Do I Need a Permit for a Patio Cover or Pergola in Utah?
Quick Answer
Solid roof covers yes. Open-lattice pergolas may be exempt.
Utah-specific rules
Adopted code: 2021 IRC, adopted statewide under Utah Code § 15A-2-103 (in force through June 30, 2026; the IRC edition does not change on July 1, 2026).

Solid vs. Open
Solid-roof patio covers (those that keep rain off) almost always require a building permit. They are treated as a building addition and count toward lot coverage. Open-lattice pergolas — where slats allow rain through — may be exempt in some cities, but rules vary. When in doubt, call your city.
Attached vs. Detached
Patio covers attached to the house require a ledger connection (similar to a deck), which inspectors scrutinize closely. Detached structures have simpler attachment requirements but still need proper footings and must meet setbacks.
Lot Coverage
Solid-roof patio covers count toward your lot's maximum building coverage (typically 40-50% in residential zones). If your lot is already near the limit, you may not be able to add a patio cover without a variance. Open-lattice pergolas often do not count toward coverage.
Footings
Like decks, patio cover footings must extend below the local frost line — the required depth varies by climate and elevation, so confirm the depth your city requires. Posts must be properly anchored to the footings with approved hardware — not just set in concrete.
Bottom Line
Solid-roof = permit required. Open-lattice = maybe exempt. Either way, check setbacks and lot coverage before building.
