Mello Roos

Mello-Roos is a tax named after two California legislators who found a way around the landmark, tax-limiting Proposition 13.

The tax allowed local governments to generate revenue to pay for projects such as schools, roads and parks in new neighborhoods.

Typically, housing developers create Mello-Roos districts, which can then issue debt and collect taxes. The tax amounts vary wildly from district to district and even house to house.

One inewsource investigation uncovered some homeowners had been incorrectly taxed and overpaid by hundreds or thousands of dollars in Mello-Roos property taxes.
