Mello-Roos is one of the most misunderstood — and underestimated — costs in California new construction. It adds hundreds of dollars per month to housing costs in newer communities. Here's what it is, how it works, and how to evaluate whether a community's CFD is worth it.
Quick Answer
Mello-Roos (formally, Community Facilities District or CFD assessments) are special taxes levied on newer California developments to fund public infrastructure — schools, roads, parks, fire stations, and utilities. They're separate from property taxes and HOA fees. They run $100–$600+/month depending on the community and are disclosed in the California Public Report every new construction buyer must receive. They are not negotiable and not avoidable — but they can be evaluated and compared across communities.
Why Mello-Roos Exists
California's Mello-Roos Community Facilities Act of 1982 created a mechanism for developers to fund public infrastructure in new communities without impacting general tax revenue. Instead of the general public funding a new fire station in a new subdivision, the residents of that subdivision pay for it via a CFD assessment levied on their properties.
This is why you often see Mello-Roos in newer master-planned communities and not in established neighborhoods built decades ago.
What Mello-Roos Funds (and What It Doesn't)
CFDs typically fund: Roads, water/sewer infrastructure, schools, parks, fire stations, police facilities, and sometimes maintenance of community facilities.
CFDs do NOT fund: HOA maintenance (that's covered by your HOA), upgrades you choose (design center), or builder profit.
How Much Does It Cost?
Mello-Roos assessments vary by community and district. Ranges in Southern California:
- Light assessments: $100–$200/month (some Inland Empire communities)
- Moderate assessments: $200–$350/month (common in Orange County and newer IE cities)
- Heavy assessments: $400–$600+/month (newer master-planned communities with comprehensive infrastructure)
The exact amount is in the CFD documents, available from the sales rep and the county.
How Long Does Mello-Roos Last?
CFDs typically run 25–40 years from formation. Some expire; some extend or have new assessments layered on. Check:
- When the CFD was formed
- How many years remain
- Whether the assessment adjusts annually (many increase by up to 2% per year)
How to Find Mello-Roos Information Before Buying
- Ask the sales rep for the CFD schedule and annual assessment amount
- Request the Public Report — California requires builders to provide this to all buyers. It discloses all assessments.
- Check the county assessor — you can look up Mello-Roos by APN (Assessor Parcel Number)
- Review the Closing Disclosure — Mello-Roos appears as a property tax line item
Evaluating Whether the Mello-Roos Is "Worth It"
Mello-Roos isn't inherently good or bad — it's a component of the community's real monthly cost. To evaluate:
- Add it to HOA + mortgage + property taxes to get the true all-in payment
- Compare to resale homes in the same area (resale in older neighborhoods often has no Mello-Roos)
- Check what the Mello-Roos funds — school quality in a CFD-funded district can be excellent

Frequently Asked Questions
Q: Is Mello-Roos the same as HOA?
A: No. HOA covers community maintenance and amenities; Mello-Roos covers public infrastructure. They're separate charges.
Q: Can I deduct Mello-Roos on my taxes?
A: Partially. The portion that funds specific government services (not school facilities) may be deductible. Consult your tax advisor.
Q: Does Mello-Roos transfer to the next buyer if I sell?
A: Yes. It's tied to the property, not the owner. Resale buyers in a CFD district pay the assessment.
Q: Can I pay off Mello-Roos early?
A: Sometimes. Some CFDs allow payoff of the bond at a lump sum. Ask the district administrator.
Q: Do resale homes have Mello-Roos?
A: They can — if the resale home is in an active CFD district. Many older resale homes are not in CFD districts.
