What is a practical priority checklist for building a deck?

For a new deck in Snohomish County, here how we look at and rank priorities from a practical standpoint:

1. Structural safety, drainage, and moisture control
2. Durable framing, connections, and installation quality
3. Surface safety, comfort, and weather suitability
4. Lifetime cost and maintenance effort
5. Appearance, colors, railings, and trim
6. Extras such as lighting, privacy screens, and built-in seating

Appearance matters, but it is much easier to replace surface boards than to correct a poorly designed structure.
