In 2022, a Boise-area contractor named Matthew Riffey became the focus of criminal charges after multiple Idaho homeowners reported paying substantial deposits for construction and remodeling work that was either never started or left abandoned partway through. Prosecutors charged Riffey with grand theft and diversion of construction funds, a felony under Idaho law that targets contractors who accept money designated for a specific building project and then use it for other purposes.
The case reflects a recurring pattern in residential construction fraud: homeowners hand over large upfront payments in good faith, the contractor collects from several clients at once, and the money disappears into personal expenses or the debts of earlier jobs. When the work stalls, homeowners are left with unfinished structures, out-of-pocket losses, and little practical recourse beyond a slow civil or criminal process.
What Happened
According to reporting on the case and charging documents referenced in local coverage, Riffey solicited deposits from homeowners for new home builds and remodeling projects in the Boise metro area. The deposits were substantial—often tens of thousands of dollars—reflecting the cost of materials and initial labor for large residential jobs.
In several instances, homeowners said work never meaningfully began, or that projects were abandoned after early demolition or framing left their properties in worse condition than before. When clients pressed for progress or refunds, communication reportedly broke down. The accumulation of complaints from multiple households prompted law enforcement involvement and, ultimately, felony charges including grand theft and the specialized charge of diversion of construction funds.
Idaho's diversion of construction funds statute exists precisely because of this scenario. Under the law, money a contractor receives for a specific project is meant to pay for the labor and materials of that project. Using it for unrelated purposes—paying off a previous client, covering personal debts, or funding an entirely different job—can constitute a crime even if the contractor intended to eventually finish the work.
Why the Fraud Was Easy to Commit
Residential construction is structurally vulnerable to this kind of loss for a simple reason: the money moves before the work does. Custom construction typically requires a homeowner to pay a deposit and progress payments in advance so the contractor can buy materials and mobilize crews. That timing creates a window in which the contractor controls the client's cash but has delivered little or nothing in return.
Unlike a real estate closing or a regulated financial transaction, a typical home-improvement contract places the deposit directly into the contractor's own bank account. There is no neutral party verifying that the money is spent on the intended project. A contractor juggling multiple jobs can use one client's deposit to finish another client's work—a practice sometimes described as 'robbing Peter to pay Paul'—until the cycle collapses and the last several customers are left with nothing.
Idaho also has relatively light contractor oversight. The state requires registration of construction contractors but does not impose a rigorous bonding or trust-account requirement comparable to some other states. That regulatory gap makes it easier for problems to escalate before authorities or homeowners can intervene.

What the Investigation Found
Investigators reviewing the Riffey matter focused on the pattern that distinguishes a business failure from a crime: multiple victims, funds collected for named projects, and money that could not be accounted for as project spending. The diversion of construction funds charge signals that prosecutors believed deposits were used for something other than the homes they were meant to build.
Cases like this are difficult for individual homeowners to pursue alone. A single unfinished project can look like a contract dispute, but when several households come forward with similar experiences, prosecutors can build a stronger criminal case. Even so, criminal charges rarely make victims whole. Restitution orders depend on a defendant having assets to repay, and by the time charges are filed, the money has usually been spent.

What Escrow Would Have Changed
The defining weakness in cases like Riffey's is that the homeowner's money and the contractor's control are combined too early. Escrow directly addresses that flaw. In an escrow arrangement, a homeowner's deposit is held by a neutral third party rather than deposited into the contractor's account. Funds are released only when defined milestones are verified—foundation poured, framing complete, rough-in inspected.
This structure makes diversion nearly impossible. A contractor cannot use one client's deposit to pay for another client's job because the money is not in the contractor's hands to move. If work stalls, the undisbursed balance remains with the escrow agent and can be returned to the homeowner rather than vanishing.
Milestone-based escrow also aligns payment with progress. Instead of paying a large lump sum upfront and hoping for delivery, the homeowner pays for value already received and verified. Had Riffey's clients placed their deposits into escrow with milestone verification, the abandoned projects would have left most of their money protected and recoverable—turning a potential total loss into a manageable delay. Escrow does not guarantee a contractor performs, but it removes the incentive and the opportunity for the specific crime Idaho charged: diverting construction funds away from the projects they were meant to build.
