Permit and Inspection Information

This online system was designed to allow homeowners and plumbing contractors and other non-plumbing contractors (gas piping, mobile home, and shower pan installers) to obtain plumbing permits, pay for them using a credit card, and request inspections via the Internet.

Online Permits System
 

-

A valid Colorado State Plumbing permit must be applied for and issued through this office prior to beginning work. All permits are valid for one year from the date the permit is issued.

A separate permit is required for each detached structure on the same property. Separate structures must be clearly indicated by name, letter or number if more than one exists on the same property Example: garage, studio, barn; building A, B, C; Building 1, 2, 3; etc.

A plumbing contractor or homeowner may obtain permits online. A plumbing contractor may not do work on a permit issued to a homeowner. Plumbing permits for all state inspected areas, public schools, and state buildings are issued and inspected by the Plumbing Board. Please use our online permit system.

A homeowner may install plumbing at their residence if they own the home and are living in it. The property cannot be for sale, resale, or rent. All work is required to be inspected under the currently adopted plumbing code. Homeowners, click here to download basic homeowner guidelines. Click here for guidelines for modular housing.

The International Plumbing Code (IPC), the International Residential Code (IRC), and the International Fuel Gas Code (IFGC) are the adopted codes used by the State of Colorado. Plumbing installations must comply with IPC, IRC, and IFGC requirements.

The state currently employs 9 inspectors who inspect in 26 counties throughout Colorado. All public schools and state buildings are inspected by state plumbing inspectors throughout the state. Click here to view a map of the state inspectors' territories.

In areas where the state currently does not inspect, you need to contact the local jurisdiction. Click here to view a list of the county jurisdictions.

The most efficient way to request an inspection is through the on-line permit system. Have the permit number and address at hand. Inspectors are responsible for setting their daily inspection schedule. Inspections should be requested no later than 3:00 p.m. the day before your inspection. To contact your inspector, refer to the Inspector list. Click here.

Important note: Please do not use your cellular phone to request an inspection. Cellular signals are not reliable, possibly resulting in an incomplete inspection request with delayed or no inspections.

Inspection Schedule Available On-line

  • After you request an inspection, the inspector will normally schedule this inspection within three days.
  • Once an inspection has been scheduled* by the inspector, you can access that information from your online account. View the specific permit to see if it has been placed on the schedule* for that day.
  • This information will be posted throughout the morning on the day of the scheduled* inspection, usually by 10:00 a.m.
  • Make sure that the inspection site is available and the installation is accessible to the inspector from 8:00 a.m. until 5:00 p.m.
  • Contact your inspector with updated driving directions, phone numbers, or access codes not listed on the permit. Do not fax this information the day of the inspection. Your inspector may not be available to receive that information.
  • To avoid re-inspection fees make sure that:
    • The address number is visibly posted at the driveway entrance of the jobsite.
    • That the job is ready for the inspection before you call to request an inspection.
  • No additional information regarding the inspection schedule is available through the website or Board office.
  • Inspections will not be performed on weekends or official holidays.

*Due to unforeseen delays, your inspector might not be able to complete the entire inspection schedule for that day.

Information Guidelines

Additional permit fee: This is required when: (1) the number of plumbing items indicated on the original permit does not coincide with what is installed at the residence, or (2) material costs and labor exceeds the original figure estimated for a commercial job.

Re-inspection fee: If an inspection is marked ‘rejected’ by the inspector, you may be required to pay a re-inspection fee before another inspection will be made.

Trim permit: If the permit expires after the rough-in inspection has been approved, a trim permit must be obtained and the required fee paid.

Permit extension: Permits may be extended one time for a period of six months. In order to receive an extension on your permit, you must notify the Denver office before the permit expires. You may contact the office at (303) 894-2300.

Request for a Code Variance: A variance to the code for a specific plumbing installation must be granted from the Board. Please completed and submit a variance request form to the Board for review.

Refund Policy

A refund may be allowed for a six-month period from the permit issue date as long as no inspections have been performed. The refund request may be submitted by email, fax, or mail to the Denver Office. The request must include:

  1. The permit number.
  2. Name of the permit applicant.
  3. Type of payment (if paid by check, include a copy of both sides of the cancelled check). Check refunds may take up to 45 days to process.
  4. Reason for the refund request (cancelled the job, property is not in the state’s jurisdiction, etc.)

An option to requesting a refund: A plumbing contractor may transfer an existing permit from one job address to another job address; however, a transfer is not allowed between contractors or from a contractor to a homeowner. For permits that qualify for a transfer, make sure that:

  1. The fee is the same amount, and
  2. No inspection has been made.

To transfer the existing permit to another address, mark the appropriate changes to the existing permit. Mail or fax the corrections to this office at the address, fax number, or email listed below. The changes will be made and a corrected copy of the permit will be made available.

Please contact this office with any questions on the above policy and we will be happy to help you apply for a refund or transfer your permit.
