Which of the following could be a valid ground for suspension of an architectural license?

A valid ground for suspension of an architectural license is typically based on behaviors that undermine the integrity of the profession or the public's trust. A conviction of a relevant crime, especially one related to the practice of architecture, indicates a breach of legal and ethical standards and can directly impact the ability to perform duties safely and competently.

Convictions that demonstrate moral turpitude, fraud, or professional misconduct can warrant disciplinary action, including license suspension, as they compromise the trust placed in licensed professionals by clients and the public. This aligns with licensing boards' responsibility to protect the health, safety, and welfare of the community.

In contrast, while failure to pay taxes and violations of business ethics may be serious issues, they do not always lead directly to license suspension unless they pertain to a violation of specific laws regulating the profession. A change of residence is typically not a factor that would influence licensing status unless it affects compliance with state laws where the practice is licensed.
