This is a dicey area to be sure. What one may or may not do relative to architectural practice is a product of the licensing laws in your individual state. Insofar as I am aware, no two are alike. For example, in Michigan (my state) you may design one and two family residential structures of up to 3,500 square feet in occupiable area (approximately 6,000 square feet gross area) without a license. Virtually everything else, including anything non-residential, requires a license. I believe that we have one of the more restrictive licensing laws in the country.
The law in each state defines certain activities that constitute the practice of architecture. Simply put, in order to render the prescribed services or engage in the prescribed conduct, one must be an Architect (I tend to discount the use of the term "licensed Architect" because it seems redundant and confusing - one has a license in which case one is an Architect - without a license one is not an Architect, hence there is no such thing as an "unlicensed Architect" as the term "licensed Architect" would imply). If you work for an Architect on the things you describe under the Architect's direct supervision and control you are probably ok. However, if you plan to actually start an independent business then another series of issues come into play including the degree to which you may use the term "architectural" in conjunction with your business.
I understand the desire to move in that direction and I have encouraged a number of young professionals here in Michigan to do exactly what you are contemplating. The advantage I have is that I know Michigan law and can render them intelligent advice based on that knowledge. Since knowledge of state law is the only way to properly answer your question, my best suggestion would be for you to contact your state chapter and ask them to direct you to someone who can provide that advice in your state.
As you imply, the penalty for going astray could be limitations on your ability to take your licensing exams. Your idea is becoming more and more common, and frankly could a means by which you gain experience while providing a valuable service to established Architects and firms. Get the advice you need to do it right.
Good luck. Feel free to contact me directly if you would like to discuss further.
