What Is Mello-Roos?
Mello-Roos is a special tax authorized by California's Community Facilities District
Act of 1982. When a developer builds a new master-planned community like Serrano, they
can form a Community Facilities District and sell bonds to the public to fund the
infrastructure that makes the neighborhood possible: graded roads, water and sewer
lines, parks, school sites, and utilities.
The bonds are repaid over time by homeowners within the district through an annual
special tax billed on their property tax statement. You don't pay the developer —
you pay El Dorado County. When you buy in Serrano, you inherit this obligation as
a condition of ownership.
What Does It Fund?
CFD bonds pay for the public infrastructure built at the time of development —
the things that had to exist before anyone could move in. In Serrano and El Dorado
Hills, this typically includes graded and paved roads, curbs, gutters, sidewalks,
storm drainage, water and sewer trunk lines, parks, open space improvements, and
sometimes school facility contributions.
Without Mello-Roos financing, the developer would have charged all of those
infrastructure costs upfront in the purchase price — or not built at all.
How Much Does It Add?
In El Dorado Hills and Serrano, Mello-Roos assessments typically add between
$2,000 and $6,000+ per year on top of
the base 1.1% county property tax. The exact amount depends on which CFD your
specific parcel falls within — some Serrano addresses carry one district, others
carry two or three layered obligations.
On a $900,000 home, the base property tax is roughly $9,900 per year. Add a
$4,000 Mello-Roos assessment and your annual bill climbs to $13,900 — nearly
$1,160 per month in taxes alone.
How Long Does It Last?
CFD bonds are issued for a fixed term, typically 25–40 years,
and the special tax obligation ends when the bonds are paid off. Older Serrano
sub-communities may be closer to their pay-off date; newer phases can have
20+ years remaining.
California law requires sellers to disclose Mello-Roos before closing and provide
a Notice of Special Tax — including the district name, current annual amount, and
the bond maturation schedule.
