Sonoma County Settles Drone Surveillance Lawsuit, Requires Warrants for Home Monitoring

Sonoma County has reached a settlement that effectively ends its warrantless drone surveillance, obligating the agency to secure a warrant before flying over private property except in limited emergency cases. The drone initiative, initially justified as a tool to locate unpermitted cannabis cultivation, gradually shifted to identify routine code violations such as illegal decks, fences, and outbuildings, generating at least $3 million in civil cannabis fines and numerous six-figure penalties that led to foreclosures.

In June 2025 the ACLU of Northern California and O'Melveny & Myers filed a lawsuit alleging constitutional violations, representing three affected homeowners. Under the settlement, the county will pay $50,000 to each plaintiff, inform residents of any drone monitoring, cease long-term image storage, and delete footage after 30 days unless tied to an active investigation, while providing flight logs to the ACLU biannually for two years.

The agreement also prompts a policy overhaul, and three officials who managed the program—Tennis Wick, Tyra Harrington, and Todd Hoffman—have departed, with county counsel Robert Pittman retiring. The county maintains that the settlement is not an admission of liability but preserves Permit Sonoma’s ability to use drones under new safeguards.
