The American Institute of Architects’ (AIA) 2007 Code of Ethics & Professional Conduct calls Architects to include Pro Bono Services in professional practice.
Ethical Standard 2.2 Public Interest Services: Members should render public interest professional services, including pro bono services, and encourage their employees to render such services. Pro bono services are those rendered without expecting compensation, including those rendered for indigent persons, after disasters, or in other emergencies.
