Usually, those who are planning to buy a house for the first time often face the problem of lack of space. What to do in a situation when you need extra space for the detached garage or your needs? But you like this house and its plot so much that you do not want to let it go! There is a way out, and this is an accessory dwelling unit.

The accessory dwelling unit is a very elegant way out of the difficulties caused by the lack of living space. This is an additional extension to the house or a separate room that you can use for any needs. This will embellish your home and historic district a little and later become a valuable investment.

A+ Construction & Remodeling company will handle your project as comfortably and quickly as possible, take into account all your preferences and wishes, and make your dreams come true.

Folsom ADU builders for hire

But first, to build an accessory dwelling unit in the Sacramento area, you need to know all the laws and understand which applicable building permit you need to apply for the new construction of dwelling units in the state.

Restrictions on the lot size

Local authorities of the City of Folsom, CA, do not set any restrictions on the size of your property, it can be of any shape and size, and you have the right to get building accessory dwelling units to permit. Therefore, you do not have to think about whether the minimum meets the requirements.

The permitted area of your ADU

The allowed size of your accessory dwelling unit depends on the type of accessory dwelling unit that complies with your needs. This means that the size of detached  ADUs with a separate entrance to your property will be different from the allowed size of the attached ADU. We will tell you more about the types of ADU below.

Minimum of setbacks

Your accessory dwelling units should be built at least four feet away from the side and front property line of your residential property. There are also rear yard setbacks that you should not forget about. So take care of both side and rear setbacks. Those required front yard setbacks and rear yard setbacks are very important, as they will only improve your security. It does not apply to a junior accessory dwelling unit, but a transformed ADU must be moved some distance away from your living area. Moreover, make side and rear setbacks; all this will ensure fire safety and protect your detached ADU.

Permitted places

If you have a territory that allows you to build a new building in addition to the main building and you have a single-family house, then you will have no problems obtaining a building permit. It is also possible to build an accessory dwelling unit for owners of apartments in houses for many families, such as a triplex. However, be careful; you will have to pay the historic district commission if your ADU is located in a historic district.

The maximum number of ADU

In the city of Folsom, a maximum of one or two accessory dwelling units per family is allowed. It all depends on the size of your territory. In the case of apartment buildings, everything depends on the number of apartments in the house and the type of accessory dwelling unit.

Parking requirements

The law requires a separate parking lot for a free-standing accessory dwelling unit (unlike for an attached one). In addition, the transformed accessory dwelling units and the junior accessory dwelling unit do not require a separate parking lot.

Fire safety rules

The state law does not say about the mandatory installation of fire sprinklers. But still, we recommend installing them to avoid problems. Also, try not to leave combustible substances in the open space. And why not secure an already existing home with fire sprinklers as well? Do not forget to learn fire codes in case of an emergency. However, even in their absence, you might have no problems with obtaining a building permit.

Permitted height

According to state law, you are required to build a one-story building, at least sixteen feet tall, so that it can serve you properly.

Before planning your accessory dwelling unit, be sure to familiarize yourself with the laws of the state so that you know how to get a permit. But, there is a more pleasant way out! A+ Construction & Remodeling will definitely take care of the legal security of your construction.

ADU Contractor in Folsom, West Sacramento

Why should you improve your rather comfortable existing space? Why do you need ADU on your land plot? We will make you familiar with the five major advantages of ADUs that will change your mind.

Use an old garage for living

Remember how as a child, you have always wanted to become a performer or do something with your own hands. So why not start now? A+ Construction & Remodeling will help you make your dreams come true; we will create the perfect space for your creativity so as not to distract other family members with a loud noise. Or maybe you have dreamt about turning your old garage into something more useful for a long time. This will no longer be a problem; after a little refinement, you will enjoy a brand new accessory dwelling unit. This will be extremely helpful if the off-street parking lot is not your priority anymore.

Accommodate your parents in ADU

It often happens that old people are not very comfortable living far away from their children. They are already very weak, and they need care, so it is a good idea for them to live in accessory dwelling units. We are sure that it is hard for several generations to live in a single-family house, but with an accessory dwelling unit, you will solve this problem easily.

Make a guesthouse

At first, gatherings with friends are cool and fun until the moment when they stay for a few days. We agree that this might be a little annoying, but we want to preserve your strong friendship and suggest using an accessory dwelling unit as a small guest house.

Increase your rental income

Very often, in search of inexpensive housing, students go to the suburbs and rent buildings like accessory dwelling units. It helps a lot to save them money, but it will also bring profit to you by renting your primary dwelling unit short- or long-term. Use it for extra income!

Increase the price of your house

Every year, real estate prices in the states are growing more and more, and at such a time, accessory dwelling units can be a good investment, as it is very convenient. You can invest a small amount of money to build an accessory dwelling unit. As a result, you will see how the price of the house will increase just in a few years. Detached ADUs that are built near an existing primary dwelling will be great in this case.

ADU unit construction in Folsom, California

Now we can move on to familiarizing ourselves with the types of accessory dwelling units. There are not many of them, and there are only five types:

  • Converted accessory dwelling unit. A very convenient type of unit, which implies the creation of a special non-residential premise from existing space. Its advantage is that minimum effort is expended. Moreover, you decide for yourself how it will serve you. The main disadvantage is a little practicality.
  • Detached accessory dwelling unit. You can easily add a fresh look to your home located in a historic district and add practicality to it by adding a small detached ADU to the existing primary dwelling. In a detached AUD, there might be two or more bedrooms and at least one bathroom. Well, definitely, the neighbors will be jealous of such a nice detached accessory dwelling unit.
  • Primary dwelling unit. You can build yourself accessory dwelling units that stand not far from your house, with a separate entrance, and use it as you want! It is nice, practical, and inexpensive. In addition, it adds value to your land plot. What else is needed?
  • Junior accessory dwelling unit. It is the same extension, only smaller and with less potential, but junior ADU is very convenient if you do not need large buildings of one thousand square feet.
  • Other. You can tell our architect how you see this existing detached accessory structure and come up with your own unique design of an ADU.

On the A+ Construction & Remodeling website, you can choose the type of extension you need. Make sure that an accessory dwelling unit complies with your needs. Specify the filling of your future ADU, specify the Folsom area and find out the approximate price of the ADU of your dream.
