In some states, a certificate of authorization (COA) is required for what purpose?

• A. To authorize a corporation to practice architecture
• B. To register a business
• C. To grant a building permit
• D. To certify a license

Answer: (A)

A certificate of authorization is what allows a corporation or professional firm to practice architecture. It’s issued by the state regulatory board and ensures the firm can legally offer architectural services to the public, with licensed architects responsible for the work. The individual architects still need licenses, but the COA covers the business entity itself so it can operate as a firm.

This is different from getting a building permit (handled by local authorities) or simply registering a business (a separate process with state-level or local agencies). It’s also not a certification of an individual license—the COA is about the firm’s authorization to provide architectural services.

So, in states that require it, a corporation must obtain a COA to practice architecture.
