Deck builders in Post Falls
Decks for one of Idaho's fastest-growing cities, between the Spokane River and the Washington line.
Post Falls had 38,485 residents at the 2020 census, up about 40 percent from 2010. Frederick Post built a lumber mill at the falls on the Spokane River in 1871, and the river still forms the city's southern edge. Most of the newer neighborhoods spread north across the flat Rathdrum Prairie toward I-90 and beyond.

When does Post Falls require a deck permit?
The city's residential deck guide says a permit is needed if the deck is over 200 square feet, attached to any structure, has any walking surface more than 30 inches above grade (measured including a 36-inch strip around the deck), or serves the main exit of the building. The Post Falls Building Division handles review.
City-specific details
Post Falls lists a 24-inch minimum frost depth, with an exception allowing 12-inch footings for freestanding decks built with an approved footing type. It requires lateral support on every deck, treated ledgers at least 2x8, and a beam calculation report for glulam or LVL. Engineering is typically required once the walking surface is more than 12 feet above grade. A builder who works here regularly will already be drawing plans to these rules.
