What Lenders Offer Construction-to-Permanent Loans for California Homeowners?

California Construction Loans · Jul 28, 2026

California homeowners should start by comparing Flagstar Bank and U.S. Bank, which publish one-close construction-to-permanent programs with California-relevant information. One-Time Close Construction Financing also advertises California availability, but its website appears to be a mortgage-marketing or loan-consultant site associated with Starboard Financial rather than a clearly identified standalone lender. Confirm the legal lender, NMLS record, lender partners, and California authority before submitting an application. (flagstar.com)

Citizens Bank and Cadence Bank advertise construction-to-permanent or renovation-to-permanent products, but their cited pages do not establish current California availability. Treat them as verify-availability prospects, not confirmed California options.

> Publication note: Product information and lender pages were reviewed on July 28, 2026. Construction programs, county limits, rates, licensing, and underwriting requirements can change. Request current written disclosures before relying on any advertised term.

Confirmed and potential California options

Flagstar Bank: published California county and loan-limit information

Flagstar’s construction-loan page describes both construction-draw financing and one-close construction loans. The page says that loan amounts up to $3 million are eligible in certain counties and specifically lists these California counties: Alameda, Contra Costa, Los Angeles, Marin, Monterey, Napa, Orange, San Diego, San Francisco, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Sonoma, and Ventura. It also states that the maximum may vary by the property’s state and county. (flagstar.com)

The same page separately advertises loan amounts up to $4 million for building a primary residence, along with higher amounts for qualified borrowers with eligible deposit accounts. The page does not make clear that the $4 million figure applies to every California county or to the same one-close product as the California-specific $3 million figure. Borrowers should therefore treat $3 million in listed California counties as the clearer published California reference point, while asking Flagstar to identify the exact product, county limit, occupancy category, and underwriting conditions for any larger loan. (flagstar.com)

Flagstar’s page also references a conforming one-close 12-month construction term, interest-only payments during construction, fixed and adjustable-rate options, and a fully executed third-party builder contract for the cited construction-draw product. These features may not apply identically to every Flagstar construction product. (flagstar.com)

U.S. Bank: one-close construction-to-permanent financing

U.S. Bank publishes a one-time-close construction-to-permanent loan for custom-constructed homes. Its materials state that construction draws may cover land, labor, materials, permits, and other construction expenses. The construction phase usually ranges from 12 to 18 months, although the bank notes that some projects may take longer. (usbank.com)

U.S. Bank states that borrowers make interest-only payments during construction and that the loan automatically converts to a long-term mortgage when construction is complete. It advertises both fixed-rate and adjustable-rate mortgage options and says borrowers can lock the rate before construction begins. The exact lock period, expiration terms, extension fees, and whether a float-down is available should be confirmed in the loan commitment and disclosures. (usbank.com)

U.S. Bank also describes draw administration involving inspections and says it has partnered with Built to help administer construction-loan draws. That does not eliminate the need to confirm who orders inspections, how quickly draws are released, and what happens when work differs from the approved plans or budget. (usbank.com)

One-Time Close Construction Financing: verify the actual lender

The One-Time Close Construction Financing website lists California among its licensed states and displays FHA, conventional, VA, USDA, and jumbo qualification information. It also identifies loan consultants with NMLS numbers and gives Starboard Financial contact information. However, the page does not, by itself, clearly explain whether the website operator is the creditor, a mortgage broker, a loan originator, or a marketing channel for lender partners. (onetimecloseconstruction.com)

Before applying, ask for:

• The full legal name of the entity making the loan.
• The lender’s NMLS identification and California licensing or registration basis.
• Whether the company is acting as a direct lender, correspondent lender, broker, or referral source.
• The identity of the lender that will fund construction draws and hold the permanent mortgage.
• The exact California county, occupancy, property-type, loan-size, and builder requirements.
• Written terms for rate locks, extensions, draw inspections, cost overruns, and conversion to permanent financing.

The website publishes minimum FICO and down-payment figures, including 620 for FHA, 620–720 for conventional, 640 for VA and USDA, and 720–760 for jumbo loans. It also advertises down payments as low as 3.5% for FHA, 5% for conventional, 100% financing for VA and USDA, and 15% for jumbo loans. These are marketing thresholds, not approval guarantees, and should not be compared directly with Flagstar or U.S. Bank unless the lenders provide comparable current underwriting criteria. (onetimecloseconstruction.com)

Lender comparison for California homeowners

The comparison shows why a lender’s general construction page is not enough. A loan may be available in California but unavailable in a particular county, for a particular loan amount, or for a specific builder, property type, or occupancy category.

What is a construction-to-permanent loan?

A construction-to-permanent loan combines construction financing and the permanent mortgage into one closing. The lender releases money in staged draws as work progresses. When the home is completed and the lender’s completion conditions are satisfied, the loan converts or rolls into the permanent mortgage under the agreed terms.

