California Proposition 19: Parent-Child Real-Property Transfers After 2021

For decades, California families could pass their California real property — a primary residence, a vacation home, an investment property — from parent to child without triggering a reassessment of the property to current market value for property-tax purposes. The mechanism was the parent-child exclusion to Proposition 13 reassessment, established by Proposition 58 (1986) and expanded by Proposition 193 (1996) for grandparent-grandchild transfers.

In November 2020, California voters passed Proposition 19, which substantially narrowed those exclusions. The new rules took effect on February 16, 2021, and have now been in operation for several years. This post is a plain-English overview of what the rule now is, how it has changed estate-planning analysis, and what families with California real property should be thinking about.

What changed

Before Proposition 19, the parent-child exclusion worked like this:

• A parent could transfer their primary residence to a child without reassessment, regardless of value or what the child did with the property
• A parent could also transfer other real property (rentals, vacation homes, vacant land) up to a $1,000,000 assessed-value limit per parent ($2,000,000 for a couple) without reassessment
• The child inherited the parent's base year value under Proposition 13, often producing dramatically lower property taxes than current market value would imply

Proposition 19 narrowed both pieces:

1. Primary-residence exclusion is now conditional. A parent can still transfer the primary residence to a child without reassessment, but only if the child uses the property as the child's own primary residence within one year of transfer. If the child does not move in, the property is reassessed to current market value (with a partial exclusion in some cases — see below).

2. The non-residence exclusion is gone. Other real property — investment properties, vacation homes, second homes — no longer qualifies for any parent-child exclusion. These properties are reassessed to current market value upon transfer.

3. There is now a value cap on the residence exclusion. Even where the child does move into the inherited primary residence, the exclusion only applies up to a defined dollar threshold. The threshold equals the assessed value at transfer plus $1,000,000 (the latter figure indexed for inflation). Any value above that threshold is reassessed proportionally.

What this means in practice

Before Proposition 19:

• A parent's $2 million Beverly Hills home, with a Proposition 13 base of $400,000 (because the parent bought it in 1985), could pass to the child with the same $400,000 base. The child's property tax stayed at roughly the same level the parent had been paying — $4,000 to $5,000 per year — even though the property was worth $2 million.
• A parent's portfolio of three rental houses in San Diego, with assessed values totaling $1 million but market values totaling $4 million, could pass with the assessed-value bases intact. The child inherited substantially below-market property tax bases on the rentals.

After Proposition 19:

• The Beverly Hills home only keeps the $400,000 base year value if the child moves in. If the child moves in but the home is now worth $2 million and the inflation-indexed exclusion is roughly $1.4 million ($400,000 base + $1M indexed), the new base year value would be approximately $600,000 (the $2 million current value minus the $1.4 million exclusion). Property taxes go up correspondingly.
• The three rental houses are reassessed to current market values. The child inherits approximately $4 million in assessed value rather than $1 million — and pays property tax on that.

For California families who built wealth through real estate held for decades, the property-tax consequences of Proposition 19 can be substantial. Properties that were reasonable to hold across generations under the prior framework can become uneconomic to retain under the new rules.

What this changes about estate planning

Proposition 19 has shifted estate-planning analysis for California real estate in several ways:

1. Lifetime planning matters more. Some families have shifted to lifetime gifting strategies — transferring real property to children during the parents' lives — to lock in property-tax bases under specific scenarios. These strategies have their own tradeoffs (loss of step-up in income-tax basis at death, gift-tax considerations, control implications) but produce a different property-tax outcome than waiting for inheritance.

2. Trust structures have to account for occupancy. A trust that distributes a primary residence to a child needs to consider whether the child will occupy it. Where the child will not occupy, the family may want to consider a sale during life, a different distribution structure, or simply accepting the property-tax reassessment as the cost of the transfer.

3. Investment-property planning has changed. Without the prior $1 million-per-parent exclusion for non-residence property, families with significant rental portfolios face property-tax reassessment on inheritance. Some families have explored entity-based ownership structures (LLCs, family limited partnerships) that can affect the property-tax analysis under specific narrow rules — though the rules around entity transfers are themselves complex and must be designed carefully.

4. The parent-grandchild path remains, with limits. Where a child predeceases a parent, the parent's transfer to a grandchild can still qualify for the exclusion, subject to the same primary-residence and value-cap rules. This narrow path can sometimes be useful in family-planning situations.

What this does NOT change

Several things commonly confused with Proposition 19 are not affected by it:

• Federal income-tax basis. Proposition 19 is a property-tax rule. The federal income-tax step-up in basis at death under IRC § 1014 is unchanged. A child inheriting California real property still receives a step-up in basis to fair market value at death for federal income-tax purposes, regardless of what happens to the property-tax base year value.
• Probate avoidance. A funded revocable living trust still avoids California probate for the property held in the trust, regardless of the property-tax consequences.
• Spousal transfers. Transfers between spouses are not affected; they remain excluded from reassessment under separate rules.

Practical takeaway

For families with significant California real estate, a careful Proposition 19 analysis is now part of the estate-planning conversation. The conversation often involves:

• A property-by-property review of current assessed value, current market value, and likely intended use post-inheritance
• An analysis of whether the child or children will occupy any of the residences
• Consideration of lifetime-transfer alternatives where the property-tax stakes are particularly high
• Coordination with the broader tax picture (federal estate tax, federal income-tax basis, gift-tax rules)

The right answer is family-specific. Some families decide that the property-tax reassessment is a cost of doing business and continue to plan around it; others restructure significantly to preserve property-tax efficiency. The choice depends on the specific properties, the specific family, and the specific goals.
