Residential Permits

COVID-19 Information

  1. Per public health guidelines, access to Town buildings is closed. However, staff is still available - many of them remotely - to provide necessary services. Here's how to work with us online.

    Building Counter and Permitting

    • Over-the-counter permits are still available through the Town’s permitting website
    • Electronic submittals through TRAKIT are required for all residential and commercial projects. All submitted documents must be in PDF format.
    • The Town Building Division will not be scheduling any face-to-face meetings. However, we do have the ability to host remote meetings. If interested, please contact 720-733-3527.
    • There will be no interruption in the issuance of Certificates of Occupancy during this temporary closure.

    Building Inspections

    • Until further notice, inspection services will continue for new residential, commercial and multi-family construction.
    • Building Inspections related to occupied residential dwelling units, that require the inspector to go inside, will be suspended until further notice.
      Please Note: In an effort to provide inspections for interior residential projects we will attempt to perform remote inspections using FaceTime, Google Duo, and Skype. These inspections must be pre-scheduled and coordinated with our building and electrical inspectors. The contractor (general contractor for building, mechanical and plumbing inspections; electrical contractor for electrical inspections; or homeowner that performed the work must be onsite to walk the project while the inspector remotely performs the inspection.) Please schedule remote inspections through TRAKIT. An inspector will contact you within 24 hours.
      Please also note: For final electrical inspections a plug tester will be required
    • Residential inspections for projects on the exterior of occupied dwelling units, such as decks, roofs and photovoltaic inspections (excluding attic) will continue.
    • This suspension does not allow work that requires inspections to be covered or concealed until such time that it can be inspected and approved.

Homeowners may act as their own contractor for residential additions, alterations or repairs. Homeowner Affidavit - this form is required for homeowner's performing their own work and acting as their own general contractor.

Submitting applications

Temporary erosion and sediment control (TESC)

As of July 1, 2019, changes to the erosion control program for residential building are in effect. Here are a few key items that will help make that transition process run smoothly. 

Residential developments that must comply with the new vertical residential TESC Permit requirements are:

  • All sites without active building permits as of July 1, 2019
    • No building permits will be released without an approved TESC Plan and Permit in place
  • Sites with 5 acres or more of active building / DESC permitted sites and vacant lots remaining
    • The Town will continue to allow building permits to be issued for 30 days once the required Vertical Residential TESC items have been submitted for review

Residential bonding for final grade

When final grade cannot be achieved due to weather, the permittee may submit the completed form on page 2 of the Residential Bonding Policy for final grade to request approval to post a Fiscal Surety. Bonds will be approved only in cases where final grade cannot be established because of adverse site conditions caused by weather at the time of the final inspection. Bonds for reasons other than weather-related site conditions will be considered on a case-by-case basis and are subject to denial. Temporary sediment controls are required at all times regardless of weather conditions.
