1 18th Ave, San Francisco, CA 94121

The 2-unit multi-family residential building at 1 18th Ave, built in 1912, has undergone substantial improvements over the past two decades. Most recently, in September 2023, the property was upgraded with a solar PV system and two Tesla Powerwall batteries, marking the building's transition to sustainable energy. Significant structural and safety improvements have been implemented, including a foundation upgrade with drilled piers and shear walls in 2012 (cost: $95,000), complete window retrofitting in 2012 ($9,000), and the addition of two dormers to the third floor roof (2018, $100,000).

The building has received regular maintenance attention, with a new roof installed in 2012 ($9,900), window updates, and various structural repairs including brick waterproofing work in 2011 ($6,000). Safety systems have been a priority, with multiple furnace and heating system upgrades, including the installation of six space heaters in 2012 and the replacement of two furnaces. The property has experienced several carbon monoxide detector activations, though none resulted in actual CO presence or civilian injuries.

Fire incidents have primarily consisted of false alarms and good intent calls, with one gas leak incident recorded. Recent municipal service requests (2023-2024) have primarily concerned external issues such as abandoned vehicles, tree maintenance, and graffiti, rather than structural or safety concerns with the building itself. The property appears to be well-maintained overall, with regular updates to systems and infrastructure, though prospective tenants should be aware of the building's age and history of occasional safety system activations.
