Financing a Utah ADU
Most ADUs are funded with home equity or cash. We do not originate loans — this page explains the patterns we see so you can talk to your lender with a clearer scope and budget.
Educational only — not a loan offer
Product availability and qualification depend on your credit, equity, occupancy, and the lender. Confirm details with a licensed mortgage professional.
Pair this guide with the Utah ADU cost guide and a scoped band from the cost estimator.

How options compare on paper
Funding path comparison · educational
| Factor | Speed | Paperwork | Best when… |
|---|---|---|---|
| HELOC / equity loan | Fast draw | Moderate | Equity strong; keep 1st mortgage |
| Cash-out refinance | Slower close | Full underwrite | Rate/term reset already useful |
| Renovation / construction | Draws by stage | Highest | Larger detached / after-improved value |
| Cash / partners | Immediate | Low lending | Simple timeline; clear scope still required |
Assumption · Qualitative comparison for planning conversations — lenders set actual terms.
Quick path chooser
If
You like your current rate and have equity
Then
Ask about HELOC or home-equity loan first
If
You were already refinancing the primary
Then
Model cash-out against HELOC total cost
If
Detached build needs staged draws
Then
Ask lenders about renovation / construction products
If
Lender won’t count projected rent yet
Then
Bring comps + legal pathway; underwrite conservatively
Rental income in underwriting
Long-term ADU rent can help carry a payment, but lenders vary on how much projected rent they count before the unit exists. Bring a city-legal pathway (internal vs detached), a ballpark from the estimator, and neighborhood comps — not short-term vacation projections if your city limits stays under 30 days for ADU use.
“Underwrite the payment you can carry without rent, then treat ADU income as upside — not the only pillar.”
