Do I need engineered deck drawings?

A deck package should let a reviewer follow loads from decking and framing through joists, beams, posts, connections, and footings or other supports. I look for a clear attachment or freestanding-support story in the intake materials; where a deck attaches to a house, a ledger line on a plan is not proof that the building can accept the connection.

• Plan, elevations, sections, member sizes, spans, and spacing
• Beam-to-post and post-to-footing load transfer
• Ledger, rim, flashing, fastener, and house-framing assumptions
• Lateral connection or bracing details where part of the design

Height, stairs, guard geometry, drainage, soil, frost or exposure criteria, occupancy, and proximity to property or other structures affect the design and coordination. A freestanding deck may need a different foundation and lateral strategy than one relying on an existing wall.

• Footing size and depth based on verified soil and project criteria
• Stair stringers, landings, guards, handrails, and attachment points
• Surface drainage, post durability, and separation from the building
• Snow, wind, seismic, or other project-specific load inputs

The final deliverable may include calculations, notes, details, schedules, and a seal when the responsible engineer accepts the eligible work. Product instructions, site work, construction means, and authority review remain separate responsibilities and should be coordinated rather than implied by a generic deck template.

• Current architectural or site background and deck dimensions
• Photos of the attachment wall, rim, foundation, and existing framing
• Manufacturer data for proprietary connectors or support systems
• Clear assumptions, exclusions, and field-verification notes
