  • Finding ADU contractors near your residency will be easier if you check out their past projects and then request prices. This can help you compare their designs and the quality of the projects with the price they ask for their services. If you notice any mismatch, perhaps these ADU contractors are not worth your time.

ADU Contractor Building Types

In recent years, ADU contractors have come up with various ADU types that are bound to satisfy any picky customer. The choice of the unit normally depends on your needs and preferences. The types presented below can be built by our company A+.

Detached ADU

Detached accessory dwelling units represent a separate construction built on the lot with an already existing home. Despite the highest price from other options on the list, these units provide the customers with the best privacy. This can be a very attractive feature for tenants and may provide you with additional income.

Attached ADU

This unit will be built in close proximity to your main property and is great for increasing the total square footage. Because it will have a common wall, it can be easily accessed, which is great for taking care of seniors living there. What is more, it can significantly increase the resale value if, at some point, you will have to sell your own home.


If the room in your house, like a basement or garage, hasn’t been used that much lately, perhaps it’s time to transform it into a modern and comfortable living space. With help from professional home builders, your old and unattractive property will be able to attract dwellers from all over California. Don’t worry, all the amenities and important areas will also be taken care of.

Junior ADU

The main distinctive feature of this ADU type is its size. These units cannot exceed 500 square feet. As for other restrictions, there are almost none. You will still have a kitchen area, a bedroom, a living room, and a bathroom. Taking a smaller size into consideration, the cost of the unit will also be smaller.


ADU Unit Construction Clarksburg, CA

Creating an ADU in California requires overcoming a grand number of regulations. This info concerning law issues in your city will be collected by our lawyers and passed to the team of architects and home builders who will use these rules in the creation of accessory dwelling units.

For example, ADU contractors will have to place the unit five feet away from the front property line. Also, special non-flammable materials will be used in the construction to provide fire safety. What is more, every project must require a certain height of the unit, which varies based on the ADU type you choose for your backyard.

Benefits of ADU Building

Based on our experience with past projects, homeowners find many ways to use an ADU. These units are extremely beneficial for the homeowner’s family. The abundance of advantages that one unit can provide offers the opportunity to significantly improve one’s quality of life.

While considering building an ADU, take the following benefits into consideration:

  1. After local ADU contractors finish building a unit for you, the total value of your property will increase. The ADUs of good quality will give you huge profits if you decide to sell the whole lot.
  2. Hire an ADU contractor, and soon you will have living space in your side yard which can accommodate dwellers willing to live in Clarksburg, California. On your request, our team can add extra features like an additional bathroom or bathrooms to make your Detached ADUs more attractive than other local accessory dwelling units for possible tenants.
  3. With quick remodeling after we finish building an ADU, the unit can be transformed into anything you want. For example, it can become a place where you will practice your hobbies.

  • Frequently Asked Questions

    How long do you build one unit?

    It’s kinda difficult to say how much time it takes as every ADU is different and we cannot give you the correct estimation. The time will depend on materials, the difficulty of the project, the amount of legal documents, location, and much more. But on average, it takes us around ten months to complete an ADU.

    Do you operate only in Clarksburg, California?

    Our company has completed ADUs all over California, including Elk Grove, Citrus Heights, and even Sacramento. Even though obviously, other contractors are no match for us, you can read through customer reviews to make certain of the quality of our services. As for other contractors, you can check out their past projects and then request our list of completed ADUs and notice the considerable difference.

    How to understand what reviews to trust?

    If you are unsure whether the reviews provide you with truthful info, you can do a simple customer reviews check. The reviews must sound as natural as possible and have small details that cannot be invented by other people, like truly personal experiences. What is more, the attached photos are also vital. If they are done on an unprofessional camera and look amateur, it is a true review you are reading.
