Online Application Process

The City of Arvada uses eTRAKiT for the Permit application process.


  eTRAKIT Application




Fees for these types of permits is a flat rate of $40.00 plus Use Tax. If two or more appliances are being installed, the fee is $60 plus Use Tax. Once the Use Tax has been paid, a copy of the permit can be presented to the material vendor who should then deduct any City Sales Tax on materials. If you are a contractor that submits their Use Tax to the City of Arvada Sales Tax division, Use Tax will be removed from the permit after review by the Building Division staff, proof of Tax Exempt status will be requested during the application process.

What is Use Tax 

Use tax is a tax that is assessed in lieu of sales tax. The Arvada use tax rate is the same as the sales tax rate, 3.46%. Building use tax is assessed on construction materials that are used in Arvada. The revenues from building use tax are utilized to fund additional city services related to construction growth.

The tax is computed on the total value of the project. The construction project valuation is based on statistical data relating to costs of similar projects or the actual contract price of a project. Although an individual may conduct the construction work themselves and may obtain materials at a discount or no cost to the project still results in increased value to the improvements. Consequently, use tax is calculated on the greater of the calculated or contract values.

The building permit fee and Use Tax are based on the total value of construction. Use the Permit Fee Table to generate your fee. Use Tax is 56% of the job value multiplied by 3.46%.
