Working with Professionals

Landscape professionals provide many different services. There are landscape architects, landscape designers, landscape contractors, horticulturalists, and arborists. While there is some overlap among these professions, there are also important distinctions:

Landscape architects have advanced education, professional training, specialized skills, and licensure in 46 states, including California. Licensure is obtained through education, experience, and successfully passing a licensing exam. A landscape architect manages any job concerning the design and use of outdoor space and the land. The scope of the profession includes site planning, town and urban planning, park and recreation planning, garden design, and historic preservation. They provide analysis, planning, design, management, and stewardship of outdoor space and land. For more information, contact the American Society of Landscape Architects at www.asla.org.

Consult with your local nursery staff.

Landscape designers - focus primarily on landscape garden design, environmental management, and the preservation of historical landscapes. For information, contact the Association of Professional Landscape Designers.

Hiring a Landscape Architect:

Request the architect’s state license number and call the State License Board at (800) 321-2752; or look online to verify that the license is current and in good standing. Request a complete description of the work to be done; quantities and sizes of all materials to be used including plant materials; brand name and type of irrigation equipment; and a landscape water management plan.
Prepare a realistic budget. One rule of thumb is to invest no more than ten percent of your property’s worth into landscaping. This figure should include all design and installation costs, as well as plant materials.

Hiring a Landscape Contractor

California state law requires anyone who contracts to do landscape work to be licensed by the Contractors State License Board if the total price of the job (including labor and materials) is $500 or more. Licensed contractors are bonded and must complete four years experience at journeyman or higher in the same trade to apply for a license.

Typically, unlicensed persons are not bonded and may not have liability or worker’s compensation insurance. Be aware that if you hire an unlicensed person, you may be financially responsible if injuries, fire, or property damage occurs.
