Augrented Insights Report

The three-unit residential building at 139-143 Blake Street in the Lone Mountain neighborhood, owned by the Roy C Lee Revocable Living Trust, has experienced significant ongoing maintenance and safety issues, particularly in recent years. Built in 1900, this 2-story flats and duplex structure has been the subject of numerous building complaints and violations since 2016, with the most recent issues from December 2023 citing rubbish, electrical problems, and a unit fire. The property has repeatedly faced challenges related to mold, rodent infestations, hoarding conditions, and illegal dwelling unit concerns.

Multiple building permits were filed in 2024 for ADU modifications, while in 2023, several permits were issued to address various compliance issues including gas vent installation, lead paint encapsulation, and extensive bathroom and kitchen repairs across multiple units, particularly unit 143. The building has a documented history of electrical and plumbing issues, with permits showing work on kitchens, bathrooms, and water heaters. An active complaint from 2022 regarding wall leaks and mold was noted as still active.

The property has undergone several compliance actions, including a 2016-2018 process addressing multiple violations related to egress obstruction, damaged walls, sanitation, window repairs, wiring issues, lead paint concerns, inadequate lighting, mold, and weatherproofing problems. Historical records show previous building code compliance issues from 2006 regarding smoke detector requirements, with documented changes in use or occupancy. Recent planning records highlight ongoing investigations into unauthorized unit conversions and illegal dwelling units, with various proposals for ADU modifications currently under review. The property has also undergone multiple tenant buyouts, with the most recent transaction in September 2024 for two tenants totaling $115,000.
