Hiring a Landscape Architect:

  • Request the architect's portfolio. Speak with past clients, if possible. If water-efficient landscape is of interest, ask about water conservation gardens they may have designed.

  • 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.

  • Request the architect’s state license number and call Oregon Landscape Architect Board at 503-589-0093 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 plants materials; brand name of irrigation equipment; and a landscape water management plan.

  • Request a copy of the contract and expected method of payment.

Hiring a Landscape Contractor

Oregon state law requires anyone who contracts to do landscape work to be licensed by the Oregon State Contractors Board if the total price of the job (including labor and materials) is $500 or more.

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.
