Federal, state, and local regulations apply to wood-burning activities, whether it is for heating a home or business, or for outdoor fires. Which regulations apply depend on the setting, the category of equipment used to burn the wood and whether the new wood heaters are EPA-certified. Federal regulations require that newly manufactured and sold wood heaters meet air quality performance standards. State rules apply to some wood heaters and fire safety. Local ordinances can be more restrictive than the state rules and may address nuisance smoke issues and when the appliance was manufactured.
