California Proposition 19, approved by voters in November 2020 and effective February 16, 2021, changed two major property tax rules. First, Prop 19 narrowed the parent-child and grandparent-grandchild reassessment exclusion. The exclusion now applies only to a primary residence (and certain family farms), only when the child or grandchild makes the property their own primary residence within one year, and only up to a capped value (the parent’s assessed value plus $1 million). Second, Prop 19 expanded base year value transfers for homeowners age 55 and older, severely disabled persons, and victims of wildfires or natural disasters. Eligible homeowners can now transfer their existing property tax assessed value to a replacement home anywhere in California up to three times, even if the replacement is more expensive. Prop 19 is codified in California Revenue and Taxation Code Sections 63.2 and 69.6.
Prop 19 is one of the most significant changes to California property tax law in 35 years. Allenby Law helps San Diego homeowners structure transfers, inheritances, and base year moves to preserve as much tax base as the law allows. Schedule a consultation.
What Is California Proposition 19?
Proposition 19 is the constitutional amendment passed by California voters on November 3, 2020, with 51.1 percent approval. It took effect in two stages. The new base year value transfer rules for seniors and disaster victims became effective April 1, 2021. The new parent-child and grandparent-grandchild exclusion rules became effective February 16, 2021.
Prop 19 replaced two earlier propositions:
Proposition 58 (1986): The original parent-child exclusion. Allowed parents to transfer a primary residence of any value, plus up to $1 million of assessed value in other real estate per parent, to children without triggering reassessment.
Proposition 193 (1996): The grandparent-grandchild exclusion. Allowed grandparents to make similar transfers to grandchildren when both of the grandchild’s parents were deceased.
Proposition 60 and 90 (1986/1988): The base year value transfer rules for homeowners 55 and older. Allowed a one-time transfer of assessed value to a replacement home of equal or lesser value, within the same county (Prop 60) or in certain participating counties (Prop 90).
Prop 19 substantially narrowed the parent-child rules and substantially expanded the senior transfer rules.
How Did Prop 19 Change the Parent-Child Exclusion?
Before Prop 19, a parent could transfer the following to a child without triggering property tax reassessment:
The parent’s primary residence, of any value, regardless of how the child used it after the transfer.
Up to $1 million of assessed value (per parent) in other real estate. For couples, this could mean up to $2 million in combined exclusions.
The child took the property at the parent’s existing Prop 13 base year value, often dramatically below current market value.
After Prop 19, the exclusion is much narrower:
The transferred property must be the parent’s primary residence at the time of transfer (or a family farm).
The child must establish the transferred property as their own primary residence within one year, file a Homeowners’ Exemption (BOE-266), and file a Claim for Reassessment Exclusion (BOE-19-P).
Even when both conditions are met, the protected assessed value is capped. The child’s new assessed value cannot be less than the fair market value at transfer minus $1 million.
Properties other than the parent’s primary residence (rentals, vacation homes, second homes, investment properties) are no longer eligible for the exclusion. They are fully reassessed at fair market value at the date of transfer.
What Is the New $1 Million Cap and How Is It Calculated?
The cap is the trickiest part of Prop 19. Here is how the math works.
When a qualifying parent-child transfer of a primary residence happens, the child’s new assessed value is calculated as follows:
Step 1: Determine the fair market value at the date of transfer.
Step 2: Determine the parent’s existing assessed value at the date of transfer.
Step 3: Compute the difference between fair market value and parent’s assessed value.
Step 4: If the difference is $1 million or less, the child’s new assessed value is the parent’s assessed value (no upward adjustment).
Step 5: If the difference exceeds $1 million, the child’s new assessed value is the parent’s assessed value plus the excess over $1 million.
Worked example: Parent bought a Carmel Valley home in 1990 for $250,000. The current Prop 13 assessed value is $400,000. The home’s current market value is $1.8 million.
Difference between market and assessed: $1.8 million minus $400,000 = $1.4 million. Excess over $1 million: $1.4 million minus $1 million = $400,000. Child’s new assessed value: $400,000 (parent’s) plus $400,000 (excess) = $800,000.
The child pays property tax on $800,000 instead of $1.8 million, but $400,000 more than the parent paid on.
The $1 million cap is adjusted every two years for inflation by the Board of Equalization. The current figure is published on the BOE website.
How Did Prop 19 Help Homeowners 55 and Older?
Before Prop 19, homeowners 55 and older (and severely disabled persons) could transfer their existing assessed value to a replacement home only if:
The replacement home was within the same county (Prop 60), or in one of about 10 participating counties (Prop 90).
