The San Benito GHAD is financed through the collection of supplemental tax assessments from homeowners within the GHAD’s boundary. Revenue is typically split between an ongoing operations/maintenance and the accumulation of a reserve for less frequent major repair items.

Each year, an annual assessment and budget is considered and adopted by the San Benito GHAD Board of Directors.
