548-550 Russia Ave, San Francisco, CA 94112

The two-unit residential building at 548-550 Russia Avenue in the Excelsior neighborhood, owned by Alanzalon Crispin D & Alanz, has undergone several significant improvements since its construction in 1979, when it was built as a two-story flats & duplex structure. In 2017, the property received substantial exterior upgrades including new siding installation (costing $15,000) and re-roofing work ($1,000), while also incorporating green technology with the installation of multiple solar panel systems - two sets of 20 and 19 modules respectively, installed in November 2017, and two additional sets installed in August 2015, demonstrating a commitment to sustainable energy (total solar investments exceeding $30,000).

Prior to these improvements, the building underwent important structural work in 2007, including a voluntary foundation upgrade, dry rot repairs, bedroom wall and ceiling repairs, and the replacement of rear windows with double-pane units (costing $30,000). The building's recent history reflects regular maintenance and modernization efforts, though there have been some environmental and safety concerns in the surrounding area. In 2023, there were incidents of graffiti near the property (including one on ATT property in October and a city receptacle in March), and multiple reports of illegal parking incidents, particularly concerning vehicles parking on sidewalks.

While these exterior maintenance issues are primarily related to the neighborhood and not the building itself, they do provide context about the surrounding area. The property's documented maintenance history suggests regular upkeep and prompt addressing of infrastructure needs, with the most significant investments focused on exterior improvements, energy efficiency upgrades, and structural integrity enhancements. The building's permits and improvements indicate ongoing investment in maintaining and upgrading the property, with particular attention to energy efficiency through the installation of solar panels and modern building materials like Hardy Plank siding.
