Matthew Prince, the billionaire CEO of Cloudflare, has cleared a significant legal hurdle in his quest to build an 11,000-square-foot mansion in Park City, Utah. A Summit County judge dismissed two lawsuits filed by local residents opposing the construction, allowing Prince and his wife, Tatiana, to proceed with their ambitious project after nearly two years of litigation.
The legal disputes began in 2022 when Prince proposed the construction of a sprawling estate in Park City’s historic Old Town, designed to reflect the area’s mining heritage. Despite initial approval from the Park City Planning Commission in early 2024, a group of ten neighbors, including Eric Hermann and his wife, Susan Fredston-Hermann, appealed the decision, citing concerns over the mansion’s size and its compatibility with the historic character of the neighborhood.
Community Concerns and Legal Battles
Hermann expressed his objections, labeling the proposed mansion as “out of proportion” with the surrounding area. He noted that renderings of the project often omitted nearby structures, making it difficult to assess its scale relative to existing homes. The dispute escalated when Prince filed a lawsuit against the Hermanns, alleging that their Bernese mountain dogs had harassed his family while they were on a nearby trail. This claim sparked public interest, leading to a satirical response from the community, including “Save Sasha and Mocha” stickers appearing around town.
As the legal battles continued, Prince’s family dynamics became a focal point, with Prince acknowledging the challenges of being a wealthy individual in a small community. “I get that we’re rich a**holes, but at some level I’m also a father, and I have to protect my daughter,” he stated in an interview.
Recent Developments and Future Plans
In late 2025, a new municipal code allowed for the resolution of land-use disputes through consent agreements. On January 15, 2026, the Park City Council approved a consent agreement for the Princes’ project, which Judge Richard Mrazik ruled rendered the Hermanns’ lawsuits null and void. Prince’s attorney, Bruce Baird, expressed satisfaction with the ruling, indicating that construction could now proceed.
However, the Hermanns remain steadfast in their opposition, claiming that the consent agreement violated their rights and the city’s regulations. They have filed additional lawsuits challenging the city’s decision to extend building permits for the Princes’ project, arguing that the revised plans do not comply with updated building height and mass regulations.
As the legal landscape continues to evolve, both parties are preparing for upcoming court dates in December, where they will address the ongoing disputes regarding the mansion’s construction and the alleged dog harassment. The Hermanns maintain that their dogs are gentle and loving, while they hope for a fair discussion regarding the merits of the mansion’s design and its impact on the historic district.
