The quirky residence, located in the upscale area of Hillsborough, was built in 1976 and was inspired by the American cartoon.
However, not everyone is a fan.
Locals have called it a "public nuisance" and alleged that "landscape modifications to the home were conducted without planning approvals and building permits".
The current owner, Florence Fang, a former publisher of the San Francisco Examiner, reportedly began renovations on the property in 2017. There are now 15-foot dinosaurs, a giraffe, mastodon, and brightly-coloured mushrooms grazing on the lawn.
According to the suit, she was asked multiple times to halt the works, with officials calling it a “highly visible eyesore and are out of keeping with the community standards.”
Assistant City Attorney Mark Hudak told Fox 2: “We don't like it when people build things first, and then come in and demand or ask for permission later. That's not fair to everyone else who goes through the process.”
In a statement to Associated Press, Ms Fang's grandson Sean Fang said the dinosaurs were beautiful, adding: "They make everyone smile and should stay."
