Proposition 13, also known as Prop 13, is a landmark property tax law in the state of California. It was passed by voters in 1978 and introduced significant changes to the property tax system. Here is an overview of Prop 13:


Background: Prop 13 was a response to rising property taxes in California during the 1970s. Many homeowners and businesses were facing substantial increases in their property tax assessments, leading to concerns about affordability and the ability to remain in their homes or operate their businesses.


Property Tax Limitations: The key feature of Prop 13 is that it limits property tax assessments to 1% of the property’s assessed value at the time of purchase. The assessed value can only increase by a maximum of 2% per year, regardless of changes in market value. This means that property taxes are generally stable and predictable for property owners, even if property values increase significantly over time.


Reassessment upon Sale: When a property is sold or changes ownership, Prop 13 requires a reassessment of the property’s value for tax purposes. The new assessed value is based on the sale price or fair market value at the time of transfer. Once reassessed, the property’s value is subject to the 1% tax rate and 2% annual increase limitation until the next sale or transfer occurs.


Benefits and Criticisms: Prop 13 has been praised for providing property tax relief to homeowners and creating stability in tax assessments. It has also been credited with protecting long-time homeowners from being priced out of their homes due to rising property values. However, critics argue that Prop 13 has resulted in reduced revenue for local governments, leading to challenges in funding essential services such as education and infrastructure.


Commercial Property Assessments: One significant aspect of Prop 13 is that it also applies to commercial properties. This means that commercial properties, including retail stores and office buildings, also benefit from the 1% tax rate and limited increases in assessed value. However, there have been ongoing discussions about potentially reforming Prop 13 for commercial properties to increase tax revenue.


Voter Approval for Tax Increases: Prop 13 also introduced a requirement that any new or increased local taxes, including special assessments and bonds, must be approved by a two-thirds majority of voters. This provision has made it challenging to raise local taxes for specific purposes, as it requires significant voter support.




    In summary, Prop 13 is a significant property tax law in California that limits property tax assessments to 1% of the assessed value at the time of purchase, with an annual increase cap of 2%. While providing stability for property owners, it has also raised debates about its impact on local government revenue and potential reforms for commercial properties.
