Can I Be My Own General Contractor in California?
The CSLB owner-builder exemption lets you act as your own GC — but the rules matter. Here's exactly what you can and can't do.

Every year, thousands of California property owners ask the same question: Can I manage my own construction project without hiring a licensed general contractor?
Building in California as an owner-builder?
Wexmoor Circle finances owner-builder construction loans — no W-2, no licensed GC required.
The short answer is yes — with conditions. The California Contractors State License Board (CSLB) recognizes an owner-builder exemption that allows property owners to pull permits and oversee construction on their own property without holding a contractor's license.
But the exemption has teeth. Misuse it and you're exposed to liability, permit denial, and lender rejection. This guide breaks it down clearly.
What Is the Owner-Builder Exemption?
Under California Business and Professions Code, an owner-builder is any individual who owns the property on which they plan to construct, alter, repair, improve, or remodel a building or structure. As an owner-builder, you can perform work that would otherwise require a contractor's license — as long as you meet the CSLB's criteria.
The three qualifying paths are:
- You do the work yourself (or with your own wage employees) and the structure is not intended for sale
- You contract with properly licensed subcontractors (limited to one single-family structure, up to four per calendar year for resale)
- You contract with a licensed Class B general contractor to perform and subcontract all work (no limit on number of structures)
Key rule: If you hire unlicensed workers on your owner-builder project, you become their employer under California law — which triggers workers' comp, tax registration, and OSHA obligations.
The 4-Structure Limit and 1-Year Residency Rule
Two rules catch most owner-builders off guard:
The 4-Structure Limit
If you build using the owner-builder exemption and intend to sell, you're limited to four or fewer structures per calendar year unless you hire a licensed Class B GC. This prevents unlicensed "developers" from exploiting the exemption at scale.
The 1-Year Residency Rule
For the primary residence exemption (where you build it yourself), the project site must be your principal place of residence for at least 12 months before construction. After completion, California law restricts selling within one year of obtaining the final inspection or certificate of occupancy.
Translation: if you build it and flip it immediately, you've voided the exemption's protections.
What Responsibilities Do You Assume?
As an owner-builder, you step into every role a licensed GC would hold:
- Pulling all building permits (county or city)
- Ensuring all subcontractors are licensed and carry liability insurance
- Providing workers' compensation insurance for any workers on-site
- Complying with OSHA job site safety standards
- Managing mechanics lien exposure from unpaid subcontractors and suppliers
- Coordinating city/county inspections at each construction phase
⚠️ Liability warning: If a subcontractor is injured and they are unlicensed or uninsured, you may be personally liable. Your homeowner's insurance policy may not cover job site injuries — always verify before breaking ground.
Can You Get Financing as an Owner-Builder?
This is where most California owner-builders hit a wall. Traditional banks and conforming lenders typically require:
- A licensed Class B GC on the project
- W-2 income documentation
- Builder approval from their internal list
Wexmoor Circle's owner-builder construction loan program is structured differently. We start with the asset — not the borrower profile. If the property and project make sense, we structure the financing around your owner-builder setup, including professional engineer supervision in place of a licensed GC requirement.
Our program uses a one-time close construction-to-permanent loan — one closing, one rate lock, converts to a permanent mortgage when the build is complete. No requalification. No second closing.
CSLB Owner-Builder vs. Licensed Contractor: When to Hire One
| Situation | Owner-Builder OK? | Recommendation |
|---|---|---|
| Primary residence, doing work yourself | ✅ Yes | Pull your own permits, use licensed subs |
| Investment property, hiring all subs | ✅ Yes (≤4/yr) | Verify all sub licenses via CSLB |
| Commercial or multifamily project | ❌ No | Must use licensed contractor |
| Selling within 1 year of completion | ⚠️ Risk | Consult attorney before proceeding |
| Seeking construction financing | ✅ With right lender | Asset-first lender like Wexmoor |
Next Steps
If you're planning a custom home build, ADU, or teardown-rebuild in California as your own GC, the owner-builder path is legitimate — but it requires preparation. Understand your permit obligations, lock in licensed subs early, and work with a lender who understands the owner-builder structure.

Common Questions
Frequently Asked Questions
Yes, under the CSLB owner-builder exemption. You must own the property, perform work yourself or through licensed subcontractors, and the structure generally must not be sold within one year. See CSLB Owner-Builder Overview for the full statute.
Under the subcontractor path, you can build up to four structures per calendar year intended for resale. If you hire a licensed Class B GC to complete all work, there is no annual limit.
Yes, if you hire any workers on your project. As the project owner acting as GC, you're treated as an employer under California law. Workers' comp is required for direct employees, and you should verify all subcontractors carry their own coverage.
Most conventional lenders won't. Wexmoor Circle offers owner-builder construction loans using asset-first underwriting — the property value drives the decision, not your W-2 or licensed GC requirement.
You become their employer under California law. This triggers workers' comp obligations, IRS registration, and personal liability for job site injuries. Always verify license status at cslb.ca.gov before hiring any subcontractor.
