## Facts

- Judith Young purchased real property in Thurston County, Washington, intending to support plans involving family and a potential relocation project.
- Judith added her nephew, James “Jim” Young, to title in the belief it would assist with permitting and approvals.
- Jim (a licensed contractor) and his wife, Shannon, agreed to perform extensive work to make the property suitable for the parties’ evolving plans and moved onto the property rent-free with Judith’s knowledge.
- Over several years, Jim and Shannon performed substantial improvements, including remodeling, demolition, repairs to buildings and well equipment, clearing, fencing, and other work.
- Evidence showed the improvements substantially increased the property’s market value; expert testimony valued the benefit in the hundreds of thousands of dollars.
- The parties’ relationship deteriorated, Judith did not proceed with the contemplated use, and she did not pay Jim and Shannon for the improvements.

## Issues

1. What is the proper measure of restitution for unjust enrichment when a nonowner improves another’s real property: the full benefit to the owner (e.g., increased market value or reasonable value of services) or a reduced amount based on the improver’s costs and circumstances?
2. Did the trial court err by deducting hypothetical “general contractor” costs (such as overhead and profit) from the market-value measure of the benefit conferred?
3. How does unjust enrichment (quasi-contract) differ from quantum meruit or contract implied in fact for purposes of measuring recovery?

## Decision

- The Washington Supreme Court affirmed the Court of Appeals.
- The court held that unjust enrichment restitution for land improvements is measured by the full market value of the benefit conferred (commonly the increase in property value or reasonable value of services).
- The trial court erred by reducing recovery through deductions tied to the improver’s cost structure or the fact the improvers did not incur certain contractor-type expenses.

## Legal Principles

- Unjust enrichment requires: (1) the defendant received a benefit, (2) at the plaintiff’s expense, and (3) retention of the benefit without payment would be unjust.
- Restitution for unjust enrichment is keyed to the defendant’s benefit, not an accounting of the plaintiff’s costs.
- For improvements to real property, restitution may be measured by the increase in market value attributable to the improvements or by the reasonable value of the services, but the measure should not be discounted based on the improver’s particular circumstances absent a specific equitable basis.
- Unjust enrichment (implied in law) differs from quantum meruit/contract implied in fact; the former prevents unjust retention of benefits where no contract governs, and it focuses on the benefit retained.

## Conclusion

The court held that when a nonowner improves another’s land and the owner retains the resulting benefit, unjust enrichment restitution is the full value of the benefit conferred (such as increased market value), and the award may not be reduced merely because the improver did not incur certain contractor-type costs.
