These are non-load bearing walls. Does the code still apply?
From the architectural courses I've taken, every wall bears a load of some sort.
What is considered to be a load bearing wall has a significant amount of weight being supported.
The nonload bearing wall is merely dividing an area (partition wall), yet it is supporting the weight of the joist run directly above it (as the years go by, the house/structure settles). For these walls, a single top is permitted, yet must be secured with 16d nails. Some areas of the country may require blocking in the corners.
When it comes to wall framing or framing the rough openings of doors and windows, the code (minimal standard) ensures rigidity and resistance to motion and warping/twisting as well as strength (structural support) and resistence to weather.
Also, what I wrote under the picture is inaccurate. I meant that the double header needs to be 2X6 minimum, not the double plate.
