Homeowners

Welcome, homeowners! Use these resources to learn about Denver’s development and permitting processes for existing and new residences. Find guidance on obtaining required permits, verifying contractor licenses, and accessing information on rental properties or homebased businesses.

Project Types

Single unit, duplex (two-unit) and Accessory Dwelling Units (ADUs)

These projects will go through the building, zoning, and sewer use & drainage permitting (SUDP) process and are generally designed under the International Residential Code (IRC).

For building and zoning permits, these projects are generally handled by Community Planning and Development’s single-family/ duplex residential review team with additional reviews from the Department of Transportation and Infrastructure’s (DOTI) sewer use & drainage permitting (SUDP) and Transportation teams, the Department of Public Health and Environment’s environmental quality team (for any new structure, addition or basement dig out) and the Denver Office of the City Forester.

Please note, Denver Parks and Recreation (DPR) Parks Planning team may also be required to review if the proposed project is adjacent to city owned park facilities.

These projects are submitted for review through a “Building Log” application in e-permits.

Permits related to existing units in 3-story townhomes, 4-story townhomes, condominiums and apartments

Most of these projects are governed by the International Building Code (IBC). The exception is 3-story townhomes, which are typically designed under the International Residential Code (IRC). Most projects in these structure types require registered design professionals to prepare and submit plans for permits, to confirm see Section 133.1 of the Denver Building Code. These project types are generally reviewed by:

• Community Planning and Development’s (CPD) commercial building review team (architectural/structural, mechanical/plumbing, electrical)
• Department of Transportation and Infrastructure’s (DOTI) sewer use & drainage permitting (SUDP) and transportation teams
• Denver Fire
• Zoning review is handled by the commercial zoning team within Community Planning and Development.
• The site design and neighborhood development team may review any additions or exterior changes if the proposed changes impact an approved site development plan. To see if your property has a site development plan, enter the address on this map.
