Initial analysis

The property at 211 6th Avenue in San Francisco's Inner Richmond neighborhood is a 2-story, 3-unit multi-family residential building constructed in 1900, currently owned by Ronald B. and Irene S. Wong Trusts. The building has undergone several significant repairs and maintenance work over the past decade, including a $17,000 re-roofing project completed in 2011, replacement of a heating fan-coil unit in 2014, and repair of exterior stairs and handrails in 2010. The property has faced multiple building code violations, notably in 2004 and 2010, addressing issues with stairs, fire safety concerns, lead paint hazards, and exit accessibility, though all these violations were ultimately abated. A routine housing inspection was conducted in 2015, though no active violations were recorded from this inspection.

More recently, there was a sewage backup issue reported in October 2023 that was promptly resolved by the Public Utilities Commission. The property has been the subject of multiple 311 calls between 2018 and 2022, primarily regarding street and sidewalk cleaning needs, with several reports of loose garbage in the vicinity, though these exterior maintenance issues are not directly related to the building's habitability. A comprehensive review of the building's history shows a pattern of addressing maintenance issues as they arise, with most violations and complaints being resolved within reasonable timeframes. The building's most recent significant maintenance work included addressing sewage system issues in 2023, which was resolved by city services.

Risk rating

How 211 6Th 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

Out of 1723 buildings in this neighborhood, 1051 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 75.2%
Moderate concern 19.5%
Severe concern 5.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
