Do I need a permit for retaining wall construction in Unincorporated Grand County?
It depends. Whether retaining wall construction needs a permit in Unincorporated Grand County comes down to the details of your project.
Colorado has no statewide building code, so the height at which a retaining wall needs a permit is set by your city or county. Many start from the model code figure of 4 feet, or any height that supports a surcharge, but that is a local adoption, not a Colorado rule. Tall walls, walls near property lines, and walls holding back a driveway or slope often need engineered design, and grading that changes drainage can need separate local review.
