Owner Builder Construction Loans in California
If you plan to manage your own home build in California, your financing needs to match that approach. Owner Builder Loans AZ, LLC is a private lender offering short-term construction loans for owner-builders in California. We do not offer single-close or construction-to-permanent loans.
Our program is for a new single-family home intended as your primary residence. Contact our team to confirm that your project fits before you spend time preparing a loan package.
How the construction loan works
OBL’s construction loan has a 12-month term. Funds are advanced through construction draws, and interest is paid on the amounts advanced. The construction rate is fixed during the loan period and depends on the qualifying credit score.
After the build, you arrange a separate refinance to repay the construction loan. Permanent financing has its own approval process and terms. There is no automatic conversion or promise of a long-term rate locked at the construction closing.
Review the credit and equity guidelines
Our qualification guidelines use the following credit tiers. The equity percentage is applied to the construction loan amount, not to total project cost. These are program limits, subject to the full loan review and any changes to requirements.
| Qualifying credit score | Minimum equity | Maximum loan amount |
| 700 to 724 | 50% of loan amount | $450,000 |
| 725 to 749 | 45% of loan amount | $500,000 |
| 750 to 774 | 40% of loan amount | $550,000 |
| 775 to 799 | 35% of loan amount | $700,000 |
| 800 and above | 30% of loan amount | $700,000 |
Across these tiers, the maximum debt-to-income ratio is 38% and maximum loan-to-value ratio is 70%. The qualifying credit score is the middle score from a tri-merge report. For two borrowers, OBL uses the lower of the two middle scores.
Equity considers land value less land debt, plus qualifying project costs you have paid. OBL will confirm what counts and when the required equity must be in place. Final land value depends on the appraisal.
Understand the income and appraisal tests
Debt-to-income compares qualifying monthly debt payments, including the future refinance payment, with gross monthly income. It is not calculated as 38% of your loan amount. OBL reviews the debts and income that apply to your situation.
The LTV limit compares the construction loan with the finished home’s appraised value. It is a separate test from the equity requirement. A strong credit score or substantial land equity does not remove the need for an acceptable appraisal and complete project review.
Check California permit responsibilities early
California’s Contractors State License Board explains that an owner-builder is responsible for permits, code compliance, inspections, and managing the project. Before choosing this route, review the CSLB’s owner-builder guidance and contact the building department responsible for your property.
Ask which plans, permits, trade licenses, and site approvals your project needs. Have your design professionals confirm the applicable energy, structural, and site requirements. This article does not replace a review of the rules for your parcel.
OBL does not require you to hire a general contractor, but that lending policy does not waive state or local requirements. The building permit must be issued before your construction loan closes.
Use the actual OBL draw process
OBL offers unlimited construction draws subject to the loan and budget conditions. Upfront releases may be available to pay for work and materials. Work with our team to plan requests around your approved budget and construction needs.
OBL’s loan inspections and the building department’s inspections serve different purposes. Coordinate required building inspections with the local authority, and ask OBL how it will review progress for your loan.
Common California financing questions
Can I start with a questionnaire
Yes. The Qualification Questionnaire is an initial information step, not a loan application or credit check. OBL can use it to prepare an evaluation of your project.
Can OBL consider a project already under construction
Yes, subject to review. Provide details about completed work, money already spent, and the remaining budget.
Is an extension guaranteed
No. Extensions may be available. Contact OBL early to discuss the terms if your build or refinance schedule changes.
