Do I need a permit to build a deck in Aurora?
Yes — most deck projects in Aurora require a building permit if the deck is attached to the house, over 30 inches off the ground, or over 200 sqft. Permits cost $175–$450 in Aurora and require structural drawings and a post-installation inspection. A licensed CO contractor will handle permits as part of the project. Unpermitted decks must be disclosed at sale and may need to be removed or permitted retroactively.

What is the ROI on a deck in Aurora?
