ADU Builders are becoming a popular choice for homeowners in the Phoenix area looking to expand their living spaces. These Accessory Dwelling Units, or ADUs, offer versatile solutions for various housing needs. Whether you’re seeking extra space for multigenerational living, a guest house, or a rental unit to generate additional income, ADUs can significantly improve the functionality and value of your property.
Here are three key reasons to consider building an ADU:
-
Housing Needs: ADUs provide a flexible living option for accommodating family members, guests, or even a home office.
-
Rental Income: By renting out an ADU, homeowners can earn a steady stream of rental income, potentially offsetting mortgage costs.
-
Property Value: An ADU can increase your property’s value by adding functional living space without the need for purchasing additional land.

What is an ADU and Why Consider Building One?
An Accessory Dwelling Unit (ADU) is a secondary residential unit located on the same lot as a primary home. These units are a fantastic way to add additional space to your property without the need for extensive land purchases or major infrastructure changes. Whether you want to create a cozy guest house, an in-law suite, or a rental unit, ADUs offer a versatile solution.
Why Consider Building an ADU?
1. Flexibility and Functionality
ADUs provide flexible living options. They can be used to house family members, offer a private space for guests, or serve as a home office. This flexibility is invaluable for families needing extra space without the hassle of moving or undergoing major renovations.
2. Revenue Generation
Building an ADU can be a smart financial move. Renting out the unit can generate a steady income stream, potentially offsetting your mortgage or other expenses. According to recent data, homeowners can earn up to $2,500 a month by renting out their ADU, making it a lucrative investment.
3. Boost in Property Value
Adding an ADU can significantly increase your property’s value. By expanding your living space, you improve the overall appeal and functionality of your home. This can lead to a property value increase of up to 35%, according to some estimates.

