Buyers ask me about Mello-Roos every week — usually after their lender pulls the tax bill and they see a line item they didn't expect. In Moorpark Highlands, Camarillo Springs and Mission Oaks, and the Porter Ranch master plan, Mello-Roos special tax assessments can add $2,500 to $6,000 per year to the property tax bill for the next 20 to 40 years. The numbers move home affordability and they move the offer price. I'm Brian Cooper, REALTOR(R) at eXp Realty (DRE# 01434286). This is the plain-English read on what Mello-Roos is, where it shows up in our markets, and how to look up your specific parcel.
Quick Answer
Mello-Roos is the common name for California Community Facilities District (CFD) special tax assessments authorized under the Mello-Roos Community Facilities Act of 1982 (Gov Code 53311 through 53368.3). When a new development needs infrastructure — streets, schools, sewers, fire stations, parks — the developer and the local agency form a CFD. The CFD issues bonds to pay for the infrastructure up front. Property owners inside the CFD pay an annual special tax, collected on the regular county property tax bill, until the bonds are retired. Bond terms are typically 20-40 years.
In Ventura County, the largest CFDs are in Moorpark Highlands (CFD 88-1, 97-1, and successors), Camarillo Springs and Mission Oaks (CFD 91-1 and successors), and parts of newer Camarillo and Oxnard tracts. In Los Angeles County, the Porter Ranch master plan has CFD 7 (and others) covering the newer Toll Brothers and Lennar tracts. Annual special-tax amounts vary by parcel size and tax category. Most homes inside an active CFD pay $2,500 to $6,000 per year in Mello-Roos on top of the regular Prop 13 property tax. The special tax is not deductible federally as property tax.
What is a CFD and why does it exist?
Before Mello-Roos existed, local governments paid for new-development infrastructure through general obligation bonds backed by ad valorem property taxes. Proposition 13 (1978) capped property tax at 1% of assessed value and made it nearly impossible to issue new GO bonds without a 2/3 voter approval of the entire jurisdiction. That meant new developments could not easily finance their own infrastructure.
Senator Henry Mello and Assemblyman Mike Roos co-authored the 1982 Act to solve this. A CFD is a narrowly defined geographic area, often just one subdivision, in which a special tax is imposed with a 2/3 vote of the landowners within the district (or registered voters if there are 12 or more). Because the vote is geographically limited to the area benefiting from the infrastructure, approval is straightforward. The district issues bonds; the special tax pays the bonds; the bonds fund the streets, schools, parks, sewer lines, and fire stations specific to that development.
Practically, this means almost every Ventura County and northwest LA subdivision built since 1985 has some Mello-Roos exposure. Older neighborhoods built before the Act do not. A 1965-vintage Simi Valley home in central Simi has no Mello-Roos. A 1995-vintage Moorpark Highlands home very likely does. Tract age is the first clue.
Term length: 20 to 40 years, then reauthorization
CFD bonds typically have 20- to 40-year amortization. The original CFD-formation resolution specifies the maximum special tax and the duration. When the bonds are paid off, the special tax goes away — unless the CFD has been reauthorized for new infrastructure or the bonds have been refinanced with extended maturity.
Moorpark Highlands CFD 88-1 was formed in the late 1980s. Original bond maturity was roughly 30 years, which puts the natural payoff date in the late 2010s to early 2020s. Some of those bonds have been paid off and the special tax has dropped or disappeared on certain Moorpark parcels. Others have been refinanced or supplemented with new CFD issuances. Each tract is different.
Porter Ranch CFD 7 is newer (early 2000s) with bond maturity into the 2030s and 2040s. Camarillo Springs / Mission Oaks tracts vary by phase: earliest phases (1990s) are closer to payoff; newer phases (2000s+) have 15-25 years remaining.

How to look up your specific parcel's CFD
Three reliable methods to confirm Mello-Roos exposure on a specific property before you write an offer.
- Pull the prior year's actual tax bill from the County Assessor or Treasurer-Tax Collector. The Mello-Roos special tax shows up as a separate line item, usually labeled 'CFD' followed by a number (e.g., 'CFD 88-1 SPECIAL TAX' or 'COMMUNITY FACILITIES'). Add up all CFD-related lines. That is your current annual exposure.
- Request a Notice of Special Tax (Civil Code 1102.6b) from the seller during escrow. Sellers must provide this notice for any property inside a CFD. The notice discloses the maximum special tax, the duration, and the bond purpose.
- Check directly with the local agency that formed the CFD. For Moorpark, the City of Moorpark Finance Department. For Camarillo, the City of Camarillo. For Porter Ranch, Los Angeles County Department of Public Works and the Porter Ranch Quality of Life Foundation. They publish CFD official statements showing exact tax tables and remaining bond maturity.
I run this for every Mello-Roos client before they write an offer. The 30 minutes of research can save $30K in surprise tax exposure over a 10-year hold.
Seller disclosure obligations (Civil Code 1102.6b)
California Civil Code 1102.6b requires sellers of residential property inside a CFD to deliver a Notice of Special Tax to the buyer 'as soon as practicable before transfer of title.' The notice must include the maximum amount of the special tax, the date the obligation terminates, and the purposes for which it is levied. The notice has to be signed by the buyer acknowledging receipt.
Failure to deliver the notice gives the buyer a rescission right under Civil Code 1102.13. The buyer can rescind the sale up to three days after receiving the notice if the failure to disclose happened before transfer. After transfer, the buyer's remedy shifts to damages.
As a listing agent, I order the Notice of Special Tax from the city or county finance office during escrow and include it in the buyer disclosure package along with the Natural Hazard Disclosure, Transfer Disclosure Statement, and Seller Property Questionnaire. Title companies will also pull a current CFD report at the buyer's request.
