Initial analysis

The 4-unit multi-family residential building at 441 4th Avenue in the Inner Richmond, owned by the Ruan/hu Family Trust, was constructed in 1907 and is two stories tall. The most significant recent improvement was completed in 2008, encompassing a comprehensive renovation of unit #3 that included bathroom fixture replacements, exhaust fan installation, kitchen renovations, and the conversion of single-pane aluminum windows to vinyl, along with corresponding electrical and plumbing updates totaling $17,000. This work included the installation of new bathroom and kitchen circuits, multiple receptacles, and associated plumbing fixtures, all of which were completed successfully.

The building has undergone three routine safety inspections by Housing Inspection Services in 2001, 2006, and 2016, with all identified violations being promptly addressed and abated. Notable violations from these inspections included items related to fire safety (fire extinguisher maintenance and CO alarm installation), door security requirements, and gas utility shutoff tools. All these issues were resolved, with the most recent inspection occurring in 2016 showing active compliance. The property has experienced minimal emergency incidents, with only one documented emergency medical service call and no civilian injuries recorded. Recent activity at the address has primarily consisted of routine municipal matters such as street cleaning and parking enforcement, with several parking-related incidents being addressed between 2018 and 2023. The last recorded building permit was from 1990 for reroofing work, though this permit has since expired.

Risk rating

How 441 4Th 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.
