Owner-Builder in Utah: Can You Be Your Own General Contractor?

Building your own home in Utah? The owner-builder exemption allows homeowners to act as their own general contractor under certain conditions. Here's everything you need to know.

What Is the Owner-Builder Exemption?

Utah law allows property owners to build or improve structures on their own property without a contractor's license, provided:

1. The structure is for your own personal use
2. You are not building to sell (speculative building requires a license)
3. You obtain all required building permits
4. All subcontracted work is performed by licensed professionals

When Does It Apply?

The exemption covers:

• Building a personal residence on your own land
• Major renovations or additions to your home
• Accessory structures (garages, workshops, ADUs for personal use)

It does not cover:

• Building homes to sell (flipping)
• Commercial construction
• Work for hire on other people's properties

What You Still Need

Even as an owner-builder, you'll need:

1. Engineer-Stamped Site Plan

Most Utah counties require an engineer-stamped site plan before issuing a building permit. This shows your property boundaries, proposed structure location, setbacks, utility connections, and grading plan. Peaking Engineering & Construction provides site plans for owner-builders throughout Utah — call 801-791-4095 for a free consultation.

2. Building Permits

Apply through your local building department. You'll need:

• Site plan
• Architectural drawings or house plans
• Structural engineering (for the foundation and framing)
• Energy compliance documentation

3. Licensed Subcontractors

You can manage the project, but licensed subs must do:

• Electrical work (licensed electrician required)
• Plumbing (licensed plumber required)
• HVAC (licensed HVAC contractor required)
• Gas piping (licensed professional required)

4. Inspections

You must pass all required inspections at each phase:

• Foundation/footing
• Framing
• Rough mechanical (electrical, plumbing, HVAC)
• Insulation
• Final

Finding the Right Subcontractors

As an owner-builder, your success depends on hiring reliable subs. Here's how to find them:

1. Use VegaBuilds — post your project and specify you're an owner-builder. Contractors who are comfortable working with owner-builders will respond.
2. Check licenses — verify every sub through Utah DOPL
3. Get insurance certificates — every sub should have general liability and workers' comp
4. Get detailed bids — compare scope, materials, and timeline

Critical Steps for Owner-Builders

Site Work and Engineering

Before you break ground, you need proper site work. This includes:

• Topographic survey — know your land's elevation and features
• Geotechnical report — soil conditions affect foundation design
• Septic system design (if not on city sewer) — Peaking Engineering designs and installs septic systems
• Utility coordination — water, sewer, power, gas connections

Excavation and Foundation

• Hire an experienced excavation contractor for site prep
• Foundation design should be engineer-stamped
• Don't skip the compaction testing

Scheduling

The hardest part of being an owner-builder is scheduling. You need to coordinate:

• Excavation → Foundation → Framing → Roof → Rough mechanical → Insulation → Drywall → Finish work

Each trade depends on the one before it. Delays cascade quickly.

Is It Worth It?

Owner-building can save 15-25% on construction costs, but it comes with significant time commitment and risk. It works best when:

• You have construction knowledge or experience
• You have flexible time to manage the project
• You have reliable subcontractor relationships
• You're organized and detail-oriented

If you're unsure, consider hiring a general contractor for the overall management while staying involved in decisions. A good GC earns their fee.
