428-432 Lyon St, San Francisco, CA 94117

The multi-family residential building at 428-432 Lyon Street, located in the Park North neighborhood, is a three-unit structure built in 1900 and currently owned by Alexander Chi Ip. The property has undergone significant renovations and addressed multiple code compliance issues since late 2018. Most notably, in 2019, the building underwent comprehensive interior renovations costing approximately $445,000, which included the installation of smoke and carbon monoxide detectors, fire extinguishers, and security improvements.

This work was initiated in response to a series of violations filed in October 2018 related to fire safety and security requirements. The building received substantial system upgrades including a complete electrical rewiring, new plumbing infrastructure for all units, and the installation of high-efficiency gas furnaces for each unit in June 2019. The property has faced several compliance challenges that have been subsequently addressed, including the installation of rated walls and doors for a rated egress corridor in 2020, following a complaint about protected exit connections.

A notable complaint from August 2018 regarding heat issues and fire extinguisher concerns preceded significant renovations that improved building safety. While there have been various maintenance and safety inspections over the years, including a 2003 routine inspection, all major violations from 2018-2019 have been formally abated as of February 2020. Recent exterior issues documented through 311 calls include reports of graffiti, hazardous materials, and encampments near the property, which were addressed by city services. The building's most recent work remains focused on ongoing exterior and public space maintenance, with the last major renovation work completing in 2019-2020 period.
