The process is designed to inspire project teams to seek innovative solutions that support public health and our environment, while saving building owners money over a project’s life cycle. Here's how to get started:


Select a rating system for your project, and learn basic program requirements

Each LEED rating system groups requirements that address the unique needs of different building and project types.

  • For LEED v4: Discover LEED to determine which rating system is the best fit and then follow up by reading the Selection Guidance to make sure you've made the right choice.
  • For LEED 2009: Use our other Selection Guidance to choose between the available LEED 2009 rating systems.

Make sure to check out the Minimum Program Requirements to know if your project is eligible for LEED certification.

Review our series of LEED certification guides

We strive to make the LEED customer experience the best it can be. Our Certification Guides lead projects through the LEED process under each rating system, starting from registration to certification.

Decide which credits your project should pursue

Prerequisites are the green building standards every project must meet. Credits allow project teams to customize how they pursue certification. By fulfilling credits, projects earn points that determine its certification level: Certified (40-49 points), Silver (50-59 points), Gold (60-79 points) and Platinum (80+).

Equip your project with the right tools

We have developed a set of LEED Reference Guides for each rating system to help project teams understand each credit and prerequisite. We also have built a comprehensive online toolkit, which includes key supplemental material for LEED projects like addenda and sample forms.

LEED fees & deadlines


There's a flat registration fee and a certification fee, which is based on a project's size and the rating system the project was registered under. Registration fees are due at a project's registration; certification fees are due when an application is submitted for review. View detailed fee tables.


At any given point, LEED rating systems are either open for registration and certification; closed for registration, but open for certification; or closed for registration and certification (sunset). View the deadlines table.