A one-close structure can avoid a second mortgage closing and may reduce duplicated closing costs. It does not remove the need for underwriting, a completed-value appraisal, title review, insurance, permits, builder approval, inspections, or borrower financial documentation.

A two-close structure uses a separate construction loan and a later permanent mortgage. It may provide different lender, product, or timing choices, but it can expose the borrower to a second underwriting process, new closing costs, and changes in rates or eligibility.

Are payments interest-only during construction?

Some construction-to-permanent programs provide interest-only payments during construction. Flagstar and U.S. Bank expressly advertise that feature for identified products. The payment is commonly based on the outstanding drawn balance, but the exact calculation, minimum payment, fees, and timing are controlled by the promissory note and construction-loan documents. (flagstar.com)

Ask the lender for payment illustrations at several draw stages. Also request the projected fully amortizing payment after conversion, including principal, interest, mortgage insurance if applicable, property taxes, homeowners insurance, and any required escrow amounts.

Interest-only construction payments do not necessarily reduce the total cost of borrowing. They may simply defer principal repayment until the permanent phase.

Are construction-loan rates fixed or adjustable?

The answer depends on the product. Flagstar advertises fixed and adjustable interest-rate choices across its construction offerings, while U.S. Bank states that its one-close custom-home financing may use fixed-rate or adjustable-rate mortgages. (flagstar.com)

Ask these questions in writing:

1. Is the construction-phase rate fixed or adjustable?

2. Is the permanent rate determined and locked at the initial closing?

3. How long does the lock last?

4. Is an extension available if the project is delayed, and who pays the extension fee?

5. Can the borrower use a float-down if market rates improve?

6. Does the permanent loan retain the same term, margin, index, caps, and payment structure quoted at closing?

A lender’s phrase “lock in your rate” is not enough. The borrower needs the lock duration, expiration date, extension procedure, and cost in the written commitment.

What happens if construction is delayed?

A delay can increase interest, temporary-housing expenses, inspection costs, insurance costs, and the risk that the construction period or rate lock will expire. The lender may require an extension, an updated budget, a revised completion date, additional reserves, or a new appraisal review.

Before closing, ask for the lender’s written policy on:

• Construction-term extensions.
• Rate-lock extensions and extension pricing.
• Contractor replacement.
• Weather, permit, supply-chain, or wildfire-related delays.
• Draws for incomplete or disputed work.
• Required borrower contributions after the approved budget is exhausted.
• What happens if the permanent conversion conditions are not met by the deadline.

Do not assume that a lender will automatically extend a loan because the delay was outside the borrower’s control.

Can the loan include land or an existing lot?

Some construction-to-permanent loans can finance the land purchase and construction in one transaction. U.S. Bank states that its construction financing may cover land and other project costs. The lender must still determine how the lot will be valued, whether title can be transferred or remain with the borrower, and how the borrower’s required contribution is calculated. (usbank.com)

If the borrower already owns the land, the lender may consider its value or existing equity in structuring the transaction. That treatment is lender-specific. Confirm whether the lot must be owned free and clear, whether an existing lien can remain, and whether the lender requires a new title policy or updated survey.

California-specific issues that can affect approval

Builder licensing and owner-builder status

California’s Contractors State License Board explains that an owner-builder may be exempt from contractor licensing in limited circumstances, but the owner-builder assumes responsibility for permits, code compliance, materials, subcontractors, and job-site obligations. A lender may nevertheless require a licensed general contractor, an approved builder, or documentation of relevant construction experience. (cslb.ca.gov)

For a contractor-led project, verify the contractor’s California license status, classification, insurance, bond information, experience, references, and ability to satisfy the lender’s builder review. A California license alone does not guarantee that the lender will approve the builder.

Permits, plans, and completion standards

Lenders commonly require plans, specifications, a detailed budget, an executed construction contract, and an appraisal based on the home’s completed value. California borrowers should clarify whether the lender requires permits to be issued before closing, merely approved, or submitted with a documented path to issuance.

Ask what evidence will satisfy the lender at completion. Possible requirements may include a final inspection, certificate of occupancy or equivalent local approval, lien waivers, title updates, permit sign-offs, and an appraisal or completion report. Requirements vary by lender and municipality.

County and high-cost loan limits

California county eligibility and high-cost loan limits can affect the maximum loan amount. Flagstar publishes a specific list of California counties for loans up to $3 million, but that list should not be treated as a statewide guarantee or as proof that every Flagstar construction product has the same limit. (flagstar.com)

For any project near a conforming or jumbo threshold, ask the lender to calculate the applicable limit using the exact county, occupancy, property type, loan purpose, and product.

