Initial analysis

The property at 309-311 Clement Street in the Inner Richmond neighborhood is a two-story, multi-family residential building with commercial space, containing two units and constructed in 1900, currently owned by David Wong Separate Property Trust. The building's maintenance and improvement history shows attention to safety and accessibility, with significant recent work including a 2022 electrical upgrade (replacement of sub panel with new 200 amp panel) and sewer repair, and a 2022 complaint regarding unpermitted awning installation that has since been resolved through the awning amnesty program completed in 2024. Historical improvements include handicap accessibility upgrades in 2007, a voluntary fire safety system installation in 2014, and various utility and maintenance work.

The property has experienced some infrastructure challenges, as evidenced by recent 2025 incidents involving sewage discharge and human waste concerns near the property, though these were not directly related to the building itself. There have been multiple complaints about illegal parking in the vicinity throughout 2024, some resulting in citations, and several shared spaces-related fire complaints between 2022 and 2025, most of which were found to have no merit or were promptly addressed. The building's permit history includes both completed and expired permits for various improvements, including commercial kitchen equipment modifications in 1987, roofing work in 1993, and sidewalk modifications in 2003, indicating ongoing maintenance and compliance with building regulations over the years.

Risk rating

How 309-311 Clement 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.

Neighborhood percentile

Out of 1723 buildings in this neighborhood, 1241 are predicted to be safer.
