State Plumbing Board: News

Occupational Licensing Town Hall Meeting - Feb. 23 

The Colorado Department of Regulatory Agencies (DORA), Division of Professions and Occupations (DPO) was awarded a grant by the Council of State Governments (CSG), National Conference of State Legislatures (NCSL) and National Governors Association Center for Best Practices (NGA Center) (“the Partners”), with the support of the US Department of Labor (USDOL), to participate in an Occupational Licensing Policy Learning Consortium (the Consortium).

The grant is not monetary in nature, but provides significant technical support to the eleven states selected by the Partners, as well as each state’s stakeholder groups, to learn about the following:

  • Best practices in occupational licensing;
  • Challenges and opportunities with streamlining occupational licensing in Colorado;
  • Unique approaches used in current licensing policies in Consortium states;
  • Policies that create unnecessary barriers to labor market entry.

DORA/DPO will host a Stakeholder/Town Hall Meeting to hear from legislators, a representative from the Governor’s office, and representatives from our Partners regarding this endeavor. The meeting will focus on the following five occupations: addiction counselors, barbers, cosmetologists, electricians, and plumbers.

Notice! Elbert County Permits & Inspections

As of January 1, 2017, the State of Colorado will no longer be providing plumbing and gas piping permits and inspections in Elbert County. The plumbing and gas piping permits in this area must be obtained from Elbert County.

Permits and Inspections for "Tiny Homes"

The growing popularity of the “Tiny Home” carries with it several non-resolvable issues for individuals purchasing one with the intent of residing in the state of Colorado. The homes contain electrical wiring, plumbing, and fuel gas piping which are all required to be inspected by one of three means listed in the summary below. Tiny Homes built in other states cannot be inspected as required by Colorado statute as the installations are already covered, therefore tiny homes are not eligible for connection to utility services such as electric, water, sewer, or fuel gas.


Tiny homes:

  • are units that are typically 400 square feet of space or less and mounted on a wheeled platform for mobility.
  • are constructed at an offsite manufacturing location (mostly out of state).
  • contain living areas for cooking and sleeping.
  • have electrical wiring and plumbing already installed.

The Colorado Revised Statutes for Electrical (12-23-116 C.R.S.) and for Plumbing (12-58-114.5 C.R.S.) require inspections for all all electrical, plumbing, and gas piping installations. These inspections must be conducted by:

  1. State Electrical or Plumbing Board inspectors; or
  2. Local Jurisdictional Authority Inspectors; or
  3. Certification by the Division of Housing pursuant to 24-32-3311 Colorado Revised Statues regulating manufacture/mobile home construction (these units bear a HUD or FHA certification data plate).

Any structure that is built without inspections #1 or #2 above during construction and is not certified by #3 above is not eligible for electrical, plumbing or gas permits, or inspections by state or local jurisdictional permitting agencies by current state law.


All plumbing, fuel gas piping and electrical installations are to be inspected and passed prior to connection of any utility services. As these units are already finished on the inside, making inspection impossible, "Tiny Homes" are not eligible for connection to utility services.

Plumbing Licensing Exams to Cover 2015 ICC Codes Starting July 6, 2016

Beginning July 6, 2016, all licensing exams for Master Plumbers, Journeyman Plumbers, and Residential Plumbers will be based on the 2015 Colorado Plumbing Code (2015 International Plumbing Code, International Residential Code).

New Plumbing Code and Rules in Effect

The 2015 Colorado State Plumbing Board Rules, Colorado Plumbing and Colorado Fuel Gas Codes are now effective for all plumbing and fuel gas installations inspected by state inspectors. These rules, which became effective on February 14, 2016, also contain provisions allowing the use of graywater in Colorado.

The 2015 Board Rules make several amendments to the 2015 IPC, IRC, and IFGC that contractors, plumbers and local jurisdictional authorities must be aware of. The revised Plumbing Rules are posted on the DORA website and can also be reviewed here: Colorado Plumbing Regulations Effective February 14, 2016.

As a reminder, per § 12-58-104(1)(l) C.R.S., local jurisdictions are required to "adhere to" or enforce the currently adopted code within 12 months of adoption by the Plumbing Board.

The new requirements for the Water Conditioning Equipment Contractor, Principle, and Installer registrations resulting from Senate Bill 15-202 become law as of April 1, 2016. This means water softeners may only be installed by Registered Water Conditioning Installers working for a Registered Water Conditioning Contractor. Included in the new law are requirements that every water softener installation be permitted and inspected.

The state plumbing license vendor will begin testing over the 2015 code at a yet-to-be-determined date. All tests prior to that date will continue to be from the 2012 code.

Water Conditioning Regulation Effective April 1, 2016

Effective April 1, 2016, the Colorado State Plumbing Rules will include changes related to the practice of water conditioning installation based on Senate Bill 15-202. Three new registrations have been created to allow non-plumbers to perform water conditioning installation.

Beginning April 1, 2016, these registrations must be in place prior to commencement of any water conditioning project.

Water Conditioning Installer:  Allowed to plan, lay out, and install water conditioning appliances in one-, two-, three-, and four-family dwellings, extending not more than two stores aboveground. In order to qualify for this registration, an applicant must possess and maintain an active Certified Installer (CI) certification from the Water Quality Association or an equivalent certification as approved by the Plumbing Board.

Water Conditioning Principal:  Allowed to do the same as a Water Conditioning Installer, but also includes responsibility for supervision of such work. In order to qualify for this registration, an applicant must possess and maintain an active Certified Installer (CI) certification and an active Certified Water Specialist (CWS) or Master Water Specialist (MWS) certification from the Water Quality Association or equivalent certification(s) as approved by the Plumbing Board.

Water Conditioning Contractor:  Undertakes or offers to undertake for another the planning, laying out, supervising, installing, or making of additions, alterations, or repairs in the installation of water conditioning appliances in one-, two-, three-, and four-family dwellings, extending not more than two stories aboveground. A permit and inspections will be required for all water conditioning installations, and can be obtained by the Water Conditioning Contractor. A Water Conditioning Contractor must employ a full-time water conditioning principal.

Licensed plumbers are still allowed to perform water conditioning installations, as before.

Please review the updated Colorado State Plumbing Rules (effective 4/1/16) to familiarize yourself with other aspects of water conditioning regulation. Applications for the three water conditioning registration levels will be available soon. Please monitor this website for updates.
