Yabba dabba don’t — be so tacky!

The wealthy owner of a “Flintstones”-style home in California is being sued by her neighbors, who say the sprawling abode is a hideous nuisance.

Residents living near the cavelike $3 million Bay Area pad — which was inspired by the cartoon — say they aren’t having “a gay old time” because new additions to the property have made it extra-ugly, according to a lawsuit, cited by the San Francisco Chronicle.

“[It] creates a highly visible eyesore and is out of keeping with community standards,” the suit claims, according to the Chronicle.

The abode, in the affluent town of Hillsborough, is owned by businesswoman and former newspaper publisher Florence Fang — who neighbors say outfitted the property with several tacky renovations, such as metal dinosaurs and a sign that declares, “Yabba Dabba Doo.”

Those property changes created “safety hazards that required immediate correction to protect visitors to the property,” the lawsuit notes, according to the paper.

Fang has already received three stop orders from the Hillsborough Building Department in past years and has been fined for her “landscaping” additions, according to the San Mateo Daily Journal.

She didn’t return requests for comment. But her grandson, Sean Fang, said in a statement that she “will fight to save the Flintstone House.”

“I think the dinosaurs are beautiful,” he said. “They make everyone smile and should stay.”

The home was designed in the 1970s by architect William Nicholson by spraying concrete onto a mesh frame.
