1400-1404 Hyde St, San Francisco, CA 94109

The 6-unit residential building at 1400-1404 Hyde Street in Nob Hill, owned by Mary Yang Family LLC, is a 3-story structure built in 1909 that has undergone significant structural improvements in recent years. The building completed its mandatory soft-story retrofit program as a Tier 4 property, with all work associated with commercial and residential seismic retrofits being officially completed and receiving Certificates of Final Completion.

A notable addition was made to the property in 2022, with the construction of an ADU unit comprising 675 square feet with 2 bedrooms, an office, kitchen, and bathrooms, along with necessary electrical and plumbing installations, though these permits have since expired. Recent concerns about the property have emerged in 2023 and 2024, including active complaints regarding unauthorized work and potential illegal demolition, as well as issues with an unpermitted sign installation. The building's maintenance history shows various routine inspections and violations being addressed over time, including historical problems such as heating issues, water leaks, and safety concerns noted as far back as the 1990s.

The property has experienced approximately five sewer-related incidents on the adjoining street in 2024, though these were external to the building itself. While some previous violations from 2008 regarding lead paint and multiple safety concerns were documented, these issues were marked as abated by December 2023, suggesting compliance with housing safety requirements. Additionally, multiple reports of abandoned furniture and debris have been documented on the property in 2024, indicating ongoing maintenance challenges.
