Never-Registered Contractors Cannot Use Unjust Enrichment to Recover from Idaho Homeowners

A. Procedural Posture and Standard of Review

Bangeman initially moved to dismiss under Idaho Rule of Civil Procedure 12(b)(6). SLS opposed that motion with a declaration from Ashcraft. Because the district court considered material outside the pleadings, it treated the motion as one for summary judgment and dismissed the complaint on that basis.

Relying on Paslay v. A&B Irrigation Dist., 162 Idaho 866, 406 P.3d 878 (2017), the Supreme Court reviewed the summary judgment decision de novo. Under Idaho Rule of Civil Procedure 56(a), summary judgment is appropriate when no genuine issue of material fact exists and the moving party is entitled to judgment as a matter of law.

The district court’s analysis had two steps: ICRA prohibited SLS’s action, and no equitable exception overcame that prohibition. SLS challenged only the second step on appeal. This confined the Supreme Court’s inquiry to the availability of equitable relief rather than requiring a fresh determination of statutory coverage.

The parties’ disagreements about workmanship, disclosure, and insurance proceeds did not require resolution because they did not change the dispositive circumstances: SLS never registered, and it sought compensation from the homeowner for whom it performed the work.

B. Precedents Cited and Their Influence

Genho v. Riverdale Hot Springs, LLC

Genho v. Riverdale Hot Springs, LLC, 174 Idaho 894, 560 P.3d 1041 (2024), supplied the Court’s most recent explanation of equitable recovery under ICRA. It concerned a contractor that became registered during a construction project. The property owner argued that recovery should be unavailable unless the contractor had been registered throughout the entire project.

Genho rejected that all-or-nothing position. A contractor may pursue equitable remedies for work performed after registration when that work is severable from the earlier, unregistered work. The rule balances registration requirements against the risk that an owner might exploit a contractor that subsequently complied with the law.

SLS relied on this discussion of competing public interests. The Court held that SLS overlooked the essential limit: the permitted recovery concerned post-registration work. The discussion of exploitation did not create an independent exception for any contractor facing nonpayment. Because SLS never registered, none of its work fell within the protected category.

ParkWest Homes LLC v. Barnson

ParkWest Homes LLC v. Barnson, 149 Idaho 603, 238 P.3d 203 (2010), appeared through the Court’s discussion and quotation of Genho. It provided the foundation for allowing equitable remedies when registration occurs during a project and subsequent work can be separated from unregistered work.

Its significance is that registration has prospective consequences without retroactively validating earlier illegality. As the quoted discussion emphasized, illegal contracts remain unenforceable, and liens may not rest on pre-registration work. The recognized accommodation therefore rewards lawful subsequent performance rather than excusing earlier noncompliance.

Farrell v. Whiteman

Farrell v. Whiteman, 146 Idaho 604, 200 P.3d 1153 (2009), involved an out-of-state architect who began work on an Idaho condominium project before obtaining the license required by Idaho’s Architecture Practice Act. The architect obtained an Idaho license during the project and later sued after the developer terminated the relationship.

The Court held that the architect’s unlicensed work was illegal but could be separated from work performed after licensure. An equitable claim for quantum meruit could therefore address the value of the later, lawful services.

In the present case, Farrell reinforced the distinction between unlawful and lawful performance. It did not establish a general right to payment whenever nonpayment appeared inequitable. SLS had no comparable period of lawful, post-registration performance.

AED, Inc. v. KDC Investments, LLC

AED, Inc. v. KDC Investments, LLC, 155 Idaho 159, 307 P.3d 176 (2013), addressed whether registration obtained after entering a contract could transform an illegal agreement into a legal one. The Court held that it could not.

That decision nevertheless repeated Farrell’s qualification: severable services performed after registration might support equitable remedies. The contractor in AED, Inc. could not recover under unjust enrichment because it had performed no services before termination of the contract.

The present opinion uses this precedent to distinguish contract validity from restitution for subsequent lawful services. Later registration does not validate the original illegal contract, but qualifying later performance may have an independent equitable basis for recovery. Neither proposition assists a contractor that never registers.

Barry v. Pacific West Construction, Inc.

Barry v. Pacific West Construction, Inc., 140 Idaho 827, 103 P.3d 440 (2004), concerned an unregistered subcontractor’s claims against a general contractor arising from a public works project. The applicable statute was the Public Works Contracting License Act (“PWCLA”), which, like ICRA, contains registration or licensing requirements and a restriction on actions to recover compensation.

The Court in Barry held the contract illegal and unavailable as a basis for recovery. It nevertheless remanded for further consideration of unjust enrichment, recognizing that denying all relief can sometimes frustrate the public interest more than permitting an equitable claim. The remand did not itself establish an entitlement to payment.

The present opinion identifies the decisive distinction: Barry involved a dispute between construction professionals, not a claim against the public beneficiary of the protective statute. The State was not a party and had not sought to withhold payment because of the subcontractor’s registration failure.

By contrast, SLS sued a homeowner receiving construction services—the very person ICRA seeks to protect. The reasoning that supported further consideration of equity in Barry therefore did not apply.

McFall v. Arkoosh and Gene Taylor & Sons Plumbing Co. v. Corondolet Realty Tr.

McFall v. Arkoosh, 37 Idaho 243, 215 P. 978 (1923), supplied the public-policy principle quoted in Barry: the general rule against relief under illegal contracts may yield when granting relief better promotes the public interest. The present Court did not reject that principle; it rejected SLS’s proposed application of it against a protected homeowner.

Gene Taylor & Sons Plumbing Co. v. Corondolet Realty Tr., 611 S.W.2d 572 (Tenn. 1981), was the Tennessee authority favorably quoted in Barry. Its relevant reasoning distinguished recovery against members of the public from disputes against licensed professionals in the same business. That distinction helped explain why Barry was not controlling here.

