Malibu, Calif. ? The summer beach party scene could be coming to an end in Malibu for a brigade of Hollywood B-listers like Sean Stewart, Jonathan Silverman and Nicky Hilton.

And not just because summer is almost over.

Malibu leaders are rolling up the welcome mats at three corporate-financed celebrity party houses that regular beach residents complain have clogged oceanfront streets, created noise problems and caused paparazzi to swarm over the sand.

“We’ve had 26 parties at the house next to us. About half of them have been major, major parties with hundreds of people. It’s almost been like a take over,” said resident Renny Shapiro. “We had to cancel any activities we planned for the summer.”

Shapiro lives on Malibu Beach, next to what is known internationally as the Polaroid Beach House. A few houses the other direction is the LG Beach House. Nearby Carbon Beach has been home this summer to the Silver Spoon Beach House.

The companies rented the mansions from their owners for the summer and are using them to promote products by linking them to hot young celebrities. And the celebs seem more than happy to indulge themselves with food, drink and gifts – and indulge paparazzi by showing off their tans and bikinis on the beach.

But behind the scenes, city officials contend, there is noise, illegally parked cars blocking driveways and fire hydrants and seemingly nonstop action.

One party at the Polaroid house – the one with the models’ pillow fight – is said to have lasted 22 hours. And residents say organizers had to borrow a neighbor’s vacuum to clean up the pillow feathers.

Beach house operators dispute allegations that their parties are a public nuisance. They claim they are following the letter of the law and that residents are exaggerating the nuisance factor.

“I think a lot of the residents on the beach are making themselves so worked up that they’re not looking at the big picture,”said Jessica Meisel, whose marketing company, Fingerprint Communications, runs the Polaroid Beach House. “We never had one police officer come to the house the entire summer.”

Nonetheless, city officials are mapping plans to create a new city ordinance that will limit corporate beach house operations in the future.

Writing the ordinance will be a delicate matter, in large part because many Malibu homes are – as the real estate agents like to say – “an entertainer’s dream,” with ocean views, infinity pools and sprawling grounds. And many full-time residents like to party.

The goal is to regulate corporate parties while still allowing weddings, barbecues, bar mitzvahs and sweet 16 parties.
