Prop 19 dramatically narrowed the parent-child Prop 13 inheritance exclusion in 2021, and the 2026 reality for Chatsworth families inheriting property is much tighter than what the prior rules allowed. I'm Brian Cooper at eXp Realty, and this is the plain-English explainer for what heirs and parents need to know about transferring Chatsworth real estate without triggering reassessment.
The Pre-Prop-19 Rules (Now Gone)
Before Prop 19 took effect in February 2021, parent-child transfers of California real estate received broad Prop 13 protection. The parents' assessed value transferred to the children without reassessment, on both primary residence and rental property, with no residence requirement.
Many Chatsworth families used this to pass long-held real estate to the next generation while preserving multi-decade Prop 13 assessment savings. That structure largely ended in February 2021.
The Current Prop 19 Rules
Parent-child transfers now avoid reassessment only on the parents' primary residence, only if the inheriting child makes the home their own primary residence within one year of transfer. Even then, if the market value at transfer exceeds the parents' assessed value by more than $1 million, the excess is added to the new assessed value.
Non-primary-residence inherited property (rentals, vacation homes, commercial) reassesses fully at market value. The pre-Prop-19 broad exclusion is gone for these categories.
The $1 Million Cap Math
Example: parents bought Chatsworth home in 1985 for $150K, current assessed value $300K, current market value $1.2M. Child inherits and makes it their primary residence within one year.
Calculation: market value ($1.2M) minus parents' assessed value plus $1M ($1.3M) = -$100K. Because market value is below the $1.3M threshold, the assessment transfers at $300K. The child pays property tax on $300K not $1.2M.
Alternate: same parents, same home, current market $1.6M. Calculation: $1.6M minus $1.3M = $300K excess. New assessed value = $300K (parents' base) + $300K (excess) = $600K. Tax on $600K, not $1.6M.
| Scenario | Parent Assessed | Market Value | Child New Assessed |
|---|---|---|---|
| Below cap | $300K | $1.2M | $300K (full transfer) |
| At cap exactly | $300K | $1.3M | $300K (full transfer) |
| Above cap | $300K | $1.6M | $600K (partial) |
| Far above cap | $300K | $2.5M | $1.5M (partial) |
The One-Year Primary Residence Requirement
The inheriting child must make the property their own primary residence within one year of the transfer date. They must file a homeowner's exemption claim with the LA County Assessor demonstrating primary occupancy.
If the child does not occupy as primary residence within one year, the property fully reassesses at market value as of the transfer date. The parents' Prop 13 base is lost. This is the most common Prop 19 trap — children plan to rent the inherited home or split it among siblings without one moving in, and lose the benefit.
Multiple Children
When multiple children inherit and only one will occupy as primary residence, the rules get complex. Generally, the occupying child can claim the exclusion for their proportional share of the property. The non-occupying siblings' shares face reassessment.
Common solution: buy-out structures where the occupying child purchases the non-occupying siblings' interests at fair market value, often with a portion financed against the property. This requires careful coordination with a CPA and an estate attorney.
Planning Implications
Chatsworth families with long-held real estate should plan now. The pre-Prop-19 broad exclusion is gone permanently. Options include: ensuring an heir is positioned to occupy as primary residence, considering lifetime gifts before death (with different tax implications), or accepting reassessment and planning for the resulting tax exposure.
Estate planning that worked before 2021 may not produce the intended Prop 13 outcomes now. Review every multi-property California estate plan with a CPA who specializes in Prop 19 post-implementation.
Frequently Asked Questions
What changed in Prop 13 inheritance under Prop 19?
Before February 2021, parent-child transfers received broad Prop 13 protection on all real estate without residence requirement. Under Prop 19, only the parents' primary residence qualifies for exclusion, only if the inheriting child makes it their own primary residence within one year, and only up to parents' assessed value plus $1 million.
What happens to inherited rental property?
Inherited rental property and other non-primary-residence properties fully reassess at market value as of the transfer date under Prop 19. The pre-2021 broad exclusion that protected rentals from reassessment is no longer available. Families with rental real estate should plan for the tax impact at inheritance.
How does the $1 million cap work?
If market value at transfer exceeds parents' assessed value plus $1 million, the excess is added to the new assessed value. Example: parents assessed at $300K, market value $1.6M. Calculation: $1.6M minus ($300K + $1M cap) = $300K excess. New assessed value = $300K + $300K = $600K.
What if multiple children inherit?
Generally only the occupying child can claim the exclusion for their proportional share. Non-occupying siblings' shares reassess at market. Common solution: the occupying child buys out non-occupying siblings at fair market value, sometimes with property-secured financing. Coordinate with a CPA and estate attorney.
Should I update my estate plan after Prop 19?
Yes. Any California estate plan written before February 2021 that assumed broad parent-child Prop 13 exclusion needs review. The pre-Prop-19 structures often no longer produce intended outcomes.
