Mello-Roos is a special tax assessment levied on property owners within designated community facilities districts (CFDs) in California. Established under the Mello-Roos Community Facilities Act of 1982, the tax was created to help local governments finance public infrastructure and services in developing communities. Revenue generated through Mello-Roos assessments is commonly used to fund projects such as roads, schools, parks, utilities, public safety facilities, and other community improvements that support new residential and commercial development.
Unlike traditional property taxes, which are generally based on a property’s assessed value, Mello-Roos taxes are typically calculated using factors such as lot size, square footage, property type, or the specific benefits received by the property. These assessments are often associated with newer developments and may remain in place for several decades until the bonds issued to finance the improvements are repaid. Because Mello-Roos obligations can significantly affect a property’s overall carrying costs, prospective buyers are encouraged to review the terms and duration of any applicable assessments before purchasing real estate within a community facilities district.
