Summary
Thousand Oaks allows residents to grow up to six cannabis plants at home without a permit, but only inside a locked room or fully enclosed accessory building: no outdoor grows, no visibility from the street or neighbors, and no detectable odor.
Personal cultivation of up to a maximum of six plants, not for commercial purposes, shall be allowed without a permit under the following conditions: (a) All cultivation of cannabis shall only occur within a secured room in a residence or secured fully enclosed accessory building located on a residential property... (b) No cultivation activity shall be visible from a public right-of-way, private street, or any neighboring property. (c) Cannabis cultivation shall not produce any odor detectable from any surrounding neighboring property, a public right-of-way, or private street.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-78: 2026 S-78 Supplement contains: Current city legislation passed through March 31, 2026).
Full Breakdown
The six-plant cap tracks the state-law minimum every California city must allow. Beyond the plant count, the ordinance layers on strict containment conditions: cultivation must happen in a space that can be fully locked, it can't be visible from a public right-of-way, private street, or neighboring property, and it can't produce any odor detectable off the property. Any structure used for the grow, a converted shed, garage, or spare room, still needs all its own building, electrical, plumbing, and mechanical permits and land-use approvals.
Violations & Fines
Growing without meeting these conditions falls outside the permit-free allowance and is treated as a violation of Chapter 29, which is a misdemeanor under §5-29.47 and a public nuisance under §5-29.45, exposing the grower to abatement costs and other remedies under §5-29.46.
