The ADU Pro brings over a quarter-century of expertise to the accessory dwelling unit (ADU) construction industry in Southern California. With more than 30 years under their belt, they’ve established themselves as seasoned professionals in crafting functional and stylish living spaces.

Benefits of Building an ADU

• Increased Home Value: Homes with ADUs can increase their value by 25% or more, particularly in larger cities.
• Rental Income: Your ADU can be a source of passive income. A professional builder can create layouts and amenities to attract tenants.
• Multigenerational Housing: An ADU provides private space and proximity for families, accommodating multiple generations under one roof.
• Open-Living Space: Use the extra space for a home office, guest room, or any purpose you desire.
• Sustainability: Most ADU designs incorporate green technologies, such as energy-saving windows and solar panels, to lower utility costs and reduce your carbon footprint.

Choosing the Right ADU Builder

To realize your ADU concept, consider selecting:

• An ADU builder
• A designer
• An architect
• A consultant
• A general contractor

Working with independent consultants can lead to less accountability and conflicts of interest. It is advisable to work with one design-build ADU builder instead.

When considering the average project size and cost range for The ADU Pro, it’s insightful to look at their permit values. Generally, their projects average around $70,000. However, the investment can vary widely, covering several financial brackets:

• Under $5,000: 1 project
• $5,000 – $20,000: 1 project
• $20,000 – $50,000: 2 projects
• $50,000 – $100,000: 2 projects
• $100,000 – $250,000: 2 projects
• $250,000 – $500,000: 1 project

It’s noteworthy that 10 projects had private values that were not disclosed. These figures illustrate the diverse range of project sizes handled by The ADU Pro, indicating flexibility in accommodating various budgets and needs.

Here’s why:

We will have the same team complete the process on time and within budget, from design to permits and construction. They have precisely the same goals as you, ensuring the entire process is successful and completed quickly.

When embarking on your ADU journey, understanding the process is key. Here’s how a seasoned design-build contractor ensures a seamless experience:

• Design and Planning: The journey begins with a comprehensive design phase. Our experts collaborate with you to draft plans that meet your vision while complying with local regulations.
• Permitting: Navigating permits can be daunting, but our team handles this crucial step, ensuring all paperwork is submitted and approved efficiently.
• Construction: Once permits are in place, construction kicks off. With a dedicated team, we keep the project on track, minimizing delays and ensuring quality craftsmanship.
• Final Sign-Off: The process concludes with a final inspection and sign-off by the city, ensuring your new space is ready for use.

Comprehensive Approach:

This comprehensive approach not only simplifies the process but also ensures that your ADU is tailored to your needs, transforming your backyard with minimal hassle.

Our comprehensive approach begins with a detailed design and planning phase, where we collaborate with you to develop plans that align with your vision. Once the designs are finalized, we take charge of obtaining all necessary permits, navigating the complexities of local regulations to ensure smooth progress.

During the construction phase, our experienced team works diligently to bring your project to life, maintaining clear communication every step of the way. And finally, we handle the final sign-off by city officials, ensuring your new addition is fully compliant and ready for use.

Whether you’re starting from scratch or need us to step in at any stage, our dedicated team is there to support you, transforming your dream into a reality with efficiency and expertise.

Our team excels in maintaining quality by adhering to reasonable timelines and swiftly advancing projects while remaining vigilant about potential challenges. For instance, should any unforeseen delays arise due to weather or emergencies, our team is equipped to address these promptly and effectively, minimizing impact and maintaining momentum.

Furthermore, our professionals bring a personable approach and a wealth of knowledge about building codes and inspections. This expertise not only ensures compliance but also provides peace of mind throughout the construction journey.

Ultimately, our commitment is reflected in the craftsmanship and attention to detail, leaving you satisfied with both the process and the final result.”

If you only employ one seasoned contractor from your area’s ADU builders who provides complete design-build services, you will enjoy a much smoother, more time-efficient process. There is no need to coordinate multiple contractors and experts, which minimizes delays and misunderstandings.

More Hints on Selecting a Pro ADU Builder:

• Check the builder’s license and past ADU projects. Ensure they are familiar with local ADU laws and permits.
• Choose a builder familiar with your municipality’s ADU rules and zoning ordinances.
• Ask the builder about their warranty coverage. Keep a detailed note of what guarantees they offer and how long they last.
• Request quotes from multiple ADU builders to ensure you get an affordable deal.

Types of ADUs

• Detached ADUs: A detached structure from the primary residence, typically located on the side of the home or in the backyard. They provide the most privacy and allow full backyard utilization.
• Attached ADUs: These are attached to the primary residence, often located over the garage or adjacent to the house. They usually have utilities on the same level as the main house, making them less expensive.
• Garage Conversion ADUs: Built by converting garages into homes, these units often consist of living, dining, and kitchen spaces, along with one or more bedrooms and a bathroom. They tend to be cheaper as they utilize existing structures.
• Basement ADUs: This design utilizes the lower levels of your house, providing extra living space without altering the home’s exterior. They generally use the same utilities as your home while offering privacy.
• Junior ADUs (JADUs): Small units housed within or attached to single-family homes, typically created by reconfiguring an attic, basement, or other unconventional space. They usually include a living/sleeping area, a small kitchen, and a bathroom.

Common ADU Floor Plans

The floor plan and design of the ADU will vary depending on homeowners’ requirements. Here are some popular choices:

• Studio Space: A small unit with a living room, bedroom, and kitchen. This minimalist arrangement provides all essentials within a smaller footprint, making it a popular option for small ADUs.
• L-shaped Layout: This layout features a living room that forms an “L” when paired with another functional space, such as the kitchen or bedroom wing. It is usually larger than a linear arrangement and ideal for limited spaces.

Types of ADUs

• 1-Bedroom ADU: This unit features a private bedroom, bathroom, living room, and kitchen. Ideal for a rental property, guest house, single person, or couple.
• Two-Bedroom ADU: This configuration includes two bedrooms, one bathroom, and a living/kitchen space. It can be a single-story or two-story unit, perfect for a small family home or apartment.
• Open Floor Plan: Generally, ADUs have an open floor plan, making an intimate space appear larger and multifunctional.
