Sonoma County Faces Lawsuit Over Drone Surveillance: ACLU Calls It a “Runaway Spying Operation”

Estimated read time 4 min read


Today, three Sonoma County residents, backed by the American Civil Liberties Union (ACLU), filed a lawsuit against the county, alleging that its use of drones for code enforcement violates privacy rights. The suit claims that what began as a program to monitor illegal cannabis cultivation in 2019 has spiraled into widespread surveillance, with over 700 drone flights targeting private properties for various code violations without warrants, according to the Los Angeles Times.

Drone Technology Under Scrutiny

The drones in question are equipped with high-powered cameras and zoom lenses, capable of capturing detailed aerial images of private backyards. Initially deployed to identify illegal cannabis grows, the county’s drone operations have since expanded to include non-cannabis-related violations such as unpermitted construction, junkyard conditions, and zoning issues.

In 2024 alone, nearly half of the county’s drone flights were for these non-cannabis violations, the complaint states. The ACLU argues this practice violates the California Constitution, which protects against unreasonable searches and seizures.

“The use of drones over someone’s private space raises a question of what is considered private,” said Ari Ezra Waldman, a law professor at UC Irvine, in the complaint.

Regulatory Gaps and Privacy Concerns

California currently lacks specific laws regulating drone use by code enforcement agencies. A 2015 bill that would have restricted drones from flying over private property without permission was vetoed by then-Governor Jerry Brown, who argued it might lead to “burdensome litigation” for hobbyists and commercial users.

Ego Pilot Moose

The absence of clear regulations has allowed Sonoma County to loosen its drone policies over time. In 2019, inspectors were required to have a complaint before deploying a drone, but now officials can launch “discretionary proactive investigations” without such prerequisites, the lawsuit alleges.

“For too long, Sonoma County code enforcement has used high-powered drones to warrantlessly sift through people’s private affairs,” said Matt Cagle, a senior staff attorney at the ACLU Foundation of Northern California.

Impact on Residents and Industry Implications

The lawsuit highlights the personal toll on residents. Plaintiff Nichola Schmitz, who is deaf, alleges she was unaware of a drone hovering above her property on October 10, 2023, until a worker pointed it out. The drone’s flight resulted in a red tag on her gate, citing two violations: illegal grading and an unpermitted cabin built in 1981.

Schmitz faces $10,000 in fines and spent $25,000 on a contractor to address the grading issue. “This horrible experience has shattered my sense of privacy and security,” Schmitz stated in the complaint. Another plaintiff, Benjamin Verdusco, sold his home after learning of drone surveillance in 2021.

For the Drone Industry, this case underscores the tension between technological advancement and privacy rights. Drones are increasingly used by government agencies for tasks like disaster response and environmental monitoring, but their application in code enforcement raises ethical questions.

The outcome of this lawsuit could set a precedent for how drones are regulated in residential areas, potentially impacting operators and manufacturers. Drone professionals and recreational pilots may face stricter guidelines if courts rule in favor of the plaintiffs, while agencies might need to invest in warrant processes or alternative technologies to comply with privacy laws.

Looking Ahead

Sonoma County has stated it is reviewing the complaint and takes “the allegations very seriously.” As drone usage continues to grow—spanning emergency response, infrastructure inspection, and now code enforcement—the balance between innovation and individual rights remains a critical issue. The ACLU’s push for accountability could prompt California to revisit drone regulations, ensuring that the skies don’t become a free-for-all for surveillance. For now, the drone industry watches closely as this Legal battle unfolds.
