Before Prop 19, California's parent-child exclusion was generous: parents could pass their primary residence (any value) to children with no reassessment, plus up to $1M of OTHER real estate (rentals, vacation homes) — also no reassessment. This let families keep low Prop 13 base year values for generations across multiple properties.
Prop 19 narrowed this dramatically in February 2021. The new rules are very different. If you stand to inherit a parent's home in Ventura County or Los Angeles County, understanding Prop 19 can save your family tens of thousands of dollars per year — or, if you miss the rules, cost you the same.
This guide explains general Prop 19 mechanics. It is not legal or tax advice. Every situation has nuances that affect outcomes — consult a California estate-planning attorney and CPA before relying on this for specific decisions.
What Prop 19 Actually Says (the Short Version)
For property transferred from parent to child after February 16, 2021:
Primary Residence Transfer
- Child must make it their PRIMARY RESIDENCE within 1 year of transfer (claim homeowners' exemption)
- The assessed value can be excluded from reassessment ONLY UP TO the parent's factored base year value PLUS $1,044,586 (2026 figure, indexed annually)
- Any value above that triggers reassessment of the EXCESS portion to current market value
Investment / Vacation / Rental Property Transfer
- NO parent-child exclusion. Property is reassessed to current market value at transfer.
Worked Example #1: Primary Residence Within Limits
Parent owns Simi Valley home with current market value of $850,000. Their factored base year value (the Prop 13 base) is $200,000.
Difference: $850K - $200K = $650K. Below the $1,044,586 exclusion ceiling.
Child inherits, makes it their primary residence within 1 year. Result: child's assessed value remains at $200,000. Annual property tax: $200,000 × 1.05% = $2,100/year (vs $8,925 if reassessed).
Annual savings: $6,825.
Worked Example #2: Primary Residence Exceeds Limits
Parent owns Wood Ranch home with current market value of $1,500,000. Factored base year value of $300,000.
Difference: $1,500K - $300K = $1,200K. EXCEEDS the $1,044,586 exclusion ceiling by $155,414.
Child inherits, makes it their primary residence within 1 year. Result: child's assessed value is $300,000 + $155,414 = $455,414. Annual property tax: $455,414 × 1.05% = $4,782 (vs $15,750 if fully reassessed).
Annual savings: $10,968 (still significant, but reduced compared to pre-Prop 19).
Worked Example #3: Rental Property Transfer
Parent owns rental property in Camarillo, current market value $750,000, factored base year value of $150,000.
Child inherits. Result: NO PARENT-CHILD EXCLUSION (rental property doesn't qualify under Prop 19). Property is reassessed to $750,000 market value. Annual property tax: $750,000 × 1.05% = $7,875 (vs $1,575 under pre-Prop 19 rules).
Annual cost increase: $6,300 — and the rental income may not cover the new tax burden.
Critical Rules and Deadlines
| Requirement | Details |
|---|---|
| Primary residence within | 1 year of transfer |
| Claim homeowners' exemption within | Same 1-year window |
| File for parent-child exclusion within | 3 years (deadline for protective filing) but should be done at time of transfer |
| Excluded value limit (2026) | Parent's base year value + $1,044,586 |
| Excluded value limit (annual indexing) | Adjusted by California CPI annually |
| Effective date for new rules | February 16, 2021 forward |
What's the Difference Between "Inherit" and "Transfer"?
Prop 19 applies to BOTH inheritance (after parent's death) and lifetime transfer (parent giving you the home while still alive). The rules and deadlines apply identically. Some families used to gift property to children during the parent's lifetime to start the new Prop 13 assessed-value clock; that strategy is now governed by Prop 19's stricter rules.
Strategies if You're Going to Exceed the Limit
If you'll inherit a high-value primary residence that exceeds the $1,044,586 exclusion ceiling:
- Accept the partial reassessment. Even with reassessment of the excess, you save substantially compared to a full reassessment.
- Sell the property and use the proceeds for something else. No Prop 19 implications if you don't keep the home.
- Move into the home and qualify for the exclusion on the eligible portion. Even partial savings are meaningful.
- Plan during parent's lifetime through irrevocable trust structures. Some advanced estate planning tools work AROUND Prop 19 — but require a qualified attorney to set up properly. Common in $5M+ estates.
What if I Don't Want to Live in the Inherited Home?
If you don't make the inherited home your primary residence within 1 year, NO parent-child exclusion applies. The property is fully reassessed to current market value. For a Wood Ranch home with $300K base value and $1.5M current value, that's an additional $12,600/year in property tax — possibly more than the rental income.
Decisions to make BEFORE the transfer:
- Will you actually live in the home within 1 year?
- If not, would selling now (capturing parent's stepped-up basis at death = no capital gains tax) be better than keeping?
- If multiple children inherit, who gets the primary-residence treatment?
Frequently Asked Questions
Can I claim the parent-child exclusion if I move into the inherited home immediately?
Yes — moving in immediately and filing for the homeowners' exemption within 1 year qualifies you for the exclusion (subject to the $1,044,586 limit on excess value above your parent's base year value).
What if I'm one of multiple siblings inheriting the home?
Only one sibling can claim the parent-child exclusion as primary residence. If multiple siblings inherit, you'll need to decide who takes primary residence — typically that sibling buys out the others' shares. Consult an estate attorney for the mechanics.
Does Prop 19 apply to grandparent-grandchild transfers?
Yes — same rules apply when grandchildren inherit from grandparents (assuming the grandchild's parent — the grandparent's child — is deceased). The same 1-year primary residence requirement and value limits apply.
My parent's house is worth less than the limit — am I safe?
Generally yes, but verify the math. The exclusion is parent's factored base year value PLUS $1,044,586. If parent's base value is $200K, total excludable value is $1,244,586. Most Simi Valley homes (median $849K) easily fit under this ceiling.
Can I rent out the inherited home and still get the exclusion?
No. Prop 19 explicitly requires primary residence (homeowners' exemption claim). Renting out the property disqualifies it from parent-child exclusion. The property is fully reassessed.
Does Prop 19 change the federal stepped-up basis?
No — Prop 19 is a California property tax rule. Federal stepped-up basis at death (eliminating capital gains tax for heirs) is unaffected. Selling an inherited property at the new stepped-up basis often produces zero federal capital gains tax.
What's the deadline to file for the parent-child exclusion?
Technically you have 3 years from transfer to file a protective claim, but the property is treated as reassessed UNTIL you file. Best practice: file at the time of transfer through the County Assessor's office. In Ventura County, contact the Assessor at (805) 654-2181.
