Unfinished spaces allow easier access, reducing labor costs.
Finished areas may require demolition and repair, increasing expenses.
Obstructions like HVAC systems can complicate wiring routes.

3. Service Panel Capacity

Upgrading a full panel or adding a sub-panel involves additional costs for equipment and permits.
