San Mateo encourages drought-tolerant and native landscaping consistent with California's MWELO. New landscapes over 500 square feet must comply with water-efficiency calculations. California law prohibits cities from banning drought-tolerant plants.
San Mateo follows California's Model Water Efficient Landscape Ordinance (MWELO) for new and renovated landscapes exceeding 500 square feet. MWELO requires Maximum Applied Water Allowance calculations and appropriate plant selection. Cal Water Service provides resources and potential rebates for water-efficient landscaping. California Government Code Section 65595 prohibits cities from banning drought-tolerant landscaping. San Mateo's Mediterranean climate (USDA Zone 10a-10b) supports a wide range of native California plants including coast live oak, toyon, California fuchsia, and native grasses. The city's protected tree ordinance (Chapter 13.40) supports retaining existing trees as part of the landscape. New development must include landscaping plans emphasizing water efficiency.
Non-compliance with MWELO on applicable projects may delay permits. No penalties for existing native landscaping. Failure to maintain required landscaping on commercial properties may be cited.
