Obtain Permits

Our team will immediately begin obtaining permits and scheduling appointments with the necessary trade experts to guarantee your home is in the optimal state needed to begin the ADU construction phase. Your project manager will handle this process from A to Z.

Time To Shop!

This is the fun part! Time to shop! You and your project manager will take the time to review all the remaining materials, fixtures, and accessories needed for your ADU Design-Build from our most trusted vendors.

Step 4: Construction Phases

The initial phase of the actual construction will consist of us demolishing the area and removing all of the unwanted materials. Cleaning out the space in a timely manner will ensure that we stay on track with our Mountain View ADU housing project timeline and prepare us for the framing phase.

Framing and Preparation

Preparation is a key part of a truly smooth installation process, so it is incredibly important that we inspect the space after it’s been demolished and begin the process of framing the structure. As framing is completed, we can then stucco the exterior, interior drywall, plumbing, and other aspects needed to move on to the installation phase.


It’s finally here! The installation process is where your brand new ADU or garage conversion begins to take shape and finally comes to life. Your project manager will ensure that each step is handled with care so that everything is installed in a clean and perfect manner.

What do you do when someone you care about needs a place to stay? When they need a place to live, you do everything you can to ensure they have their place. A Mountain View ADU project is one of the best choices for building and providing extended family members with a place to live.

Constructing an ADU on your property is one of the best ways to increase your space. These projects require expert professionals, and you should consider hiring an ADU contractor in Mountain View that can provide plenty of assistance.

Hundreds, maybe even thousands of contractors, can handle a City of Mountain View ADU project. The guide will walk you through all the essential parts of the building process you must consider before hiring a construction company.

What is An Accessory Dwelling Unit?

Accessory dwelling units (ADU) are another name for second homes built on the same property as the main home. An ADU home must meet specific legal and governmental requirements. Even though the flat can’t be bought or sold by itself, people often rent them out or live with close relatives to make extra money.

Even though ADU homes have many perks, many people aren’t sure about the rules and regulations for building them. The new state, county, and city legislation incentivize people who want to create an ADU on their property.

When looking for an ADU contractor, choose a company who are also new homes builders in Mountain View, CA.

What Constitutes Accessory Dwelling Units?

An ADU unit must meet the requirements for a statewide exemption and must have no more than 800 square feet of floor space, no more than 16 feet of height (unless the local government sets a lower limit), and no more than six inches of yard space on the sides and back.

Local regulations will also have further limitations and requirements for ADU construction. Hiring a wise builder experienced in ADU permits and legislation is crucial.

Does An ADU Have its Address?

Most cities do not require a separate address for accessory dwelling units. Although it is optional, most homeowners obtain a different address for an ADU. If you plan to build an ADU to rent out, it makes sense to have its own address.

If you want more privacy with the type of mail you receive, then sharing the same address with a tenant renting an ADU is not ideal. A local remodeling contractor can construct an ADU and assist you with securing a separate address for it.

Do not limit yourself to looking for contractors in Mountain View. Many construction companies specialize in ADUs in the surrounding cities, and an ADU contractor in San Jose, CA, is capable of building ADUs in Mountain View.

Perks of Having an ADU in Your Home in Mountain View

You should only hire an ADU builder in Mountain View if they have a history of giving excellent service and building high-quality units. These contractors can offer very reasonable prices on fully customized ADUs and have a lot of experience building projects, such as brand-new kitchens, bathrooms, and outdoor patio spaces.

A contractor with wise construction methods can create an ADU that will look beautiful next to your primary residence.

Does an ADU Add Value to Your Home?

An ADU may increase the value of your home and property, and the exact numbers by which it adds value vary. A general contractor can help create an ADU on your property but may not be able to give you an appraisal on your current home.

If you want to learn about your home’s worth after adding an ADU, you should contact a broker or realtor for more information. Besides ADU construction, home renovations can also increase your house’s value. An ADU contractor who’s also a home remodeler can provide the necessary upgrades your house may require.

After constructing an accessory dwelling unit, a home remodeling contractor in Mountain View can make your house the gem of your neighborhood.

Maximizing the Land Available in Your Property in Mountain View

A separate accessory dwelling unit can help you get the most out of the floor space on your land. The value of your property can change if you add more living areas, like a 900-square-foot granny flat, which adds to your house’s total amount of living space. Properties with large backyards are ideal sites for building an ADU.

