Initial analysis

The 6-unit multi-family residential building at 183-185 Duboce Avenue, owned by the Ruan/hu Family Trust, was constructed in 1906 and is three stories tall.

In 2007, the building underwent significant renovations including kitchen remodels in multiple units (#183, #183A, #183B, and #185) and window replacements, which initially generated complaints about potential unpermitted work and asbestos concerns. The building has a history of water-related issues, with complaints about leaks in 2017 and a more serious set of violations in 2004 involving faulty electrical wiring, roof leaks, plumbing problems, and evidence of dry rot and mold. Infrastructure improvements include plumbing upgrades in 2008 comprising new gas lines, sink drainage, water pipes, and installation of six 30-gallon electric water heaters, along with electrical upgrades including new circuits, subpanels, and switchboards. The property has had various maintenance issues documented through 311 calls, including sidewalk defects, graffiti, and waste removal requests.

Risk rating

How 183-185 Duboce 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.
