633-635 Castro St, San Francisco, CA 94114

The three-unit multi-family residential building at 633-635 Castro Street, owned by Michael Sindicich, was constructed in 1910 and is classified as a TIC building with four units or less. The property has undergone several significant structural improvements in recent years, with the most recent work completed in January 2024 involving reinforcement of the retaining wall at the southeast corner. Previous retaining wall improvements were made in 2018, including modifications to increase its height and width.

The building has seen comprehensive maintenance and modernization, including a major renovation in 2017 that involved removing a bearing wall between the kitchen and living room in the second-floor unit, updating bathrooms and kitchens, and replacing the rear staircase, all totaling approximately $51,000 in improvements. Other notable improvements include window replacements in 2006, interior wall alterations in 2009, and plumbing and electrical upgrades in 2019 for kitchen and bathroom remodeling. The building's maintenance history indicates attention to safety concerns, particularly regarding fire safety and structural integrity. While there were multiple violations noted in 2005 related to interior surfaces, fire safety, stairs, and self-closing doors, these were all addressed and abated by August 2005.

A 2009 complaint about missing fire resistive surfaces was resolved by December 2009. The property has maintained active responses to safety concerns, with regular inspections and prompt attention to violations. The building's history includes some infrastructure challenges, such as dry rot on rear stairs (2005), electrical issues (2005), and insulation concerns between floors (2005), all of which appear to have been addressed through subsequent repairs and upgrades. The most recent retaining wall reinforcement work in 2024 suggests ongoing commitment to maintaining the building's structural components, particularly those related to the hilly terrain of the Castro neighborhood.
