City planning commissioners expressed concern that the later hours would increase the volume of nighttime noise from the restaurant, according city spokeswoman Tara Finnigan.
"We were pleased that the commission listened to the arguments that we had," said Donald McCalla, who has lived in his Linda Isle home for more than two decades.
His home faces the restaurant, about 200 feet away across the water, and takes the brunt of the noise caused by the late-night crowd that fills the patio past the allowed hours, he said.
"The big issue is noise," McCalla said. "Our argument to the owner is, 'Look, if you will attenuate that [patio] as well as your existing building, the problem will cease. You will no longer hear from us.' That building is probably one of the most well-attenuated buildings in the city. We do not hear what goes on inside that building."
Three homes on Linda Isle face 3-Thirty-3, with the other affected homes facing Bayside Drive currently not occupied, said Linda Isle Homeowner's Assn. President Donna Viana, who lives on the island down the street from those homes.
"You're going to have some people outside making noise, yes, that's going to happen," Viana said. "But this is inside and those windows remain open past the time they are supposed to be closed and directly face the bedrooms of the people on the island."
When plans for the patio were approved in 2007, Reuter, the city and Linda Isle residents agreed to a compromise, which stated that the patio had to be built with sound attenuation devices and time constraints. The patio was opened early 2010.
"A deal is a deal," Viana said.
McCalla said that he reported almost 20 noise disturbances after 9:30 p.m. caused by 3-Thirty-3 patrons from March 2010 to September 2010, he said.
However, Reuter said, the noise is caused by foot-traffic in the restaurant's parking lot.
