Constructing an accessory dwelling unit (ADU) provides additional living space on a property. These independent units, often referred to as granny flats, in-law suites, or secondary suites, contain kitchen and bathroom facilities, allowing for separate living arrangements. For instance, a homeowner might build an ADU to house an aging parent, a returning adult child, or even generate rental income.
ADUs offer significant advantages, including increased property value, multigenerational living solutions, potential rental income streams, and a flexible response to evolving housing needs. Historically, ADUs have served various functions, from housing extended family members to accommodating domestic staff. The growing popularity of ADUs reflects contemporary housing challenges and the desire for adaptable living spaces.
