ADU Contractor Building Types

To create an ADU, you should consider the types of units that you might be interested in. The choice of the right type usually depends on the property owner’s preferences and the possibilities of the lot.

The following are the most common types of accessory dwelling units in California:

  • Attached ADU;
  • Detached ADU;
  • Junior ADU;
  • Garage conversion ADU.

Your construction plans will be made based on the type of new construction you opt for. In general, they differ in size and proximity to the main house. ADUs converted from a garage include renovations of an already existing area.

If you don’t have a particular vision of an ADU, or you’re still not sure which one to choose, our employees are more than ready to give you some useful suggestions and provide a full layout of why one or another type might be more suitable for your needs.


ADU Unit Construction Olivehurst

All the ADU projects go through the same procedure, although some features might change depending on the specificities of your ADU. Want to know what to expect?

Here are the main steps of building an ADU with general contractors:

  1. Discussing the project details, calculating price estimates, and looking at the property capacity;
  2. Designing the interior rooms, like bedrooms, bathrooms, or kitchen, and creating architectural plans of the construction;
  3. Sending the plans for review to the local government and receiving a building permit;
  4. Starting the construction work;
  5. Working on the design, installing siding, and painting the walls;
  6. Providing electrical and plumbing systems to the new unit.

The fantastic thing about hiring professional contractors is that you don’t have to search for a separate specialist for each service. A+ allows you to create an ADU in the most time- and cost-efficient way and live your life peacefully.

Benefits of ADU Building

Accessory dwelling units are more beneficial to homeowners than they might seem at first sight. Although it’s not a whole house that gets built, it still can give you plenty of advantages both while using and in the future.

Take a look at all the amazing qualities that a secondary unit has:

  • An ADU increases the value of your property, which can be very beneficial if you ever decide to sell the property.
  • An ADU can be the answer to some financial problems. These units are perfect for renting out and receiving some extra income; you can always be aware of what is going on with your property.
  • The additional unit can serve as a guest house for your visitors or as a granny flat for your elderly relatives who need care.
  • To be honest, there are numerous ways of turning your ADU into some fun area: a home cinema, a personal gym, a sunroom, or even a playing zone for your little ones.
  • An ADU can become your home office, where you’ll be able to do your job and respond to emails in a peaceful environment.

  • Frequently Asked Questions

    How to choose a general contractor for an ADU project?

    ADU contractors should be able to make a unit that not only looks beautiful, but also serves its purpose most efficiently. When looking for contractors in Yuba county, pay attention to the previously completed projects and reviews left by other customers.

    What kinds of ADU projects are there?

    A+ contractors can build one of the common ADU types for you: a detached ADU, an attached ADU, a junior ADU, or a converted ADU. While the attached and junior kinds are usually connected with the main home, the other two stand separately on the lot. Converted ADUs are created by transforming a garage into a proper living place.

    Does ADU require a building permit?

    To start building an ADU in California, you must receive a permit. It is given by the local officials in case your project plan complies with all the legal regulations stated by the state and local laws. If there are any mistakes in your plan, corrections should be made. Then, you apply for the document once again, but this time, you have to pay a fee as well.