ADUs are not just about adding space; they are about enhancing lifestyle and property value. With the right planning and execution, an ADU can transform your living situation and offer financial benefits. As Richard Garrett of RG ProBuilders puts it, “ADUs are a game-changer for homeowners looking to maximize their property’s potential.”
Next, let’s explore how to choose the right ADU builders for your project.
How to Choose the Right ADU Builders?
Selecting the right ADU builders is crucial to ensure a successful project. Here’s what to consider when making your choice:
1. Proven Reliability
Look for builders with a strong track record in constructing ADUs. Experience matters, as it ensures familiarity with the unique challenges these projects present. A reliable builder will have a portfolio of completed projects and positive reviews from homeowners. For instance, RG ProBuilders, a well-regarded ADU builder, has completed numerous ADUs in Arizona, demonstrating their expertise and reliability in the field.
2. Personalized Service
Every homeowner has unique needs. A good ADU builder understands this and offers personalized service custom to your specific requirements. They should be open to customization, allowing you to design an ADU that fits your lifestyle and preferences. As noted in the research, “No Cookie Cutter ADUs Here – Each One is Uniquely Yours,” emphasizing the importance of a personalized approach.
3. Navigating Construction Complexities
Building an ADU involves navigating various construction complexities, including permits, zoning laws, and utility connections. Choose a builder who is well-versed in these areas and can handle the intricate details of the process. They should assist with obtaining necessary permits, which can take 3-5 months, and ensure compliance with local regulations.
“Building an ADU comes with its own set of challenges and regulations,” notes a source from RG ProBuilders. “It’s important to find a contractor who has specific experience with ADU projects and can steer the complexities involved.”
4. Comprehensive Project Management
Select builders who offer comprehensive project management services. This includes everything from the initial design phase to final construction. A dedicated project manager can streamline the process, ensuring that your ADU is built efficiently and to high standards.
5. Strong Communication
Effective communication is key to a successful construction project. Your builder should be responsive, keeping you informed at every stage and addressing any concerns promptly. Assess their professionalism and willingness to answer questions thoroughly.
By choosing the right ADU builders, you ensure a smooth construction process and a final product that meets your expectations. Next, we’ll look at the costs involved in ADU construction, helping you plan your budget effectively.
What Are the Costs Involved in ADU Construction?
Building an Accessory Dwelling Unit (ADU) involves several costs, and understanding these can help you plan your budget effectively. Let’s break down the main expenses:
Construction Permits
Before you start building, you’ll need to obtain construction permits. These permits are essential for ensuring your ADU complies with local zoning and building codes. The permit process can take between 3 to 5 months, depending on the city. It’s crucial to factor in this time and cost when planning your ADU project. Your builder should assist you in navigating this process, ensuring all necessary permits are secured efficiently.
Housing Costs
The cost of constructing an ADU varies based on size, location, and materials. Generally, detached ADUs tend to be more expensive due to the need for additional infrastructure, like separate utilities. On the other hand, garage conversions are typically more affordable. While the initial investment can be significant, an ADU can increase your property’s value by up to 25% – 35% and provide a steady rental income.
Affordable ADU Builders
Finding an affordable ADU builder is key to managing costs. Look for builders who offer transparent pricing and have strong relationships with manufacturers to keep material costs down. A reliable builder will provide a detailed breakdown of costs, so you know exactly what you’re paying for. They should also offer financing options or guide you to resources that can help fund your project.
“Choosing the right builder can make a significant difference in the overall cost of your ADU,” emphasizes a source from RG ProBuilders. “Affordable builders not only offer competitive rates but also ensure quality craftsmanship.”
By understanding these costs and working with experienced ADU builders, you can make informed decisions and maximize the return on your investment. Next, let’s explore the timeline for building an ADU, so you know what to expect in terms of project duration.
How Long Does It Take to Build an ADU?
Building an Accessory Dwelling Unit (ADU) involves several stages, each crucial to completing your project. Here’s a breakdown of the typical timeline:
120 Days from Permit Approval
Once you have your permits in hand, construction can begin. The process typically takes about 120 days from this point. This timeframe is an average, and actual times can vary based on factors like weather conditions, the complexity of the design, and the efficiency of your builder.
Construction Timeline
The construction phase is where your ADU takes shape. It generally lasts between 3 to 4 months. During this period, your builder will handle everything from laying the foundation to installing utilities and finishing touches. A streamlined process with clear milestones helps keep the project on track. It’s essential to have regular updates from your builder to ensure everything is progressing as planned.
Project Completion
After construction, there are a few final steps before your ADU is ready for occupancy. These include inspections to ensure compliance with all building codes and regulations. Once the inspections are complete, you can move in or start renting out your new space.
Working with experienced ADU builders can significantly impact the efficiency and quality of your project. Their expertise ensures that potential delays are minimized, and your ADU is completed to the highest standards.
With a clear understanding of the timeline, you’re better prepared for the journey of building an ADU. Now, let’s explore the exciting design options available for your new space.
What Are the Design Options Available for ADUs?
When it comes to designing your Accessory Dwelling Unit (ADU), there are several options to consider. Whether you need a cozy studio or a spacious three-bedroom unit, choosing the right design is crucial to meet your needs and maximize your property’s potential.
Studio ADUs

Studio ADUs are perfect for those seeking a compact and efficient living space. Typically under 400 square feet, these units are ideal for minimalists or those looking for an affordable housing option. Studios offer a single open space that combines sleeping, living, and kitchen areas, making them a versatile choice for guests or short-term rentals.
1 Bedroom ADUs

A one-bedroom ADU offers a bit more privacy and space. These units usually range from 375 to 660 square feet, providing a separate bedroom along with a combined living and kitchen area. A one-bedroom ADU is great for a single occupant or a couple, offering a balance between space and affordability.
2 Bedroom ADUs

