Bond funds may only be used for capital projects, specifically the construction, improvement, and related costs of capital projects described in the measure. California law is explicit about what bond proceeds cannot be used for. They may not be spent on employee salaries or benefits, day-to-day operating expenses, routine maintenance, administrative costs, or any purpose not described in the voter-approved measure. Every dollar raised through the bond must go directly toward building capital projects as authorized by voters, nothing else.
