Initial analysis

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.

Risk rating

How 1400-1404 Hyde St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
