Why Build Accessory Dwelling Unit?

Building an additional unit takes a lot of resources such as time, money, and energy. Preparing for the construction of ADU, you should be sure that it is reasonable for you. There are several ways how you can use unit dwelling in the future.

1 — Renting Out

As a unit can become an additional house, you can use this way for the establishment of a passive income. Of course, this unit should be well-planned and have a good location to be attractive for people visiting it. If it is the main reason for you for the building of new construction or using a converted space, you should think about all the details to make a stay comfortable for renters.

2 — Guesthouse

It is much convenient for you and your guests to have separate bedrooms, kitchens, and bathrooms. That is why an ADU can become a perfect place for a short stay for your visitors. Equip the unit with all the necessary tools to make sure that your guests will enjoy their rest in your guesthouse.

3 — Workshop or Home Office

Remote work is very common nowadays, but sometimes it is distracting to work at home. You can build a home office that will have the furniture and environment needed for your job. The unit will be a good place for you to separate your working and living space.

4 — House for Family Members

You can avoid such situations if one of the generations lives in another house. You still will have living places close to one another, but you will not bother each other with some activities in separate single-family units.

So, in addition to the listed reasons for building an ADU, you can come up with your own. The main point is that there are a lot of ways to use the additional unit, and it is always worth expenditures and time spent on its planning.

Building ADU, Granite Bay CA

The building of accessory dwelling units is regulated by state law in California. When planning an ADU, you should be aware of this law to avoid problems with the registration of a unit.

In this part of the review, we will tell you about the main criteria of ADU required by state law for the construction of ADU in Granite Bay.

Types of Accessory Dwelling Units

According to state laws, it is allowed to build three types of ADU:

  • Attached;
  • Detached;
  • Junior.

Moreover, you can build a new unit on your territory or use a converted space in your house. However, you cannot use the newly constructed ADU as a Junior unit. For this purpose, you can only create a converted unit in your home territory.

As regards these types of units, here are short descriptions of each of them:

  • Attached ADU is a space that is connected to the main house with a door or wall.
  • Detached ADU is a building that stays separate from the house. There should be a distance between the walls of the main house and ADU if you are planning this type of unit.
  • Junior ADU is a space that is smaller than 500 square feet. Keep in mind that the size of ADU cannot be less than 150 square feet to be a legal living place.

Allowed Number of ADU

You can build one ADU and one Junior ADU if the house is owner-occupied. However, if it is not your case, you can create only one ADU. When the property is multi-family, they can add more units. Thus, having four residential spaces, you can add one more ADU.

ADU Area Size

Based on the state laws, the maximum size of ADU should be 850 square feet if it is supposed to be a living place for one person. In case when two-person should occupy the unit, it can be extended up to 1,000 square feet.

Required Setbacks

The state law determines the maximum setback for detached ADU as 4 feet. As regards attached and rebuilt units, setbacks are required to be constructed according to rules set for the main house.
