234-236 9th Ave, San Francisco, CA 94118

The two-unit residential building at 234-236 9th Avenue in the Inner Richmond, owned by Huey Paul Poy Sin and dating back to 1911, has undergone several notable improvements over the past few decades. Most significantly, in September 2022, the property received a substantial window upgrade costing $22,584, involving the replacement of three street-visible windows with more efficient aluminum wood-clad units, transitioning from gliders to casement styles with improved U-factor ratings.

Earlier improvements included a sidewalk permit issued in 2005 and a reroofing project from 1997, though the latter permit has expired. The building has experienced numerous parking-related issues in recent years, particularly between 2019 and 2025, with multiple incidents of driveway blocking requiring parking enforcement intervention.

Between 2019 and 2022, there were at least eight documented cases of vehicles blocking the driveway, with citations issued in several instances, including notable cases involving a VW Bug, Toyota Prius, and a Fiat Cooper. The most recent parking-related incidents occurred in January and September 2025, while other service calls include a garbage and debris complaint in September 2024. The property's maintenance history indicates regular upkeep, with the most recent major improvement being the window replacement project, which has enhanced both energy efficiency and curb appeal while maintaining the building's historical character through careful attention to existing wood trim.
