540-542 4th Ave, San Francisco, CA 94118

The property at 540-542 4th Avenue in San Francisco's Inner Richmond neighborhood is a century-old, 2-unit multi-family residential building owned by David Samson. The building has undergone several significant improvements over the years, with the most notable recent upgrades including solar panel installations (2015), electrical system modernization (2015), and sewer line maintenance (2021). The 2015 solar upgrade included the installation of two solar PV systems totaling 4.25 kW across 17 roof-mounted modules, along with infrastructure improvements such as a new main distribution panel, EV charging infrastructure, and updated grounding system.

The building's maintenance history shows attention to structural integrity, with important repairs completed in 2000 including reinforcement of the garage structure and foundation work. Recent issues affecting the property include multiple reports of driveway blocking incidents in late 2023, though these are external parking issues rather than building-related problems. Of particular note are several sewer-related incidents in 2022-2023, including flooding on the property in January 2023.

The building experienced construction-related noise complaints in November 2023, with two reports filed within a week of each other. While the building's permit history shows regular maintenance and upgrading of systems, including a re-roofing project in 2015 costing $15,850, the recent sewer incidents and construction noise complaints may indicate potential infrastructure strain or ongoing maintenance activity. The property has no recorded tenant buyouts under the current address, and all permits related to building improvements have been properly completed through official channels.
