Can You Be Your Own General Contractor in Colorado?

Colorado is one of the states where this question has a surprising answer, and the answer matters if you own land and are thinking about building on it yourself.

Colorado has no state general contractor license

There is no statewide general contractor license in Colorado. Licensing happens city by city and county by county, and each jurisdiction writes its own rules, its own exam, and its own insurance and bond minimums. Denver runs its own contractor classes. Colorado Springs, Aurora, Boulder, Fort Collins and Jefferson County each run separate programs. A contractor licensed in one of them is not automatically licensed in the next one over.

Two trades are the exception. Electrical and plumbing contractors are licensed at the state level, and that applies no matter which county you are building in.

For you as a landowner, the practical consequence is this: there is no single database you can check, and there is no single standard you have to meet. Everything routes through the building department with jurisdiction over your parcel.

Can you pull your own permit?

In most Colorado jurisdictions, an owner can pull an owner-builder permit for a home they intend to live in. The specifics vary, which is the whole point of this article. Call the building department for your county before you plan anything around it.

What does not vary is what you take on when you sign that permit. You become responsible for code compliance, for the schedule, for insurance, and for every subcontractor who sets foot on the site. The inspector is not there to teach you. The inspector is there to pass or fail the work.

What you actually save

A general contractor's fee generally runs somewhere in the range of fifteen to twenty-five percent of the build cost. On a four hundred thousand dollar project that is real money, and it is the reason people consider owner-building in the first place.

Be honest about what that fee buys, though. You are paying for relationships with subs who show up, for the knowledge of what happens next, and for someone who carries the liability when something goes wrong. When you owner-build, you are buying those things back from yourself with your own time and your own risk tolerance.

Where owner-builds actually go wrong

The failures are rarely about craftsmanship. Most owner-builders are perfectly capable of doing or supervising good work. The failures are about sequence and paperwork:

• Getting the order of operations wrong, so a sub has to come back a second time and you pay twice

• Signing a subcontractor agreement with no written scope, so "that was not included" becomes your problem and your cost

• Missing an inspection and having to open a wall back up

• Running out of money at drywall, because nothing in the original budget covered site work, soft costs, or the well

• Finding out your jurisdiction required something only after the concrete was already poured

Every one of those is an experience problem, not a skill problem. That distinction is worth sitting with, because it tells you exactly what kind of help is worth paying for.

Who should own-build, and who should not

Owner-building tends to work when you have genuine schedule flexibility, when you are comfortable making decisions under uncertainty, and when a delay costs you patience rather than money. It tends to go badly when you have a demanding job, a hard move-in date, and a construction loan with a clock on it.

There is no shame in either answer. The expensive mistake is deciding based on optimism instead of on an honest look at your calendar.

If you would not enjoy spending fifteen hours a week on this for a year, the general contractor fee is not an overcharge. It is a fair price for not doing that.
