If you have plenty of existing space on your property lot, why not turn it into something useful? Any property owner who wants to add a functional piece to the parcel can build an accessory dwelling unit. In addition to your primary residence, constructions like accessory dwelling units can be used either for residential purposes or for something else, like an office or a studio. No matter what your goals are, an ADU can be very convenient to have on your lot.

Building accessory dwelling units, or ADUs, can seem like an easy task from the first sight. However, there is a lot to take care of, even in the planning stage. That is where a contractor can help you.

A+ Construction & Remodeling can not only make a plan of ADU that would get approved by the governmental authorities but also construct a perfect accessory dwelling unit for you, considering all of your preferences and legal requirements as well. ADU contractors near me.

ADU Builders McClellan, CA

An accessory dwelling unit (ADU) is quite a common legally-established construction property owners build next to the primary residential structure. There is a chance that you have heard about ADUs but did not know it was actually them. Accessory dwelling units sometimes are called granny flats, in-law units, or just secondary units. All of these names indicate quite the same thing.

There are plenty of ways that you can use your accessory dwelling unit. For example, if you have elderly parents or relatives who need your care, you can move them into your ADU. In this case, the building may rightly be called a granny flat. Also, you can have your guests stay there when they come over instead of being all packed in the primary dwelling unit. This way, the guests won’t disturb your usual routine, and you will provide them with a comfortable private stay.

If you are not planning on turning ADU into a solely residential place, you can use it as your home office. It is especially convenient for those who have started working from home during the pandemic. This will help you to create an environment that is perfect for productive work. You can also use accessory dwelling units as studios or workshops.

Many homeowners look for opportunities to increase the value of their property. Accessory dwelling unit gives you such a chance, and it can make the cost of your lot even higher. You can also rent the place to others and get some additional income from it.

Depending on the existing residential units and other constructions on the lot, your accessory dwelling unit can be of several types: an attached ADU, a detached ADU, and a junior ADU. The attached accessory dwelling units are connected to the primary dwelling unit. Detached accessory dwelling units are usually separated from the primary residence. Junior ADUs are, in general, smaller than the other types, and they can be either built anew or converted from some existing structure.

No matter what type of accessory dwelling unit is your goal, A+ Construction & Remodeling can build it for you. New accessory dwelling units built by our company are some of the best ones not only in McClellan but all over California as well.

Some might ask: “What is so difficult about building an accessory dwelling unit (ADU) by yourself?” Well, there is a lot to consider. To get approved by the authorities, plans for the new ADU units have to be created according to all the laws and legal regulations. Making sure you do everything right might be exhausting. Moreover, you have to take care of all the materials to buy, and we don’t even talk about the process of building an ADU unit itself.

Here are some of the rules and topography and site constraints that your ADU project has to comply with in order to be approved and considered as a legal construction:

  • Detached accessory dwelling units must be no bigger than 1,200 square feet. For the attached ADU unit, the size cannot exceed half of the existing floor area of the primary residence or 850 square feet (depends on what is bigger). Junior ADU size cannot be more than 500 square feet in size.
  • The number of ADUs allowed per lot is two. The overall lot coverage of junior, attached, and detached ADUs cannot be more than 1,200 square feet.
  • For multi-family lots, it is allowed to have an accessory dwelling unit (ADU) per each four existing residential units.
  • Because of some setback requirements, ADUs must be at a certain distance from the front property line and other borders. For a converted ADU, there are no restrictions on the property’s zone setbacks. However, a one story building has to be no less than 60 feet away from the front property line. As for the two story setbacks, ADUs with two floors must have a four feet rear yard setback and the same for the side yard.
  • No fire safety measures are required, only if your primary dwelling does not fall under fire sprinkler requirements.
  • There are plenty of design guidelines applicable to the project. Exterior materials must be compatible with primary single unit dwelling and other existing units. If the ADU unit balcony, open stair landing, or any other universal access design features, are located towards the side or rear lot line, they have to be at least three feet in height.

And these are not all of the site constraints for one accessory dwelling unit. Even if the design does not match, your project might not be approved. Whether you have a single-family home or multi-family residential parcels, single unit dwelling or the one with more than one bedroom, certain rules have to be followed.

Now that you know how much needs to be done for the construction of one accessory dwelling unit, you see that it is a lot of work even for a whole family. Luckily, there are professionals from A+ Construction & Remodeling who can help you with planning and building.

ADU Construction Company McClellan?

When you want to build an addition to your primary home, you might want to look for a good ADU builder. You should choose a quality service provider if you want the final result to be good. There are several criteria that one should consider when picking a builder for the ADU.

First of all, pay attention to licenses and permits. They prove the legibility of the company and also reassure you of the safety of constructions it makes.

Second of all, check the previous projects completed by the contractor. See what types of ADUs they usually build, how they manage utility connections, and how the ADU matches with the primary single unit dwelling, surrounding neighborhood, and other design guidelines applicable.

Also, don’t forget to read reviews of previous customers. They help you to compare pros and cons of the company’s work and make the final decision. Sometimes, clients can tell you much more about the projects than the builder company does itself.
