What Drawings Are Needed For An Addition?

For an addition, the most useful starting package usually includes the existing building layout, the proposed design, site photos and any prior drawings that show the current structure.

Helpful Materials To Gather

• Existing floor plans and elevations
• Proposed addition drawings
• Photos of framing, foundations and affected areas
• Survey, architectural notes and any prior structural documents

The more clearly the existing and proposed conditions are documented, the faster an engineer can identify the right scope.
