In past years, it became slightly popular to establish extra housing right on the same lot as the main home. For some Sonoma County dwellers, it may be surprising to know that their residential property can be not only expanded but also produce extra income. However, all these features are united by one structure called an Accessory Dwelling Unit (ADU).

Accessory dwelling units are small residence constructions located on the same lot as the main dwelling unit. Also referred to as ADUs, they may have various names throughout Northern California, including granny flat, in-law units, secondary suite, accessory dwelling, and casita.

Establishing the building process implies several requirements, but it is still easy to set the new construction on your living space. However, the majority of homeowners do not succeed in avoiding pitfalls during the development process. In this article, we will accompany you to the ADU of your dream, even if you have never considered its project. Stay with us for broader instruction on how to set the ADU, where to find the contractor and builders, and what are the purposes and benefits of building Accessory Dwelling Unit  Sacramento.

Vineyard ADU Builders

Building and constructing any structure, including accessory dwelling units, requires a big working experience. The builders of A+ are mentioned by local journalism numerous times because of the friendly pricing policy and example of the hard and polite work with residents.

Depending on your budget and lot size, we will estimate the possible parameters, exact cost, and design of the new housing. Since granny flats are a popular kind of additional living space, our masters have a great experience in building such constructions.

No matter whether you are only thinking about establishing your first ADU or planning to add a new level of the same property, we will help you to create the best variant of ADU for the least money and time expenses!

ADU Unit Construction Vineyard

Now we are ready to move further into West Sacramento accessory dwelling units building details. Further, you can find the legal requirements for ADU projects in Sonoma County.

Types of ADU allowed.

Depending on the basis of the ADU construction, there are several types of such property distinguished:

  • The attached ADU is a part of the primary residence. For example, you can add a new part to the existing building so that attached ADUs will share some rooms, or in contrast, will have separate entries with the main house.
  • Detached ADU is a small separated housing located near the primary residence that has its own bedrooms, bathroom, kitchen, plumbing, and heating systems, if any.
  • A converted ADU is an old unused building on the lot (e.g., studio, shed, or garage) converted into dwelling detached ADUs.
  • Junior ADU is, same as an attached ADU, a part of the main house. However, its distinction is that it shares the bathroom with the primary building.

In California, it is allowed to build ADUs of any type, so you are free to choose which one is the most applicable for your residence. Choosing the type is exactly a starting point of launching the building project.

Number of ADUs allowed.

California state law has a distinction between single- and multi-family housing in this topic. So, for a single-family residence, it is allowed to have one accessory property and one junior ADU on the lot. For multi-family homeowners, it is allowed to have one ADU per every four residents.

Fortunately, in West Sacramento, there are no regulations for the minimum lot size for having an additional unit built. That is why ADU is considered to be affordable housing. It can fit any lot size and type of the main house.

ADU parameters.

However, unlike the previous features, the size of each ADU is strictly regulated by state law. So, you also need to check whether the initial footage of your lot will suit these requirements. The professionals can help you to estimate the project depending on the free space on your land property.

The minimum possible size of any type of ADUs is 150 square feet. The maximum footages of ADUs in California are as follows:

  • no more than 500 square feet for a one-bedroom ADU;
  • no more than 850 square feet for two-bedrooms ADU;
  • no more than 500 square feet for junior ADU.

Note that the total lot coverage of the ADU must be no more than 1200 square feet. Otherwise, the building permit for your project cannot be obtained.

For any ADUs type, the maximum height of the construction is 16 feet. The units should be no less than one story.

Setback requirements.

State law of Sacramento County singles out many requirements towards the location of the accessory dwelling unit on the lot. There should be a certain space conformed to each part of the lot and the primary residence. The new construction must be situated 60 feet away from the front property line. A two-story detached ADU must meet the 4-feet yard setback requirements.

Note that ADUs converted from a garage or other old constructions do not meet the setback requirements!

Design of the ADU.

