ROCKLAND, Maine — Two more families will benefit when local builders volunteer their time in early June to help construct two new homes.

Midcoast Habitat for Humanity is participating in a nationwide “Home Builders Blitz” that will kick off on Brewster Street in Rockland at 7 a.m. Monday, June 6. Nearly 250 projects are expected to be built across the United States during the week of June 6-10, according to Midcoast Habitat for Humanity Executive Director Tia Anderson.

In Rockland, Cold Mountain Builders, Phi Home Designs, subcontractors and suppliers will work with the local Habitat for Humanity chapter to build the two single-family homes on a lot adjacent to a home Habitat completed earlier this year.

The two homes will mark the 29th and 30th residences constructed through Habitat in Knox County since 1990.

The local Habitat chapter, located in Rockport, also offers rehabilitation, weatherization and repairs to homes. In addition, Habitat operates a second-hand store on Route 90 in Rockport, offers homebuyer and financial education services and provides post-purchase support.

Habitat offers the opportunity of homeownership with zero interest mortgage to qualifying families who earn 30 percent to 80 percent of the area median household income. Selection also is based on a family’s ability to pay and willingness to volunteer time with Habitat.

The median household income in Knox County for 2014 was $50,515, according to the U.S. Census.
