Frequently asked questions
P200 and P201 plumbing contractor questions
Is a P200 license the same as a master plumber license?+
No. A master plumber license belongs to an individual. P200 is a contractor classification issued to a business. The business needs an eligible master plumber qualifier and must complete the contractor application requirements.
What is a P200 plumbing contractor license in Utah?+
P200 is Utah’s General Plumbing Contractor classification. Current Utah law describes general plumbing work around sanitary conditions, safe water, waste removal, and gas systems, while the current contractor rule adds specified connections to main water, sewer, and gas lines and includes the P201 scope. DOPL decides whether a proposed operation fits the classification.
What is a P201 plumbing contractor license in Utah?+
P201 is Utah’s Residential Plumbing Contractor classification. Its scope is limited to residential buildings under the current definitions. Utah law defines a residential building as a single- or multiple-family dwelling of up to four units.
What is the difference between P200 and P201?+
P200 is the general plumbing classification and includes the residential P201 scope under the current rule. P201 is limited to plumbing work in residential buildings within the current statutory definition. Confirm the classification with DOPL when the business will perform mixed residential, commercial, industrial, utility-connection, or site work.
Does the owner have to be a master plumber?+
Not necessarily. The current contractor application allows the proposed qualifier to be either an owner of at least 20% or a W-2 employee in a management position. The plumbing qualifier must hold the master license DOPL accepts for the classification and exercise material authority in the business.
Can an employee qualify a plumbing contractor business?+
The current application provides a route for a W-2 employee in a management position to serve as qualifier. The person must meet the master-plumber requirement, accept the qualifier responsibilities, and have real authority in the contracting business.
Does the plumbing qualifier need to own 20% of the company?+
Twenty-percent ownership is one route shown on the current qualifier affidavit. The other route is a W-2 employee in a management position. An informal arrangement with a plumber who has no qualifying ownership or W-2 management role does not match either option on the form.
Can a journeyman plumber qualify a P200 or P201 business?+
The current contractor application and DOPL classification materials say plumbing classifications require a master plumber qualifier. A journeyman license by itself should not be treated as satisfying that requirement.
Can a residential master plumber qualify a P201 business?+
DOPL separately licenses residential master plumbers, but its current public contractor page, application, and classification chart state that P200 and P201 require a Master Plumber. Because that wording is not classification-specific, a P201 applicant proposing a Residential Master Plumber should obtain direct written confirmation from DOPL before relying on that path.
Do P200 and P201 applicants take a 30-hour pre-license course?+
The current application lists a 25-hour pre-licensure course plus a 5-hour Business and Law course for P200 and P201 initial applicants, subject to the alternative course paths listed on the current form.
When should a plumbing contractor buy insurance for the application?+
First confirm the classification, qualifier, experience, course, exam, entity, and worker setup. Insurance becomes an application-document step once the legal business name and license path are stable. Recheck the current liability limit before binding because DOPL’s live page and current application presently conflict on the aggregate amount.
What documents are required if the plumbing company has no employees?+
The March 27, 2026 contractor application directs a business with no employees and no intent to hire employees to submit a Workers’ Compensation Coverage Waiver from the Utah Labor Commission. Waiver eligibility is decided by the Labor Commission.
What changes when the company hires a plumbing helper or apprentice?+
A helper or apprentice working for the business normally moves the application away from the no-employee waiver path. The current form asks an employer for a workers compensation certificate, unemployment registration, and a Utah withholding account, or the applicable PEO documentation. Plumbing licensing and supervision rules apply separately.
