Tips
- There is no separate flat 'deck permit' fee in Natrona County — it is charged under the same general valuation-based building-permit table as any other addition, based on the deck's declared construction cost.
- Confirm your zoning district's accessory-structure setback distances before finalizing deck placement, since these vary (e.g., 5 ft side/front and 8 ft rear in SR and RR districts) — check with Natrona County Planning if unsure.
