Initial analysis

The 11-unit, 3-story apartment building at 483-489 14th St in Mission Dolores, owned by Weng Tony Chai-chy, was constructed in 1927 and has undergone several significant safety improvements over the past decade. The building completed a mandatory soft-story retrofit of the ground floor in 2014, and most recently updated its fire alarm system in 2022-2023, including new smoke detectors, pull stations, and monitoring equipment. A comprehensive evaluation of the building's history reveals several concerning patterns, particularly in the early 2000s, when multiple housing violations were documented, including issues with fire escapes, heating systems, and interior maintenance in Unit #2. Though these violations were resolved by 2008, they indicate a period of significant maintenance challenges.

In recent years, the building has shown improved compliance with safety regulations, as evidenced by the completion of the soft-story retrofit (Tier 4) and the recent fire safety upgrades. A series of fire safety inspections in 2019-2020 yielded "No Merit" findings for multiple potential hazards, including blocked exits, fire escapes, and alarm systems. The property has experienced some recurring issues with exterior maintenance, as shown by multiple 311 calls regarding graffiti and debris between 2024-2025. While the building's recent history is marked by fewer serious violations, the clustering of illegal construction complaints and various maintenance issues in the 2000s suggests that continuing attention to building systems and maintenance standards is warranted. The most recent building inspection in 2023 regarding common areas was addressed and marked as "Not Active."

Risk rating

How 483-489 14Th 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.
