Our Recent Projects

Currently, there’s been a rise in the popularity of accessory dwelling units caused by affordable housing shortages and increasing population density in big cities. This flexible housing arrangement allows homeowners to expand their living space without investing too much in a new property or full-fledged construction.

Purchasing an accessory dwelling unit from a reputable contractor enables homeowners to have a new, independent structure where family members can live, work, store their belongings, or rent out in exchange for good earnings. Thus, when initiating an ADU project, it’s vital to find a reliable builder.

This article will explore the intricacies of ADU design projects and introduce ADU Builders Bay Area, a competent ADU design company that will responsibly handle the overall construction process.

Accessory Dwelling Units: Advantages of ADU

Construction

Why set up a supplementary structure, choose a custom ADU design, and integrate the new building into the existing property? In fact, accessory dwelling units may simultaneously serve multiple purposes, and that’s what makes them so versatile and flexible.
So, let’s have a look at some of the popular ADU uses:

  • Additional Living Space for Family Members

Common ADU projects are granny flats and independent units for grown children. If there’s not enough room in the main house, but you have relatives that you don’t want to be apart from, a cozy accessory dwelling unit (a granny flat) just a few steps away from your primary residence is definitely what you need.

  • Backyard Cottage Serving as a Guest House

Inviting friends for the weekend or relatives for family reunions may be quite fun until the time nears a sleepover. Unfortunately, not every house is big enough to have sufficient free rooms and bathrooms to make everyone’s common life comfortable. With an accessory dwelling unit, you don’t need to place an extra mattress in the host’s bedroom or force children to make room for their cousins.

  • Building Accessory Dwelling Units for Work and Hobbies

Sometimes, the reason for building your own ADU in the backyard may be more original. An ADU may be a home office to separate your life from work, a craft space for your home-based business, or just an entertainment room for loud (music composition), messy (e.g., oil painting), or a space-consuming activity (e.g., sports equipment).

  • Rental Unit

Many people build an ADU for the sole prospect of potential revenue. Rental income is a passive income, which means you don’t have to put too much effort into gaining it. Entrust your project to professionals, creating an alluring ADU design that entices potential tenants!

  • Increasing Property Value

Adding an ADU to your property increases its cost. Thus, if selling a piece of land is within your vision, ADU construction may be a solution that brings you up to 30% more revenue.

ADU Project Types

With a good understanding of ADU’s advantages, you’re probably eager to learn about different ADU floor plans. Below, you can find typical ADU plans that contractors offer to select from when envisioning your unit:

  • Detached ADU

Detached ADUs have the same amenities and living facilities as your main house but within a smaller footprint. If traditional homes may reach 2000 sq. ft. and more, the maximum size of detached units is 1000–1200 sq. ft. The key feature of detached ADUs is that they don’t share any physical connection with the primary house and have their own entrance and utilities.

  • Attached ADU

Attached ADU plans are such layouts where an ADU is either a supplemental construction, an extension built as an additional part of the house, or its upper floor. Attached ADUs share at least one wall with the main residence and are self-contained residential spaces equipped with a kitchen, a bathroom, and a bedroom.

  • Converted ADU

Instead of building a new ADU, some property owners opt to transform an existing structure into a livable space. Such examples may include garage conversions, basement or attic conversions, or room conversions. Utilizing more efficient use of existing property, you build your ADU faster, easier, and at a more affordable price.

House owners pick one of the ADU types based on their intended use. But no matter if you want to build a new ADU or convert one of your garages into a nice guest house, you’ll need a professional team to fulfill your desires. Hiring a seasoned ADU contractor who possesses a deep knowledge of the building process will help you determine which one of the ADU types suits your land the most!

Build an ADU with ADU Builders Bay Area

Highly qualified in ADU designing, our team handles every aspect of your ADU project, from the planning and design phase to the building on the property, permission acquisition, and final touches in the interior. Working with our specialists entails close collaboration and open communication when addressing challenging questions.
To complete your ADU design project, we have to go through the following stages:

  1. Discussing your plans

Initially, you’ll meet with expert consultants from ADU Builders Bay Area to determine your goals, the desired ADU type, and your budget. At this stage, you might as well inquire about the company’s credentials and portfolio.

  • Design development

Together with our designer, you’ll work out the interior and exterior design of your ADU. It’s crucial to inform them about your style preferences, color choice, or other specific requirements from the get-go. Despite the fact that there’s an opportunity for future alterations, the initial project is something ADU Builders Bay Area specialists heavily rely on.

  • Permitting Regulations

Before the start of the building, we’ll need to submit ADU floor plans, blueprints, and other documentation to the local authorities. Yet, partnered with ADU Builders Bay Area, you have no reason to worry about this complex process.

  • Construction Phase

Now that we have approved ADU plans, we can commence on-site work. It involves structure building: foundation laying, framing, and erecting walls and a roof. Then follows the installation of windows and doors, the installation of utilities, and the creation of the exterior and interior appearance of the unit.

  • Finishing touches

This is the final phase before the clients will see the results. Thus, we evaluate the completed work and make adjustments, if necessary, ensuring that everything complies with laws, safety rules, and the client’s wishes.

Frequently Asked Questions — FAQ

Can I design my own ADU?

Certainly, this is an option. If you familiarize yourself with ADU regulations and permitting processes, as well as the challenges and stages of ADU building, you can design and build a new ADU on your own. However, if you think you're lacking knowledge in the field, you can apply for professional assistance. By collaborating with a competent designer, you can state your requirements as to layout, size, number of rooms, style preferences, and other factors that you deem vital.

Is building an ADU worth it?

Building an ADU allows you to gain in many aspects. You can increase your property value and sell your land with the ADU on it. You can rent it out and receive a monthly income. You might as well use it as a nice backyard cottage to rest, do your hobbies or work. Lastly, you can accommodate guests or family members in this fully-equipped unit.

Is a prefab ADU better than a custom-built one?

Prefab units are pre-made units with standard layouts and designs. They are sometimes cheaper, easier, and quicker to construct. On the contrary, if you create an ADU from scratch, you have more creative freedom, but at the same time, such projects may consume more time and money. Yet, if you've always dreamt of a custom design, ADU Builders Bay Area will assist you in planning your budget and selecting more affordable materials while not compromising quality.
