Typical all-in cost with a licensed electrician is $350 to $1,200 per single outdoor plug. A back-to-back tap of an adjacent indoor circuit lands at $180 to $350, a new 20A circuit with a 25 to 50 ft run hits $400 to $900, and a trenched run to a detached structure runs $1,200 to $3,000. DIY materials-only for a legal like-for-like swap is $25 to $55.
