Yes, Proposition 13 does apply to rental property in California, and it applies with the same force as it does to an owner-occupied home. The base property tax rate is capped at 1% of the purchase price, and the assessed value can rise by no more than 2% a year regardless of what the market does. The catch for landlords is that several events reset that protection, and one of them, inheritance of a rental, changed drastically in 2021.
How the Cap Works on a Rental
Two rules do the work. Article XIIIA of the California Constitution limits the base ad valorem rate to 1% of a property’s full cash value.1FindLaw. California Constitution Article XIIIA – Section 1 Voter-approved bonds and parcel taxes can add to your bill, but the base levy stays at 1%.2California State Board of Equalization. California Property Tax An Overview – Publication 29
The second rule anchors the taxable amount. Your rental’s assessed value starts at the purchase price, called the base year value, and the assessor can raise it each year only by the lesser of 2% or the change in the California Consumer Price Index.3California Legislative Information. California Revenue and Taxation Code – Section 51 If rents and property values in your neighborhood climb 10% in a year, your taxable value still moves by at most 2%. Hold the property long enough and the gap between taxable value and market value becomes the heart of the Prop 13 benefit for a landlord.
That capped value stays in place until something resets it. Only two kinds of events do: a change in ownership or new construction.
What Resets the Assessment on a Rental Property
Selling the Property
A “change in ownership” under Revenue and Taxation Code Section 60 covers any transfer of a present interest in real property where the value transferred is substantially equal to the fee interest.4California Legislative Information. California Revenue and Taxation Code – Section 60 A sale is the obvious example. The buyer’s purchase price becomes the new base year value, which is why an investor buying a fourplex today pays a far larger tax bill than the owner who bought it in 1990.
If you own a rental with co-tenants and one of them sells to an outside party, only that transferred share resets. The remaining owners keep their existing base year values on their shares.
Entity Ownership Changes
Many landlords hold rentals inside LLCs, partnerships, or corporations, and interests in those entities can change hands without the deed ever moving. California still treats some of those shifts as a change in ownership.
The first trigger is a change in control: any single person or entity obtains more than 50% of the total ownership interest in the entity.5California Legislative Information. California Revenue and Taxation Code – Section 64 When that happens, every piece of California real property the entity owns gets reassessed to current market value.6California Board of Equalization. Legal Entity Ownership Program – Definition of Change in Ownership It’s a full reassessment, not partial, and multi-step deals sometimes cross the line without anyone noticing.
The second trigger is the original co-owner rule. When property was originally transferred into the entity using the proportional-interest exclusion, the people who held interests at that moment become “original co-owners.” If those original co-owners cumulatively transfer more than 50% of the entity’s interests, the property gets reassessed on the date the cumulative total crosses the threshold, even if no single buyer took control.5California Legislative Information. California Revenue and Taxation Code – Section 64 Three partners each selling 20% to different buyers over several years is the classic trap.
Long-Term Leases
Signing a lease with a term of 35 years or more, counting renewal options, counts as a change in ownership.7California Legislative Information. California Revenue and Taxation Code – Section 61 Only the leased portion of the property gets reassessed.8California State Board of Equalization. Property Tax Annotations – 220.0357 This mostly affects commercial and ground-lease deals, but a shorter lease later extended past the 35-year line triggers reassessment at the time of extension.
New Construction
New construction on a rental triggers reassessment of the new portion only. The statute covers any addition and any alteration that converts the property to a different use or amounts to a major rehabilitation, essentially making the improvement the functional equivalent of a new one.9California Legislative Information. California Revenue and Taxation Code – Section 70 The new construction gets its own base year value at current market value, and that value is added to the existing capped value of the original building. Add two units to a fourplex and the original four units keep their low basis while the two new units start fresh.
Routine upkeep doesn’t count. Replacing a roof with a comparable roof, repainting, or fixing plumbing preserves the existing assessment. Gut-renovating a kitchen or adding square footage does not. The line between repair and major rehabilitation is where most disputes arise, and it often turns on whether the work extended the useful life of the improvement beyond what it was before.
Inheriting a Rental After February 16, 2021
This is the change rental owners most need to understand. Before February 16, 2021, parents could transfer rental properties to their children with no reassessment, preserving decades of Prop 13 savings. Proposition 19 ended that exclusion for everything except a primary residence and qualifying family farms.10California Legislative Information. California Revenue and Taxation Code – Section 63.2
A rental, whether a single-family home, duplex, or fourplex, inherited after that date gets fully reassessed to current market value. No dollar threshold, no partial exclusion. A property purchased in the 1980s with a base year value of $150,000 and a current market value of $1.5 million can jump from roughly $1,500 a year in property tax to roughly $15,000 practically overnight when it passes to a child. Any estate plan built around passing low-basis rentals to heirs needs to be revisited with that math in mind.
