Water Efficient Irrigation Ordinance

Landscapes that utilize water-wise principles not only conserve water but help prevent runoff, provide a natural habitat for local wildlife, result in reduced maintenance costs, and contribute to the beauty of our urban landscapes.

To ensure the efficient use of water for all San Francisco landscapes, projects with 500 square feet or more of new or modified landscape area are required to comply with the Water Efficient Irrigation Ordinance. Projects must design, install, and maintain efficient irrigation systems, utilize low water-use plantings, and set a Maximum Applied Water Allowance, also known as an annual water budget.

Learn how to comply with the ordinance.

Is this ordinance the same as the Green Landscaping Ordinance?

No, the Water Efficient Irrigation Ordinance is not the same as the Green Landscaping Ordinance. The Green Landscaping Ordinance is part of the San Francisco Planning Code and sets requirements for greening front setbacks of properties, screening and greening parking areas, and selecting and maintaining street trees.
