The Idaho Supreme Court recently ruled against Samuel Lee Services LLC (SLS), a Montana-based contractor, in a case concerning payment for mold remediation services. The court's decision, issued on October 20, 2026, confirmed that SLS could not pursue its claim against homeowner Heather Bangeman due to SLS's failure to register as a contractor under the Idaho Contractor Registration Act (ICRA). This ruling has implications for contractors operating in Idaho, particularly those who are not registered.

The case began when SLS provided mold remediation services to Bangeman's home in Bonner County, Idaho, but later sought payment of $44,451.36 for the work performed. Bangeman, however, refused to pay SLS, claiming that the contractor had not properly completed the remediation work and that she had already received payment from her insurance company for the same services. The dispute escalated when SLS filed a complaint against Bangeman for unjust enrichment, seeking to recover the costs of the services rendered.

In her defense, Bangeman moved to dismiss the complaint, arguing that ICRA barred SLS from bringing a legal action since it was not a registered contractor in Idaho. SLS did not dispute its lack of registration but contended that an equitable exception should apply, allowing them to recover the payment. The district court agreed with Bangeman, dismissing SLS's complaint and stating that the ICRA unambiguously precluded unregistered contractors from filing claims in Idaho courts.

The Idaho Supreme Court upheld the district court's decision, affirming that the plain language of ICRA prohibits unregistered contractors from seeking compensation for work performed. The court noted, "ICRA unambiguously precludes SLS’ claim, and no equitable exception applies to the general rule that illegal contracts are unenforceable." This ruling highlights the importance of compliance with registration requirements for contractors in Idaho.

The court's opinion emphasized that while SLS acted in good faith and provided services under exigent circumstances, the law does not allow for exceptions to the registration requirement. The court stated, "We are sympathetic to SLS’ plight... However, these facts do not permit us to ignore the unambiguous language of ICRA." This ruling reinforces the idea that the legislature's intent in requiring contractor registration is to protect the public from unqualified or dishonest contractors.

The implications of this ruling are significant for contractors operating in Idaho. It underscores the necessity for contractors to be registered before engaging in work that requires a license. Failure to comply with this requirement can result in the inability to recover payment for services rendered, regardless of the circumstances surrounding the work. This decision may serve as a cautionary tale for other contractors who may consider working in Idaho without proper registration.

Moving forward, contractors must ensure they are registered under ICRA before undertaking any work in Idaho to avoid similar legal challenges. The ruling also clarifies that even if a contractor performs work in good faith, it does not exempt them from the legal requirements set forth by state law.

As for what’s next, SLS could potentially seek further legal avenues, although the court's ruling appears to leave little room for appeal given the clear statutory language of ICRA. The court also noted that Bangeman is not entitled to attorney fees on appeal, as SLS raised legitimate arguments regarding the application of equitable exceptions. This case serves as a reminder of the importance of adhering to licensing laws in the construction industry and the potential consequences of operating outside those regulations.
