1782-1784 39th Ave, San Francisco, CA 94122

The two-unit residential building at 1782-1784 39th Avenue in San Francisco's Outer Sunset neighborhood, owned by Douglas Lee and built in 1950, is currently undergoing significant renovations. The property is in the process of converting its ground floor garage/storage space into a new two-bedroom, two-bathroom Accessory Dwelling Unit (ADU), with associated improvements including new fire sprinklers, foundation work, and utilities, collectively costing approximately $300,000. Recent work includes the installation of new fire sprinkler systems throughout the ground floor and corridor egress (October 2024), and the replacement of foundation and bearing walls at the rear (September 2024).

Supporting infrastructure improvements are also underway, including new plumbing and electrical systems for the kitchen and bathrooms (August 2024). The building has a history of fire safety-related issues, with multiple violations and maintenance concerns recorded between 2013-2023, including sprinkler system problems and exit maintenance violations, though all have been resolved. There was a significant building violation in 2004 regarding unauthorized window installations on the south side and an unpermitted stairway, which was ultimately abated in 2021.

The property has experienced various maintenance issues in recent months, including a sewage backup and odors from November 2024, though these were promptly resolved. Historical records show some concerns about business activities in 1994, but this was quickly addressed. The building's recent construction activity has generated typical urban maintenance issues such as parking enforcement calls and debris concerns, which are being managed through regular city channels.
