There are many great floor plans for a mother-in-law house, including those offered by Clayton Homes, as a modular or manufactured home option or site built options from planssourceinc.com, theplancollection.com and motherinlaw.coolhouseplans.com. Floor plans range from in-house suites to stand alone houses.
Floor plans for the mother-in-law houses are as varied as floor plans for any house. Costs range from $40,000 to several hundred thousand dollars. The plans available from Clayton Homes are for stand-alone, manufactured or modular homes. Set up appropriately, they are a quick way to create a completely separate and independent dwelling. Site-built mother-in-laws houses offer greater floor plan flexibility, but at a higher cost.
