Finding a Trustworthy Contractor for Your ADU Project

Building an Accessory Dwelling Unit (ADU) can be an excellent way to add value to your property, create additional living space, or generate rental income. However, the success of such a project largely depends on finding a trustworthy contractor who understands your vision and can bring it to life within your budget and timeline. Here’s how you can find a reliable contractor for your ADU project.

1. Clearly Define Your ADU Project

Start with a clear understanding of what you want to achieve with your ADU. Are you looking for a detached unit in your backyard, a garage conversion, or perhaps a basement ADU? Knowing the specifics of your project, including size, design preferences, and functional requirements, will help you communicate your vision more effectively to potential contractors.

2. Research Local Zoning and Building Codes

Any contractor who consults on your project should have knowledge of your jurisdiction and the different zoning and codes that apply to Accessory Dwelling Structures. This knowledge will not only inform the feasibility and specifications of your project but is also a way for the homeowner to  gauge the expertise of potential contractors based on their familiarity with these regulations.

3. Ask for Recommendations

Word-of-mouth is a powerful tool when it comes to finding trustworthy professionals. Ask friends, family, and neighbors if they know any reputable contractors who have experience with ADUs. You can also reach out to local real estate professionals or city planning departments for recommendations.

4. Look for Specialized Experience

Building an ADU comes with its own set of challenges and regulations. It’s important to find a contractor who has specific experience with ADU projects and can navigate the complexities involved. Review their portfolio to see examples of previous ADU projects and ask for references from past clients who had similar work done.

5. Verify Licenses, Insurance, and Credentials

Ensure that any contractor you consider is properly licensed, insured, and, if applicable, bonded. This protects you in case of accidents or damages during the construction process.

6. Assess Communication and Compatibility

The contractor you choose will be a significant part of your life during the construction of your ADU. It’s important that you feel comfortable communicating with them and that they show a genuine understanding of your goals for the project. Assess their professionalism, responsiveness, and willingness to answer your questions thoroughly.

7. Read the Contract Carefully

A trustworthy contractor will provide a detailed contract that outlines the scope of the project, payment schedule, timeline, and how changes to the project will be handled. Review the contract carefully and make sure you understand all the terms and conditions before signing. Don’t hesitate to ask for clarification or amendments if something doesn’t align with your expectations.


Building an ADU is a significant investment and finding the right contractor is crucial to the project’s success. By taking the time to thoroughly vet potential contractors and ensuring clear communication from the start, you can find a trustworthy professional who will help you bring your ADU vision to life. Remember, a good contractor will not only offer quality craftsmanship but also peace of mind throughout the process, making your ADU project a rewarding experience.
