What is an ADU?
What is an ADU? An ADU is an additional dwelling unit on an single-family property. An Adu may or may not be attached to the primary building. Typically, ADUs are smaller than the main family home. Finally, they are equipped with their own kitchens and bathrooms.
ADUs are also known as granny flats, second units, mother-in-law apartments, carriage homes and backyard cottages. They may also be called multi-generational homes.
Different types of ADUs
ADUs come in many shapes and sizes.
- Basement apartments
- Converted garages
- Converted attics
- Carriage house conversions
- Freestanding structures, including converted sheds and storage areas.
The average cost to add an ADU
The average costs are between $70,000 – $100,000. Assuming the ADU is rented out the time to pay back an ADU addition is 6 to 8 years.
- Clerestory windows and skylights provide year round natural light, thereby reducing electricity bills.
- Exposed beams, vaulted ceilings help ADUs ‘live large’
- Accent lighting adds beauty and usability
- Outdoor living areas, such as a small porch or covered patio attached to freestanding ADUs
- Open floor plans, to maximize flow and make ADUs feel more spacious
- Walkability. As many of today’s renters prefer a car-free lifestyle, neighborhoods with high walkability scores are especially well suited for ADUs.
