Initial analysis

The three-unit, three-story apartment building at 475-477 Green Street in Telegraph Hill, owned by the Chang Tan Family Trust, was constructed in 1906 and has undergone several significant safety-related improvements over the years. Most notably, the building participated in San Francisco's mandatory Soft Story Retrofit Program, classified as Tier 3. Recent permits show work was completed in 2023-2024, including footing additions and final inspections, with a Certificate of Final Completion (CFC) issued, indicating compliance with seismic safety requirements.

The building's recent history includes a fire safety incident in July 2024 involving blocked exits, though this was promptly corrected within six days. An active violation from May 2020 related to the Soft Story program has been resolved with the completion of retrofit work. Previous violations from 2013-2014 regarding soft story compliance and lead paint concerns were abated in 2013. The property has maintained regular maintenance records, including a termite treatment in 2004 and re-roofing work in 2000. Recent 311 calls (September-December 2024) primarily relate to parking violations on the sidewalk, with a total of ten such complaints filed, though enforcement officers were often unable to locate the vehicles in question.

Risk rating

How 475-477 Green 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
