631-641 Jackson St, San Francisco, CA 94133

The property at 631-641 Jackson Street is a three-story, 14-unit multi-family residential building constructed in 1907, currently owned by Hing Yip Co Inc. The building has undergone several significant transformations in recent years, including a change of use from a flower shop to a sweet retail shop in 2023, and previously to a coffee baking shop limited restaurant in 2017, with corresponding interior improvements. Major maintenance work has included reroofing projects in 2016-2018, installation of an automatic fire suppression system in 2010, and multiple plumbing updates related to grease trap installations and drainage issues.

The building has a documented history of fire safety concerns, with multiple fire code violations noted between 2006 and 2023, including recent violations in December 2023 related to extinguishers and Class K cooking equipment. There have been several instances of vacant commercial space requiring monitoring under the Vacant Storefront Ordinance between 2018 and 2022. Notable infrastructure issues were reported in 2016 involving drainage problems that affected neighboring properties, though these were subsequently addressed.

The property has also experienced recurring issues with garbage and debris management, as evidenced by multiple 311 calls throughout 2024, along with some noise complaints. Historical violations from 2002 included fire escape maintenance and security lock issues, though these were resolved. The most recent active complaint as of early 2023 involves unauthorized work related to awning installation.
