Judge Tosses Lawsuits in Utah Mega-Mansion Dispute Involving Tech Billionaire

A Utah judge has dismissed two lawsuits that challenged the construction plans of Cloudflare CEO Matthew Prince for an 11,000-square-foot mansion in Park City. The ruling, issued by Third District Court Judge Richard Mrazik, stated that a consent agreement approved by the Park City Council in January superseded the land-use decisions that were at the center of the dismissed cases.

Prince and his wife, Tatiana, purchased the property in 2020 with the intention of replacing two existing homes with a large new residence overlooking the historic Old Town. The project has faced years of opposition from neighbors Eric Hermann and Susan Fredston-Hermann, whose property adjoins the Prince lot.

The legal disputes have included challenges to the home's height, floor area, roof design, and compliance with Park City's historic regulations. One significant point of contention involved historic-design approval, including requirements for modifications to the roof and windows facing east. Prince has maintained that his project adheres to regulations and has undergone extensive review.

The feud escalated in 2024 when Prince's company filed a lawsuit against the Hermanns, alleging that their Bernese mountain dogs, Sasha and Mocha, were frequently unleashed, trespassed on his property, defecated there, and aggressively approached his family. Prince claimed the dogs had harassed his elderly mother and barked at his infant daughter. The Hermanns denied these allegations, asserting that their dogs were well-behaved and non-aggressive, which led to local support for the dogs, including "Save Sasha and Mocha" stickers appearing around the town.

The consent agreement, approved by the City Council with a 3-1 vote, was facilitated by a Utah law enacted in November 2025, which permits municipalities to settle land-use litigation through such agreements. However, the Hermanns argue that this agreement cannot resolve their independent legal claims without their consent and that the city cannot alter land-use and historic regulations through this method without a formal legislative process.

Despite the dismissal of two lawsuits, the broader legal conflict is ongoing. The Hermanns have filed a separate lawsuit challenging the consent agreement itself, and attorneys for all parties are scheduled to return to court on December 29. Excavation work at the Prince property was reportedly underway in mid-September. Prince is also a co-owner of The Park Record, a local newspaper.
