Mello-Roos

Definition and meaning of Mello-Roos in real estate.

A Mello-Roos is a special tax assessment district in California created to finance public infrastructure and services within new housing developments.

In more detail

Property owners in these districts pay a special tax, usually on their annual property tax bill, to fund improvements like roads, schools, parks, and water systems. This tax is named after the California legislators who drafted the authorizing act. When developers build new communities, local governments use Mello-Roos bonds to pay for the initial infrastructure, and the tax is passed along to the homeowners to repay those bonds.

The tax is typically paid monthly or annually alongside standard property taxes and can remain in place for 20 to 40 years. Buyers should be aware of these assessments because they increase the total monthly housing cost and affect borrowing capacity.
