Construction and Renovation Financing in California: 203k, HomeStyle, ADU Loans, and More

Construction financing in California is one of the most misunderstood areas of real estate. Most buyers assume you need the full purchase price plus construction budget in cash to do any significant work on a property. The reality is more useful than that.

Construction-to-Permanent Loans (One-Time Close)

A construction-to-permanent loan, also called a one-time close or OTC loan, finances both the construction phase and the long-term mortgage in a single loan. You close once, draw funds as construction progresses, and then the loan converts to a standard mortgage when the project is complete.

This structure eliminates the risk and cost of a second closing and locks in your permanent rate at origination. For buyers purchasing a lot and building from scratch, or for major gut rehabilitations, this is often the cleanest financing path.

FHA 203(k) — Renovation Financing

The FHA 203(k) program allows buyers to finance both the purchase of a home and the cost of repairs or renovations into a single FHA loan. There are two variants:

Limited 203(k): For projects up to $35,000, covering cosmetic repairs and improvements that do not involve structural work.

Standard 203(k): For larger projects including structural rehabilitation, additions, and significant systems work. Requires a HUD-approved consultant.

The 203(k) is particularly powerful in Los Angeles, where buyers are often competing on properties that need work. A buyer who can close on a distressed property and fold renovation costs into their mortgage has a fundamentally different bidding position than an all-cash buyer trying to squeeze a deal.

Fannie Mae HomeStyle Renovation Loan

The conventional equivalent of the 203(k), the HomeStyle loan allows renovation financing up to 75% of the property's completed appraised value. It is available for primary residences, second homes, and investment properties — a significant advantage over the FHA product, which is limited to primary residences only.

ADU Construction Financing

California's ADU-friendly regulatory environment has generated a parallel financing market. Several lenders now offer ADU-specific products, including:

• Cash-out refinance: Pull equity from the primary property to fund ADU construction.
• Home equity line of credit (HELOC): Draw on available equity as needed during construction.
• RenoFi loans: A newer product that allows homeowners to borrow against the after-renovation value of their home, rather than current equity — significantly increasing borrowing capacity.
• CalHFA ADU Grant: CalHFA has offered grant programs to help low-to-moderate income homeowners cover pre-development ADU costs. Check current availability.

Hard Money and Bridge Financing

For investors and developers who need to move quickly or who do not qualify for conventional financing, private/hard money lenders remain an active part of the Los Angeles market. These are short-term loans at higher rates, used to acquire, rehabilitate, and either sell or refinance into permanent financing. The math works when the deal is right; it does not work when acquisition or construction costs are miscalculated.

SBA 504 for Mixed-Use and Commercial

For buyers of mixed-use properties with a commercial component, the SBA 504 loan program provides long-term, fixed-rate financing for commercial real estate acquisition and improvement. The structure typically involves a conventional first lender at 50%, a Certified Development Company at 40%, and a 10% down payment — making it accessible for owner-occupied commercial properties.

Key Questions to Ask Any Lender

Before committing to any construction or renovation financing, get answers to: What is the draw schedule and who controls it? How is the property appraised — as-is or after completion? What happens if construction costs exceed estimates? What are the prepayment penalties? Is there a rate lock, and for how long?
