The Building Division is excited to announce they will be accepting credit cards starting January 3rd 2012. Payments must be made in person (no credit cards will be taken over the phone or via fax) and will be accepted for contractor registrations, reinspection fees and some building permits fees.

Building permit fees may be paid via credit card with the exception of:

  • Utility water/sewer tap permits
  • Fire department permits
  • New residential or commercial permits
  • Tenant finish permits (remodel permits may be paid with credit cards)

Please contact the building division with any questions you may have.

Building Permit Fees

Did you know that you can present a copy of a building permit when purchasing construction materials for your permitted project so that the local sales tax will NOT be charged?  The following link has further information:

Building Permit Use Tax Information 

Please be aware that payment of tap fees is required at the time the Building Permit is issued. As already required, if the building use changes in the future, tap fees will be recalculated and additional tap fees may be due. Be sure to install and activate water meters as soon as possible to lock in the tap fee. 

Water/Sewer Tap Fees

Tap fees are charged to new construction to cover costs related to its impact on the City’s utilities.   Current customers do not pay tap fees.  Westminster’s water tap fee includes the following components:

  1. The Infrastructure or Treated Water Investment Fee is set to recover an equitable portion of the value of the City’s infrastructure required to meet the demand of the new customer.  The infrastructure includes all components of the utility system required to divert, treat and distribute water to customers.  Infrastructure tap fees are calculated based on fixture count and resulting meter size, which is the best determination of projected peak demand on the infrastructure system.
  2. The Water Resources Fee is set to recover the value of the City’s water supplies developed to meet the demand of the new customer.  Water resources are calculated in terms of Service Commitments (SC).  One SC is equal to 140,000 gallons of annual use, which is the projected use of one new single-family home.  For those other than single-family homes, multiples of service commitments are purchased based on a projected volume of use.

Periodically the City increases the cost of the infrastructure portion of the water tap fee to ensure that new users are paying an equitable portion of the overall costs to maintain and improve the water system. A recent study determined that the infrastructure portion of the water tap fee should be increased to address the water system’s replacement cost.   This is based on the value of the improvements made to the system and the increase in the replacement costs for the rest of the system since the infrastructure fee was previously set.

The water resources portion of the tap fee is based on the current market value of the water resources owned by the City.  Recent water purchases are used as a basis for determining the current market value.  Water purchases are valued in terms of the cost per acre foot (AF) of reliable annual water delivery.  Currently, Westminster’s tap fee is based on a water value of $17,000 per AF.   Since this value was established, in 2006, the market for water rights in the Front Range of Colorado has become even more competitive.  The current market value of Westminster’s water resources ranges up to $30,000 per AF.  Westminster has chosen a mid-range water resources value of $25,000 to base the water resources component of water tap fees on.

In December of 2013 City Council voted to implement the following water tap fee increases effective January 1, 2014.  Water tap fees will be increasing to $20,836 per single family equivalent reflecting the increase in the cost of water to the City and the increase in the value of the City’s water infrastructure since 2006, the last time water tap fees were adjusted based on system value and current costs.

Irrigation tap fees will be increasing proportionately in 2014.

Sewer tap fees will also be increasing to $5,554 based on an increase to the City from Metro Wastewater
