662-664 10th Ave, San Francisco, CA 94118

The two-unit residential building at 662-664 10th Avenue in San Francisco's Inner Richmond neighborhood, owned by Teleforo Philip John S, has a notable history of maintenance and safety compliance issues. Built in 1915 as a two-story flats and duplex structure, the property has undergone several significant works, including a $17,115 reroofing project in 2020 and various street space permits in 2018-2019.

The building faced substantial violation notices in March 2017, particularly regarding safety and fire safety equipment, including the lack of carbon monoxide detectors on each floor, missing fire extinguishers, fire proofing issues, and lead paint concerns. While these violations were officially abated in November 2024, they indicate previous critical safety compliance challenges.

More recently, in August 2024, the property received complaints regarding illegal construction and hoarding in the garage area, though these complaints are listed as "Not Active." The building's maintenance history shows some positive actions, such as window replacements in 1994 and stucco repairs in 2012, while recent parking enforcement records from 2023-2024 reveal ongoing issues with vehicles blocking driveways, though these are typical urban challenges rather than building-specific problems. The most recent known routine safety inspections occurred in 2017, with a prior insufficient heat complaint from 2002 being resolved within weeks. The property has maintained its classified use as a multi-family residential building throughout its history.
