Submit application and plans to the Building Department at the City Office Building at 5355 West Herriman Main Street during our office hours of 7:30 a.m. to 5:30 p.m., Monday through Friday. Remember, the office is closed on State and Federal holidays.

Plan review will take approximately 10-15 working days, after which we may call with corrections that will need to be made to your plans. After the plans have been approved, we will email an invoice with permit fees. Payments may be made by check (made payable to Herriman City) or by Visa, Mastercard, Discover, or American Express.

Additions/Remodels vary in the inspections that are required. See Required Inspections – this will give you a list of the possible inspections that may be required for your project. If you are not sure which inspections apply to your project, be sure to contact us. Call the Building Department at (801)446-5327 at least one business day before you wish to schedule each inspection. You may ask for an hour block of time when there will be an adult to meet the inspector at the property. When the work is completed and all inspections are approved, be sure to keep the plans, permit and inspection reports with your house records.
