Aerial of a gated master-planned neighborhood at dusk — Mello-Roos explained

Mello-Roos surprises a lot of buyers. This infographic shows exactly how a CFD special assessment stacks on top of your base 1% property tax.

Direct AnswerMello-Roos is a special assessment added on top of the base ~1% property tax — it does not replace it. In CFD tracts (common in Moorpark, Camarillo, and Porter Ranch), it raises your effective rate and monthly payment.

What this shows

Every California home pays a base property tax of about 1% of assessed value (plus small voter-approved add-ons). In newer master-planned tracts, a Mello-Roos Community Facilities District (CFD) levies a separate special assessment on top of that base to repay bonds for streets, schools, parks, and infrastructure.

The key idea the chart makes visible: Mello-Roos does not replace your base tax — it stacks on top of it. Two identical homes can have very different total tax bills depending on whether one sits inside a CFD. That difference directly affects your monthly payment and how much home you can afford.

Why it matters block by block

Mello-Roos is parcel-specific. A home in Moorpark, Camarillo, or Porter Ranch may carry a meaningful CFD assessment while a neighboring older tract has none. Always check the special assessment before you fall in love with a payment estimate.
