Initial analysis

The two-unit residential building at 406-408 Andover Street in Bernal Heights, owned by Cinthia A. Velez, is a two-story flats and duplex structure built in 1907. The building's maintenance record shows several significant structural improvements over the past quarter-century. Most notably, in 2008, a major foundation replacement project was undertaken, involving the installation of a new concrete foundation to replace the existing brick one, with an investment of $50,000; this work received final inspection approval in 2012. Other permitted work includes a withdrawn application from 2001 for a bedroom addition at the rear of the building, and an expired permit from 1998 for reroofing work.

The building has experienced minimal tenant complaints, with only one recorded incident in January 1998 involving water intrusion from the adjacent unit at 410 Andover, though this issue was promptly addressed within a week of being reported. Given the age of the building and the nature of the foundation work completed, it appears that significant structural improvements have been made, particularly in terms of foundation stability. The most recent permitted work was completed over a decade ago, and there have been no major complaints or incidents reported in the past 25 years, suggesting a period of relative stability in recent years.

Risk rating

How 406-408 Andover 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.
