This guide is intended to provide you an overview of the permitting process for detached accessory structures such as a shed, pergola, gazebo, stand alone deck, pool house, playhouse, cabana, and outdoor fireplace.

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.

 



Zoning

Zoning establishes standards for things such as the size and location of structures and acceptable uses for your property. Before you begin construction, you need to be sure your project is in compliance with the Denver Zoning Code. Use the DevelopDENVER tool to the right to determine the zoning for your property. In the results, click on your zone district for descriptions and definitions; then, click on your neighborhood context for more information on zoning in your area.



Parkways

Any project that encroaches on a designated parkway setback will need to undergo parkways review. Certain parkways and boulevards are specifically designated by ordinance to preserve their unique character. Each Designated Parkway has its own right-of-way width and regulations of setback distance of structures and signs. If you are unsure if you live along a designated parkway or for your parkway’s specific regulations, enter your address into the DevelopDENVER tool at right. Look under “Designated Parkways” on the results panel on the left. If a specific parkway appears, click on the “Details” button for information on setbacks.



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.



Location of Utilities

When designing your project, you need to know where utilities are located. You cannot build over existing utilities. Before you dig, contact the Utility Notification Center of Colorado at 1-800-922-1987 or 811 to mark underground utilities for your project.


Location of Existing Sewer Lines

If you plan to build a new structure over or within 2 feet of the existing sanitary sewer, you will need to replace the sanitary sewer with approved materials. A plumbing contractor can help you locate the sewer lines on your property. Visit Wastewater Sewer Use and Drainage Permit (SUDP) for application, guidelines and other specific information. Contact the Department of Public Works at 303-446-3759 for additional details.

Listed in the order they must be obtained. All permits must be in hand and at site before work may begin.

  1. Current City of Denver Contractor’s License Affidavit of Requirements for Owner-Occupier Permits (see Issuance of Owner-Occupier Permits (PDF) for more information). 
  2. Landmark Certificate of Appropriateness – if the project is in a designated historic district or landmark property. Visit the Design Review web page for more information.
  3. Parkways Review – if your property is along a designated parkway and the project encroaches on the parkway setback
    You will need: A completed Parkway Exception Request form and a site plan that includes property lines, parkway setback from property line, proposed type, location and dimensions of encroachment into parkway setback, location of existing residence on property and labeled streets. To get a copy of the form and additional information, contact parkways@denvergov.org.

The above must be in hand before you apply for the following:

  2. #1R Building Permit (Same Day Residential Review) – if you are building a covered structure that is over 8 feet in height and with 120 square feet of projected roof area OR if you are building an uncovered deck of any size that is 30 inches or more above grade
    You will need:
    - Foundation Plan including details on construction of the piers
    - Survey - required if construction is within 3 feet of the property line
    - Framing Plan, including size and spacing of post and beams
    - Roof framing

  3. #2 Roofing Permit (Quick Permit), including information on the number and type of shingles
  4. #3 Electrical Permit (Quick Permit), if electricity is installed
  5. Wastewater Sewer Use and Drainage Permit (SUDP) (Plan Review)
    Click link for application, guidelines and other information
    You will need a utility site plan that includes the following:
    • Location of structures in reference to property lines
    • Sewer locations
    • Pipe sizes
    • 2-way cleanouts
    • Material for all existing and proposed structures from point of connection to the structure to the main
    • Water line locations with sizes
    • All existing and proposed underground and storm water/sewage drainage
    NOTE: Wastewater does require sewer replacement with approved material for any structure being built over or within 2' of the existing sewer line. Wastewater does require that historic storm drainage be maintained and not directed to adjacent properties or across public sidewalks. If property is in a floodplain, additional submittal requirements apply.
    Visit the wastewater permits page for application, complete submittal requirements and guidelines, and other information.

SUDP application and materials may be submitted by email (wastewaterpermits@denvergov.org), online via e-Plan or in person at the Development Services Permit Counter (sign in online or at the kiosk for SUPD).

#2, #3 and #11 permit applications may be downloaded and filled out before they are submitted.

Zoning, #1R, #2, #3 and #11 permits may be applied for at the counter on the same day.

Sign in online once for zoning and #1R permits (Residential Same Day Review) and once for all Quick Permits. 

Estimate Fees
Zoning and Building permit fees are based on valuation of the work to be completed including the labor and materials. 

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. 

For Wastewater SUDP, there is a $100 application fee plus additional fees may apply.  The fees change yearly. 

View the permit fee schedules to estimate the fees required for your project.

There are no fees for Landmark or Parkways review.

Typical inspections for the construction of detached accessory structures include the following:

  • Footing
  • Exterior Sheathing
  • Exterior Lath
  • Drywall
  • Rough Utilities (Electrical)
  • Frame
  • Roof
  • Final Utilities (Electrical)
  • Final Construction
  • Wastewater inspection for replacement of sewer lines
    • Permit indicates sewer replacement when structure is over the sewer line or within 2 feet of the existing sewer line.
    • You may need to contact a plumbing or sewer contractor to determine if structure is over the sewer line.  The City only has location of the main lines, not the location of the sewer on private property. 

 

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

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.
