An ADU (Accessory Dwelling Unit), also known as a granny flat, is a small, self-contained living space built on your property. ADUs are ideal for generating rental income, housing an extended family, or even creating a private office. They can also add significant value to your property.
The timeline for a kitchen renovation depends on the complexity of the project. On average, a full kitchen remodel can take anywhere from 4 to 8 weeks.
