Tips

Laramie County does not list a separate flat-rate 'deck permit' — decks, patios, and porches are charged under the general project valuation chart at a rate that varies by whether the structure is enclosed, covered, or open-air.
A deck built to support a roof load requires engineering — plan for a stamped structural submittal in that case.
Basement finishes require showing the ENTIRE basement plan, not just the area being finished.
