Frequently Asked Questions

If construction is started, will it change the amount due on my next property tax bill?

It depends on whether square footage will be added, the type of construction, and the stage of completion as of the preceding January 1. For further clarification, please contact the Regional Assessor’s Office at the address and phone number on your property tax bill.

Do I still owe the tax if some or all of the structures on my property are damaged, destroyed, or demolished?

Yes, you would still owe the full amount on the current tax bill, unless it results from a calamity or misfortune beyond your control such as a plane crash, earthquake, etc. However, depending on when and if the structures are repaired or replaced, the amount owed for future tax years may be reduced or eliminated.

Are properties owned by non-profit business, religious, or charitable organizations exempt from the assessment?

No, they are not. Only improvements used for parking, and government owned properties that are not leased to private entities, are exempt from the assessment.

Are senior citizens, disabled persons, or low-income homeowners exempt from the assessment?


Are the due dates, payment options, and penalties for this assessment the same as for the other portions of my tax bill?


If there is an error in the amount of the assessment, will I receive a refund?

Yes, if correction of the error would result in a refund of at least $1.00. In either case, correction of the error would be reflected in your future property tax bills.

What if I disagree with the square footage used to calculate the assessment?

Download an Assessment Adjustment Request form. Forms are also available at your Regional Assessor’s Office and at the public services counters in the Kenneth Hahn Hall of Administration Building, located at 500 W. Temple Street, Los Angeles, CA 90012. Nonetheless, the amount reflected on the property tax bill must be paid in full by the dates indicated on the bill to avoid interest and penalties.

How was the square footage of the structures on my property determined?

It was obtained from the property records of the County Assessor’s Office. The Assessor calculates the square footage based on the exterior dimensions, rounded to the nearest square foot. The square footage used for the current tax year is available by looking up your property on the Los Angeles County Assessor’s website.

Will the amount of the assessment always be the same?

Not necessarily, future increases or decreases in the square footage or the tax rate could increase or decrease the amount. The County Board of Supervisors may, by majority vote, increase or decrease the tax rate. Increases to the tax rate are limited to the cumulative increases, if any, in the medical component of the Western Urban Consumer Price index (CPI). The Fiscal Year 2023-24 rate of $0.05 reflects CPI increase only up to March 2022. 

How is the assessment calculated?

For Fiscal Year 2023-24, it is set at 5.00 cents (or $0.05) per square foot of structural improvements on the property. For example, for a property with a 1,500 square feet house on it, 1,500 would be multiplied by $0.05 resulting in an assessment of $75.00. Improvements used for parking are exempted from the assessment.

How long will this assessment last?

The assessment is an ongoing special tax which will continue permanently unless repealed by the voters of Los Angeles County.

How were the funds allocated?

For Fiscal Year 2023-24, a total budget of $386.7 million was allocated as follows: County hospitals, $208.5 million; Non-County hospitals and physicians, $87.8 million; Trauma Access through air transport, $4.4 million; County & City Public Health, $17.7 million; Emergency Medical Services Agency, $4.0 million; County and City Fire Departments, $0.2 million; Non-Hospital Private Entities, $37.3 million; County Auditor-Controller – administrative services, $0.8 million; Reserve, $26.0 million for future obligations.
