APA's Ethical Principles in Planning guide ethical conduct for all who participate in the process of planning as advisors, advocates, and decision makers. Plans and programs must balance divergent interests. The planning process exists to serve the public interest. Those who practice planning need to adhere to a set of ethical requirements to ensure that the planning process best serves the entire community.

AICP members pledge to uphold the AICP Code of Ethics and Professional Conduct, which codifies the ethical conduct required of AICP members and establishes the principles to which professional planners are committed. An AICP member who violates the Code may face discipline including the revocation of AICP certification.

AICP members and others may contact the AICP Ethics Officer for informal advice related to ethics and the professional conduct of a certified planner.
