Initial analysis

The 5-unit, 2-story apartment building at 1623-1625 Noriega Street, owned by the Tsang Family Trust, was constructed in 1960 and has undergone several maintenance and improvement projects over the years. Historical records show modifications including a garage conversion to office space in 1993, kitchen renovations in 2000, and various window repairs. The building has experienced recurring fire safety issues, particularly notable in recent years, with violations and complaints regarding fire escape ladders, fire extinguishers, and sprinkler systems between 2020 and 2024. Most recently, there was a sleeping area requirements violation issued in October 2023 that remains open.

In 2021, significant safety concerns were raised during routine inspections, including issues with window hardware, carbon monoxide and smoke alarm compliance, and fire escape functionality. An active complaint from October 2021 remains unresolved regarding ventilation and window functionality in Apartment 4. The building has experienced multiple fire system-related complaints since 2020, with most being corrected promptly, though the most recent sleeping area violation from October 2023 is still pending resolution. While the building has undergone various improvements, including a street space permit issuance in 2011, the concentration of recent violations related to fire safety systems and building maintenance suggests ongoing maintenance challenges. The property has also generated multiple 311 calls in 2024, primarily related to street cleaning issues, though these are external to the building itself.

Risk rating

How 1623-1625 Noriega 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.
