Permit Fees are based on the square footage being finished, but are not charged until all plan reviews are completed and approved (see Fee Calculation Form). Permit fees pay for reviews in the office as well as inspections which will need to be done at the property.
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 call with the amount of the permit. Checks should be made payable to Herriman City. Payments less than $1,000 can also be made with a Visa, Mastercard 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.
