How to Start a Plumbing Business in the USA: The Complete Guide
Plumbing is one of the most consistently in-demand trades in the USA – the Bureau of Labor Statistics projects 15% growth in plumbing jobs through 2032, well above the national average. Here’s how to build a plumbing business correctly.
Licensing: The Most Critical Step
Plumbing is licensed at the state level in all 50 states – this is more strictly regulated than most other trades. The typical pathway:
Apprentice → Journeyman Plumber → Master Plumber
- Journeyman license: 4-5 years of apprenticeship (or equivalent experience) + state exam. Allows you to perform plumbing work under supervision of or independently per state rules.
- Master Plumber license: Additional experience requirement (typically 2 years as journeyman) + a more comprehensive exam. Required in most states to pull permits, run your own plumbing company, and bid plumbing contracts.
Most states require a master plumber license (or working under one) to operate a plumbing business. Check your state’s licensing board.
Business Setup
Once licensed: LLC formation, EIN, business bank account, general liability insurance ($1M minimum), workers compensation (if hiring), and a commercial auto policy.
Join the Plumbing-Heating-Cooling Contractors Association (PHCC) – the primary US plumbing trade body, with chapters in every state.
Finding First Clients
Subcontract for GCs and established plumbing companies while building your reputation. Real estate investors need consistent plumbing for renovations. Property management companies need ongoing maintenance plumbing.
