Mello-Roos / CFD

A California-specific special property tax assessment funding new infrastructure (schools, parks, roads) in newer-build communities. Adds 0.5–2% on top of the base ~1% property tax for 20–40 years. Common in Irvine, Folsom, Eastvale, and most Bay Area edge-city developments.

Last updated

Mello-Roos (formally the Mello-Roos Community Facilities Act of 1982) is a California-specific special property tax that lets new developments fund their own infrastructure — schools, parks, libraries, fire stations, roads — by issuing bonds repaid by an extra annual tax on every home in a defined Community Facilities District (CFD). For families considering a home in a newer California suburb, Mello-Roos is unavoidable in most of the developments with the strongest schools, and worth understanding before you bid.

What Mello-Roos actually pays for

When California passed Proposition 13 in 1978, it capped local governments' ability to fund new schools and infrastructure through traditional property taxes. The Mello-Roos Act in 1982 created the workaround: developers and local agencies could form a CFD, issue bonds to build the infrastructure, and have the homebuyers in that district repay the bonds via a special tax on top of the base 1% property tax. In practice, this means: in a newer-build California suburb, your Mello-Roos is probably paying for the elementary school your kids will attend, the middle school five years from now, the community park, and possibly the fire station. The tax is itemized on your annual property tax bill alongside the base assessment.

How much it costs

Mello-Roos rates are not standardized — every CFD sets its own. Typical ranges in 2026: Irvine, Aliso Viejo, Ladera Ranch (OC): 0.7%–1.2% additional on assessed value, often $4,000–$10,000/year on a $1M home. Folsom, El Dorado Hills, Roseville (Sacramento area): 0.5%–1.0%, often $3,000–$7,000/year. Eastvale, Corona, Menifee (Inland Empire): 0.8%–1.5%, often $4,000–$9,000/year. Most newer Bay Area edge cities (Tracy, Mountain House, Brentwood): 0.6%–1.2%. Older Bay Area established cities (most of the Peninsula, San Francisco itself, Berkeley, Oakland) typically have NO Mello-Roos because they were fully built out before 1982. The presence of Mello-Roos almost always indicates a newer-build community.

When Mello-Roos ends — and when it doesn't

Most Mello-Roos bonds have a defined repayment term, usually 25 to 40 years from issuance. Once the bonds are paid off, the special tax ends. But there are two important wrinkles: The term starts at bond issuance, not at your purchase. If you buy a 2008-built home in 2026, you may have only 7–22 years left of Mello-Roos — far less than the original 25–40-year term. Always ask the seller (or check the county recorder) for the original CFD formation documents to see the actual end date. Reissuance and re-bonding. Some CFDs issue new bonds for additional infrastructure (a new middle school, a park expansion) before the original bonds are paid off. This effectively extends the Mello-Roos period. Communities that are still actively building amenities are more likely to do this.

Mello-Roos and the school question

Mello-Roos is the closest thing California has to a 'pay for the school you're getting' tax. The trade-off is direct: you're paying $4,000–$10,000/year on top of your property tax, and a meaningful chunk of that funds the elementary, middle, or high school your kids will attend. This matters for the family math because it changes how you should compare similar-priced homes: A $1.4M home in a Mello-Roos district with a $7,000/year MR fee is the affordability-equivalent of a $1.5M home with no MR. If the MR-district home zones to a 9/10 elementary, and the comparable non-MR home zones to a 6/10 elementary, the $7,000/year is buying you something — possibly worth it. If both homes zone to similar-quality schools, the MR is just dead weight on your budget. This is the case in some older non-MR Bay Area suburbs that historically funded their schools through other means.

How to find out a property's Mello-Roos before bidding

Mello-Roos must be disclosed by the seller in California — it's a required item on the Transfer Disclosure Statement and the standard residential purchase agreement. But you don't have to wait for escrow to find out. Three ways to check before you write an offer: 1. The listing itself often discloses MR in the property tax line ('total estimated taxes including special assessments: $14,500/yr on a $1.2M home' is the giveaway — the base tax would be ~$12,000, so the extra $2,500 is MR). 2. The county tax assessor's website. Search the property's APN, look at the most recent tax bill — Mello-Roos appears as a separately-itemized line. 3. Ask your buyer's agent for a Mello-Roos summary report from the county. Free, takes a day. The report shows the CFD name, current rate, and bond payoff date.
Frequently asked

Mello-Roos / CFD questions families ask

Is Mello-Roos tax-deductible like regular property tax?

Federally, the answer is mostly no. Only the portion of Mello-Roos that funds general government services (rare) is deductible — the portion funding bond repayment (most of it) is not deductible because it's considered a benefit assessment, not a tax. In practice, treat Mello-Roos as fully non-deductible for affordability planning.

Can Mello-Roos rates go up?

Yes, modestly. Most CFDs allow annual increases of 2% per year, similar to Prop 13's base assessment cap. Some CFDs allow more, especially newer ones. Always check the CFD formation document for the exact escalator clause.

Why don't established Bay Area cities like Palo Alto or Berkeley have Mello-Roos?

Mello-Roos was created in 1982 specifically to fund infrastructure in NEW developments. Cities fully built out before 1982 funded their schools and infrastructure through the pre-Prop-13 property tax system, which had higher base rates. Most Peninsula cities and core East Bay cities fall into this category — they pay roughly 1.0–1.2% base property tax with no MR. Newer edge cities (Tracy, Brentwood, Mountain House) pay 1.0% base + MR.

Should I avoid Mello-Roos communities entirely?

No. Many of California's strongest family-friendly suburbs (Irvine for Asian-American families looking at Northwood/Woodbridge; Folsom for Sacramento-region tech families; San Ramon and Pleasanton for Bay Area commuters) are heavily MR-funded and have excellent schools. The right framing is: include MR in your monthly affordability math, then compare on total cost, not headline price.
