Initial analysis

The three-unit, three-story multi-family residential building at 166-170 Valparaiso Street in Russian Hill, owned by Hershel and Elsa Berry, has undergone significant renovations and improvements since 2021. The 1912 flats and duplex structure has received substantial updates including building leveling and structural reinforcement work completed in 2021 at a cost of $50,000, window replacements throughout the building, and comprehensive kitchen and bathroom renovations across multiple floors. In early 2021, all units received electrical panel upgrades, new wiring, and plumbing improvements, including the replacement of galvanized steel pipes with copper. The most recent work, completed in 2022, involved kitchen modifications on the third floor.

The building's maintenance history shows attention to both safety and modernization, with the owners addressing various building code requirements and improving resident amenities. A notable incident occurred in September 2021 when there was a complaint about potential trespassing during construction work, though this was promptly addressed and marked as "Not Active." The property experienced a building violation in 2020 related to unpermitted stair repairs, which was resolved through proper permitting. While there have been multiple street cleaning and maintenance calls in the surrounding area between 2017 and 2021, these are typical for urban residential settings and do not directly reflect on the building's condition or management. The most recent records from 2023 show no active violations or complaints, suggesting current compliance with building codes and regulations.

Risk rating

How 166-170 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, 419 are predicted to be safer.
