For residential land clearing, a burn must be at least how many feet from any occupied building?

• A. 100 feet
• B. 200 feet
• C. 300 feet
• D. 500 feet

Answer: (C)

Maintaining a safe clearance from structures during a burn is essential to prevent ignition from embers, radiant heat, or smoke. The standard minimum distance for residential land clearing is 300 feet. This buffer provides enough space for crews to monitor the burn, use suppression tools, and respond to embers that may travel on the wind. It accounts for typical spotting distances under moderate wind and fuel conditions, helping protect occupied buildings like homes and outbuildings from ignition hazards. While wind, fuel load, and topography can influence how a fire behaves and may require adjustments, the stated minimum is 300 feet. Smaller distances increase the risk of fire spreading to structures, whereas the 300-foot requirement offers a practical safety margin.
