Help Me Get Started . . .

Before you start your project, you need to know what regulations apply to your property and what factors may impact your project. You'll need to consider:

Historic Landmark Status

Any project that involves changes to the exterior of landmark structures or properties in historic landmark districts must be reviewed by Landmark Preservation staff before you begin. The appropriate zoning, building, curb cut, or revocable permits needed for the project will be issued only after design review has been completed and the project has been approved. To determine your property’s landmark status, use the DevelopDENVER tool to the right. Then, visit the Design Review web page for more information.


Building Code

Denver Building Code provides minimum standards for building in order to safeguard public safety, health and welfare. The permitting and inspection process ensures that all home projects meet these standards and that all dwellings are safe and habitable at the time of construction.

  • Landmark review - required for glass replacement and replacement of windows for properties in a local historic landmark district or in a designated Landmark structure.
  • #1R Construction Permit - required for replacement of windows when the size of the window changes and for any window or glass replacement on properties in a local historic Landmark District

For Landmark Certificate of Appropriateness:

If your property is historically designated or located in a historic district, you will need a design review of your project to obtain a Certificate of Appropriateness.  Visit the Design Review web page for more information. 

 

For Building Permit:

  • #1R Construction Permit - completed by the staff of Development Services
  • Site Plan
  • Framing Plan

 

For a Do-It-Yourself (DIY) Project:

  • Homeowners Exam for specific trade if completing the work yourself 
    (See DIY Projects for requirements and more information.)
  • Identification (i.e. Driver's License)

Estimate Fees

Building permit fees are based on valuation of the work to be completed including the labor and materials.  View the permit fee schedules to estimate the fees required for your project.

NOTE:  When a Same Day Review is required for the #1R Permit, a  "walk through" submittal fee of 20% of the valuation of the work to be completed with a $100.00 minimum will be charged in addition to building permit fees.

 

There is no fee for Landmark review.

For Landmark Approval:

Submit a design review application to Landmark Preservation.  The approval typically takes one to three weeks.  More complex projects or projects requiring Landmark Preservation Commission or Lower Downtown Design Review Board approval will take longer.

NOTE:  Obtain Landmark approval first before proceeding with other permits.

For Building Permit:

Same Day Review - Upon completion of Landmark design review and approval, when necessary, present all construction documents to the Development Services Counter for review by City staff.  Once review has been completed and all documents approved, including Landmark approval, permit will be issued.

 

All approved construction set of documents, permits and inspector signature card are to be available on site upon request.

Typical inspections for window replacement when structural changes are made include the following:

  • Exterior Sheathing
  • Rough Utilities (Electrical)
  • Frame
  • Exterior Lath
  • Insulation (Batt)
  • Drywall
  • Final Utilities (Electrical)
  • Final

 

NOTE:  The inspections listed above may vary depending on the complexity of your project.

Who Will Be Doing the Work?

Decide whether you plan to complete the project yourself or hire a licensed contractor to complete the job for you.

Do It Yourself

Do-It-YourselfYou may need to pass a Home owners exam  to demonstrate proficiency in specific trades in order to get a permit to do the work yourself. 

You will also need to meet a set of requirements established by the Denver Building Code and the Building Department Policy ADMIN 131.3 governing homeowner completed work.  This policy can be found on our Building Codes, Forms and Policies page. 

Contractor

Contractors Use the Contractor license search to see if your contractor has obtained a contractor's license from the City and County of Denver.