The primary-residence version of the exclusion still exists, but the child has to move in as their principal residence within a year of the transfer and claim the homeowners’ or disabled veterans’ exemption within that same window.11California State Board of Equalization. Proposition 19 Fact Sheet – Intergenerational Transfer Exclusion Even then, if the home’s market value exceeds the factored base year value by more than a set threshold, the excess is added to the assessment. For transfers between February 16, 2025, and February 15, 2027, that threshold is the existing taxable value plus $1,044,586, adjusted every two years.12California State Board of Equalization. BOE Adjusts the Proposition 19 $1 Million Intergenerational Transfer Exclusion Amount None of that helps a rental.
Exclusions Rental Owners Can Still Use
Proportional Interest Transfers
You can move a rental into or out of a legal entity without triggering reassessment if three conditions hold: the transfer is between individuals and the entity (or between entities), it only changes the method of holding title, and every transferor’s proportional ownership stays exactly the same afterward.13California Legislative Information. California Revenue and Taxation Code – Section 62 Two partners who each own 50% as tenants in common can contribute the property to an LLC held 50/50 with no reassessment.14California State Board of Equalization. Legal Entity Ownership Program – Exclusions for Reassessment
The percentages have to match for every property in the transaction, and they have to match for each property individually if more than one is being contributed. And the protection isn’t permanent: once the property sits inside the entity, if the original co-owners later transfer more than half of their combined interests, the reassessment you avoided at contribution comes back.
Revocable Trusts
Transferring a rental into a revocable living trust where you remain the sole present beneficiary is not a change in ownership. The base year value is preserved. Reassessment is deferred, not avoided; when the trust becomes irrevocable at your death and the property passes to a beneficiary, that transfer is a change in ownership, and the Proposition 19 rules on rental property apply at that point.
Moving a rental into an irrevocable trust typically does count as a change in ownership unless a statutory exclusion applies. What matters is who holds the beneficial interest after the transfer.
When Market Values Fall
Prop 13 caps how fast assessments rise, and Proposition 8 (codified in Section 51) addresses what happens when values fall. If the market value of your rental on January 1 drops below its factored base year value, the assessor is required to enroll the lower amount.15California State Board of Equalization. Decline in Value – Proposition 8 Many properties saw this during the 2008 downturn and again in the early pandemic.
The reduction is temporary. The assessor reviews the property each year, and a property in decline-in-value status can rise by more than 2% per year as the market recovers.15California State Board of Equalization. Decline in Value – Proposition 8 It just cannot exceed the original factored base year value absent a change in ownership or new construction. The Prop 13 value acts as a ceiling.
County assessors often reduce assessments on their own during broad downturns, but they can miss individual properties hit by localized problems like contamination, structural damage, or a declining block. If you think your rental’s market value has fallen below its assessed value and the assessor hasn’t adjusted it, you can file a decline-in-value application with the county. Deadlines vary but generally fall in the second half of the calendar year. A formal assessment appeal is available if the informal route doesn’t fix it.
Filing Obligations That Catch Landlords Off Guard
Two forms matter for rental owners, and one of them carries real money.
When a deed transferring real property is recorded, the buyer must file a Preliminary Change of Ownership Report with the county recorder at the same time. If it isn’t filed concurrently, the recorder can charge a $20 fee, and processing of any applicable exclusion may be delayed.
The expensive one is Form BOE-100-B. Whenever a change in control or change in ownership happens in a legal entity that holds California real property, the entity must file BOE-100-B with the State Board of Equalization within 90 days. It goes to the BOE, not the county assessor, and filing a change of ownership statement with the county does not satisfy the requirement.16California Board of Equalization. Legal Entity Ownership Program Filing Requirements and Penalty Provisions
Miss the 90-day deadline and the penalty is 10% of the taxes based on the new base year value from the reassessment. If no reassessment occurred, the penalty is 10% of the current year’s taxes on the property.17California Legislative Information. California Revenue and Taxation Code – Section 482 On a $2 million property that penalty easily reaches five figures. The form has to be filed even when an exclusion applies and even when the BOE ultimately decides no reassessment is warranted. When the change in ownership results from a death, the deadline runs 150 days from the date of death or, if the estate is probated, from the date the inventory and appraisal are filed.
Most investors assume that if no reassessment is owed, nothing needs to be filed. That assumption is where the penalty hits.
