Building Permit Fees

Fee determinations are based on a number of variables.

The Uniform Building Code mandates a fee formula based on the valuation of new structures. This formula considers the following 4 questions;

What will the use of the structure be?
What is the contract price of the project?
What is the square footage?
What is the quality of the construction?

Other variables which may apply are;

Will the structure be served by well & septic or sewer & water?
Will an encroachment permit be required?
Will fire fees or mitigation measures be required?
Will drainage review be required?
Where is the structure located? Some fees are based upon a district, such as school and traffic mitigation fees.

Other fees such as park fees are a fixed amount that we collect for each new living unit.

An Affordable In-Lieu Fee may apply to residential new construction. A similar Affordable In-Lieu Fee may apply to non-residential new construction. In some cases a Second Dwelling Unit or Ag Employee unit may eliminate the need to pay the Affordable Housing In-Lieu Fee.

Due to the complexity of these determinations, it is unwise to make assumptions until the full scope of a project is determined by PRMD Staff at the time an application is accepted.

Please do not fill in amounts on checks prior to application acceptance.

Although every effort is made to provide complete and accurate information on this website, users are advised to contact appropriate PRMD staff before making project decisions. This may involve contacting more than one section within PRMD (e.g. Building, Plan Check, Zoning, Well & Septic, etc.), since each section implements specific codes or ordinances which may affect your project.
