Does My Child Have to Live in the Inherited House to Keep My Low Property Taxes?

Yes. Under Proposition 19, a child keeps a parent’s low property tax base on the family home only if they move in and make it their own principal residence within one year of the transfer. There is no version of this where the child inherits the house, keeps it, rents it out or leaves it empty, and still keeps the low tax bill. The move-in is the condition.

This is the question California families ask most often, and the answer surprises nearly everyone who remembers the old rules.

What Changed, and Why Families Are Caught Off Guard

For 35 years, the answer to this question was no.

Under Proposition 58, a parent could transfer their home to a child and the child kept the low tax base regardless of where they lived. They could rent it out, leave it empty, or use it as a vacation place. The benefit followed the property, not the person.

Proposition 19 reversed that. For transfers on or after February 16, 2021, the exclusion follows a child who actually lives in the home.

The reason this catches families is that the change was not widely understood, and estate plans written before 2021 assumed the old rule. Parents told their children the house would pass with its low taxes. That was true when they said it. It stopped being true, and nobody sent a notice.

What “Live In It” Actually Means

The standard is principal residence, the home the person actually lives in as their main home. It is not a technicality you satisfy on paper.

What satisfies it: the child moves in and makes the home where they actually live, then files for the homeowners’ exemption. That exemption filing is the mechanism. It is a small property tax reduction available to owners who occupy their own home, and it is what tells the assessor this is a principal residence rather than an investment.

What does not satisfy it:

• Renting the home to tenants, even at below-market rent to a family member
• Leaving the home vacant while deciding what to do
• Using it as a second home or weekend place
• Holding it through an LLC, which cannot claim the homeowners’ exemption at all
• Intending to move in eventually, past the one-year mark

There is a second condition on the parent’s side that people forget. The home must have been the parent’s principal residence too. A house the parent owned but rented out is not a family home under this rule, no matter who inherits it or who moves in afterward.

The One-Year Clock, and Why It Runs Out

The child has one year from the date of transfer to occupy the home and claim the exemption. For an inheritance, that date is generally the date of death, not the date probate closed, not the date the deed was recorded, not the date the estate was distributed.

That distinction matters more than it sounds. Probate routinely takes longer than a year in California. A family that waits for the estate to settle before anyone moves in has often already lost the benefit.

The deadline is strict. There is no grace period and no extension. Once the year passes without the move-in and the filing, the home is reassessed to market value, and the benefit for the period before you finally file is gone permanently.

And no one warns you. Assessors do not send reminders. Families discover the loss when a corrected tax bill arrives.

What It Costs to Get This Wrong

Numbers make the stakes concrete.

A Sacramento parent’s home has a Proposition 13 assessed value of $230,000 and a market value at death of $900,000. At the basic one percent rate the parent was paying roughly $2,300 a year.

If the child moves in within the year and claims the exemption, the assessed value stays near $230,000. The annual bill stays near $2,300.

If the child does not, the home is reassessed to $900,000. The annual bill becomes roughly $9,000.

That is a difference of $6,700 every year, indefinitely, decided entirely by whether someone moved into the house and filed a form.

Over a decade of ownership, the gap is roughly $67,000. It is usually the largest financial consequence of any decision the family makes in that first year.

What If Several Children Inherit?

Then the answer becomes partial, and the structure of ownership matters.

If the siblings all take title and hold the home as co-owners, only the sibling who makes it their principal residence keeps the low base, and only on their share. The shares belonging to siblings who live elsewhere are reassessed to market value. The family keeps part of the benefit rather than all of it.

The outcome changes if the home ends up owned entirely by the child who lives there, for example, because the estate distributes the whole home to that child rather than splitting it among all of them. Then the full home can qualify, because the resident owns all of it.

This is worth arranging deliberately, and it is easier to arrange while the parent is alive. A related trap: if the siblings first inherit as co-owners and one later buys the others out, that buyout is a sibling-to-sibling sale, which gets no exclusion and reassesses the purchased shares. Handling the buyout during trust or estate administration, before distribution, avoids that result.

Even Moving In Does Not Fully Protect a Valuable Home

One more limit worth knowing. Satisfying the move-in condition does not shelter unlimited value.

Proposition 19 caps the benefit at the home’s factored base year value plus an inflation-adjusted amount, $1,044,586 for transfers from February 16, 2025 through February 15, 2027. If the home’s market value at transfer exceeds that ceiling, the excess is added to the low base as a partial reassessment.

For a home worth less than the ceiling, moving in preserves the base entirely. For a very valuable home, moving in still saves a great deal, just not everything.

The Conversation to Have Now

Because the exclusion turns entirely on one fact, every family plan should start with an honest answer to one question: will a child actually make this home their main residence within a year?

Ask each child directly, and treat it as a practical question rather than a sentimental one. Their job, their own home, their family, and their willingness all matter. If one child genuinely will move in, the plan can direct the home to that child and make sure they know the clock starts at the date of death. If no child will, the low base will not survive, and the family can decide what to do about that in advance rather than discovering it too late.

Avoiding this conversation is the most common planning failure there is. Families assume a child will keep the home and its low tax bill, never confirm that the child can or will live there, and lose the exclusion by default.

Summary

• Yes, the child must live in the inherited home as their principal residence to keep the low tax base.
• They have one year from the date of transfer, generally the date of death, and must also claim the homeowners’ exemption.
• Renting it out, leaving it vacant, or holding it in an LLC all fail the test.
• The home must also have been the parent’s principal residence.
• Before February 16, 2021, no occupancy was required, which is why so many families are surprised.
• When several children inherit as co-owners, only the resident child’s share keeps the low base.
• Even a qualifying home is capped at the base year value plus $1,044,586 through February 15, 2027.
