The three-story multi-family residential building at 1633-1639 Washington Street in Nob Hill, owned by the Peter I Iskandar Revocable Trust, was constructed in 1907 and contains 6 units. The property has undergone significant recent improvements to its safety systems, including a completed fire alarm system upgrade in August 2023 to comply with current codes, and the installation of low-frequency sounders in sleeping areas.

In 2020-2021, substantial renovations were carried out including bathroom remodels, door replacements, and flooring updates in multiple units, along with mechanical upgrades such as new furnaces, water heaters, and an upgraded electrical service to 400A with 10 meters. The building has a notable history of addressing safety and compliance issues, including a routine inspection in 2011 that identified several violations (now resolved) related to fire safety, seismic bracing, and security requirements. In 2018, there were significant complaints regarding structural issues, including reports of wall and ceiling problems, door operation issues, and concerns about retrofitting practices, though these were marked as not active.

The property has also undergone important infrastructure improvements, including the addition of three accessory dwelling units (ADUs) in 2018-2019, with full bathrooms and kitchens installed in each. The building is classified as Tier 4 for soft-story compliance, with work completed and a Certificate of Final Completion (CFC) issued.
