Project Guide for Bathroom Remodel

This guide is intended to give you an overview of the permitting process for a bathroom remodel. If your project only involves replacing (like-for-like) existing cabinets, countertops, flooring, plumbing and/or electrical fixtures, you do not need a permit.   

Permits are required when your project includes one or more of the following:

  • Alteration to the existing floor plan.
  • Structural changes that affect load-bearing walls and/or add or remove interior doorways.
  • New or rerouted ductwork.
  • New or relocated electrical or plumbing fixtures.

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. 


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


To view other considerations, see our Doing the Work Yourself page.
