Understanding Prop 13 Assessment

California only allows two things that initiate a re-assessment: transfer in ownership (also called a transfer) and new construction. A transfer in ownership is when any part of the ownership interest in the home has changed whether money changed hands or not. The Assessorss Office will review the transfer to see if its re-assessable. If it’s an assessable change in ownership, the data is sent to the appraisal staff to give or review the value and modify the base value appropriately. A change in ownership that isn’t assessable must have fallen within the parameters of an approved exemption. A transfer into a revocable trust or an inter-spousal transfer that are both examples of exemptions allowed in California articulated in our Inherited Property and Exemptions Guide detailed in the California Little Black Book.

When a transfer is exempt, the ONLY way the Assessorss Office knows this is through forms and/or applications which are recorded along with the deed or later requested by the Office of the Assessor to confirm an exempt transfer. So when there is no exemption, the transfer in ownership is considered assessable per Prop 13. Which means if you do not apply for the exemption, submit a form or offer accepted documentation for an exemption, the transfer is considered assessable automatically. The Office of the Assessor is a mass assessment organization and unless you tell them what you need preferably through forms and documents they wont know what may or may not apply to your change in ownership.

The other trigger for re-assessment based on Prop 13 is new construction. The Assessors’s Office is told by the city or county building and safety offices. The city or building and safety give the information about issued permits to the Office of the Assessor for property tax purposes. Keep in mind, your city receives some of your property tax dollars so though its primarily a state tax your local municipality benefits from it. The permits are given to the real property appraisers to update the building record and change the base value if warranted based on Prop 13. Normally, it takes the Assessors’s Office a fair amount of time to get to since field work is necessary to find out what was done to your house and then a valuation process. If there is a demo, your property taxes will likely be reduced, if there is an addition there is likely going to be an go up. So, if you demolish a pool your property taxes will decrease and if you add a pool, your property taxes will increase. Construction varies from home to home and it will be reviewed based on the value that was added or taken away. This is clearly explained in the California Little Black Book with examples and scenarios. When was employed by the Assessor I assessed countless homes where various types of construction was done and would be happy to answer any questions you may have pertaining to this!

Like new construction there will be a re-assessment of a property if the use of it changes. For example if a complex of co-ops is converted into condominiums the Assessor will reassess the value of each unit because the change affects the market value of each unit. However, generally in California there are two events that trigger re-assessment based on Prop 13: change in ownership or new construction.
