How far in advance do I need to call before digging in Oregon?
At least 2 working days. Oregon 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.
Do excavation contractors need to be licensed in Oregon?
Yes. Oregon requires a state contractor license (OR CCB license) for this work, regulated by Oregon Construction Contractor Board. Look up the license number before you sign a contract.
How deep do footings need to be in Oregon?
In Oregon, footings typically need to extend below the frost line, which is around 24 inches here. A local contractor will confirm the code requirement for your site.
When is the best time of year to dig in Oregon?
Most of the year works in Oregon. Occasional winter freezes can firm up the top few inches of soil, but the 24-inch frost line clears quickly.
