What’s different about Aurora
Aurora sits in the Chicago metro, sharing its higher labor costs and permitting while suburban scale keeps pricing below the city core.
- Footings have to reach below the frost line, so deeper excavation adds cost.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
How the cost is built
Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.
