To finance an ADU, homeowners can explore several options:
Home Equity Loans and HELOCs: Borrow against your home’s equity. Home equity loans provide a lump sum, while HELOCs offer a flexible line of credit.
Cash-Out Refinancing: Replace your existing mortgage with a larger one, using the difference to fund the ADU.
Construction Loans: Specifically for building projects, these loans convert to a regular mortgage upon completion.
Government Programs: Look for local grants and loans, like California’s CalHFA ADU Grant Program, which offers up to $40,000 for ADU development.
