Effective rate, median annual bill, homestead exemption, and assessment cap rules under Cal. Const. art. XIII A
Median bill is the actual ACS 2022 figure for owner-occupied housing units in California. Your specific bill will vary by county and municipality, local mill rates can swing the effective rate by 30%+ within a single state.
California is a low-effective-rate property tax state on paper, but the way rentals are assessed changes the math for landlords. The Tax Foundation puts California's effective property tax rate on owner-occupied housing at 0.70% of value, below the national average of roughly 1.1%. That low rate is a product of Proposition 13 (1978), which caps the base ad valorem rate at 1% of assessed value and limits annual increases to 2% until the property changes hands. For a rental owner, the two facts that matter most are that your assessed value is locked to your purchase price, and that the tax breaks California extends to homeowners largely do not reach investment property.
Proposition 13 sets the base property tax rate at 1% of a property's assessed value, plus whatever is needed to service voter-approved bonded debt (California State Board of Equalization, Publication 29). The headline rate is 1%, but the number a landlord writes a check for is usually higher. Once local voter-approved bonds, parcel taxes, and Mello-Roos community facilities district charges are layered on, actual bills commonly run 1.1% to 1.3% of assessed value. The exact load depends on the parcel: two rentals a mile apart can carry different effective rates because they sit in different bond and special-assessment districts. County-level medians reflect this spread, ranging from roughly 0.54% in Trinity County to about 0.91% in Kern County (Tax Foundation county data). Before you underwrite a deal, pull the actual tax bill for the parcel rather than applying a flat 1%.
California uses an acquisition-value system, and it applies to rentals the same way it applies to homes. When you buy a rental, the county assesses it at your purchase price, and that assessed value can rise no more than 2% per year regardless of how far market rents or comparable sales climb. A rental bought years ago at a low basis carries a tax bill that can be a fraction of what a neighboring building that just sold pays on identical square footage. This is the core Prop 13 advantage for buy-and-hold landlords: your largest fixed operating cost is anchored to your cost basis and grows slowly and predictably. The flip side is that the discount is not portable to a buyer. When you sell, the property reassesses to the new purchase price, so a long-held building's low tax bill does not transfer, and a buyer must underwrite the reset rate.
California's $7,000 homeowners' exemption reduces the taxable value of an owner's principal residence, but it is available only for owner-occupied homes. Rentals and vacation homes do not qualify (California State Board of Equalization). The dollar impact is modest, roughly $70 to $91 a year at typical rates, but it is a clean example of a broader pattern: the property tax relief California builds for resident homeowners is written around owner-occupancy, and investment property sits outside it. There is no rental-specific assessment ratio that offsets this in California; a rental and an owner-occupied home of the same assessed value are taxed on the same 1%-plus base, with the resident home getting the small exemption on top.
Proposition 19, effective February 16, 2021, closed the door that once let families pass rental property down at its old tax basis. The parent-child reassessment exclusion now applies only to a family home that was the transferor's principal residence and becomes the transferee's principal residence, or to a family farm (California State Board of Equalization, Prop 19). A rental or vacation property inherited by a child is fully reassessed to current market value at transfer. Even for a qualifying primary residence, the excluded amount is capped: the exclusion covers the prior base value plus an inflation-indexed figure set at $1,044,586 as of February 16, 2025, and the child must occupy the home as a principal residence within one year or lose the exclusion. For landlords planning succession, this means a low-basis rental portfolio can face a sharp property tax step-up the moment it changes hands, which is a real number to factor into estate and hold-versus-sell decisions.
Net the pieces together. California's effective rate on housing is low by national standards, and Prop 13's 2% cap makes property tax the most predictable line in a California rental pro forma once you own the asset. That predictability is worth real money over a long hold and partly offsets the state's high acquisition prices and tenant-protective regulatory climate. The offsets are on the entry and exit sides: you buy at reset value, so a hot submarket's tax bill reflects today's price, not a legacy basis; you get no homeowners' exemption; and any transfer, sale or inheritance, generally reassesses the property to market. The practical takeaways are to underwrite the parcel's actual current bill, not a flat 1%; model the 2% annual escalator rather than assuming flat taxes; and treat a Prop 19 reassessment as a planned event, not a surprise, when structuring how the property will eventually pass on.
Proposition 13, base year value capped at 1% of 1975 (or purchase) value; reassessed only on sale or new construction, with annual growth limited to 2%.
The exemption is granted under Cal. Const. art. XIII A. To claim it, owner-occupants must typically file an application with the county assessor (most states require filing once, with renewal triggered only by change of ownership or use). Failure to file the application means full taxation at the non-homestead rate.
This page reflects California property tax law as administered under Proposition 13 (1978) and Proposition 19 (2021), drawing on the California State Board of Equalization (Publication 29, March 2025, and the Proposition 19 materials at boe.ca.gov/prop19) and effective-rate data from the Tax Foundation. Rate figures cited are the effective property tax rate on owner-occupied housing (0.70% for California) and the applicable statutory caps; individual parcels vary with local bonds, parcel taxes, and Mello-Roos districts. This is general information for rental owners, not tax or legal advice. Confirm the current assessed value and tax bill for a specific parcel with the county assessor, and consult a California tax professional before making acquisition, sale, or estate decisions.
Rentals are taxed under the same Proposition 13 rules as homes: a 1% base rate on assessed value plus voter-approved bonds and special assessments, so actual bills commonly run 1.1% to 1.3%. California's effective rate on owner-occupied housing is 0.70% per the Tax Foundation, below the national average of about 1.1%; rentals are assessed on the same 1%-plus base but without the homeowners' exemption.
By acquisition value. The county assesses the property at your purchase price, and that assessed value can rise no more than 2% per year under Proposition 13 until the property changes ownership, regardless of market appreciation. This applies identically to rentals and owner-occupied homes.
No. The $7,000 homeowners' exemption applies only to an owner's principal residence. Rentals and vacation homes do not qualify, per the California State Board of Equalization. That gap is worth roughly $70 to $91 a year at typical rates.
Yes. Under Proposition 19 (effective February 16, 2021), the parent-child exclusion applies only to a family home used as the principal residence by both parent and child, or a family farm. An inherited rental or vacation property is fully reassessed to current market value at transfer.
No. Selling a rental is a change in ownership that reassesses the property to the new purchase price. A long-held building's low Prop 13 tax basis does not carry over, so a buyer must underwrite the reset, market-value tax bill.
California's effective rate on owner-occupied housing is about 0.70%, below the roughly 1.1% national average, and the 2% annual cap makes the bill highly predictable over a long hold. The trade-offs for investors are reassessment to market value at purchase and transfer, and no homeowners' exemption on rentals.
