Initial analysis

The property at 501-503 Connecticut Street in Potrero Hill is a two-unit, two-story mixed-use building constructed in 1927, currently owned by Eli Bocek-Rivele and Xiaohan Wang. The building has undergone several significant improvements in recent years, with the most notable being the installation of energy-efficient features including a Mitsubishi heat pump system, tankless water heater, and a 2.35kW solar photovoltaic system in 2021-2023. In 2021, substantial window restoration work was completed, including the replacement of 10 casement sashes with historically accurate true divided lites. A recent safety concern was noted in November 2024 with a sewage back-up discharge, though this has since been resolved.

The building's history includes some notable challenges, particularly in 2011-2012 when multiple building violations were recorded regarding unauthorized construction work, including a roof deck built without proper permits and various unpermitted interior modifications. These issues appear to have been resolved by April 2012. The property has maintained active compliance with City requirements since then, with recent improvements focusing on energy efficiency and building maintenance. Regular maintenance and infrastructure upgrades have included electrical system improvements (including a 400-amp service upgrade), plumbing updates, and various building code compliance updates, demonstrating ongoing investment in the property's upkeep and safety systems.

Risk rating

How 501-503 Connecticut 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