The replacement home cost equal to or less than the original home’s sale price.
The transfer happened only once in a lifetime.
After Prop 19, the rules are dramatically more generous:
The replacement home can be anywhere in California (no county restriction).
The replacement home can cost more than the original home; the assessed value is adjusted to reflect the increase, but the assessed value still moves with the homeowner.
The transfer can be used up to three times in a lifetime (once for victims of natural disasters or contamination, regardless of age).
This change is one of the most significant benefits of Prop 19 for retirement-age homeowners who want to downsize, relocate to be near family, or move to a different California region without losing decades of property tax base.
Who Qualifies for the Base Year Value Transfer Under Prop 19?
To qualify for the expanded base year value transfer, the homeowner must meet one of three criteria:
Age 55 or Older: The homeowner (or the homeowner’s spouse) must be 55 or older at the time of the original residence’s sale.
Severely Disabled: The homeowner must qualify under California Revenue and Taxation Code Section 74.3 as severely and permanently disabled.
Victim of Wildfire or Other Disaster: The homeowner’s original residence must have been substantially damaged or destroyed by wildfire or a natural disaster declared a disaster by the Governor.
The replacement home must be purchased or newly constructed within two years before or after the sale of the original residence.
A Claim for Transfer of Base Year Value (BOE-19-B for transfers between counties, BOE-19-V for victims of disaster) must be filed with the county assessor where the replacement home is located, within three years of the replacement purchase.
What About the Grandparent-Grandchild Exclusion?
Prop 19 retained the grandparent-grandchild exclusion but narrowed it to mirror the parent-child rules. Under the new rules:
The transfer must be to a grandchild whose parents are both deceased at the time of transfer (the same requirement as under Prop 193).
The transferred property must be the grandparent’s primary residence (or a family farm).
The grandchild must establish the property as their own primary residence within one year and file the required forms.
The same $1 million cap applies.
Transfers from grandparents to grandchildren whose parents are still living do not qualify for the exclusion. Transfers of non-primary-residence property from grandparents to grandchildren are reassessed at full market value.
The grandchild files a Claim for Reassessment Exclusion (BOE-19-G) with the county assessor.
How Does Prop 19 Affect Inherited Rental Properties and Second Homes?
The clearest loss under Prop 19 is the elimination of the parent-child exclusion for non-primary-residence property.
Before Prop 19, parents could transfer rental properties, vacation homes, second homes, and other non-primary-residence real estate to children with up to $1 million of assessed value protected (per parent). After Prop 19, all of this is reassessed at fair market value at the date of transfer.
The practical impact is significant. A San Diego rental property assessed at $300,000 with an annual property tax bill of about $3,500 might be reassessed at $1.4 million after inheritance, producing an annual property tax bill of about $17,500. The increase frequently changes whether the inherited property is a viable investment for the new owner.
Families with appreciated rental property are now reconsidering their plans. Some are selling property during the parents’ lifetime. Some are using LLC structures and sales to children at fair market value, accepting the reassessment but locking in current values rather than future values. Some are simply accepting the higher tax bills as a cost of inheritance.
There is no clean workaround. Prop 19’s elimination of the exclusion for non-primary-residence property is intentional and has survived legal challenges so far.

Frequently Asked Questions About California Proposition 19
Q: Does Prop 19 apply to inheritances from before February 16, 2021?
A: Generally no. Transfers that took place before February 16, 2021 are governed by the prior rules. Transfers on or after that date are subject to Prop 19.
Q: Can I avoid Prop 19 by putting my property in a trust now?
A: Putting property into your own revocable trust does not trigger reassessment (California Revenue and Taxation Code Section 62), but it does not lock in Prop 58 rules either. When the property eventually transfers from your trust to your children at your death, Prop 19 applies.
Q: What if I die before my child can move into the inherited home?
A: The child has one year from the transfer date to establish primary residence. The transfer date is generally the date of the trustmaker’s death for a trust distribution, or the date of probate distribution.
Q: Can my child rent out the home and still claim the exclusion?
A: No. The exclusion requires the child to use the home as their own primary residence. Renting it out (even part of it) typically disqualifies the exclusion.
Q: How do I prove primary residence?
A: Through the Homeowners’ Exemption (BOE-266), and supporting documentation such as driver’s license address, voter registration, mailing address for tax returns, and utility bills.
Prop 19 reshaped California property planning. Allenby Law structures San Diego family transfers to take advantage of every exclusion and base year transfer the new law still allows. Schedule a consultation.
