After months of unruly parties, speeding cars, and unfamiliar guests frequenting their typically quiet neighborhood, residents who live near the home on Valley Vista Boulevard in Sherman Oaks where a home-invasion robbery and double shooting occurred early Wednesday were already primed for something violent to happen.

Los Angeles police are still searching for the two men they believe robbed several people at the location, which is listed as a short-term rental on the website Airbnb. Officials said the two suspects, armed with handguns, entered the rear door of the home at 15373 Valley Vista Boulevard around 6 a.m., then demanded money from the people inside. Before they fled with an unknown amount of cash, they shot and wounded two other men, one who drove himself to a nearby hospital.

Mitchell Moadeb has lived across the street with his family for 14 years in a neighborhood, where homes typically sell for around $1.5 million to $2 million. Moadeb’s own home was once owned by Liberace.

Moadeb said Wednesday there’s been constant activity at the house across the street for months. Like other neighbors, he described at least one huge party thrown there recently.

There were “cars peeling out, all up and down the streets, there were bottles of alcohol and trash,” he said. He estimated about 400 to 500 people showed up, mostly teenagers.

He said the new owners of the home recently tore down the previous house, and built what stands there today.

“This house has been a disaster for our neighborhood since it was built,” said Dick Taylor, who has lived in the home kitty-corner to the residence for 33 years. Taylor witnessed the massive party, too — he and his wife could see some of what was going on from their bedroom window.

He said he saw a bouncer guarding the front door. Groups of 10 to 15 either waiting to get in the party or who just left were milling around the neighborhood. Taylor said his neighbors were worried something violent would eventually happen at the home. “Last night it came true,” he said.

Officials at the LAPD’s West Valley Division said Thursday no arrests have been made.

“This house has been a disaster for our neighborhood since it was built.”

Before this year, Los Angeles residents had few resources when faced with neighbors throwing raucous parties. But houses like the one on Valley Vista Boulevard that host large events bringing huge groups of guests to once quiet suburban streets were the target of a recent city ordinance proposed by Councilman David Ryu.

Last week, the city council passed what Councilman David Ryu called the Party House Ordinance to crack down on properties like the one on Valley Vista Boulevard.

The ordinance would allow the city to levy increasingly heavy fines against the owners of homes where loud, unruly parties are thrown. The fines range from $100 for the first violation of the ordinance up to $8,000 for a sixth violation and every violation after that.

The Valley Vista home is just outside of Ryu’s district, but the issue of party homes has affected many of the neighborhoods the councilman represents in the Hollywood Hills.

“All-night parties with hundreds of guests crowding narrow streets in the hillsides block the right-of-way for emergency vehicles and consume the time and resources of our police officers who, at present, have no recourse to actually solve the problem,” Ryu said in October when he introduced the ordinance.

The new law is awaiting Mayor Eric Garcetti’s signature to take effect.

Frank Mateljan, a spokesman for the City Attorney’s Office, said the ordinance specifically targets the owners of party houses. For unruly guests at these parties, the city can also enforce municipal code violations, including noise, parking, trespassing, drinking in public and servicing alcohol without a license.

“Our office has been able to resolve many situations informally,” Mateljan said in a statement.

However, the fact that the owner of the home does not appear to live at the location has made solving the issue more difficult for neighbors. The home was listed on Airbnb by a user named “Victor,” who described the location a “Lovely New home in Los Angeles!!!” for groups of eight to stay. On Thursday, the house was listed at $1,000 per night. A nearly identical listing on the website by Victor for the same home advertised the property as being worth $3 million.

According to property records, Kanagaratnam Sivalingam, a doctor who lives in Lancaster and has a medical office there, bought the home in October 2017 for $1.3 million. A secretary at Sivalingam’s office declined comment, but was taking down the names of reporters from several media outlets for statement to be released later.

Neighbors said they’ve never seen the doctor at the home. After each party, they’ve seen cleaning crews who go in to tidy up. Taylor said residents were planning to contact the doctor to complain about the events in their neighborhood.

An Airbnb spokeswoman said the company was investigating the incident.

The company does not appear to have policies specifically dealing with listings where crimes have occured. Airbnb’s website lists policies related to disclosures of user information to requests from law enforcement. And it also states that requests from users in the case of emergencies should be directed to police, or to the Airbnb Customer Experience team.

But the company also set up a “Neighbor Tool” for nearby residents to complain about homes listed on Airbnb that disturb the peace in the neighborhood. Anyone wishing to make a complaint can go to www.Airbnb.com/neighbors to fill out a form.

“The safety of our community is our priority,” said spokeswoman Molly Weedn in a statement. “Hosting is a big responsibility and those who fail to meet our standards and expectations will be subject to suspension or removal.”
