The answer to 'what size electrical inspection do I need' is that the size of the electrical inspection required depends on the specific project or work being done in your home. Generally, electrical inspections are required for any new electrical work, major renovations, or when adding new electrical circuits or appliances.
The size and scope of the inspection will depend on the scale of the electrical work. Smaller projects like adding a new light fixture or outlet may only require a basic inspection, while larger projects like a full home rewiring will need a more comprehensive inspection. It's best to check with your local building or electrical permitting office to understand the specific requirements for your project.
