Initial analysis

The two-unit residential building at 472 Corbett Avenue in Clarendon Heights is a two-story flats and duplex structure built in 1948, currently owned by the Karsant-mourelatos Family Trust. The building has undergone several significant improvements in recent years, most notably a comprehensive kitchen and bathroom renovation completed in 2016, which included new cabinets, tile work, and electrical updates such as ceiling lights in the living room and preparations for future remodeling of the neighboring unit at 474 Corbett Avenue. This renovation project, valued at $40,000, was accompanied by proper plumbing and electrical permits and was successfully completed. The property's electrical infrastructure received an upgrade in 2005 with the conversion from overhead to underground service.

The building's maintenance history includes a reroofing project completed in 1999, though this permit has since expired. The property has experienced several external issues in recent years, particularly related to street cleaning and parking violations. Between 2018 and 2024, there were multiple reports of garbage and debris on the street and sidewalk, with the most recent being a glass-related issue in December 2024 that was deemed not requiring further action. The area has also experienced recurring issues with illegal parking, particularly on sidewalks, with multiple reports between 2018 and 2021, though in each case, responding officers were unable to locate the offending vehicles. While these external environmental and parking issues have been documented through 311 calls, they primarily relate to the immediate neighborhood rather than the building's structural or safety features.

Risk rating

How 472 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
90th percentile

Out of 40 buildings in this neighborhood, 4 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.

Neighborhood location

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

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 82.0%
Moderate concern 12.1%
Severe concern 5.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
