Common Questions

Yes, in Denver, a permit is required for any deck that is attached to the house or more than 30 inches above the ground. Ground-level freestanding decks under 200 square feet may be exempt.

Permit fees in Denver are valuation-based, typically ranging from $200 to $900. For example, a $12,000 project may incur a $115 base fee plus plan review charges, while a $25,000 project costs roughly $219 plus extras.

Labor costs for deck installation in Denver currently average between $17 and $40 per square foot, depending on the complexity of the design and the material being used.

Due to extreme temperature swings and heavy snow loads, composite decking (costing $85-$100+ per sq ft installed) or hardwoods like Ipe are recommended over softwoods to prevent warping and cracking.
