in 2023, when the Rent Board modified the unit count and communicated with the property owner, though this event did not indicate any structural or maintenance concerns. The property's maintenance record shows regular upkeep of essential systems, with particular attention paid to windows and the building's exterior components during the specified periods.

Risk rating

How 173-175 Valparaiso 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 1133 buildings in this neighborhood, 68 are predicted to be safer.
