The short answer
ADU financing in Los Angeles is the first real hurdle, because an ADU is a $100,000 to $300,000 decision and almost nobody pays cash. The financing question is really two questions: what will a lender advance against a building that does not exist yet, and what will the finished unit rent for.

ADU financing in Los Angeles is the first real hurdle, because an ADU is a $100,000 to $300,000 decision and almost nobody pays cash. The financing question is really two questions: what will a lender advance against a building that does not exist yet, and what will the finished unit rent for. Below are the loan products that actually work for ADUs, and the LA rent bands we see clients underwrite against. We are builders, not lenders or advisors.
Loan products that work for ADUs
- Fannie Mae HomeStyle Renovation, lends against the after-completion value
- FHA 203(k), lower down payment, more paperwork and stricter draw inspections
- HELOC, fast and flexible if you already hold substantial equity
- Cash-out refinance, only attractive if your current rate is above the market rate
- Construction-to-permanent, one closing, common on larger ground-up builds
What lenders ask for
- A permitted drawing set or at least a complete design set
- A fixed-price contract from a licensed general contractor
- An as-completed appraisal that includes the projected ADU rent
- Proof of contractor licensing, bonding and general liability insurance
- A draw schedule tied to inspected construction milestones
Los Angeles rent bands, 2026

Common questions
Is there still a $40,000 ADU grant in California?
The CalHFA ADU Grant Program offered up to $40,000 toward predevelopment costs for eligible low and moderate income homeowners. Funding has been exhausted and reopened more than once. Check CalHFA directly for current status before you count on it.
Can I borrow against the ADU's future rent?
Some renovation loan products let the appraiser include projected ADU rental income in the as-completed value, which raises what you can borrow. Not every lender does this, so ask before you apply.
What does an ADU do to my property value?
In Los Angeles a permitted ADU typically adds value on the order of the income it generates capitalized at local rates. The unpermitted version usually adds far less and can complicate a sale.
Do I pay more property tax?
The ADU is assessed as new construction and added to your existing base. Your original house is not reassessed. The LA County Assessor can give you the figure for your specific parcel.
Do you offer financing?
No. We are a construction company, not a lender or a financial advisor. We provide the fixed-price contract and drawing set your lender will require, and we work with the draw schedule they set.
