Do you need a building permit in Utah?

Usually yes, but not from Utah itself: permits are issued by the city or county, not the state, so the rule that governs your project is the one your own jurisdiction publishes. 8 of those local rules require a permit outright, 4 depend on a size or scope condition the office publishes, and 0 need none. Utah sets the building code those local rules derive from; your city or county sets the threshold and the fee.

Building without a permit in Utah

Utah law itself makes unpermitted building an offense. Inside a city or town, it is an infraction to erect, construct, reconstruct, alter, or change the use of any building without approval of a building permit (10-20-1001(2)(b)); an infraction is punishable by a fine of up to $750 and no jail (76-3-301(1)(e), 76-3-205).

Penalties, the as-built path, and what the statute actually says

What each Utah jurisdiction publishes

One line per jurisdiction, written from its own rules rather than from a state summary. This is the section that used to be a list of links, and the states with the fewest jurisdictions to compare are the ones it says the most about.

Salt Lake City 13 rules
8 of 12 projects always need a permit and 4 turn on the size or scope of the work. The ones that depend on the project are bathroom remodel, deck, pool and shed. Published thresholds include deck at 30 inches and pool at 24 inches. 1 question is unresolved because the jurisdiction publishes no answer.
