Mass General Law Chapter 48, Section 13 prohibits open air burning without permission. Chimineas and fire pits are considered open burning and as such require a permit. Due to the proximity of structures and concern over fire spread, in Watertown, the fire department does not issue burning permits. If you use a chiminea/fire pit on your property and the Watertown Fire Department responds, the fire will be extinguished and the person operating the chiminea/fire pit would be subject to a fine of up to $500.00.
