Roof permits and any other quick permits involving exterior work in landmark or historic districts cannot be issued online via e-permits. For these locations, submit via email or in person after receiving approval from Landmark Preservation.

How to apply

For minor work requiring quick permits but introducing little to no visible change to a historic structure or property:

• Email the Landmark Quick Review application form (PDF) to Landmark Staff at landmark@denvergov.org. Landmark quick review applications are typically processed within 1 business day.  
• Then, submit your quick permit application (located in the drop-down menus below) to quickpermits@denvergov.org.

Quick review approvals may be issued by Landmark Preservation staff for like-for-like replacement of the following existing exterior features providing that the applicable design guidelines and standards are met:

• rear yard decks and porches (must demonstrate no change in size, height, materials and ornament)
• rear yard fences (no change in height, openness and materials)
• 1-2 flat profile skylights
• sheds not on foundations (less than 100 square feet)
• exterior HVAC work (no change in geometry, demand or materials)
• simple exterior mechanical work
• reroofing (no change in materials)

For more significant alterations, visit the Landmark Design Review webpage for guidelines and instructions on how to apply.
