What is an ADU?

An ADU is a structure that is specifically designed to be a standalone unit and is often referred to as a backyard cottage, or granny flat. It is a space that can include features such as a bedroom, bathroom and kitchen to be occupied, or be left spacious to utilize as an office or gym instead. It can be fully customized to suit your needs. 

Benefits of building an ADU

There are a plethora of benefits to building an ADU. Here are some of the most popular. 

Multiple uses 

As mentioned above, the ADU can be designed in any way you prefer. It is a quick and easy way to add space to your property and turn it into a pool house, a vacation rental, an office, a shed, a man cave, a guest house, and much more. Once the structure has been built, you can add your creative flair to the space. 


The cost of living, and the property market, only continues to rise. This is what makes an ADU the perfect addition to any home. Whether you are looking for an extra income stream by creating a home that can be rented out, or provide your family with the additional space at a fraction of the cost (and hassle) of moving house, an ADU could be the right solution for you. 

Simple process

With a professional contractor who is experienced in building ADU’s, you can expect a hassle-free and simple build. They will have the expertise, knowledge and tools to build your ADU to a high standard. Once you have discussed your specifications, you can sit back and relax.

How can you build an ADU?

The great thing about the Californian boom for ADUs, means there are multiple laws in the state to facilitate your project. Legislation has been passed over recent years, which has helped promote the use of ADUs and made the approval process much more flexible. 

To build an ADU in California, you must first meet the criteria. This includes:

  • owning a single-family home
  • occupying a large enough area to build a structure (this can be attached or detached)
  • the ADU must not be bigger than 50% of the square footage of your main house
  • space for an extra parking space (this only applies if you are more than half a mile from public transit) 

Once you have ensured you meet the criteria for an ADU in California, you can hire a professional contractor who will be able to design and build the ADU of your dreams. Make sure you check their portfolio and reviews to get an idea of their previous experience and reputation, so you can choose the right one for you.
