Every county runs the same free decline-in-value review, but each has its own form, deadline, and way to file. We do the analysis and prepare everything; then we either submit it for you or hand you a copy-ready page to finish in about two minutes. Here's the requirement for each, and exactly what we handle.
The county asks for its Informal Request for Decline in Market Value Reassessment with comparable sales.
We handle it by filling the form, collecting your e-signature, and submitting it to the Assessor.
The county asks for its Request for Value Review (Proposition 8) form with comparable sales supporting your opinion of value.
We handle it by filling the form, collecting your e-signature, and submitting it to the Assessor.
The county asks for its Decline-in-Value Review Application (RP-87) with your opinion of value and two comparable sales that closed on or before March 31, 2026.
We handle it by filling the county's own RP-87, collecting your e-signature, and printing and mailing it First-Class to the Assessor for you. You do nothing else. We close Los Angeles filings November 14 so every letter arrives well before the county's November 30 deadline.
The county asks for its Request for Informal Assessment Review with your opinion of value and comparable sales.
We handle it by filling the county's own form, collecting your e-signature, and emailing it to the Assessor's Office with you copied.
The county asks for its Request for Decline in Value Review with your parcel number, contact details and your opinion of value as of January 1. The form has no space for comparable sales, so your evidence travels as an attachment.
We handle it by filling the county's own form, attaching your comparable-sales worksheet, collecting your e-signature, and emailing it straight to the Assessor. Returning the form by email is printed on the form itself as an accepted way to file.
One thing to expect: Napa asks for requests by May 15 so it can finish reviewing before the assessment roll closes on June 30. The form still accepts filings through November 15, so a later filing is valid, but the county may act on it after the roll has closed. If your property was already reduced, the county tells you not to file again.
The county asks for its Value Review form (PCA552) with your opinion of value as of January 1, 2026, your current assessed value, and up to three comparable sales. Placer looks at sales between October 1, 2025 and March 31, 2026.
We handle it by filling the county's own PCA552, attaching your comparable-sales worksheet, collecting your e-signature, and printing and mailing it First-Class to the Assessor. We close Placer filings December 15 so every letter is postmarked well before the county's December 31 deadline.
One thing to expect: Placer automatically reviews any property that already received a Proposition 8 reduction and mails a notice each July, so if yours was reduced last year you do not need to file again. Note also that the county form carries no signature line, so your signature goes on the comparable-sales worksheet we attach.
The county asks for its Decline-in-Value Reassessment Application (ACR-755) with your parcel number, your opinion of value, and two comparable sales that closed on or before March 31, 2026.
We handle it by filling the county's own ACR-755, collecting your e-signature, and printing and mailing it First-Class to the Assessor for you. You do nothing else. We close Riverside filings October 18 so every letter arrives well before the county's November 1 deadline.
Good to know: if the county already reduced your assessment last year, Riverside reviews it again automatically this year. You may not need to file at all, so check your value notice first.
The county asks for its Decline-in-Market Value Request for Assessor Review (Prop 8) with your opinion of value as of January 1, 2026, your contact details, and up to two comparable sales that closed no later than March 31, 2026.
We handle it by filling the county's own 2026-27 form, attaching your comparable-sales worksheet, collecting your e-signature, and faxing it to the Assessor the moment you're done. You do nothing else. Sacramento's window runs July 1 through December 31, and the review is free.
The county asks for its Request for Decline-in-Value Review (Prop. 8) for residential properties, with your opinion of value as of January 1, your current taxable value, and up to four comparable sales. Sales after March 31 cannot be considered, and the county asks for open-market transactions only, so no short sales or foreclosures.
We handle it by filling the county's own form, attaching your comparable-sales worksheet, collecting your e-signature, and printing and mailing it to the Assessor. We close San Benito filings December 15 so every letter arrives before the county's December 31 deadline.
One thing to expect: San Benito's form includes consent to a property inspection directly above the signature line. Signing it agrees to let the Assessor's staff inspect the property, including the interior, and an appraiser would call to arrange a time. Filing after November 30 also gives up the formal appeal as a backstop for this year.
The county asks for its Application for Decline in Value Reassessment (ARP-068) with your opinion of value, your current assessment, and comparable sales attached as supporting evidence (sold on or before March 31, 2026).
