Frost reaches about 36 inches in Utah. Any bid for footings, foundations, or buried lines should dig at least that deep. If the depth is not written in the quote, ask.

How far in advance do I need to call before digging in Utah?
At least 2 working days. Utah 811 takes locate requests statewide and has underground utilities marked before any excavation. Hitting an unmarked gas or power line can injure the crew and lead to costly repairs.
How deep do footings need to be in Utah?
In Utah, footings typically need to extend below the frost line, which is around 36 inches here. A local contractor will confirm the code requirement for your site.
When is the best time of year to dig in Utah?
Spring through fall is the main excavation season in Utah. A frost line around 36 inches makes winter digging slower, and the spring thaw leaves sites soft.
