For decades, California families could pass real property to their children without triggering a property tax reassessment. A parent who bought a home in Montecito in 1978 for $400,000, now worth $8 million, could leave that property to a child and the child would continue paying taxes on the 1978 assessed value. That era ended on February 16, 2021, when Proposition 19 took effect.
The change was significant. It was also widely misunderstood, and the misunderstanding is still costing California families money. If you have inherited property, expect to inherit property, or are making decisions about a California estate, understanding what Prop 19 actually changed and what it did not is essential before any real estate decision is made.
What Prop 19 actually changed
Before Prop 19, the parent-child exclusion from property tax reassessment applied broadly. A child could inherit a parent’s primary residence, vacation home, investment property, or rental and keep the parent’s low assessed value, regardless of how the child intended to use the property. There was no cap on the assessed value that could be transferred.
Prop 19 narrowed that exclusion significantly. Under current law, the parent-child exclusion applies only when the child uses the inherited property as their primary residence, and only within one year of the transfer. Even then, the exclusion is capped: the child’s assessed value is only protected up to $1 million above the parent’s assessed value. Any value above that threshold is reassessed at current market value.
For a property worth $8 million with a parent’s assessed value of $500,000, the math works like this. The child establishes primary residence within one year. The exclusion protects up to $1.5 million in assessed value ($500,000 base plus the $1 million cap). The remaining $6.5 million is reassessed at current market value. At California’s 1% base tax rate, that difference translates to roughly $65,000 in additional annual property tax.
If the child does not use the property as a primary residence, the exclusion does not apply at all. The property reassesses to full current market value at the time of transfer.
What this means for Montecito estates
Montecito creates a specific challenge. Many properties in 93108 are second homes or vacation residences for families whose primary lives are in Los Angeles, San Francisco, or New York. For those families, Prop 19’s primary residence requirement means the parent-child exclusion does not apply, regardless of trust structure or estate planning. The property reassesses to current market value at the time of transfer, and the beneficiaries inherit both the asset and a property tax bill that may be ten to twenty times what the prior generation paid.
For families where the Montecito property is the primary residence, and where a child intends to make it their own primary residence, the exclusion still applies with the $1 million cap. That is meaningful protection, though not complete. At current Montecito valuations, most estates will still see some reassessment even when the exclusion is available.
The trust structure does not, by itself, determine whether the exclusion applies. A property held in a revocable living trust passes to beneficiaries as a parent-child transfer for Prop 19 purposes. What matters is how the child uses the property after the transfer, not how the property was held before it.
The timing and structure question
The real estate dimension of Prop 19 is where many families make decisions without full information. The choice between selling a property before a parent’s death, transferring it through a trust, or holding it as an investment after inheritance all carry different property tax consequences, different capital gains implications, and different real estate outcomes.
A sale during the parent’s lifetime allows the family to capture the current market value and may eliminate capital gains tax on appreciation that occurred during the parent’s lifetime. A transfer at death may or may not qualify for the parent-child exclusion depending on the child’s intentions. An inherited property held as a rental will be reassessed to current market value and may also generate rental income that creates additional tax complexity.
These decisions cannot be made by a real estate advisor alone. They require coordination between an estate attorney, a CPA, and an advisor who understands the real estate dimension of the choice. What the real estate advisor brings to that table is knowledge of current market conditions, an honest assessment of what the property would sell for today, and the ability to structure a sale or listing process that produces the best outcome for the family within whatever constraints the legal and tax analysis establishes.
Frequently Asked Questions
What did Prop 19 change about inheriting property in California?
Prop 19, which took effect February 16, 2021, eliminated the broad parent-child exclusion from property tax reassessment. Under previous law, children could inherit any type of property and keep the parent’s assessed value. Under Prop 19, the exclusion applies only when the child uses the property as their primary residence within one year of the transfer, and only up to $1 million above the parent’s assessed value. Properties that do not qualify are reassessed to current market value at the time of transfer.
Does a trust protect inherited property from Prop 19 reassessment?
No. Trust structure does not determine whether the Prop 19 exclusion applies. A property held in a revocable living trust passes as a parent-child transfer for Prop 19 purposes, but what governs the exclusion is whether the child uses the property as a primary residence after the transfer, not how it was held before. An estate attorney should be consulted on the specific trust provisions.
How does Prop 19 affect a Montecito vacation home or second home?
If the property is a second home or vacation residence and the child does not intend to use it as a primary residence, the parent-child exclusion does not apply. The property will reassess to full current market value at the time of transfer. At Montecito valuations, this can represent a significant increase in annual property tax. Families in this situation should evaluate whether a sale during the parent’s lifetime may produce a better overall outcome than a transfer at death.
What is the one-year requirement under Prop 19?
To qualify for the parent-child exclusion, the child must establish the inherited property as their primary residence within one year of the transfer. If the child fails to meet this deadline, the exclusion does not apply and the property is reassessed at current market value. The specific timing rules depend on the structure of the transfer and should be confirmed with an estate attorney.
Should I sell my Montecito estate before or after my death given Prop 19?
This depends on multiple factors: the property’s current assessed value versus market value, whether a child intends to use it as a primary residence, the capital gains implications of a sale versus a transfer, and the family’s broader estate plan. These decisions should involve an estate attorney, a CPA, and a real estate advisor who understands the current market before any action is taken.
