What is RP-87-Spanish?
Form RP-87-Spanish, Decline-in-Value Application Spanish, is the Spanish-language application that property owners send to the Los Angeles County Office of the Assessor to request a temporary reduction in assessed value for 2026 because the property's market value has declined.
The form explains the test in its own terms: a decline in value exists when the market value of the property is lower than its assessed value as of January 1, 2026. The best evidence an owner can offer is information on sales of comparable properties, and the form has two rows for them. Including sales helps the Assessor determine market value, but the form says the request will not be rejected if no sales are listed.
The form collects the owner's contact data, the property address and Assessor's identification number (map book, page, parcel), the owner's opinion of value as of January 1, 2026, a description of the property, the comparable sales, and optional agent details. Signature lines are provided for the owner and for an agent.
The page also summarizes the assessment appeal process before the Assessment Appeals Board (AAB). An appeal is not filed with the Assessor. The Assessor's forms page also lists the English version, RP-87, Decline-in-Value Application.
Who needs to file RP-87-Spanish?
Owners of property in Los Angeles County whose property's market value has fallen below its assessed value as of January 1, 2026 may be eligible for a temporary reduction and use this form to ask for it. The form has room for single-family and multiple-residence properties (with number of units) and also gives guidance for commercial/industrial properties.
An agent or agent company may act for the owner. The form has fields for the agent's name or company, daytime phone, mailing address and email, and it tells you to attach the authorization as agent. The form carries separate signature and date lines for the owner and the agent.
You do not need to have comparable sales in hand to apply: the form states that the request will not be rejected if sales are not included. This page covers the Spanish-language form; owners who prefer the English text can look for RP-87 on the Assessor's forms page.
The form does not set other eligibility rules; for questions, it gives the Assessor's phone numbers 213.974.3211 and 1.888.807.2111.
When to file RP-87-Spanish
The Assessor's office must receive this form between July 2 and November 30, 2026. Applications are valid if postmarked no later than November 30, 2026, and requests not received on time cannot be processed.
The form also asks you to keep a copy of the application as a reminder: if you have not received the Assessor's result by October 1, 2026, you may need to file an assessment appeal. If you disagree with the Assessor's result on the reduction, you may appeal to the Assessment Appeals Board (AAB); for the 2026 "Regular Assessment Roll" a formal appeal may be filed from July 2 to November 30, 2026. For a "Corrected Assessment Roll," an appeal may be filed within 60 days of the later of the mailing date printed on the tax bill or the date of the tax bill. You can appeal before the deadline without waiting for an answer to this request. The form does not state a processing time.
Documents you need
- Supporting data or additional information that backs up your request; the form tells you to attach it, and sales of comparable properties are the best evidence it names.
- Authorization as agent, only if an agent or agent company is named on the form and acts for the owner.

How to submit RP-87-Spanish
The form names one submission channel, mail, and one way to follow up, the Assessor's website.
- By mail: send the completed, signed application to Los Angeles County Assessor, 500 West Temple Street, Room 286, Los Angeles, CA 90012-2770 (Oficina del Tasador). It must be received between July 2 and November 30, 2026, and a postmark of November 30, 2026 or earlier keeps it valid.
- Attachments: include any supporting data or additional information for your request, and the authorization as agent if an agent signs.

- Help: call 213.974.3211 or 1.888.807.2111.
Keep a copy for your records. An assessment appeal is a separate step and is not filed with the Assessor: from July 2, 2026 you can request the AAB application at 213.974.1471 or online at bos.co.la.ca.us.
FillingPDF lets you fill out and download the PDF; submission follows the Assessor's channels above.
Common mistakes to avoid
- Mailing the application so that it is not received or postmarked by November 30, 2026; requests not received on time cannot be processed.
- Sending it so that it arrives before July 2, 2026, when the form says it must be received between July 2 and November 30, 2026.
- Listing comparable sales that took place after March 31, 2026; the form asks for sales around January 1, 2026, not later than March 31, 2026.
- Not keeping a copy of the application, which the form says serves as a reminder to appeal if no result arrives by October 1, 2026.
- Waiting for the Assessor's answer past the appeal deadline; you may appeal without waiting for a response, and the 2026 regular-roll deadline is November 30, 2026.
- Sending an Assessment Appeals Board appeal to the Assessor; the form marks appeals as not filed with the Assessor.
- Naming an agent without attaching the authorization as agent that the form calls for.
- Leaving the application unsigned; the form has signature and date lines for the owner and, where applicable, the agent.
