California requires sellers to disclose Mello-Roos special taxes to buyers. This guide explains the seller's disclosure obligations in general terms and how buyers should verify the special-tax line themselves.

Direct AnswerCalifornia law generally requires a seller in a Mello-Roos district to provide the buyer a Notice of Special Tax disclosing the CFD special tax. Sellers should disclose the current amount accurately; buyers should still independently verify the special-tax line on the parcel's LA County tax bill or with the CFD administrator.

What Mello-Roos actually is

Mello-Roos is the nickname for the California Community Facilities Act of 1982 (named for legislators Henry Mello and Mike Roos). It lets a local agency form a Community Facilities District (CFD) and levy a special tax on parcels inside that district to fund infrastructure and sometimes ongoing services — roads, sewers, parks, schools, and other facilities tied to new development.

The special tax is separate from your ~1% Prop 13 base property tax. It appears as its own line (or several lines) on the Los Angeles County secured property-tax bill. Unlike ad valorem tax, a Mello-Roos special tax is generally calculated by a formula in the formation documents — often based on lot size, building square footage, or a flat per-unit amount — not on your home's assessed value.

  • It is a lien that runs with the land, not with the owner.
  • Most CFD bonds are repaid over a fixed term (commonly 20–40 years); that bond-related portion can roll off when the bonds are retired, while services CFDs may be ongoing.
  • The exact amount and annual escalator are set per district in the formation documents and recorded Notice of Special Tax Lien.

The seller's disclosure obligation

Under the Mello-Roos Community Facilities Act, a seller of a home within a CFD is generally required to give the buyer a Notice of Special Tax that identifies the special tax and its key terms. This is in addition to the standard Transfer Disclosure Statement and other required California disclosures.

Sellers should not guess at the amount. Pull the current LA County tax bill and disclose the figure shown, and point the buyer to the CFD administrator for confirmation.

What buyers should still verify

Even with a disclosure in hand, a buyer should independently confirm the current special tax, the escalator, and the remaining bond term directly with the CFD administrator.

How to verify the exact Mello-Roos on a specific parcel

Because amounts vary by tract and must be confirmed per parcel, treat any range you see online as a starting point only. To get the real number:

  1. Pull the parcel's Los Angeles County secured property-tax bill and read the direct/special-assessment lines — Mello-Roos appears here, often with a phone number for the CFD administrator.
  2. Call the listed CFD administrator to confirm the current annual amount, the escalator (how much it can rise each year), and the expected payoff or expiration year for bond-related charges.
  3. Review the seller's required disclosures, including the Notice of Special Tax and any recorded Notice of Special Tax Lien.
  4. Ask whether the charge is bond-repayment (finite term) or a services special tax (potentially ongoing).

Confirm the exact special-tax line on the parcel's tax bill or with the CFD administrator before you rely on any figure.

Why SCV Mello-Roos runs materially higher than the neighboring Ventura-area market

Most homes that carry Mello-Roos in our region sit in the master-planned tracts of the Santa Clarita Valley, where large CFDs funded the roads, schools, and infrastructure that opened up new development. As a practical matter, SCV special taxes tend to run materially higher than what buyers see in much of the neighboring Ventura-area market, where fewer parcels sit inside large, recently formed CFDs.

That is a generalization about how common and how large these districts are — not a quote for any one home. The only number that matters is the special-tax line on the specific parcel you are buying.

Do not rely on a neighbor's figure. Mello-Roos varies by tract, by phase, and sometimes lot-by-lot within the same community. Two homes on the same street can carry different special taxes. Always verify the exact amount on the parcel's own tax bill.

Why accurate disclosure protects sellers too

Understating or omitting Mello-Roos can create liability and derail a sale at closing. Accurate, well-documented disclosure builds buyer confidence and keeps the transaction clean.

Frequently Asked Questions

Is Mello-Roos the same as property tax?

No. Your base property tax is the ~1% Prop 13 ad valorem rate on assessed value. Mello-Roos is a separate special tax levied by a Community Facilities District and shown as its own line on the Los Angeles County tax bill. It is generally set by a formula, not by your home's value. This is general information, not tax advice.

How much is Mello-Roos in this area?

It varies by tract, by phase, and sometimes lot-by-lot — and SCV special taxes tend to run materially higher than much of the neighboring Ventura-area market. We do not quote a fixed dollar figure here. Confirm the exact special-tax line on the parcel's own LA County tax bill or with the CFD administrator.

Does Mello-Roos ever go away?

Bond-repayment special taxes are usually levied for a fixed term (commonly 20–40 years) and the bond-related portion can roll off when the bonds are retired. Services-based special taxes can be ongoing. Confirm the term for the specific district.

Can Mello-Roos increase each year?

Many districts include an annual escalator capped by the formation documents. The cap and method vary by CFD, so confirm the escalator for the specific district with the administrator.

Is Mello-Roos tax-deductible?

Whether any portion is deductible depends on your facts and current IRS rules; special assessments for local benefits often are not deductible. This is general information, not tax advice — confirm with a CPA.

Who do I call to verify the amount?

The CFD administrator listed on the parcel's Los Angeles County property-tax bill. They can confirm the current annual amount, the escalator, and the expected payoff year for bond charges.
