Idaho Supreme Court Revives Home Build Lawsuit

Live Poll

If a contractor skipped licensing, should you still be able to sue them?

The Idaho Supreme Court reinstated a breach-of-contract lawsuit brought by Elk River homeowners against an Idaho construction company that was unregistered when it signed their wooden-frame house contract. The court reversed a district court dismissal and sent the case back for further proceedings.

Why it matters

The decision clarifies that Idaho law bars an unregistered contractor from recovering payment, but does not extend that bar to homeowners, who may still pursue a remedy. The court said a contrary reading could leave harmed homeowners without recourse, undermining the licensing law's consumer protection purpose.

The homeowners paid $305,033.57 to the contractor, while an independent April 2024 estimate put repair and completion costs at $331,034.30. The total damages sought and the outcome of the remanded claims remain undetermined.

The players

Idaho Supreme Court

The state's highest court, which reviewed the district court's ruling and held that contracts with unregistered contractors are voidable at the homeowner's option.

The details

The homeowners hired the company in July 2021 to build a wooden-frame house in Elk River, Idaho, and made payments through several invoices. The district court had ruled the agreement void because the company was unregistered when it was signed and dismissed the homeowners' claims, a reasoning the Idaho Supreme Court rejected by treating such contracts as voidable at the homeowner's option.

April 11, 2021: the construction company's contractor registration expired.
July 2021: the homeowners hired the company to build the house.
August 2021 to January 2022: the homeowners paid $305,033.57 in invoices.
October 22, 2021: the company's contractor registration was reinstated.
November 12, 2026: the Idaho Supreme Court issued its ruling.

Legal Context

The ruling interprets Idaho's contractor registration requirement as a consumer protection rule that restricts unregistered builders from collecting payment, not homeowners from enforcing their contracts. It reverses a lower court approach that had treated such agreements as void for both parties.

Homeowners considering a build or major renovation in Idaho should confirm a contractor's state registration before signing and paying. Under the ruling, a homeowner may still have a path to recover losses from an unregistered builder, but verifying registration up front avoids the cost of a lengthy dispute.

The takeaway

Checking a contractor's registration before signing a home-building contract can prevent costly disputes over payments and repairs. Homeowners should keep detailed records of every invoice and payment in case a project stalls.
