503 Divisadero St, San Francisco, CA 94117

503 Divisadero Street is a two-unit, two-story residential building constructed in 1900, currently owned by Skyblake Properties and classified as a flats/duplex structure. The property has undergone several significant improvements over the past decade, including the installation of a 6.27 kW solar panel system in 2011, electrical system upgrades in 2011 consolidating meter mains, and various plumbing improvements such as gas line extension (2014) and sewer work (2010).

Structural enhancements include chimney removal and lateral upgrades to the front of the building completed in 2010, as well as earlier maintenance work on the front stairway (1988) and flooring modifications (1985). The building's recent history has been marked by multiple incidents of graffiti in late 2024 and early 2025, affecting various surfaces including the building itself, nearby poles, and sidewalk areas. The property experienced one minor building fire related to equipment failure, though no civilian injuries were reported.

Two fire complaints were filed in 2019 - one regarding blocked exits (found to have no merit) and an uncategorized complaint that was referred to another agency. Infrastructure maintenance has been addressed appropriately over the years, with records showing attention to roofing (1990), sidewalk repairs (2006), and various utility improvements. The building's permit history indicates regular upkeep and modernization, with particular attention paid to electrical and plumbing systems between 2010 and 2014, while some older permits from the 1980s regarding sound insulation and flooring work have expired without record of completion.
