Utah Court of Appeals

Can sophisticated real estate parties claim mutual mistake for zoning violations? High Desert Estates LLC v. Arnett Explained

2015 UT App 196
No. 20140146-CA
August 6, 2015
Affirmed

Summary

High Desert Estates LLC and Brett Folkman purchased property to facilitate development but later discovered zoning violations prevented building houses without plat amendments. They sued for rescission claiming mutual mistake about the property’s buildability, but the trial court found they failed to prove the mistake was material to their agreement.

Analysis

In High Desert Estates LLC v. Arnett, the Utah Court of Appeals addressed whether sophisticated real estate parties could rescind a purchase contract based on alleged mutual mistake regarding zoning compliance and buildability.

Background and Facts

High Desert Estates sought to develop adjacent property and needed road access to a public highway. When landowners refused easements, High Desert arranged for Brett Folkman to purchase the Arnetts’ property in 2007. Two years later, Folkman discovered the property had been improperly subdivided without required plat amendments, preventing house construction without rezoning. The developers sued for rescission, claiming mutual mistake about the property’s buildability “as is.” The purchase contract contained no warranties regarding suitability for construction.

Key Legal Issues

The court addressed two primary issues: whether the trial court’s order was final and appealable despite pending objections, and whether the developers proved mutual mistake by clear and convincing evidence. The mutual mistake analysis required proving that any mistake was material to the parties’ agreement and concerned a basic assumption of the contract.

Court’s Analysis and Holding

The Court of Appeals found the trial court’s order final, applying the rule that signing a proposed order implicitly overrules pending objections. On the merits, the court applied clear error review to the trial court’s factual findings. The trial court determined that sophisticated real estate parties have constructive knowledge of recorded plat maps and zoning ordinances. More critically, the evidence showed the property’s primary purpose was road access, with house construction being merely “a bonus,” making any mistake about buildability immaterial to the agreement.

Practice Implications

This decision emphasizes that sophisticated parties cannot easily escape real estate contracts through mutual mistake claims. Courts will impute constructive knowledge of public records and zoning laws. The materiality requirement for mutual mistake is strictly enforced—parties must prove the alleged mistake concerned a fundamental assumption underlying the bargain, not merely an ancillary benefit.