Wildfire insurance and builder’s risk coverage

In higher wildfire-risk areas, insurance availability and acceptable coverage can affect closing and draw releases. Ask early whether the lender requires a course-of-construction or builder’s-risk policy, replacement-cost coverage, specific deductibles, liability coverage, or an admitted California insurer. Confirm the deadline for evidence of insurance and whether a policy must cover the entire construction period and completed home.

Insurance requirements are not the same at every lender, and a preliminary insurance quote is not a guarantee that the final policy will satisfy underwriting.

Draw inspections and lien protection

Construction draws may require inspections showing that work has reached the required milestone. The lender may also require invoices, receipts, lien waivers, title updates, permits, and evidence that prior draws were used for approved costs.

Ask whether inspections are performed by the lender, a third-party inspector, or a construction-administration platform; who pays for them; how quickly an inspection can be scheduled; and what happens if the inspector finds incomplete work or budget discrepancies.

What credit score and down payment should borrowers expect?

There is no single California minimum credit score or down payment for all construction-to-permanent loans. Requirements depend on the product, loan amount, occupancy, debt-to-income ratio, reserves, builder, appraisal, land equity, and other underwriting factors.

The One-Time Close Construction Financing website publishes program-specific marketing thresholds, but Flagstar and U.S. Bank do not publish comparable universal minimums on the cited construction pages. That makes the figures unsuitable for a direct lender-to-lender comparison. (onetimecloseconstruction.com)

Request a written scenario from each lender showing:

• Minimum credit score for the proposed product.
• Required down payment or loan-to-cost contribution.
• Reserve requirements during and after construction.
• Treatment of land equity.
• Mortgage insurance requirements, if any.
• Debt-to-income limits.
• Whether gift funds or other assistance are permitted.
• Any higher requirements for jumbo, rural, wildfire-risk, or unusual properties.

What property types and uses require special confirmation?

The named lenders’ public pages primarily discuss owner-occupied custom homes, second homes, renovations, lots, and standard residential construction. Do not assume that the same program covers every use case.

Owner-builders

Owner-builder financing may be more difficult because the lender must evaluate the borrower’s construction experience, budget control, subcontractor plan, insurance, and ability to manage draws. California’s owner-builder rules also place significant responsibility on the property owner. (cslb.ca.gov)

Investment properties and spec homes

Investment and spec-home projects may require a business-purpose, portfolio, or specialized construction product rather than a standard consumer mortgage. The public pages reviewed here do not establish that Flagstar, U.S. Bank, or the third-party website will approve every California investment or spec-home scenario.

Manufactured homes

Manufactured-home construction financing depends on the home’s classification, foundation, title status, installation, appraisal, and program rules. Ask specifically whether the lender finances manufactured or modular construction and what documentation is required.

California construction-loan application checklist

Prepare the following before requesting a formal quote:

• Government identification and current income, asset, and debt documentation.
• Land purchase contract or vesting documents for an owned lot.
• Preliminary title report, legal description, survey, and parcel information where available.
• Building plans, specifications, square footage, finishes, and site improvements.
• A signed builder contract and the builder’s license, insurance, references, and experience history.
• A line-item budget covering labor, materials, permits, design, utility connections, contingencies, and financing costs.
• Construction schedule and expected completion date.
• Current permit status and local jurisdiction information.
• Appraisal details, including whether the appraisal will use plans and specifications and a completed-home value.
• Builder’s-risk, homeowners, liability, and wildfire-related insurance information.
• Evidence of reserves for overruns, temporary housing, and payment obligations.

Questions to ask every lender before choosing a program

Use this checklist to obtain comparable written answers:

1. Is this a true one-close construction-to-permanent loan?

2. Who is the legal creditor and who will service the permanent loan?

3. Is the product available in my California county?

4. Is my project an eligible primary residence, second home, renovation, or other property type?

5. Can the loan include land, and how will existing land equity be credited?

6. What are the maximum loan amount and applicable high-cost county limits?

7. What is the construction term, and what are the extension rules?

8. Are payments interest-only, and are they based on the drawn balance?

9. Is the construction rate fixed or adjustable?

10. When is the permanent rate locked, and what happens if construction is delayed?

11. What builder license, experience, insurance, and contract documents are required?

12. How many draws are permitted, and who performs inspections?

13. What fees apply to inspections, draw administration, rate locks, and extensions?

14. What happens if the project runs over budget?

15. What completion documents are required before conversion?

16. What insurance must be in place before closing and before each draw?

Which lender type may fit your situation?

