Students of Quinnipiac University in Hamden who choose to live off campus must at least live with one roommate, their landlord.
The town's Planning and Zoning Commission unanimously approved the measure on Tuesday night.
The ordinance focuses on forcing landlords to live with their tenants for the majority of the year and is designed to get a handle on late-night partying and noise.
Homeowners in the area said the parties have taken a toll on their day-to-day lives.
"This has been a long time that we've had to wait for this," said Cindy Civetello of Hamden. "Years that we've had to go through rowdy parties because of absentee landlords."
Those who pushed for the controversial proposal said it's they only way they felt they could protect their quality of life.
Some students, however, said they feel they're being punished for the actions of a few.
"I feel like the town of Hamden paints a very negative picture but, it's really just a small percentage of kids who are the ones who are acting up and misbehaving," said Steve Albano, a Quinnipiac student.
The commission approved the new regulations, which will force landlords who apply for new student housing permits, to live with their tenants for at least 10 months a year.
Officials said the goal is to cut down on student renters and absentee landlords.
"Not everyone's doing it," said Ethan Savluk, a Quinnipiac student. "It's a certain group of people and the people that are doing bad things are the ones getting the most attention for it."
The ordinance took effect already, according to officials.
It will not affect landlords who are currently renting to students, only new permits going forward.
In the meantime, some landlords have already filed lawsuits and more are expected.
