Small jobs
Utah's small job exemption (Utah Code 58-55-305) covers some projects under $7,000 including labor and materials, but work on a plumbing or electrical system must still be done by a licensed plumbing or electrical contractor, and work on a component such as a faucet, toilet, fixture, outlet or switch must be done by a licensed contractor or licensed journeyman. On January 1, 2027 the exemption moves to Utah Code 58-55-110, which leaves out any work on an electrical or plumbing system or a component of one.
