Your assessment should reflect the market.

A building's market can change while individual assessments stay high. We check your unit's assessment and tell you whether there is a case for a reduction.

What an appeal could save

Average potential first-year savings, after our service fee $3,600

An estimate, not a promise. Average for the 11 shortlisted homes flagged in our 2026 campaign review, rounded down, after our standard service fee and before county costs. Some estimates use county price indications or preliminary assumptions. Existing reassessments must be checked. Your unit's savings can differ.

From sign-up to decision

01

Sign up online.

Your building is already filled in. Add your unit, confirm your property, and sign the California agreement and authorization online by Tuesday, November 24.

02

Review your assessment.

We review your unit's assessment and the available evidence to determine whether an appeal makes sense.

03

File with Los Angeles.

If there is a case, we prepare and file your application with the Los Angeles Assessment Appeals Board by November 30, 2026, and advance the filing fee.

04

Build the case for your unit.

We gather the property records and market evidence needed to support a lower assessed value.

05

Negotiate with the Los Angeles County Assessor.

We present the case to the assessor's office and work toward a reduction before a hearing.

06

Represent you at the hearing.

If a hearing is needed, we present your evidence to the Assessment Appeals Board or hearing officer and follow through on the decision.

You sign up. We handle the appeal.

What you pay, and when

  1. Nothing now, and nothing if we don't win.
  2. When you sign up, save a card or US bank account. Autopay earns a credit of 2% of our fee — for every $100 we charge, you pay $98.
  3. If we win a lower assessed value, your property tax falls with it.
  4. Then we charge 35% of the tax savings for the year, plus county fees we advanced at cost. Our rate falls to 30% when your combined assessed value exceeds $5,000,000. Nothing on file? We email the bill, due in 30 days.

Questions

What happens after this year's appeal?
Free assessment monitoring continues every year until you cancel; you don't need to sign up again. We pursue another appeal when we determine there's a case worth filing. We notify you first and arrange any new owner authorization or signature your county requires before filing.
Can I appeal myself?
Yes. You can request a free informal review directly from the Los Angeles County Assessor or file your own application with the Los Angeles Assessment Appeals Board. Castellan is a private service, independent of government.
What do I need to sign up?
Your unit number, your contact information, and the authority to sign for the owner. We look up the property record. If we need documents for the case, we will ask for them.
My unit is in an LLC or trust
Sign as the person authorized to act for that owner and enter the ownership details in the signup form.
Will every unit get a reduction?
No. Each unit has its own assessment and evidence. A low existing assessment or resale restrictions can change whether an appeal is worthwhile. We review the unit before filing.
Does a reduction last forever?
A California decline-in-value reduction is reviewed annually. Future assessed values can rise again, up to the Proposition 13 protected value. The agreement explains how future-year reviews and fees work.
Does this change HOA dues?
No. This service concerns property tax assessments, not HOA dues or fixed charges on your tax bill.
