Initial analysis

The property at 305-311 6th Avenue in San Francisco's Inner Richmond district is a two-story mixed-use building constructed in 1900, containing 6 multi-family residential units and ground-floor commercial space. The building has undergone several significant maintenance and improvement projects over the past two decades, including a major reroofing project in 2008 ($32,500), interior renovations in 2010 (tile and ceiling replacements), and the removal of an exterior wooden utility ladder in 2014, which had been the subject of a building violation due to safety code violations. A sewer line repair was conducted in 2020, representing the most recent significant infrastructure work on record.

The building has experienced some regulatory scrutiny, including a 1997 conversion of the entrance to handicap accessibility, and a 2007 incident involving an unauthorized sign installation that extended over the public sidewalk. More recently, there have been multiple 311 calls between November 2024 and January 2025, primarily regarding street-related issues such as lighting, garbage, and sidewalk maintenance, though these are generally related to public infrastructure rather than building-specific concerns. Planning records indicate some historical issues with unauthorized dental office use on the second floor and improper signage, though these matters were ultimately resolved and abated. The current ownership by Chun Family Living Trust is noted, though the building's maintenance history suggests regular upkeep and prompt addressing of safety violations when they arise.

Risk rating

How 305-311 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
24th percentile

Out of 1723 buildings in this neighborhood, 1309 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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

12-Month severity forecast
No violation 57.3%
Moderate concern 23.3%
Severe concern 19.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
