Initial analysis

The four-unit, four-story multi-family residential building at 465-471 Corbett Avenue in Clarendon Heights, constructed in 1908, has experienced several significant maintenance and safety issues over the past two decades. The property has faced recurring problems with building safety and habitability, including multiple housing code violations. Most notably, in 2011-2012, there were serious concerns regarding the building's condition, including reports of major vermin infestations (including raccoons and rats), a gas issue on the second floor, and multiple building violations requiring repairs to ceilings, stairs, handrails, and security glazing on doors. The property has undergone several rounds of repairs in response to housing violations, including stair repairs in 2012 and various improvements in 2006 such as vinyl siding installation and other corrective work to address housing inspector citations. Electrical improvements were completed in 2011, including the installation of new outlets and circuits. The building's maintenance history also shows evidence of moisture-related issues, with complaints about mold in bedrooms recorded in 2009, and exterior maintenance concerns including high weeds and debris reported in multiple years. Recent activity at the property has primarily consisted of routine matters, such as waste management and parking enforcement issues, with the most recent building-related concern being a parking violation reported in February 2024. The building's long-term maintenance record suggests periods of neglected upkeep followed by concentrated remediation efforts in response to violations, though more recent years show fewer documented major violations or complaints related directly to the building's condition.

Risk rating

How 465-471 Corbett 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 40 buildings in this neighborhood, 16 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

12-Month severity forecast
No violation 74.7%
Moderate concern 13.1%
Severe concern 12.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
