A Camden-based organization that serves adults with developmental disabilities plans to build a home in Rockland to house eight of its residents.

Coastal Opportunities purchased a 5-acre lot from the Rockland Congregational Church Nov. 13. The lot is separate from the church lot, but is adjacent to the rear (west) of the church.

Coastal Opportunities Executive Director Joseph Curll said the house would replace the 29-year-old Katherine Brown Home — a group home in Hope. The Rockland project would be a one-story, 3,000- to 4,000-square-foot building.

Construction is expected to begin in about a year, he said.

The organization is working with the U.S. Department of Agriculture Rural Development agency for a loan to build the home.

Code Enforcement Officer John Root said that a state-licensed group home must be considered a single-family home by state law if it serves eight or fewer residents and is an allowed use on the property.

No application has yet been submitted to the city.

The church has owned the wooded property since 1986.
