Initial analysis

The 7-unit, 3-story multi-family residential building at 229 21st Avenue in the Central Richmond neighborhood, owned by Tatiana V Hall 2018 Revoc L, has undergone several significant improvements since its construction in 1922. Most notably, the building completed a comprehensive fire alarm system upgrade in 2021 costing $14,000, which included the installation of smoke detectors, horn strobes, and other safety components to comply with current fire codes. In 2015, the building underwent important seismic improvements, including a mandated Tier 3 soft-story retrofit and water heater reinstallation, demonstrating compliance with modern safety standards. The property has a documented history of fire safety violations from 2003-2006, including issues with fire escape ladders, fire extinguishers, and smoke detection systems, though all these violations were resolved by November 2006.

Recent maintenance records show regular upkeep of the building, including a complete reroofing project in 2018 ($25,000) and window replacements in 1998. The building has passing routine housing inspections, with only one active routine inspection recorded in 2014. While there have been multiple reports of garbage and debris issues (2023-2024) around the property, none of these directly relate to building maintenance or safety concerns. The property appears to be actively maintained, with significant investments in both structural safety (seismic retrofit) and fire safety (modern fire alarm system), though regular inspections and reported maintenance issues suggest ongoing attention to building upkeep.

Risk rating

How 229 21St 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.
