Texas Residents File Lawsuit Against MARA Holdings Over Noise at Granbury Bitcoin Mining Site
Residents of Hood County, Texas, have sued MARA Holdings, slamming the company over relentless noise from its Granbury bitcoin mining facility. The lawsuit, filed this week, accuses MARA Holdings of creating a public nuisance and disturbing daily life with round-the-clock industrial noise, according to Decrypt.
Plaintiffs allege the Granbury site’s operations have “destroyed the peaceful enjoyment” of their homes. They cite persistent mechanical hums, described in court documents as akin to “an idling jet engine,” that spike well above 85 decibels at the property line—a level OSHA classifies as potentially harmful with prolonged exposure. The noise reportedly runs nonstop, echoing across neighborhoods since MARA ramped up activity at the site in 2023.
The suit outlines months of complaints submitted to local authorities and direct appeals to MARA, which residents say went ignored or were met with vague promises to study the issue. MARA Holdings, one of the largest US-listed bitcoin miners, operates thousands of ASIC machines in Granbury, originally drawn to Texas for its cheap electricity and crypto-friendly regulatory climate. The plant’s expansion last year more than doubled its energy draw, increasing both its hash rate and its acoustic footprint.
The legal action seeks damages and a court order forcing MARA to reduce noise emissions or halt operations until compliance is met. The company has not issued a public response as of Thursday morning.
Impact of Noise Complaints on Cryptocurrency Mining Operations in Texas
Texas has become a magnet for bitcoin miners, lured by abundant power and political support. But the Granbury lawsuit highlights the mounting resistance from communities forced to live next to sites that never sleep.
Unlike traditional data centers, bitcoin mines use high-powered fans to cool racks of ASICs, generating a constant, low-frequency roar. In Rockdale, Texas, a similar dispute with Chinese-backed Bitdeer ended in a negotiated noise cap after residents documented decibel spikes and sleep disturbance. The Texas Blockchain Council estimates the state hosts 28% of US crypto mining capacity, but each new site now faces sharper scrutiny from counties wary of industrialization without local benefit.
For firms like MARA, noise isn’t the only problem. Texas grid operator ERCOT has repeatedly warned that mass mining can strain local infrastructure, especially during summer heat waves. In 2022, Riot Platforms received backlash for power draw during grid emergencies. Noise complaints add to a growing list of friction points—alongside water use, tax abatements, and skepticism about job creation.
The industry’s pivot toward AI infrastructure, including hosting for large language models, is only amplifying the stakes. MARA announced in May a strategic shift to dedicate part of its Granbury facility to AI compute clusters, which typically require even more sustained cooling and power than bitcoin mining alone. As AI demand surges, so does the risk of longer operational hours and higher dB emissions. Local governments are being forced to reconsider zoning laws, noise ordinances, and tax incentives originally written before the AI boom.
State lawmakers in Austin have so far resisted sweeping restrictions on mining, preferring to let localities negotiate with operators. But lawsuits like Granbury’s create legal risk that could slow new deployments—or push miners to retrofit existing sites with expensive soundproofing. The industry’s bet on Texas now comes with more regulatory uncertainty than miners faced in the 2021 post-China-ban gold rush.
What the MARA Lawsuit Means for the Future of Crypto Mining and AI Infrastructure in Texas
A court order against MARA could set a precedent with national reach, signaling that local noise ordinances are enforceable against crypto and AI infrastructure—regardless of state-level permissiveness. If the plaintiffs prevail, MARA may be forced to retrofit the Granbury site with acoustic barriers, limit operating hours, or relocate machines, all of which could raise costs and reduce mining profitability.
Other Texas counties are watching closely. Legal victories for residents would embolden communities in Navarro, Milam, and Dickens counties, where new bitcoin and AI data centers are planned. Smaller operators with thinner margins are especially vulnerable if required to invest in noise abatement or navigate protracted litigation.
For the industry, the case is a stress test of its strategy to pivot from pure bitcoin mining to AI hosting. Hyperscale AI clusters are even less compatible with suburban and rural neighborhoods than crypto rigs. Companies that fail to address local quality-of-life concerns risk losing their “social license” to operate—particularly as AI becomes a political flashpoint.
Key developments to watch: whether MARA settles and agrees to engineering fixes; if state lawmakers intervene to clarify local authority over mining noise; and how other operators preemptively respond to mounting complaints. The outcome in Granbury will shape how quickly—and where—Texas’ next wave of AI and bitcoin infrastructure comes online. Miners who ignore community pushback could soon find themselves in court, not just on the blockchain.
