Initial analysis

The 6-unit, 3-story multi-family residential building at 414-424 3rd Avenue in the Inner Richmond, owned by Won Ji Hyung, has experienced numerous significant maintenance and safety concerns, particularly in recent years. Most pressing are current active complaints from 2024 regarding heat issues, including non-functional heaters and stoves, as well as concerns about mold, electrical work, and emergency exit obstructions. The building's soft-story retrofit status is currently listed as non-compliant under Tier 3 requirements, with a complaint filed in 2021 regarding incomplete permit inspections, though multiple permits for soft-story retrofit work were issued in 2018 with a $30,000 value. Historical violations from 2000 included multiple safety concerns that were eventually abated in 2003, such as issues with fire extinguishers, stairs, handrails, and security features.

The property has a pattern of heating and infrastructure issues, with complaints about no hot water (2016), low water pressure and rusty pipes (2015), and various heating system failures. Recent 311 calls (2024) have documented ongoing problems with garbage and debris, including reports of blocking fire exit routes, though some issues have been resolved. The building has experienced multiple fire-related concerns, primarily involving combustible materials, with the most recent violation issued in 2024. While some historical issues have been resolved or corrected, including various repairs made in 2001 (rear yard stairs) and 2005 (gas heater installation), the pattern of recent complaints suggests ongoing maintenance challenges.

Risk rating

How 414-424 3Rd Ave'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.
