GULFPORT — Tammy Mohns and her three sons have a new home thanks to thousands of volunteer hours and Habitat for Humanity. She received the keys last week to the three-bedroom, two-bath stucco home on Ninth Avenue S, the first new build for Habitat in Gulfport.Mike Sutton, CEO of Habitat for Humanity of Pinellas County, said although the organization has renovated a few homes in Gulfport over the years, the Mohns' home is the first new build."Gulfport's historically been a challenge," he said. "Part of it's in a flood plain (where we don't build) and single lots have been hard to come by. We're delighted to be in this community, and already have plans for a second house in the city."Mohns, a single mom who works two jobs, and fulfilled all the organization's requirements including building some of the home herself, said it was the realization of a dream. "I've never had a home to come home to," she said. "Now I do, and my boys have a home they can come home to."
