If you’re buying a home in California, chances are you’ve come across the term Mello-Roos tax. It’s not a neighborhood or a builder’s fee—it’s a special property tax that can significantly affect your monthly housing costs. But what exactly does it mean, how long does it last, and can you avoid it?
In this post, we’ll break down everything you need to know about Mello-Roos districts, including how they work, what they fund, and tips for California homebuyers.
What Is Mello-Roos?
Mello-Roos refers to a special tax authorized by the Mello-Roos Community Facilities Act of 1982. This legislation allows cities, counties, and developers to create what’s called a Community Facilities District (CFD).
The purpose? To fund critical infrastructure and services such as:
-
Public schools
-
Parks and recreation areas
-
Roads and sidewalks
-
Water and sewer systems
-
Police and fire protection
Unlike standard property taxes in California (limited by Proposition 13), Mello-Roos taxes are not capped and can be adjusted to meet the financial needs of the district.

Why Was Mello-Roos Created?
The Mello-Roos Act was introduced after Proposition 13, which restricted how much property taxes could increase each year. While Prop 13 gave homeowners protection from skyrocketing taxes, it left local governments struggling to fund new schools, roads, and public safety services.
Mello-Roos solved this by creating voter-approved special tax districts in specific neighborhoods. Instead of raising taxes across an entire city, only the homeowners who benefit from the improvements pay.
For example, if a new community is built on undeveloped land, the city may not have funds to add schools or sewer systems. Through Mello-Roos, developers finance these projects, and homeowners repay the costs over time via annual tax assessments.
How Much Is the Mello-Roos Tax?
There’s no flat rate—Mello-Roos varies depending on the CFD. On average, it ranges from 0.1% to 1.5% of a home’s value annually. In some cases, it may also be based on square footage, lot size, or even the number of bedrooms.
💡 Pro Tip: Since Mello-Roos is in addition to regular property taxes, always check the total tax bill before purchasing.

What Does Mello-Roos Fund?
Mello-Roos taxes typically pay for:
-
New schools to serve growing populations
-
Community parks and green spaces
-
Streets, sidewalks, and lighting
-
Water and sewer infrastructure
-
Police and fire services
These improvements directly enhance community livability and can even boost long-term property values.
How Long Does Mello-Roos Last?
Mello-Roos doesn’t last forever. Most bonds are structured for 20 to 40 years. Once the bond is fully repaid, the tax expires.
In some districts, homeowners can pay off the balance early in a lump sum, but rules vary.
Can You Avoid Mello-Roos?
Not every California home has Mello-Roos. Generally:
-
Older neighborhoods (built before the 1980s) don’t carry these taxes, since their infrastructure was already funded.
-
Newer developments almost always have them, especially in areas with new schools, parks, or upgraded roads.
If you want to avoid Mello-Roos, focus on established communities. But if modern amenities are a priority, you’ll likely encounter these taxes.
