Virginia has a 4 p.m. Burn Law, which is a ban/restriction on open air burning before 4 in the afternoon if your fire is within 300 feet of the woods or dry grass which can carry the fire to the woods. You are allowed to burn between 4 p.m and midnight as long as you take proper care and precaution and attend your fire at all times. This law is in effect yearly from February 15th and runs through April 30th. This law can be enacted by both local and state authorities should the conditions call for it at any time during the year.
