Excavation: frequently asked questions
These answers are general. For your situation, check the official sources listed below or ask a professional.
Do I need to call 811?
Yes, before any digging: it is free and required in every state.
Do I need a permit?
Often for grading, foundations and utility connections; your builder or excavator can tell you.
What if they hit rock?
Rock can require a breaker or blasting and changes the price; ask how the quote handles it.
