Popular mother-daughter home designs include mirrored designs, multi-wing designs and small separate back houses on larger lots. No legal definition exists for mother-daughter housing; ultimately the term simply refers to separate living spaces in one house.
Real-estate agents are often prohibited from advertising mother-daughter homes because multi-apartment or multifamily buildings face different regulations than do single-family homes. At the core, mother-daughter homes have separate bedrooms and bathrooms, but they may also have separate entrances, kitchens and laundry facilities.
Mirrored floor plans offer identical rooms on both sides of a house. Multi-wing floor plans offer a central area which separates two or more separate wings. Small back houses also offer a popular and more private design option for larger home lots.
