What it is

A part-time business for a licensed plumber with a day job. You take on small jobs like fixture replacements, leak repairs and drain clearing, using your own tools and truck or car.

Your first three steps

  1. Read your employment contract and check it allows outside work, and confirm your license lets you work for yourself
  2. Register a simple business with your state or city, get an EIN, and take out general liability insurance
  3. Set weekend availability, post it on a neighborhood app or local group, and take your first few jobs from people nearby
Who pays

Neighbors, friends of customers, landlords with a few rentals and small property managers who need work done outside business hours.

How it makes money

Hourly rate or flat price per job, with parts at cost plus a margin. Keeping to a small number of booked jobs each week keeps it manageable.

Questions people ask

How much does it cost to start a plumbing side business?

Estimates suggest startup costs typically around $1,000 to $5,000, depending on tools, vehicle and insurance. Monthly revenue is typically estimated around $800 to $4,000, depending on how many jobs you fit around your day job.

Can I do plumbing side jobs with my current license?

Some states need the license holder to be a master or contractor to work independently, so check your state board. Also check any employer non-compete or moonlighting clauses, and local permit rules for water heaters and repiping.

Do I need my own insurance for side jobs?

Check general liability insurance, since an employer's cover will not protect your own jobs. Estimates suggest as little as 8 hours a week, and burnout from physical work on top of a full-time job is worth planning for.