Tax deductibility: NO under IRC 164
This is the question that catches buyers most often. Mello-Roos is NOT federally deductible as property tax. The IRS draws a distinction: ad valorem real property taxes (taxes based on the assessed value of the property) are deductible under IRC 164(a)(1). Special assessments (taxes for local benefits that increase the value of specific property — sewers, sidewalks, infrastructure for a new subdivision) are NOT deductible under IRC 164(c)(1).
Mello-Roos special taxes are structured as special assessments to finance specific infrastructure that benefits the CFD. They fail the IRC 164(a)(1) test because they are not based on assessed value (they are based on lot size, square footage, or per-unit formulas set by the CFD formation). They meet the special assessment definition. So they're not deductible.
California allows deduction for state-purposes property tax on a similar basis. Mello-Roos is generally not deductible on the California return either.
The practical impact: on a $4,000/year Mello-Roos bill, a homeowner in the 24% federal bracket saves nothing in tax. Compare to a $4,000 deductible property tax, which would have saved approximately $960 in federal tax (subject to SALT cap). That $960 / year over a 20-year hold is $19,200 in real after-tax cost difference.
Resale impact: how Mello-Roos moves home price
Mello-Roos affects resale price two ways. First, buyer affordability: the special tax increases the total monthly housing cost (PITIA, where the second 'A' is assessment). Lenders include Mello-Roos in the DTI calculation. A $5,000 / year Mello-Roos bill is $417 / month, which reduces the loan amount a buyer qualifies for by approximately $70,000-$80,000 at current rates. Buyers with Mello-Roos exposure have less buying power for the same income.
Second, the special tax depresses the comparable value of homes inside a CFD versus identical homes outside one. Comparing a Moorpark Highlands home with $3,500 / year Mello-Roos to an identical floor plan in central Moorpark with no Mello-Roos, market typically discounts the CFD home by roughly the present value of the special tax stream — generally 4-7% of the sale price.
Buyers I represent in CFD areas net this out before writing the offer. I tell sellers to expect appraiser comments referencing the Mello-Roos burden if they are pricing at parity with non-CFD comps. The Notice of Special Tax becomes part of the appraisal package.
When the bonds pay off — and when they reauthorize
Original CFD bond maturity is set in the formation documents. When all bonds are paid off, the special tax stops. The first generation of Moorpark Highlands CFD 88-1 bonds have largely matured, and a subset of original-phase Moorpark Highlands homes have no current Mello-Roos line on the tax bill. That is a genuine value to those specific parcels — and a reason to confirm phase-by-phase before assuming Moorpark Highlands = Mello-Roos.
Reauthorization happens when the CFD board needs to fund additional infrastructure (a new fire station, additional school expansion, a sewer replacement) within the same CFD boundary. New bonds get issued under the existing CFD structure, or a new CFD is layered on top of the old one. The special tax can resume or increase. This is rarer than original-bond maturity but it happens.
Refinancing is more common. A CFD with bonds at 5.5% from 2008 can refinance into 3.5% bonds in a lower-rate environment, reducing the special tax for homeowners. This is good news. The CFD board typically passes the savings through to the special-tax payers. Watch for refinancing announcements in your CFD's annual report.
Frequently Asked Questions
How is Mello-Roos different from regular property tax?
Regular property tax is ad valorem — calculated as 1% of assessed value under Prop 13 plus locally approved overrides. Mello-Roos is a special tax based on a per-unit, per-square-foot, or per-acre formula set when the CFD was formed. Regular property tax is permanent (subject to Prop 13 inflation limits); Mello-Roos has a defined termination date when the bonds are paid off. Regular property tax is federally deductible; Mello-Roos generally is not.
Can I refuse to pay Mello-Roos?
No more than you can refuse to pay property tax. The special tax is collected on the same bill. Non-payment triggers the same tax-delinquency procedures and can ultimately lead to a tax-defaulted property auction. Some CFDs allow prepayment of the remaining special tax obligation (effectively buying out the obligation), but the prepayment amount can be substantial.
Does Mello-Roos go with the property or the owner?
With the property. The special tax runs with the land and transfers to the new owner at sale. The buyer assumes the remaining tax obligation through the CFD's bond maturity. This is why disclosure under Civil Code 1102.6b matters.
Are there areas in Simi Valley with Mello-Roos?
Limited. Most of Simi Valley was built before 1985 and has no Mello-Roos. Big Sky (built 2003+) has CFD exposure on certain phases. Wood Ranch is largely Mello-Roos-free because most of it predates the 1982 Act, with limited exceptions in the newest phases. Always confirm by parcel.
What about Thousand Oaks and Westlake Village?
Largely Mello-Roos-free. Both cities were substantially built out before 1985. The exceptions are a few newer infill projects. Newbury Park has some newer tracts with CFD exposure.
Can the Mello-Roos amount go up over time?
Typically capped by an annual maximum increase set at CFD formation — often 2% per year. The CFD board cannot exceed the maximum special tax adopted in the formation resolution without a new vote. Read the CFD's Rate and Method of Apportionment for your specific cap.
How do I find out who manages my CFD?
The CFD administrator is named on the Notice of Special Tax and on the bond official statements. For Moorpark, it is the City of Moorpark Finance Department. For Camarillo, the City of Camarillo. For Porter Ranch, the LA County Department of Public Works. The administrator handles billing inquiries, prepayment requests, and bond status.
Does Mello-Roos count toward the federal SALT cap?
No, because it is not deductible at all. The $10,000 SALT cap under TCJA applies to deductible state and local taxes. Non-deductible Mello-Roos special assessments don't count for or against the cap because they are not deductible in the first place.
