Multi-family housing refers to residential buildings designed to accommodate multiple separate housing units. These structures can include apartments, condominiums, and townhouses, allowing several families or individuals to live in close proximity while maintaining their own private living spaces. This type of housing is often found in urban areas where land is limited and demand for housing is high. Multi-family housing can offer various amenities, such as shared recreational facilities, parking, and maintenance services. It is typically managed by property management companies or homeowners' associations, ensuring that common areas are well-maintained and that residents have access to necessary services.
