Frequently Asked Questions — FAQ

What is an ADU?

ADU is an abbreviation for an accessory dwelling unit representing an additional secondary dwelling structure located close to the primary residence at the residential lot usually owned by one family. There are two main types of such structures, attached ADUs (resulting in the reconstruction of the existing inhouse space) and detached ADUs, which are the separate structures located on the premises territory. If you plan to build an ADU, you should find out the ADUs construction regulations established in your area. If the design of your attached or the detached ADUs conflicts with the design guidelines applicable for that of the primary residence, you won't be able to get the approval to perform the ADU building.

Can I cope with ADU construction myself?

ADU construction implies a lot of preparatory work. First of all, you should carefully learn the ADU building regulations established in your state. Secondly, the project design and all the cost calculations should be carried out. Thirdly, you must carry out the purchase of all the construction and decoration materials according to your cost estimate. Finally, the erection or reconstruction (in the case of the attached ADU) works should be performed. So, if you have enough expertise and experience in some areas of activity, you will be able to carry out the ADU all by yourself.

What is the price of ADU Construction?

The ADU construction costs are influenced by numerous factors, such as the type of your ADU (attached or detached), how many square feet your residential lot is, what size your potential ADU is planned to be, whether it will be a one-story or a two-story ADU, and many others. Generally, the ADU price tag can vary from 30 thousand to more than 300 thousand US dollars.

How long does it take to have the ADU built?

The average period of the new ADUs construction depends on whether you are going to erect a completely separated new accessory dwelling unit or reconstruct the already existing primary residential structure. As a rule, obtaining the building and reconstruction permits takes two weeks (the term may be increased in some cases), whereas the construction works themselves can take up to 4-To 6 months, depending on your ADU project

Accreditations & Certificates


In the modern world, where the construction of a personal dream house can cost a fortune and requires from the family enormous amounts of time, energy, and patience, tiny homes and accessory dwelling units (ADUs) represent a wonderful solution to the lack of living space in the cities. They are a great option for those who seek affordable housing units whose installation doesn’t require homeowners incredible amounts of investments as well as proper research beforehand in case they order accessory dwelling units or tiny homes from a professional team of builders.

Adu Builders California is here to make an ADU project a reality. If you would like to know more about the benefits of accessory dwelling units and tiny houses, the work of builders, and the key differences between these two buildings, read the following article.

Benefits of Having an ADU or a Tiny House

The disadvantages of these forms of property fade before the benefits they offer to a homeowner. There are many reasons for this attitude from society, so let’s examine them closely and figure out what’s all the fuss about.

ADUs Tiny Homes can boast the following advantages:

  1. Cost

If you saw the prices for property in San Francisco, you will be pleased to know that the amount of money needed to create our topical property doesn’t reach these numbers. For sure, it still takes some resources and quite a sum of money for families to start the building process of a unit, but to have it completed, you don’t need to sell your soul.

  1. Conscious way of life

If you have chosen to build an ADU, it is your mission now to follow an ecological way of life. Surely, it is an exciting adventure that you embark on, and it will transform your mundane living, but in the end, you will understand what amazing benefits it gives you.

  1. Opportunity to earn

A tiny house gives you access to do everything you want with it. On the Internet, you can find many articles concerning the ways of using it, and one of the most popular ones is finding tenants. It lets you use an accessory dwelling unit as a rental unit and gives an option to fill the family budget.

  1. Lavish life

A cozy apartment right next to your main house allows you to explore certain ideas for using it that weren’t possible before. For example, with it, you can start inviting your friends or relatives to your property so they can stay there overnight.

Work of Adu Builders California Builders on Your Tiny Home

Even though any homeowner can easily start bringing to life an ADU project, right now on the market, there are a variety of professional companies that stay in line and wait for you to hire them. They can do all sorts of things in the course of a project. At first, they design the concept of your future small home and finish with building affordable housing right on your lot! Further, in the article, we will compare in what way hiring a team is a better form of building a unit.

Planning and Design

You will not need to create a design on your own. The team will do it. Architects and builders will figure out together what materials to choose for both the exterior of your tiny house and the interior of any room, be it a bedroom, bathroom, or kitchen.


Even though the plans are created by the team, you can introduce your own vision into the project. Have you decided to change the tiles on the roof to better fit your main house? Not a question for us. Want to change the zoning inside the living space a bit? If it fits the law and local regulations, we will be excited to bring it to reality.

Services from Professionals

The team normally consists of a number of professionals whose knowledge covers different aspects of building an ADU. Take, for example, lawyers. They know and can lecture you about obtaining a building permit, the zoning rules in the area, the distance where your small home has to connect to the main house, and many other intricacies.

As you can see, even though hiring Adu Builders California may seem like a waste of money to you, the benefits it gives you will certainly outweigh the money you invest in it. In the end, having a guest house on the same lot makes your property a valuable asset in the eyes of a possible customer if you want to have it sold.


Valued Recognitions

ADUs and Tiny Homes: Side by Side Comparison

With the ever-growing cities, the cost of units and living space doesn’t seem to decrease at any time. More and more people are tired of living under one roof; others want to live closer to the city or even change the country, and your tiny home is a great option for them to start a new life. This affordable construction is a great choice for people with not enough resources to build their own living space.

But how do you differ between an accessory dwelling unit and a tiny house, and which option is for you? Let’s compare them now!

The differences between an ADU and a tiny house are the following:

Even though an ADU may look the same as a tiny house, they offer way more freedom. If you set up an ADU, you can expect a full bathroom or several stories; what is simply inaccessible is we talk about a tiny house. All in all, an ADU just represents a larger structure than a tiny house.

If there is a room that neither you nor your family uses, it can be transformed into an ADU by any builder, and you will get a place to live for a friend of yours who came for a night. Hence, you won’t spend a fortune on new construction, which makes an ADU a more affordable option than a tiny house.

Yes, you get it right – a tiny house can be built transportable. For sure, we can create a guest house using concrete, and you will never move it, but at the same time, there is an option to design a living space on wheels. Hence, a host will be able to travel around the world or around the country and stay in their house.

As you can see, there are some serious differences between a tiny house and an ADU, so you should choose wisely. Think of who will be living there, will they need a full-size kitchen, bathroom, or bedroom, or how much money you are ready to spend on it. However, if you are struggling, Adu Builders California is ready to help you.
