518-520 Presidio Ave, San Francisco, CA 94115

The property at 518-520 Presidio Avenue is a two-unit, two-story multi-family residential building located in Lower Pacific Heights, built in 1923 and currently owned by the Esposto Leonard Estate. The building's maintenance record shows several significant events, with the most pressing recent issue being a 2023 heating system complaint citing problems with odor and concerns about asbestos-wrapped ducts, which remains not actively abated in the Housing Inspection Services system. The property has undergone some documented improvements, including window replacements in 2020 (costing $8,000) and a complete reroofing in 2013 ($11,275).

Of particular note is a 2019 tenant buyout recorded at $55,000 for one tenant. The building has experienced some infrastructure challenges, including a broken sewer issue in 2009 and more recent sewer-related incidents in early 2024, with one event involving sewage backup from a catch basin being resolved through field work. An active grease trap complaint from 1997 remains on the books, though its current status is unclear.

The property's external environment has seen various maintenance and service requests, including multiple reports of graffiti (2012-2023), illegal postings (2020), and parking-related matters (2017). There have been several recent sewer-related incidents in the vicinity, including a flooding event in December 2024 and a sewage backup in March 2024, though these were primarily street-level issues not directly affecting the building itself. The timing of the tenant buyout and window replacement work suggests some recent building improvements, though the age of the building and its documented maintenance history indicates ongoing attention to various systems and infrastructure. The property's location has experienced typical urban maintenance issues as evidenced by the 311 calls, though these are primarily related to street-level concerns rather than building-specific problems.
