624 Pennsylvania Ave, San Francisco, CA 94107

The property at 624 Pennsylvania Ave in Potrero Hill is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Kam Henrik & Anderson Donna. The building has undergone several significant improvements over recent decades, with the most recent work in August 2023 involving dryrot repairs to the rear stairs, including ledger board, stair treads, and railings, at a cost of $6,000. The building received notable upgrades in 2014 with the installation of a solar PV system including 15 roof-mounted panels (3.39 kW), though an earlier electrical permit related to this project was cancelled.

Other historical improvements include kitchen remodelling in 1998-1999, bathroom remodelling in 1994, and various structural improvements in the early 1990s including reroofing and fireplace repairs. The property has experienced several maintenance and safety-related issues in recent years, with particular attention needed to address recurring parking violations in the vicinity, evidenced by multiple 311 calls regarding illegal parking and driveway blocking between 2020 and 2024. While most of these parking issues were resolved through enforcement action, they indicate a persistent challenge in the immediate area.

Additionally, there have been two reported incidents of graffiti (2023 and 2022) on or near the building, one of which was classified as not offensive. A sidewalk/curb defect was reported in 2022 and remains open as of October 2023, potentially impacting pedestrian access. The building's maintenance record shows regular upkeep and improvements, though it's worth noting that some earlier permits from the 1990s (for window replacements and bathroom remodelling) have expired rather than being marked as complete.
