We hired an architect named Michael Gottwald (DC) to draft the plans. But if you take them down to DCRA yourself and use the homeowner center, they don’t even need to be stamped by an architect. As long as there’s nothing load bearing requiring a structural engineer, you can take in 4 copies (ours were on legal size paper) walk straight in to the homeowners department and they will help you. Try to create the forms on line but tell them you don’t know what you’re doing and they’ll walk through them with you. This saved us several thousand dollars.
