For many Sonoma County households, the home is one of the largest assets. Under California law as of October 2026, Proposition 19 may allow homeowners age 55 or older to transfer the taxable value of their primary residence to a replacement primary residence anywhere in California, up to three times. If the replacement home's market value is above a threshold that depends on when it is bought relative to the sale, the difference is added to the transferred value. Proposition 19 also narrowed the property tax break for homes passed to children or grandchildren: it generally applies now only if the heir uses the home as a primary residence, and only up to a value limit. Whether you downsize, stay put, or plan to leave the home to family can affect cash flow, taxes, and what your heirs receive.
