501-503 Connecticut St, San Francisco, CA 94107

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. Recent activity at the property has primarily involved standard maintenance issues, as evidenced by multiple 311 calls in 2024 regarding sidewalk cleaning, garbage management, and tree maintenance. The most recent work permit, filed in December 2022, relates to code-compliant door replacement, indicating continued attention to building code compliance. The property maintains a mixed-use configuration with both residential and commercial components, though recent complaints regarding signage coverage and other minor issues have been resolved through normal city processes.
