1964-1966 Union St, San Francisco, CA 94123

1964-1966 Union Street is a two-unit, two-story multi-family residential building located in San Francisco's Cow Hollow neighborhood, originally built in 1924 and currently owned by Ap Union Ii LLC. The property underwent significant development between 2016-2019, including the controversial addition of two new dwelling units at the rear of the existing structure, which was completed in 2019 with a construction cost of $525,000. This addition generated a current active building violation filed in December 2023 regarding an expired demolition permit from 2019, which had been previously issued for $2,500.

The building's recent history shows considerable improvement work, including a complete remodel of ground floor retail space in 2016-2017 costing approximately $150,000, which included the installation of both electric and non-electric signs for the Bonobos retail tenant, and various plumbing and electrical upgrades including a new 400 amp service and additional cooling systems in 2017-2018. The property's maintenance record shows regular upkeep, including reroofing work completed in 2017 at a cost of $25,250. Several street-related issues have been documented near the property, particularly regarding blocked driveways, with multiple citations issued between 2023-2024.

There was also a significant tenant buyout recorded in 2015 for $100,000 involving one tenant at the 1964 Union Street address. The building's recent history also includes two active complaints filed in 2023 - one regarding vacant commercial space in March 2023 and a more recent complaint in December 2023 concerning expired permits. These recent compliance issues, particularly the December 2023 violation regarding an expired demolition permit, represent the property's most significant building code concern to date.