Trees v. Kersey

Trees v. Kersey, 138 Idaho 3, 56 P.3d 765 (2002), involved joint venturers pursuing public works projects. One participant was registered under PWCLA and submitted bids; the other was unregistered and performed the work. After their relationship deteriorated, the unregistered participant asserted several claims, including fraud.

Although the venture agreement was illegal, the Court declined to apply the illegality doctrine strictly to bar the fraud claim. The parties owed each other fiduciary duties, and the alleged wrongdoing concerned their internal relationship rather than dealings with the general public.

The present opinion distinguishes Trees on both relational and substantive grounds. SLS’s claim sought compensation from a homeowner, not redress for fraud between fiduciaries. The case therefore could not supply a general permission to recover payment for unregistered construction services.

Sedco Int'l[] v. Cory

Sedco Int'l[] v. Cory, 522 F. Supp. 254 (1981), appeared in SLS’s quoted argument through Trees. It supplied the formulation that the central inquiry is whether granting relief would further or defeat the law’s purposes. The Supreme Court did not separately analyze its facts or adopt it as an independent basis for recovery. Instead, the Court evaluated the purposes of ICRA and concluded that permitting this homeowner-directed claim would conflict with them.

Authorities Governing Appellate Attorney Fees

Rudd v. Merritt, 138 Idaho 526, 66 P.3d 230 (2003), supplied the standard under Idaho Code section 12-121: appellate fees may be awarded when the Court has an abiding belief that the appeal was pursued frivolously, unreasonably, or without foundation.

City of Boise v. Ada County, 147 Idaho 794, 215 P.3d 514 (2009), quoting Nelson v. Nelson, 144 Idaho 710, 170 P.3d 375 (2007), supplied the complementary principle that fees generally are inappropriate when an unsuccessful appeal is brought in good faith and presents a genuine legal issue.

These authorities allowed the Court to distinguish an unsuccessful legal argument from a sanction-worthy appeal. SLS’s interpretation of the equitable precedents failed, but its arguments were sufficiently substantial to defeat Bangeman’s fee request.

C. Legal Reasoning

1. Equity Cannot Simply Displace the Statutory Bar

The Court treated Idaho Code section 54-5217(2) as an unambiguous restriction on an unregistered contractor’s ability to sue for compensation. SLS’s choice of unjust enrichment did not alter the substance of the action: it sought payment for construction services performed without registration.

This is the opinion’s central doctrinal point. An equitable claim is not automatically available whenever contractual recovery is prohibited. Otherwise, the statutory restriction could routinely be avoided by changing the complaint’s label.

2. Earlier Exceptions Turned on Legality and Statutory Purpose, Not Hardship Alone

The Court organized the precedents around two distinctions. First, the post-registration cases permitted recovery only for separable services performed after compliance. Second, the public-works cases involved disputes among professionals or joint venturers rather than claims against the public whom the legislation protected.

SLS satisfied neither condition. It never registered, and its defendant was the homeowner receiving its services. The alleged unfairness of nonpayment did not erase those differences.

3. The Homeowner’s Protected Status Was Central

Idaho Code section 54-5202 links construction regulation to public health, safety, and welfare and identifies the public interest in removing incompetent, dishonest, or unprincipled practitioners from practice. The Court relied on that legislative purpose to explain why allowing SLS’s claim would undermine rather than advance the statutory scheme.

The opinion does not establish that every dispute between construction professionals escapes ICRA. It holds more narrowly that precedents arising in different professional relationships did not justify an exception in this homeowner case.

4. Sympathetic Circumstances Did Not Establish an Exception

The Court expressly acknowledged evidence suggesting that SLS acted in good faith and responded urgently to help the daughter of a longtime business associate. It also recognized the troubling allegation that Bangeman received insurance proceeds for SLS’s work but paid SLS nothing.

Nevertheless, those considerations did not authorize the Court to disregard ICRA. Nor did the opinion resolve Bangeman’s competing assertion that she used the proceeds to remedy defective work. The holding rests on the statutory disability, not on a determination that either party’s factual account was entirely correct.

5. A Legally Barred Claim Can Still Present a Nonfrivolous Appeal

The denial of attorney fees is an important qualification. The Court regarded SLS’s arguments about equitable exceptions as valid arguments to present, particularly given the record concerning insurance payment and nonpayment. Thus, affirmance on a clear statutory ground did not automatically make the appeal frivolous.

D. Potential Impact

• Registration becomes a decisive compensation issue. Contractors performing covered Idaho work cannot safely assume that good workmanship, urgent circumstances, or customer benefit will preserve a judicial remedy if they remain unregistered.
• Restitution pleading cannot routinely circumvent ICRA. Courts are likely to examine what compensation a claim seeks, rather than treating an equitable label as sufficient to avoid the statute.
• Registration dates and severability remain important. For contractors that register during a project, future disputes may focus on identifying and valuing distinct post-registration work. The opinion preserves, rather than abolishes, that limited route to equitable recovery.
• The protected party matters. Litigants relying on public-policy exceptions must explain why relief would serve the governing statute’s purposes. Professional-dispute precedents cannot simply be transferred to homeowner claims.
• Appellate fees require separate analysis. Prevailing on the merits does not establish that the opponent’s attempt to clarify precedent was frivolous.

The decision does not resolve every possible claim involving an unregistered contractor. It addresses compensation for covered construction services sought from a homeowner by a contractor that never registered. It should not be read as adjudicating unrelated tort claims, every interprofessional dispute, or statutory exceptions not presented in the appeal.
