Utah permit fees typically run $218-$537 depending on jurisdiction and project value — most calculators use max(regional baseline $290, 1.2% of project value). UT permits $180-300.

How deep do footings need to be for a Composite deck in Utah?

Utah's frost depth is approximately 30″. Composite doesn't change the footing requirement — that's IRC R403.1.4-driven by frost line. Use Sonotube 10-12″ depending on tributary area. Verify with your local building department since AHJs sometimes require deeper depths than the state-published value.

Is Composite worth the money in Utah?

Composite vs PT pine over 25 years in Utah: PT pine = ~$38/sqft installed + ~$3/sqft/yr maintenance (stain/seal annually) = $118/sqft total. Composite mid-tier = $74/sqft installed + $0 maintenance = $74/sqft total. Composite typically wins the 25-yr TCO comparison by 20-40%, plus better resale value.