Rent Out Your ADU in Mountain View

Renting out your ADU is one of the most common and profitable ways to use your new building. The income gained from renting can go toward paying off your current home’s mortgage.

You can maintain the ADU with the additional income earned from renting. With enough time, you can save money and invest in wise remodeling for your house.

What Types of ADU Can You Build In Mountain View?

You can choose from several options, and each homeowner is free to select the ADU that best fits their needs. An experienced ADU builder in Mountain View will look at the space on your land to help you figure out what kind of accessory dwelling unit will best meet your needs.

Here is a brief description of each type of ADU that an accessory dwelling unit contractor can build for you.

Detached ADU Unit

One of the most common types of extra living space is detached ADU units. These units are usually built either next to or behind the main house. Most of the time, a detached unit works best as an extra bedroom that homeowners can rent out to make extra money or accommodate guests.

These detached homes provide plenty of privacy. If you want extra room in your house but not a separate living unit, then consider a contractor who can build an addition to home in Mountain View, California.

Attached ADU Home

Detached ADUs are built separately from a home, whereas contractors build attached accessory dwelling units to the side of a house. A home builder can also construct an ADU above or below a home where a contractor converts the basement. These units must have their entrance but sometimes share a common entry with the primary residence.

ADU Garage Conversion

Homeowners use their garages for parking their vehicles or for storage purposes. Not all people are aware that garages have the potential to be converted into residential homes.

So, if you use ADU garage conversion services in Mountain View, you can turn your existing carport into an ADU by fixing the sidewalls and adding new systems. The best contractors have successfully converted garages into hospitable homes.

Finding the Right Local ADU Builder in Mountain View

You should take your time researching and ensuring that the ADU contractor in Mountain View that you choose meets all the essential criteria because your choice directly affects the development outcome. ADU projects are a considerable investment so take all the time you need to research different contractors.

One method of finding the best contractor is by reviewing their customer reviews. Several organizations award the best construction companies. Reputable companies are well-known in Mountain View and are one of the best ADU homes builders in the SF Bay area.

What to Look for in an ADU Building Company?

Their wide range of experience with similar projects is one of the best signs that firms in ADU Mountain View are reliable and professional. You might also want to check the credentials, insurance, and licenses of the group you hired to work on your project to ensure they are qualified.

All legitimate contractors have portfolios of their completed projects. These pictures and videos can provide insight into the type of work they have done in Mountain View and the surrounding areas.

How Much to Build An ADU?

The size and style of the ADU Mountain View project can have a significant effect on the price. Gathering property details, such as square footage and design ideas for an ADU, is recommended. You should share these details with a contractor so they can provide you with an estimate.

After you gather different estimates for ADU housing construction, you should be able to narrow down your choices that best fit your budget.

Can You Finance an ADU in Mountain View?

Yes! Financing your Mountain View ADU is an intelligent choice that could assist you with completing the project. You can look into ways to get funding, like a home equity loan or line of credit banks offer. This financing option is popular because it lets you use the equity in your house to get money for building an ADU in Mountain View.

Financing options are great for building ADUs and funding home improvement projects like bathroom makeovers in Mountain View, CA.

Process to Build an Accessory Dwelling Unit in Mountain View

You can’t build an ADU alone in Mountain View; you must work with a seasoned accessory dwelling unit builder. Contractors utilize technical skills to create an extremely durable ADU, and their know-how and experience are essential during construction.

Creating a base is the first step in constructing an ADU home. The base holds up the entire structure and guarantees it will remain robust regardless of the environment, making this stage crucial.

The ADU framework will then be raised using the materials of your choosing. Cement and wood are the two primary materials chosen by any construction company. To make your ADU livable, construction crews hire subcontractors that also cover carpentry and the placement of electrical and plumbing components.

Do You Need a Permit for an ADU in Mountain View?

A building permit is necessary for ADUs, but a planning permit is not. The planning staff urges a property owner or designer to submit their suggested ADU design build for approval, and contractors must secure permits. Without permits, homeowners can be fined by a city.

City of Mountain View ADU ordinance

City of Mountain View ADU regulations states that the home may be joined to or separated from the property’s primary residence(s). Moreover, a junior auxiliary dwelling unit (JADU), which is allowed inside a single-family home, is an ADU that is 500 sq ft or smaller in dimension and has an efficient kitchen, with or without sanitation services.

If you are amazed by the kitchen a company builds in an ADU, you should seek kitchen remodel contractors in Mountain View.

Contractors should also be familiar with zoning regulations in Mountain View.