Although the interior design is a private deal, the outside appearance of an accessory dwelling unit should conform to the style of the primary house. It would seem that for property owners, it should not be a tricky matter. However, it is better to ask an architect or a designer to make the development of the ADU project so it would correlate with the main style of other units.

Nevertheless, each owner should care about the general appearance of their property and their own comfort, so it is better to use the same materials as the main housing. You can specify the ADU’s purpose by choosing specific wood, stone, or metal equipment.

Vineyard ADU Construction Company

Being on the market for more than 20 years, A+ Construction and Remodeling provides the most care-taking service, which is seen in hundreds of pleased customers’ reviews. By gaining experience in building complex ADUs, our builders make a big amount of Wine Country families happy with their new dwelling unit remodeling. That is why we prefer to make our work honestly and professionally because seeing the whole city of beautiful and quality housing with happy owners is exactly what we want to see!

ADU Building Vineyard

After all, you may still question yourself why it is necessary to have an accessory dwelling unit on your lot since you already have a residence with comfortable conditions. We will try to convince you that ADUs are irreplaceable types of housing units in our country.

So, the majority of Sonoma County dwellers prefer to establish ADUs for the following reasons:

  • ADUs increase the value of the property. For many single-family housing owners, the important part of their residence is its value. That is why they prefer to set the ADU, even by converting it from the old garage. If you plan to resale your lot, be sure that the ADU presence will increase the final cost of the land several times.
  • ADUs supply you with additional living space. No doubt that for any homeowner, there is no redundant residential space. Extending the footage of your property can bring you many benefits. Starting with the fact that you can have a big amount of guests staying in comfort, right until the possibility to house your relatives for some time in case of unseen circumstances.
  • Create a rental ADU. Not surprisingly, you can use the additional space not only for free. By establishing an ADU, you can increase housing affordability in your area. Rent your ADU out to provide yourself with a rental income and give someone an opportunity to have a small house near their temporary working place for some time. However, ADUs for rent are better to be detached, so you will not have to share your private space with unfamiliar people.
  • ADU as a guest house. Another way to gain an additional income is to unite two previous purposes and set a small hostel. Be sure to familiarize yourself with all the needed laws, and set up your business.

All in all, any development of your residence brings you multiple benefits. However, establishing ADUs can be the most profitable investment in your property with the lowest costs wasted. No surprise why so many homeowners set these additional suites on their lands.

Take your time to weigh the pros and cons of such a decision but be sure that ADU will never be an extra option. Anyways, you can just convert an unused construction on your lot into the ADU just if you want to try your designing abilities!

Prefab ADU Construction

Prefab constructions are ready-made structures of ADUs. They are the best choice for those who do not consider spending too much money, time, and effort on the building process. However, except for the low costs, prefab ADU is also low in its uniqueness. Be ready to meet similar constructions on other homeowners’ lots. Nevertheless, it is a great variant for a big family case, when it is not likely to set a long building process right near the primary residence.

So, prefab constructions are popular for their low costs, affordable timings, and uncomplicated designs.

  • Frequently Asked Questions

    How much does a prefab ADU cost?

    As was mentioned in the article, the cost for ready-made structures is commonly lower than for constructions from scratch. For prefab construction costs, the price is considered per square foot and often is not higher than 500$. However, the prices vary from state to state and also depend on the material, parameters, and amount of the ADU equipment.

    What can I use my accessory dwelling unit for?

    There are many ways in which the ADU suits well. The purpose of its utility depends only on the creativity of the homeowner, but the most frequent usage strategies are extending the residential space for rent, just for comfort, or for increasing the cost of the property. It can also be used as a kitchen, storage, or even a spa zone.

    How much does it cost to build a granny flat in the City of Sacramento?

    Costs for establishing ADU in Wine Country are one of the most loyal. However, the prices are almost unpredictable as the costs for each unique case are considered only after estimating the difficulty of the project realization and the quality of the materials. Nevertheless, the price per square foot is less in the case of accessory dwellings than for the primary buildings.
