Using Fence Posts for Load-Bearing in Pergola?

[Paw85]

I'm looking to construct a lean-to-wall pergola and plan to use 100 x 100 mm wooden posts. However, I can only find fence posts. Can these fence posts be used as load-bearing elements? They will be placed on height-adjustable shoes and will have no direct contact with soil or water. Thanks.

You say load bearing but really it's not it's only a pergola, they'll be fine.

Yes. You can put the shoes on concrete pads cast into the ground, raised a few inches and slightly domed to throw off water.
