Initial analysis

The property at 725 21st Avenue in the Central Richmond neighborhood is a 2-story, 3-unit multi-family residential building constructed in 1950, currently owned by Aleksandr & Mera Goldyak. The building's maintenance history shows several improvement efforts, including the installation of aluminum windows in 1986-1987 and vinyl siding application in 2002, though the latter permit has since expired. The building has experienced multiple safety-related violations over the years, most notably in 2002 and 2011, including issues with fire safety equipment such as fire extinguishers and smoke detection systems, all of which were eventually abated. A concerning complaint was filed in October 2021 regarding the in-law unit at the rear of the building, documenting multiple issues including lack of heat, hazardous electrical outlets, water intrusion, and concerns about illegal unit status.

The building's recent history includes several 311 calls regarding various issues, including noise complaints in 2018 and 2019, and a street cleaning matter in January 2021. While the cited violations and complaints have been addressed according to official records, the pattern of safety-related issues, particularly regarding smoke detection and fire safety equipment, is notable. The most recent significant concerns from 2021 regarding the rear unit's habitability and safety systems stand out as the current property's most troubling feature, though these were filed more than two years ago and their resolution status is not immediately clear from the available data.

Risk rating

How 725 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.

Neighborhood percentile
