What is a California Corner?

Since three pictures are worth 3,000 words, let’s take a look at three diagrams. Before we start, bear in mind the whole “corner” scenario revolves around providing a proper nailing surface or backing for drywall in the corner. You can see in illustration A that there’s nothing to secure the drywall to on one of the walls. This type of corner is called a “Tick off the drywaller corner.” In the “Traditional corner” (B) you can see there’s adequate backing for drywall on both walls. The downside is that it requires 4 studs (or 3 studs with scrap blocking) to create the corner and there’s no space for insulating the corner. The “California corner” (C) can be built using fewer studs, plus it provides room for tucking in a few inches of insulation. The origin on the name remains one of those great carpentry mysteries.
