Under Proposition 19, an inherited rental property, second home, vacation home, commercial building, or investment land receives no exclusion at all and is reassessed to full market value. Only two kinds of property can keep a parent’s low tax base: a family home the heir moves into within one year, and a qualifying family farm, which carries no occupancy requirement at all. Grandparent-to-grandchild transfers follow the same rules, plus one added condition: the middle generation must be deceased.
Key Facts
- Inherited rentals and second homes get no exclusion. They are reassessed to current market value on the date of transfer.
- Commercial buildings, industrial property, and investment land are treated the same way, with no cap to soften the increase.
- The old $1 million shelter for non-residence property, which each parent once had under Proposition 58, no longer exists in any form.
- A family farm can keep its low base when inherited, subject to the value cap, and nobody has to live on it.
- A family farm is defined by agricultural use, not by size or label: land under cultivation, used for pasture or grazing, or producing an agricultural commodity.
- Grandparent-to-grandchild transfers require that the grandchild’s parents who are the grandparents’ children all be deceased. A stepparent who is not a child of the grandparents does not need to be.
What Happens to an Inherited Rental or Second Home?
It is reassessed to full market value, and nothing the heir does afterward can undo it.
This is the cleanest break from the old rules. Under Proposition 58, a parent could pass a rental or vacation home and the child kept the low base without ever living there. That option is gone. The moment the property changes hands, the assessor resets its taxable value to the current market price.
The cost is steep. Consider a rental with a factored base year value of $150,000 and a market value of $900,000. Under the old rules, the child kept the low base and paid tax on $150,000, roughly $1,500 a year at the basic one percent rate. Under Proposition 19, the child pays tax on $900,000, roughly $9,000 a year. That is a $7,500 annual difference on a single property, for as long as the family holds it.
There is no move-in option here, because a rental was never the parent’s principal residence. The property simply falls outside the benefit.
Does the Same Rule Apply to Commercial Property?
Yes. The rule reaches well beyond homes.
Commercial buildings, industrial property, raw land held for investment, and any other property that is not a family home or a qualifying family farm all fall outside the exclusion. There is no partial protection and no cap to soften it. These property types reassess to market value on transfer exactly as a rental does.
So for most inherited investment real estate, the planning question is no longer how to keep the low base, because you cannot. The question becomes whether to hold or sell, and how the higher tax bill weighs against the property’s income. Chapter 12 takes up that decision.
What Makes a Family Farm Different?
Family farms are the one kind of non-residence property Proposition 19 still protects, and they carry a rule the family home does not.
A family farm can pass from parent to child, or from grandparent to grandchild, and keep its low base, subject to the same value cap that applies to a family home. But no one has to live on it. The family home requires the heir to move in within a year. A family farm carries no occupancy requirement whatsoever. The heir keeps the low base without making it a residence.
What counts as a family farm is defined by use, not by acreage or by what the deed calls it. It is real property under cultivation, or used for pasture or grazing, or used to produce any agricultural commodity.
The value cap still applies, measured for each legal parcel of the farm. A very valuable farm can face a partial reassessment on the value above the limit, just as a high-value home does. Chapter 9 covers how that cap is calculated.
How Do Grandparent-to-Grandchild Transfers Work?
Proposition 19 kept a path from grandparents to grandchildren, and it now mirrors the parent-child rules with one extra condition on top.
A grandparent’s family home qualifies if it was the grandparent’s principal residence and the grandchild moves in within one year and claims the homeowners’ exemption. A grandparent’s family farm qualifies with no occupancy requirement. The same value cap applies to both.
The extra condition governs every grandparent-to-grandchild transfer: the grandchild’s parents who are children of those grandparents must all be deceased as of the date of the transfer. This is the middle generation. If that generation is still living, the exclusion does not apply and the property reassesses.
A narrow exception softens this. A stepparent who is not a child of the grandparents does not need to be deceased for the transfer to qualify.
To claim the exclusion, the family files form BOE-19-G, the grandparent-grandchild counterpart to the parent-child form BOE-19-P.
Which Box Does Your Property Fall Into?
These cases share a single logic. Proposition 19 protects a low tax base only for a family home an heir lives in, or a qualifying family farm. Everything else reassesses.
Hold the categories side by side:
- A parent’s home passing to a child who moves in keeps the low base, subject to the cap.
- A family farm keeps the low base with no one living on it, subject to the cap.
- A rental, vacation home, commercial building, or investment land keeps nothing and reassesses to market value.
- A grandparent’s home or farm can qualify too, but only when the middle generation has died.
Knowing which box a property falls into tells you almost everything about its tax future. Chapter 11 adds the traps that can reassess even a qualifying property by accident, through co-owners, buyouts, trusts, and business entities.
Summary
- Inherited rentals and second homes get no exclusion under Proposition 19 and are reassessed to full market value.
- Commercial property, industrial property, and investment land also fall outside the exclusion, with no cap to soften the reassessment.
- The old one-million-dollar shelter for other property is gone in every form.
- A family farm can keep its low base when inherited, subject to the value cap, and unlike a family home it carries no requirement that anyone live on it.
- A family farm is defined by agricultural use: land under cultivation, used for pasture or grazing, or producing an agricultural commodity, with the cap applied per legal parcel.
- Grandparent-to-grandchild transfers follow the same family-home and family-farm rules, using form BOE-19-G.
- A grandparent-to-grandchild transfer also requires that the middle generation all be deceased, though a stepparent who is not a child of the grandparents need not be.
