Stamped Plans for Sunroom

I need a set of engineer-stamped construction drawings for a wood-framed three-season room that will sit on my existing deck. At the moment I only have the concept—no sketches or architectural plans—so the scope begins with translating my ideas into permit-ready drawings and ends with sealed documents I can submit to the local building department.

Key parameters
• Structure: wood posts, beams, studs and sheathing designed to tie into the current deck framing and footings.
• Roof: conventionally framed with asphalt shingles to match the house.
• Compliance: plans must meet current local codes and include all calculations, elevations, sections, connection details and load paths your stamp requires.

I will supply deck photos, measurements and site information right away. Please outline how you handle field verification (if needed), the stamp jurisdiction you can provide, and the timeline to reach a permit-ready set.
