Purpose: To augment permeability, aesthetic appeal, and environmental health by increasing landscape plantings and green spaces throughout the City.

Adopted on April 22, 2010, the Green Landscaping Ordinance applies to new construction and significant alterations, or more specifically the addition of a new dwelling unit; addition of new parking or garage; or front paving exceeding 25 square feet. The Ordinance aims to address screening, greening, street tree, and permeability requirements for street views and parking lots. Improved permeability on sidewalks, parking areas, and front yards will help to reduce flooding and sewer system overflow.

Property owners must utilize “climate appropriate” plants when constructing or reconditioning sidewalk areas. These plants will be utilized to construct “green” screening, applying to vehicle use or maneuvering areas. Additionally, San Francisco aims to maintain and eventually increase the number of street trees; with approximately 108,000 street trees throughout the City, property owners are responsible for 62% of those existing.

Specific guidelines affecting San Francisco property owners include:

• Front setback must include 20% plant materials, with permeable materials used for at least 50% of the setback area. More specifically, permeable yards can include in-ground plantings, porous asphalt or interlocking pavers that allow water to soak into the ground.

• Screening requirements apply to vehicle use areas (such as gas stations, car washes, and repair shops) greater than 25 linear feet.

• Dying and dead trees must be replaced within 6 months, or owners will face a fine for improper care.

Due to current economic conditions, the mandate is not imposed on existing property owners.
