Summary

Encinitas encourages rainwater harvesting for landscape irrigation under California law that permits residential collection without a permit. Rain barrels and cisterns are allowed and promoted through the city's stormwater management and water conservation programs.

Rainwater Capture Act of 2012, which would provide that use of rainwater collected from rooftops does not require a water right permit from the state board. (2) Existing law, the Contractors’ State License Law, creates the Contractors’ State License Board within the Department of Consumer Affairs and provides for the licensing and regulation of contractors. Existing law authorizes a landscape contractor working within the classification of his or her license to enter into a prime contract for the construction of a swimming pool, spa, or hot tub, an outdoor cooking center, or an outdoor fireplace, if certain conditions are met. Under existing law, a violation of these provisions and related provisions of existing law is grounds for disciplinary action.

Full Breakdown

California Assembly Bill 1750 (2012) establishes the right of property owners to collect rainwater from rooftops for landscape irrigation without a permit. Encinitas supports rainwater harvesting as part of its stormwater management strategy and water conservation goals. Rain barrels up to approximately 250 gallons typically do not require permits. Larger cistern systems may need building permits depending on structural requirements and connection to plumbing systems. Collected rainwater may be used for landscape irrigation but is not approved for potable use without treatment. Rainwater collection systems must not create standing water that breeds mosquitoes: systems should be sealed or screened.

The San Diego County Vector Control Program monitors for mosquito-breeding standing water. Overflow from rain barrels must be directed away from building foundations and not onto neighboring properties. The Olivenhain and San Dieguito water districts may offer rebates for rain barrel purchases. Encinitas's proximity to coastal lagoons makes stormwater management a priority, and rainwater harvesting reduces runoff that carries pollutants into Batiquitos Lagoon, San Elijo Lagoon, and the ocean.

Violations & Fines

Rainwater harvesting is encouraged, not penalized. However, systems creating mosquito-breeding standing water may receive vector control citations. Unpermitted large cisterns with structural or plumbing connections may require retroactive permits.
