What Can a Handyman Do vs a Licensed Plumber in Colorado?

In Colorado, handymen can legally replace fixtures like faucets and toilets in place, but Colorado Revised Statutes CRS 12-155-122 requires a licensed plumber for any work involving new pipes, permits, or fixture additions—with violations classified as a class 2 misdemeanor.

Key Takeaways

• Handymen can replace faucets, toilets, and showerheads in same location with existing connections under Colorado law.
• Water heater replacement, new supply/drain lines, and sewer work require licensed plumber and permit in Colorado.
• Unlicensed plumbing work is class 2 misdemeanor under CRS 12-155-122; insurance claims may be denied.
• Colorado homeowners can perform plumbing on primary residence only—not rental or investment properties.

It's a fair question. You've got a leaky toilet, a loose faucet, or an aging water heater, and you're wondering whether you need to hire a licensed plumber or if your handyman can take care of it. The answer depends on exactly what the job involves. Colorado law is pretty clear on what a handyman can do vs a licensed plumber, and knowing the difference protects your home, your wallet, and your insurance coverage.

Does Colorado require a license for plumbing work?

Colorado is not a state where you can legally do plumbing work without a license, at least not professionally. Under Colorado Revised Statutes, anyone performing plumbing work as a trade must hold a valid plumbing license issued by the Colorado State Plumbing Board. Apprentices can work on plumbing, but only under direct supervision of a licensed journeyman or master plumber.

A handyman operating without a plumbing license who does work that crosses into licensed territory is breaking state law. Under CRS 12-155-122, performing unlicensed plumbing work is a class 2 misdemeanor. That's not just a risk for the contractor, it creates real problems for you as the homeowner if the work ever needs to be inspected.

What plumbing work can a handyman legally do in Colorado?

Colorado does give unlicensed handymen room to operate on cosmetic and like-for-like fixture work. The line the law draws is this: connecting a new fixture to existing pipes is generally fine. Moving or modifying pipes is not.

Things a handyman can typically do:

• Replace a faucet in the same location with the same connection type
• Swap out a toilet without changing the drain or supply lines
• Install a new showerhead on an existing shower arm
• Replace a garbage disposal connected to existing drain plumbing
• Fix a running toilet (flapper, fill valve replacements)

The common thread: the pipes are staying exactly where they are. No permit is needed, no new routing, no new lines.

What plumbing work requires a licensed plumber in Colorado?

As soon as a job moves beyond swapping a fixture in place, you're in licensed territory. A licensed plumber is required for:

• Water heater installation or replacement (requires permit and inspection)
• Running new supply or drain lines anywhere
• Adding a bathroom or kitchen fixture that doesn't already exist
• Re-piping any portion of the house
• Sewer line work or repairs underground
• Anything that requires pulling a permit

The reason the line is drawn here is that permits require a licensed contractor to pull them. If your handyman can't legally pull a permit, and the job legally requires a permit, you're already in a bad position before work even starts.

Can homeowners do their own plumbing in Colorado?

Colorado law does allow homeowners to do plumbing work on their own primary residence. You can pull your own permit, do the work yourself, and have it inspected. The key word is primary, meaning the home you actually live in. You can't legally do this on rental properties or homes you don't occupy.

Most homeowners who try DIY plumbing beyond basic fixture swaps quickly find out why licensed plumbers exist. Drain slope, venting requirements, and pipe sizing rules are not intuitive, and mistakes show up at the worst times.

Why does hiring unlicensed plumbers create problems for homeowners?

Hiring an unlicensed person to do work that requires a license creates real exposure for you:

Insurance claims can be denied. If a pipe installed by an unlicensed contractor fails and floods your home, your insurance company will look at who did the work. Unpermitted, unlicensed work gives them grounds to reduce or deny the claim.

You can't sell the house cleanly. Home inspectors and buyers' agents know what to look for. Unpermitted plumbing that surfaces during a sale negotiation often results in price reductions or required repairs at closing.

Safety. Improper venting causes sewer gas to back up into living spaces. Incorrect drain slopes cause chronic clogs and backups. Undersized pipes cause pressure problems. These aren't hypothetical.

A Simple Way to Think About It

Handyman: turning off the shutoff valve, disconnecting the old, connecting the new, turning the water back on. Same spot. Same connections.

Licensed plumber: anything where water or drain pipes are being modified, moved, added, or replaced. Anything that requires a permit.

If you're not 100% sure which category your job falls into, that's a good reason to call a licensed plumber for the estimate. Most will tell you quickly whether a permit is involved, and many offer free estimates so you know what you're looking at before committing.
