Bubba Murphy Lake told WSB-TV that someone passing the house in Berkeley Lake with their children thought the display looked so realistic that they called 911.
Fire officials responded and told him to take the display down at least temporarily. The display also had a ladder toppled over in the front yard.
Murphy says homeowners in his Cobb County neighborhood go all out with their Christmas displays every year.
Berkeley Lake is about 22 miles northeast of downtown Atlanta.
