Granbury residents sue MARA over Bitcoin mine noise

Nine residents of Granbury, Texas, filed a lawsuit against MARA Holdings on Friday in the U.S. District Court for the Northern District of Texas, alleging continuous noise, vibrations and low‑frequency sound from the company’s Bitcoin mining facility have damaged their health, made homes difficult to live in and reduced property values. The complaint requests more than $1 million in damages and demands a jury trial.

The plaintiffs include members of several families who say they live as close as 0.01 miles (about 53 feet) from the site. The filing describes cooling systems that run continuously and produce noise and vibrations that penetrate houses. The suit lists four claims: private nuisance, negligence, intentional infliction of emotional distress and restitution.

The complaint links the facility’s emissions to a range of physical and psychological effects, including insomnia, headaches, tinnitus, anxiety, fatigue, hearing loss and hypertension. The filing also reports changes in livestock behavior and reduced wildlife activity. One passage states the noise and vibrations from “low‑frequency sound emissions” have interfered with plaintiffs’ use and enjoyment of their properties and resulted in personal injuries.

Plaintiffs allege conditions worsened after MARA took over operations at the Granbury site in 2024 and that the company knew of the impacts but did not properly manage or mitigate the facility’s effects.

In a company statement included in the record, MARA wrote it is “committed to being thoughtful and considerate members of our new community” and has been seeking community input. The company wrote it has shut down some air‑cooled units, built sound barriers and is moving to liquid immersion cooling to reduce sound. The plaintiffs say those measures have not resolved the problem.

Attorneys for the plaintiffs and for MARA did not immediately respond to requests for comment. The suit asks the court to hold MARA responsible for the alleged harms and to order restitution for losses tied to diminished use, enjoyment and value of the residents’ properties.

The filing arrives amid industry changes as Bitcoin mining operators repurpose power and cooling infrastructure to host artificial intelligence and high‑performance computing workloads. Large data centers and computing sites across the United States have prompted complaints from neighbors over noise, electricity demand, water use and strain on local services. In Maine, state lawmakers recently approved a temporary ban on new large‑scale AI data centers, citing concerns about community impacts.

The case remains pending in the Northern District of Texas, where the complaint seeks damages exceeding $1 million and a jury trial.
