ADU in Mountain View, CA

An ADU is ideal for families where one or both generations desire to be close while still maintaining some independence. An ADU allows them to stay close to loved ones while preserving their privacy. As an added bonus, it is conveniently located on the same land as your main residence, making it easy to get to each other in case of an unexpected event.

An ADU is a smart and affordable option for a new home addition. Comfortable living quarters can be established rapidly, and the fact that they can be constructed without acquiring extra land is yet another advantage. Because of this, ADUs are a fantastic choice for homeowners who need additional room but don’t want to deal with the trouble or price of relocating to a new location.

You can customize an ADU to meet your specific requirements and preferences. Custom cabinetry, granite countertops, stainless steel appliances, hardwood floors, and energy-efficient windows and doors are just some of the modern design amenities available to you. With these modern enhancements, your ADU will be a family heirloom for years to come. Contact Acton ADU  if you’re planning on adding an ADU to your home.
