618 Excelsior Ave, San Francisco, CA 94112

The two-unit residential building at 618 Excelsior Ave, owned by Alfred Datlim Kwong, is a 1926 single-story multi-family dwelling located in San Francisco's Excelsior neighborhood. The property has undergone several significant modifications and improvements over the years, most notably in 2015-2016 when modifications were made to legalize an in-law bathroom and kitchen unit.

A substantial renovation occurred in 2003 involving the addition of a half-bath and three rooms in the garage level, along with electrical upgrades including a new 100-amp service and extensive wiring improvements. The building recently received a new roof in October 2023 and installed a solar PV system in August 2023, demonstrating ongoing maintenance and sustainability efforts. The property faced regulatory scrutiny in 2014 when a complaint was filed regarding unauthorized modifications and occupancy violations, including work done without proper permits, unapproved wiring and plumbing, and concerns about occupancy separation between the garage and habitable rooms.

These violations were subsequently abated in July 2016, following the legalization efforts. More recent concerns have primarily centered around street maintenance and parking issues, with multiple 311 calls in late 2024 regarding garbage, debris, and parking violations near the property. The building's permit history shows regular maintenance and upgrading of systems, including plumbing and electrical work, with the most recent significant improvements being the roof replacement and solar panel installation.
