Benefits of ADU Building

Benefits of ADU Building

  • Additional Income: having an ADU on your property that you can rent out for additional income is a project that will pay for itself. Some homeowners are adding an ADU to alleviate their mortgage payment in the long run.
  • Guest House: an ADU will give you an option to host guests without disturbing your lifestyle. Having guests stay on the property but not necessarily in your home, makes it easier for the homeowner.
  • Living Quarters for Parents: if you have aging parents that you want to take care of in the comfort of your own space, having an ADU will make it possible for them to live close to you and yet let you have your own home for comfort.

Plan & Layout

Building ADU in Wilton

Prior to starting the construction of the addition to a single-unit dwelling, you need to submit some forms to the building department of the city. Moreover, various zoning rules of your neighborhood must be followed in constructing the ADU in Wilton, Sacramento, CTY.

The minimum lot size for putting an ADU on it is not regulated. However, your property must be appropriate for residential purposes. Owners of single-family houses are allowed to build 1 or 2 accessory dwelling units, while multi-family residences can have more than 2.

Each accessory dwelling unit (ADU) must be of the same architectural style, color, and building interior as the primary single-family or multi-family housing unit.

Standard ADU cannot be less than 150 square feet and cannot exceed the size of 850 square feet (in some cases, 1000 square feet). The maximum height of a detached or attached ADU is not regulated anyhow. The floor area of the latter must not be bigger than 50% of the primary residence size.

There are some setback requirements as well. Multi-story detached and attached ADUs must have no more than 4 feet of the side yard and rear yard setback. One-story ADUs and those with lot coverage less than 800 square feet do not comply with such setback requirements, but they have to be placed no less than 60 feet from the front property line. A multi-story accessory building does not have to follow the property line rules. Converted ADUs do not have to meet any setback requirements (no side yard or rear yard setback needed).

If your primary residence is located half a mile distance from public transportation, there is no need to have an additional parking space for ADU. Moreover, if the accessory dwelling unit (ADU) was converted from a garage, there is no requirement to substitute it for another one either.

No special fire safety equipment is a must, but the owner is advised to provide some kind of fire protection.

Prefab ADU Construction

All of our attached junior and detached ADUs are prefabricated in order to make our services quicker. We assemble them near the city of Sacramento, CTY. This way, the contractor’s work on your property is as minimized as possible, so you cannot be disturbed by the building noise as much as possible.

If you have any questions on how and where your contractors create the ADU, you can ask them during a free online consultation with our specialists.

ADU Housing

Having attached converted, junior or detached ADUs on your property is very convenient, as you can turn the space into anything you would like. Here are some options on how you can use your accessory building.

Personal office

Having the office at your property is very comfortable for those who are working from home or just need a private space to go about their business. A place different from your home environment and no drives all across the city permit you to be at your best working conditions right at your back or side yard.


If you are used to having a lot of visitors regularly, then this is the best option for you. Use your accessory lot coverage to accommodate your relative from another city or to have friends stay overnight. This way, you would be comfortable in the privacy of your house and still be sure that your guests are having a great time.

Renting the place

Another alternative is to rent your ADU to someone and get a stable source of income. It is even more comfortable than leasing a usual apartment or house in the city: you can supervise the place as it is on your property line and be sure that it is treated properly by the resident.

Home for the elderly

Those of us who have old parents or relatives are probably familiar with the problem of not being able to take regular care of them, because of the long distances between houses. Having ADU solves such an issue. You can move your elderly to the place right by your side and be sure they are safe and sound.

Frequently Asked Questions

How much does a prefab ADU cost?

The prices of ADUs in Wilton, Sacramento CTY, vary quite differently. Each prefabricated ADU’s cost depends on the size of the construction, materials used, duration of work, size of the primary housing unit, and whether you want it attached or detached.

You can calculate the preliminary cost for your accessory dwelling unit during the first online consultation with our contractors. It is payment-free, so submit your application and be insured of how much you need to spend.

What can I use my accessory dwelling unit for?

Accessory dwelling units are very useful, as they can be turned into any practical premises you want. You can create a home office and work right by your house. There is also an option of making it a guest house, where your visitors can relax in the comfort of their own privacy. Have old relatives who need your constant care? Move them into your ADU and be sure that everything is alright all the time. There are a lot of possibilities, so you should definitely have an accessory dwelling unit on your property!

    Before moving to our new home in California, we decided to give the kitchen a more personalized feel. We contacted A+ Construction and Redemoling as a recommendation from a friend. Their designers took us through a number of designs. Today, all friends admire our kitchen. They truly didn't disappoint.

    A+ Construction and Remodeling guys are the best! They helped us make many home repairs to prepare for listing our old home and are helping us right now with the set up in new house. The production team was fast and professional, and I love my new remodeled kitchen. Wouldn't hire anyone else!

    They did an amazing job on our bathroom! Workers were friendly, clean and on time. They always kept in touch with us regarding anything that came up and even gave us updates on the work. Very responsive to my texts/calls if I had any questions. Will definitely use them again for any of our other remodel projects.

    We hired A+ Construction & Remodeling to convert our garage to an ADU. Both our project manager and the construction team were pleasant to work with. They were always on time and managed to finish the project even before the deadline they set for it. We are extremely pleased with the outcome. We would recommend A+ to anyone considering a home remodel or new construction.
