1179 Treat Ave, San Francisco, CA 94110
The property at 1179 Treat Avenue is a one-story, two-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1910 and currently owned by Aarts Oscar A, this century-old apartment building has undergone several significant renovations and faced various challenges over the past two decades. Most notably, in 2019-2022, there were substantial improvements made to address a dwelling unit legalization matter, which included landscaping, bike parking installation, alarm system upgrades, and various interior improvements costing $45,000.
The building has received consistent maintenance attention, with two separate reroofing projects completed in 2020 ($17,800) and 2021 ($14,460), and a comprehensive electrical and bathroom/kitchen remodel in late 2021 costing approximately $14,460. The property's history includes addressing multiple safety and regulatory concerns, particularly in 2019 when several fire safety violations were documented, including issues with electrical cords, storage clearance, address numbers, fire extinguisher requirements, smoke alarms, and exit obstructions. All these violations have since been abated. The building has also undergone various infrastructure improvements, including a solar panel installation in 2010 (14 modules) and multiple plumbing and electrical upgrades between 2004-2021.
Several project proposals related to lot subdivision and additional construction have been submitted, including a 2020 proposal to legalize an existing deck and stairs, though some were withdrawn. Recent complaints and 311 calls from 2020-2024 primarily relate to exterior maintenance issues, including sidewalk cleaning and illegal parking concerns. There were also three fire complaints in 2019 and 2020 regarding hazardous materials, hoarding, and electrical systems, though most were resolved with no merit or referral to another agency. While there have been regular maintenance and improvement projects over the years, the building's most significant recent work appears to be concentrated around the 2019-2021 period, with particular attention given to addressing past violations and upgrading building systems.
