1009 Castro St, San Francisco, CA 94114

The two-unit residential building at 1009 Castro Street in Noe Valley, owned by Benjamin Calderon and Hollman, has undergone several significant modifications since its construction in 1900. Most notably, a substantial renovation was initiated in 2020 with an approved permit costing $150,000, including a first-floor rear addition, a second-floor roof deck, interior stair modification, and third-floor improvements adding new bedroom, bath, and laundry facilities. This work, designed by architect Joram S Altman, is currently listed as issued.

The property has had multiple infrastructure improvements, including a sewer line replacement in 2010 and plumbing work related to several sewage back-up incidents between 2012-2014, suggesting some historical challenges with the building's waste management systems. Earlier modifications include various interior upgrades between 2012-2013, such as bathroom and bedroom reconfigurations, cabinetry improvements, and electrical work to modernize the second-floor bedroom. The building's exterior has seen maintenance attention, including front stair repairs in 2004 and several permit finalizations in 2008.

More recent records show recurring parking enforcement issues around the property, with citations issued for vehicles blocking driveways or parking on sidewalks between 2018 and 2023. While these parking incidents don't directly relate to building conditions, they impact the general accessibility of the property. The most recent building modifications and improvements, including the significant 2020 additions, indicate ongoing investment in maintaining and enhancing the property's functionality and living space quality.
