    IMPORTANT NOTICECheck with your local fire district before starting your do-it-yourself, residential or commercial project. The local fire district has individual authority to enforce fire code standards beyond the county's requirements. Coordinating and cooperating with your local fire district early in the process may prevent costly alterations to your do-it-yourself, residential or commercial project and ensure compliance with all applicable health and safety standards.
