In California, you generally need to be 18 years old to independently buy a house and sign a binding real estate purchase contract. A minor can legally own real estate, such as through a gift or inheritance, but California Family Code § 6701 prevents minors from making contracts relating to real property. An adult does not necessarily have to be added to the deed, but a parent, guardian, trustee, or other legally authorized adult may need to handle the transaction or manage the property. In practice, buying a home before 18 can be complicated, especially if financing is involved, so it's worth consulting a California real estate attorney about the ownership structure.