We handle it by filling the county's own ARP-068, attaching your comparable-sales worksheet, collecting your e-signature, and printing and mailing it First-Class to the Assessor for you. You do nothing else. We close San Bernardino filings December 17 so every letter arrives well before the county's December 31 deadline.
The county asks for its Informal Assessment Review Request with your opinion of value and comparable sales that closed near January 1, 2026.
We handle it by filling the form, collecting your one e-signature, and submitting it to the Office of the Assessor-Recorder. You do nothing else.
Timing. San Francisco's informal review runs January 2 through March 31 each year. The 2026 window has closed and reopens January 2, 2027. A formal appeal with the Assessment Appeals Board is still open through September 15 as a backstop.
The county asks for its 2026-2027 Informal Request for Decline in Market Value Review with your opinion of value as of January 1, 2026, your 2026 assessed value, your purchase date and price, and up to three comparable sales sold no later than March 31, 2026.
We handle it by filling the county's own 2026-27 form, attaching your comparable-sales worksheet, collecting your e-signature, and printing and mailing it First-Class to the Assessor.
One thing to expect: San Joaquin's deadline is September 15, and metered mail carries no postmark, so your form has to arrive rather than simply be sent. We close filings August 31 to leave room for delivery.
The county asks for its Decline in Value Reassessment Application with comparable sales.
We handle it by filling the form, collecting your e-signature, and submitting it to the Assessor.
The county asks for its 2026-2027 Prop 8 (Decline in Value) Request Form with your opinion of value and up to three comparable sales that closed on or before March 31, 2026.
We do the analysis. We pull your parcel, run the comparable-sales review, and hand you a copy-ready page (and an email) with your opinion of value and the three strongest comps.
You finish on the county's quick portal. Santa Clara takes this request through its own online portal. You sign in with your APN and the PIN from your mailed Notification of Assessed Value, complete a short verification, paste in the values we gave you, and submit. About two minutes.
The county asks for its Request for Decline in Value Review (ASRR5, residential properties of two units or fewer) with your opinion of value as of January 1, 2026, your assessed value, and up to three comparable sales that sold no later than March 31, 2026.
We handle it by filling the county's own ASRR5, attaching your comparable-sales worksheet, collecting your e-signature, and emailing it straight to the Assessor with you copied. Emailing the completed form is printed on the form itself as an accepted way to file.
One thing to expect: Once a property receives a reduction, Santa Cruz reviews it every year at no charge until the Proposition 13 value is restored, so already-reduced parcels do not need to file again. The county may also visit the property as part of its review.
The county asks for its Assessment Review Request (Prop 8) with your parcel number, contact details and property type. The county form has no space for comparable sales, so your evidence travels as an attachment.
We handle it by filling the county's own 2026/2027 form, attaching your comparable-sales worksheet as the supporting evidence, collecting your e-signature, and printing and mailing it First-Class to the Assessor. We close Solano filings November 14 so every letter is postmarked before the county's November 30 deadline.
One thing to expect: Solano's informal review and its formal appeal both close on November 30, so waiting for the informal result leaves no room to appeal afterwards.
The county asks for its 2026 Prop 8 (Decline in Value) Request Form with your opinion of value, your contact details, and up to three comparable sales. Sales recorded after March 31, 2026 cannot be considered.
We handle it by filling the county's own 2026 form, attaching your comparable-sales worksheet, collecting your e-signature, and printing and mailing it to the Assessor for you.
One thing to expect: Sutter asks for requests by August 1 so it can correct values before December 30, but it publishes no hard cut-off and continues to accept them. The county form carries no signature line, so your signature goes on the worksheet we attach. Properties already on a Proposition 8 value are reviewed automatically each year.
The county asks for its Request for Informal Assessor Review (Prop 8, form YC-LD2026) with your opinion of value as of January 1, 2026, your current assessed value and building square footage, and up to three comparable sales that closed before March 31, 2026. Residential property only.
We handle it by filling the county's own 2026-27 form, attaching your comparable-sales worksheet, collecting your e-signature, and emailing it straight to the Assessor with you copied. You do nothing else.
One thing to expect: Yolo County may schedule a brief site visit as part of the review. If they do, the Assessor's office contacts you directly to arrange it.