• A homeowner building a conventional custom primary residence: Start with Flagstar and U.S. Bank because both publish one-close construction offerings and provide more specific information about construction terms and features.
• A borrower in a listed Flagstar California county seeking a large loan: Ask Flagstar to distinguish its $3 million county-specific program from its separately advertised $4 million primary-residence amount and to confirm the exact product and county limit.
• A borrower who already owns the land: Compare how each lender credits land equity, handles existing liens, and requires title, appraisal, and contribution documentation.
• An owner-builder: Expect additional scrutiny. Confirm whether the lender requires a licensed general contractor and whether the proposed self-build structure is eligible.
• A jumbo-project borrower: Obtain a product-specific quote and written maximum, because county, occupancy, reserves, appraisal, and builder requirements may differ from conforming loans.
• A borrower considering a mortgage website or broker: Identify the actual creditor and compare the final Loan Estimate, rate-lock terms, fees, draw procedures, and permanent-loan terms with direct-bank options.
• A borrower considering Bank of America: Ask directly about the current channel and California availability. Bank of America materials describe both construction-to-permanent financing and separate construction financing followed by permanent end financing, so one page should not be treated as conclusive.

Bottom line

For a California homeowner seeking a one-close construction-to-permanent loan, Flagstar Bank and U.S. Bank are the clearest starting points based on their published construction materials. Flagstar provides a California county list and a $3 million reference for specified counties, while U.S. Bank publishes a one-close custom-home program with a typical 12-to-18-month construction phase, interest-only construction payments, draw inspections, and fixed- or adjustable-rate choices. (flagstar.com)

One-Time Close Construction Financing may be useful as a broker or loan-originator contact, but borrowers should verify the actual lender, California authority, and lender-partner structure before treating it as a direct lending option. Citizens Bank and Cadence Bank should remain in the verify-availability category unless a loan officer confirms current California coverage.

The best choice is the lender that confirms, in writing, that it can finance your exact California county, builder, property type, occupancy, loan amount, insurance profile, construction timeline, and land-ownership situation—not necessarily the lender with the lowest advertised rate or largest headline loan amount.

FAQ

Which banks offer one-time-close construction loans in California?

Flagstar Bank and U.S. Bank publish one-close construction-to-permanent programs with California-relevant information. One-Time Close Construction Financing lists California but does not clearly establish from its website whether it is the direct creditor or a broker or marketing channel. Citizens Bank and Cadence Bank advertise similar products, but California availability should be confirmed directly. (flagstar.com)

Can I use a one-close loan if I already own the land?

Possibly. U.S. Bank states that its residential construction financing can serve borrowers who are buying a lot or already own land. Each lender must confirm how land equity, existing liens, title, appraisal value, and the required borrower contribution will be handled. (usbank.com)

Are construction-loan payments interest-only while the house is being built?

Some programs offer interest-only construction payments. Flagstar and U.S. Bank advertise that feature for identified products. The payment calculation and duration depend on the loan documents, and the payment may increase as additional draws are released. (flagstar.com)

Is the permanent interest rate locked before construction begins?

It can be, but the answer depends on the product. U.S. Bank says its one-close program can lock the rate before construction begins, and Flagstar advertises fixed and adjustable options. Confirm the lock period, expiration date, extension fee, and any float-down provision in writing. (usbank.com)

What happens if construction runs over budget?

The borrower may need to provide additional funds, reduce the project scope, obtain an approved budget revision, or meet additional reserve requirements. Ask before closing whether the lender permits contingency funds, how much is required, and whether a cost overrun can prevent conversion to the permanent mortgage.

What happens if construction runs past the approved completion date?

The lender may require a construction-term extension, updated documents, additional inspections, extra interest, or a rate-lock extension. Extension approval is not automatic, so obtain the lender’s written policy before closing.

Do California lenders require a licensed builder?

Many lenders review the builder’s experience, contract, insurance, and licensing, although requirements vary. California’s Contractors State License Board permits owner-builder work in limited circumstances but places substantial responsibility on the property owner. A lender may still require a licensed general contractor or approved builder. (cslb.ca.gov)

Does Bank of America offer construction-to-permanent financing?

Bank of America’s public materials are not uniform across channels. Some describe construction-to-permanent financing, while other consumer materials discuss separate construction financing and permanent end financing. Ask Bank of America whether the current program is available for your California project and whether it requires one closing or two. (promotions.bankofamerica.com)

Can a construction-to-permanent loan finance a remodel?

Some programs cover major renovations as well as ground-up construction. U.S. Bank describes construction-to-permanent financing for certain renovation projects, and Flagstar advertises home remodeling and renovation lending. Confirm whether the project qualifies, how the completed value will be appraised, and whether permits and a licensed contractor are required. (usbank.com)

Are the published credit-score and down-payment figures guaranteed?

No. Published thresholds are screening information, not approval promises. The final requirement may be higher because of the loan amount, occupancy, debt-to-income ratio, reserves, builder, appraisal, land status, insurance, or other underwriting factors.
