Gardena has no ordinance prohibiting rainwater harvesting, and rain barrels for outdoor irrigation are generally allowed. Simple laundry-to-landscape greywater systems usually need no permit under the California Plumbing Code, while plumbed greywater systems and large rainwater cisterns require a plumbing permit from the City's Building Division.
Gardena does not restrict capturing rainwater. Collecting roof runoff in rain barrels or small cisterns for outdoor irrigation is allowed and supports the water conservation goals of both the City and Golden State Water. There is no local ban on rain barrels, and California law encourages residential rainwater capture. Greywater reuse is governed by state law rather than a special Gardena ordinance: under the California Plumbing Code (Title 24, Part 5, Chapter 16 and 16A), a simple 'laundry-to-landscape' clothes-washer greywater system that meets the state conditions generally does not require a permit, while more complex greywater systems (for example, systems tied to showers or multiple fixtures) and plumbed rainwater cisterns require a plumbing permit from the Gardena Building Division.

There is no penalty for using a rain barrel for outdoor irrigation. Installing a plumbed greywater system or a large rainwater cistern without the required plumbing permit, creating a cross-connection with potable water, or allowing uncontrolled discharge can trigger building/plumbing
