115-117 9th Ave, San Francisco, CA 94118

The two-unit residential building at 115-117 9th Avenue in Lake Presidio, owned by Tanaka Setsuko J & Isao, has undergone several significant maintenance and improvement projects since its construction in 1916. Most recently, in 2019, approximately $9,000 was invested in repairing rotted rear stairs, which was completed successfully. Earlier maintenance included a complete reroofing in 2015 at a cost of $9,500, following previous roofing work documented in 2000 and 1988.

The property has also seen substantial safety improvements, such as the installation of a dedicated receptacle for a stair lift in 2008. Other historical improvements include a bathroom remodel and concrete slab repair completed in 1990, and the application of aluminum siding in 1986, though the related permits from that period have since expired. The building's recent history has been relatively quiet in terms of major issues, with only routine maintenance and infrastructure updates being recorded.

There have been several 311 calls related to the immediate vicinity of the property, including a parking violation in September 2024 and a flickering streetlight issue in 2019, both of which were resolved through normal city processes. Notably, there were multiple reports of abandoned scooter/motorcycle vehicles in the immediate vicinity between 2016-2017, though these were external to the property and were consistently resolved when city authorities responded to the reports. The building appears to be well-maintained, with regular updates to critical elements like roofing and safety features, as evidenced by the active permit history spanning several decades.
