Building Permit Fees

The cost of a building permit includes, but is not limited to: the building permit fee, sales tax and plan review fees. If you need additional information regarding building permit fees or assistance calculating fees, please contact Building Inspection at (303) 651-8332 or

To view other fee schedules, please visit the pages created for each type or category: Miscellaneous Inspections and other Fees, Impact and Development, Electric Fees, and Water Fees.

Permit fees are based on the project valuation. Building Inspection calculates this based on the project’s gross floor area (square feet) or scope of work multiplied by the applicable ICC “Building Valuation Data” or RS Means “Building Construction Cost Data.”

The ICC “Building Valuation Data” and RS Means “Building Construction Cost Data” are reviewed and adopted Longmont City Council annually. The “Building Valuation Data” is developed by the International Code Council (ICC), updated and published semiannually in the their quarterly “Building Safety Journal.” “Building Construction Cost Data” is updated and published annually by RS Means. Both ICC and RS Means provide “average” construction costs to assist jurisdictions in estimating the value of a project.

  • The building permit fee is calculated by applying the determined project valuation or construction cost to the Primary Fee Table of the Fee Schedule.
  • Sales tax is calculated by multiplying 50% of the determined project valuation, by the current city and county tax rate of 4.515%.

***Effective January 1, 2018, City sales tax increased from 3.275% to 3.53%.  Total City and County sales tax charged on a building permit will be 4.515% .*** 

  • The plan review fee is determined by applying the Plan Review Fees of the fee schedule to the project. 
  • Other fees may be applicable based on the type and scope of the project. Please consult with a Building Inspection Division Permit Technician for assistance in determining the correct total building permit fees due.
  • The building permit fees can be paid by cash, check or credit card (Visa, Mastercard, American Express, or Discover).
  • Up to $2,000 maximum per credit card transaction.  Transactions cannot be split to meet this requirement.
