Wiring attached shed from existing outlet

Iím building a lean-to shed attached to the house, and want to wire a light switch and receptacle (GFCI of course) into the shed from an exterior outlet on the same wall. I realize the wiring has to be run thru waterproof conduit, such as PVC or EMT. Is a box (LB or other) required on the shed to run the wiring inside?

Welcome to the forums.

Typically you'd use UF which is outdoor rated NM cable.
You could use PVC conduit but that may be hard to attach to your existing receptacle.

It maybe possible to add a weatherproof box extension with conduit holes to the existing outside outlet to where you can run PVC conduit to a LB on the shed for the wire to enter the shed. Use UF cable amp size to match the exiting circuit amps and use 3/4" PVC conduit for the outside run. It will be a pain getting the UF through the conduit but it can be done. Once in the shed use a junction box and switch to regular NM-b.
