As housing costs continue to rise and sustainability becomes a priority, more homeowners are turning to Accessory Dwelling Units (ADUs) and home retrofits as smart investments. Whether you’re adding a rental unit, creating space for family, or upgrading your home for energy efficiency, one key question comes first: How do you finance it?
If this is your first time exploring these options at SKS Construction, this guide will walk you through the most effective, accessible, and cost-efficient financing solutions available today.
Why Financing ADUs and Retrofits Matters
ADUs and retrofits can significantly increase property value, generate rental income, and reduce long-term utility costs. However, upfront costs can range from:
- $50,000 to $300,000+ for ADUs
- $10,000 to $150,000+ for retrofits
Choosing the right financing option can make or break your project’s feasibility.
Top Financing Options for ADUs
1. Home Equity Loans (HEL)
A home equity loan allows you to borrow against the equity you’ve built in your home.
Pros:
- Fixed interest rates
- Predictable monthly payments
- Ideal for large, one-time expenses like ADU construction
Cons:
Best for:
- Homeowners with substantial equity who want stable payments
2. Home Equity Line of Credit (HELOC)
A HELOC works like a credit card, letting you draw funds as needed during construction.
Pros:
- Flexible borrowing
- Pay interest only on what you use
- Great for phased projects
Cons:
- Variable interest rates
- Risk of rising payments over time
Best for:
- Projects with uncertain or evolving costs
3. Cash-Out Refinance
This option replaces your current mortgage with a new, larger one, giving you cash for your ADU or retrofit.
Pros:
- Lower interest rates compared to personal loans
- Single monthly payment
Cons:

- Closing costs apply
Best for:
- Situations where mortgage rates are favorable
4. Construction Loans

- Long repayment terms
Cons:
- Tied to property taxes
