Initial analysis

The property at 2121-2127 Fillmore St is a three-story, 19-unit multi-family residential building constructed in 1900, currently owned by Tony C & Lily C Dong 94 Trust. The building has undergone several significant improvements and faced various compliance issues over the past several years. Most recently, in October 2023, the property filed permits for ADA compliance updates to the storefront, including new door hardware and power door operators, following previous storefront compliance check requirements from 2018. The building completed its mandatory soft-story retrofit work and received its Certificate of Final Completion (CFC) as a Tier 4 building. Notable recent maintenance includes the installation of fire service and bypass backflow devices in 2022, and significant apartment renovations in 2019 including kitchen and bathroom remodels in multiple units (Apts 1, 11, and 15).

The building's history includes some concerning issues that have required attention. In 2019, there was a violation regarding an unpermitted boiler operation that was eventually resolved. More recently, in 2022, there is an active complaint regarding an unpermitted "KNIX" sign on the building. The property has experienced several fire safety-related complaints over the years, including issues with alarm systems, sprinkler systems, and blocked exits, though all were marked as "Condition Corrected" upon follow-up inspections. Maintenance records indicate regular updates to infrastructure, including the replacement of water heaters with a hot water boiler in 2018, and multiple plumbing and electrical improvements throughout the building's history. The property has also faced periodic challenges with exterior maintenance, as evidenced by numerous 311 calls regarding garbage and debris on the surrounding property, particularly in recent months (2024).

Risk rating

How 2121-2127 Fillmore 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.