For those needing more room, a two-bedroom ADU is a practical choice. With sizes typically around 800 to 900 square feet, these units provide ample space for a small family or roommates. A two-bedroom ADU can also be an excellent option for aging parents or adult children who need a little extra room while still maintaining proximity to the main home.
3 Bedroom ADUs
Three-bedroom ADUs offer the most space, often reaching up to 1,200 square feet. These units are perfect for larger families or those who plan to use the ADU for long-term rental income. A three-bedroom setup provides all the comforts of a full-sized home, including multiple bathrooms and spacious living areas.
Customization and Personalization
No matter the size, each ADU can be customized to fit your style and needs. From choosing designer-approved finishes to adjusting floor plans, the possibilities are endless. Working with experienced ADU builders ensures that your unit is not just functional but also uniquely yours.
With a variety of design options available, you can select an ADU that perfectly complements your lifestyle and improves your property’s value. Now that you know the design possibilities, let’s dive into the legal requirements for building an ADU.
What Are the Legal Requirements for Building an ADU?
Building an Accessory Dwelling Unit (ADU) involves navigating several legal requirements. Understanding zoning changes, owner-occupancy requirements, and building lot restrictions is essential for a smooth construction process.
Zoning Changes
Zoning laws are a crucial factor when planning to build an ADU. These laws dictate where ADUs can be constructed and often include specific guidelines on size and location. For instance, some areas may limit the size of an ADU to a certain percentage of the main home or set a maximum square footage. It’s important to check with your local zoning office or consult with professional ADU builders to understand the specific regulations in your area.
Owner-Occupancy Requirements
Owner-occupancy requirements can affect your ability to build an ADU. In some regions, the homeowner must live on the property, either in the main house or the ADU. However, recent reforms in places like California have relaxed these rules, leading to a significant increase in ADU construction. While these changes have not been universally adopted, they highlight a trend towards more flexible regulations. Always verify current requirements in your locality to ensure compliance.
Building Lot Restrictions
The size and layout of your building lot can also impact your ADU project. Lot size, setbacks, and existing structures are all considered in determining where and how an ADU can be built. Some areas might require a minimum lot size or specific setbacks from property lines. Working with experienced ADU builders can help you steer these restrictions and optimize your lot for construction.
Understanding these legal requirements is crucial for a successful ADU project. With the right information and professional guidance, you can ensure your ADU is compliant and ready to improve your property. Next, we’ll address some frequently asked questions about ADU builders to further assist you in your journey.
Frequently Asked Questions about ADU Builders
What is the average size of an ADU?
The size of an Accessory Dwelling Unit (ADU) can vary based on local zoning laws and your specific needs. Typically, ADUs range from 150 square feet to 1,200 square feet. This flexibility allows homeowners to choose a size that fits their property and lifestyle. Smaller ADUs, like a studio or one-bedroom, are perfect for single occupants or couples. Larger units, with two or three bedrooms, can accommodate families or provide more rental income potential. Always consult with professional ADU builders to determine the best size for your project.
Can I rent out my ADU?
Yes, you can rent out your ADU, and it can be a great way to generate additional income. Many homeowners earn up to $2,500 per month by leasing their ADUs. However, rental regulations can vary by city. Some places may have restrictions on short-term rentals, like Airbnb, requiring rentals to be for 30 days or longer. It’s essential to check local rental rules and consult with experienced ADU builders to ensure compliance with these regulations.
Are there any tax benefits to building an ADU?
Building an ADU can impact your property taxes. In many areas, taxes increase only on the new unit, not the main home. Typically, the tax increase is around 1–1.5% of the ADU’s assessed value. For example, a $200,000 ADU might add $2,000 to $3,000 to your annual property taxes. However, California’s Prop 13 law caps future annual increases at 2%. It’s advisable to consult with a tax professional to understand the specific tax implications for your property.
By understanding these aspects, you can make informed decisions about building and renting an ADU. Next, we’ll conclude with how RG ProBuilders can assist you in your ADU journey in Phoenix, Arizona, and surrounding areas.
