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
If your property is in a local historic landmark district or is a designated landmark structure, the Landmark Preservation staff must complete a design review of your project before you begin. Use the DevelopDENVER tool to the right to determine your property’s landmark status. Changes to the exterior of landmarked properties require approval from Landmark Preservation prior to the issuance of appropriate zoning, building, curb cut, or revocable permits. Visit the design review web page for more information.
Zoning establishes standards for things like 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 Denver's Zoning Ordinance. Use the DevelopDENVER tool to the right to determine the zoning for your property. Once you've found how your property is zoned, you should look up your zone district in the Denver Zoning Code to see what that means for you.
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, use the DevelopDENVER tool to the right to determine your status.
Denver Building Code provides minimum standards for building in order to safeguard public safety, health and welfare.
Location of Utilities
When designing your project, you need to know where utilities are located. You cannot build over existing utilities. Contact the Utility Notification Center of Colorado to mark underground utilities for your project. Call 1-800-922-1987 or 811 before you dig.
Location of Existing Sewer Lines
A plumbing contractor can help you locate the sewer lines on your property. 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.
Contact the Department of Public Works at 303-446-3759 for more details.
NOTE: Wastewater Management defines an ADU as any structure that has either a bathroom or kitchen or is used as habitable living space.
Transportation review and approval is needed whenever you are changing the location of your driveway or proposing any improvements within the Right-of-Way (ROW) such as changing the curb cut. All projects performed in the City Right-of-Way must be performed in full compliance with the City Charter, Ordinances, permitting processes and all other applicable standards, specifications and requirements of the City and County of Denver.
