Can I Be My Own General Contractor in Oregon?
Oregon allows property owners to manage their own construction projects - but it comes with real legal obligations, financial risks, and employer responsibilities most people don't expect.
As your own GC, you must verify every subcontractor's CCB license. Check any license free.
Can I be my own general contractor in Oregon?
Yes. Oregon law allows property owners to act as their own general contractor to build a new home or make a substantial improvement to a residence they own and intend to occupy. You do not need a CCB license to manage your own project. However, before any building permit can be issued, you must sign a Property Owner Statement Regarding Construction Responsibilities (ORS 701.325).
This statement acknowledges that you understand your legal obligations as an owner-builder - obligations that most homeowners significantly underestimate. The rest of this guide explains what those obligations actually are.
The owner-builder rule
The owner-builder exemption only applies to property you own and intend to reside in. It does not apply to investment properties, properties you intend to sell, or commercial projects. If you build or substantially renovate a home and sell it within a certain period, you may still face liability for construction defects.
Can I legally build my own house in Oregon without a contractor?
Yes - Oregon law explicitly permits this. You do not need to hire a licensed general contractor to build your own home, and you do not need a CCB license yourself. The key conditions are:
- You must own the property where construction takes place
- You must intend to reside in the home upon completion
- You must sign the Property Owner Statement (ORS 701.325) before permits are issued
- Any workers you hire who are not CCB-licensed subcontractors may be considered your employees under Oregon law - with all the employer obligations that entails
- All licensed trade work (electrical, plumbing, mechanical) must be performed by contractors holding the appropriate Oregon licenses
The exemption does not apply if you build the home and immediately put it on the market. Oregon courts have held that the owner-builder exemption is intended for genuine owner-occupants, not for speculative construction.
Do I need a CCB license to act as my own GC?
No. The owner-builder exemption means you can legally manage your own residential construction project without a CCB license. However, anyone you hire to perform the work - roofers, framers, electricians, plumbers - must hold valid CCB licenses for their respective trade. You cannot hire unlicensed workers and call them subcontractors to sidestep employer obligations.
What training or knowledge do you need to be your own GC?
Oregon requires no formal training or certification to act as your own general contractor. But the absence of a requirement doesn't mean you don't need knowledge. Successful owner-builders typically understand:
Construction sequencing
Knowing which trades come in what order - foundation, framing, rough-in plumbing/electrical/mechanical, insulation, drywall, finish work - and how delays in one phase cascade into the next.
Permit and inspection process
Which inspections are required at each phase, how to schedule them with your local building department, and what happens if an inspection fails - work stops until corrected.
Subcontractor management
How to vet, hire, and coordinate multiple licensed subcontractors. How to verify their CCB licenses, request certificates of insurance, and manage payment schedules tied to milestones.
Oregon building codes
The Oregon Residential Specialty Code (ORSC) governs residential construction. You don't need to memorize it, but you need to know when to ask questions - and to understand that code requirements can affect cost estimates significantly.
Most successful owner-builders have prior construction experience, a background in project management, or significant time to dedicate to learning on the job. If you're starting from zero, the Oregon Builder's Guide and local community college construction courses are practical starting points.
Your legal obligations as an owner-builder
When you act as your own general contractor and hire workers who are not CCB-licensed subcontractors, those workers may be classified as your employees under Oregon law. As an employer, you are responsible for:
Workers' Compensation Insurance
Oregon's Workers' Compensation Law requires employers to carry workers' comp for all employees. If you hire unlicensed workers and one is injured on your job site, you may be liable for all medical and disability costs - even if you didn't formally hire them as an employee. This is one of the most significant financial risks of owner-building. Contact the Workers' Compensation Division at 800-452-0288 for information on obtaining coverage.
Payroll taxes - state and federal
As an employer, you must withhold Oregon income tax and pay Oregon unemployment insurance tax on employee wages. You must also withhold federal income tax and Social Security tax. Oregon requires a Business Identification Number (BIN). Register at the Oregon Business Registry or call 503-945-8091. For a federal EIN, apply at irs.gov.
Liability insurance
Your standard homeowner's policy may not cover construction activity on your property. Contact your insurance agent to ensure you have adequate coverage for accidents, property damage, and injuries to workers not covered by workers' comp. Common incidents - a falling tool, paint overspray on a neighbor's car, water damage from a pipe puncture - can be costly without proper coverage.
Permits and code compliance
As the permit holder, you are responsible for scheduling all required inspections at the right project stages and for resolving any code violations found. Building officials will not approve the next phase of work until required inspections pass. If you miss an inspection or the work fails, the cost of remediation falls on you.
Verifying subcontractor licenses - your responsibility
The safest approach for owner-builders is to hire only CCB-licensed subcontractors for all trade work. Licensed subs carry their own workers' comp and liability insurance, removing most of the employer liability risk from you.
As an owner-builder, you are responsible for confirming that every subcontractor you hire holds a valid CCB license. You can verify any contractor's license, bond, and insurance status at CCB Lookup before they set foot on your job site. You can also browse licensed contractors by county to find candidates in your area.
Is it worth it to be your own general contractor?
Potential advantages
- Save 10–20% on GC markup over subcontractors
- Direct control over material and trade selection
- Real-time visibility into every aspect of the project
- Ability to make changes quickly without going through a middleman
- Can use your own labor for non-permit work
Real risks and costs
- Workers' comp and employer tax obligations
- Requires significant time on-site daily
- No access to a GC's established subcontractor relationships
- Scheduling mistakes can be expensive (idle crews, delayed inspections)
- Code compliance responsibility is entirely yours
Owner-building works best for people with construction or project management experience, significant available time, and a tolerance for complexity. For most homeowners, the savings don't justify the risk. For experienced builders or contractors who are building their own home, it can make strong financial sense. Review the most common hiring mistakes before deciding which path to take.
