Accessory Dwelling Units (ADUs) are gaining popularity as a smart solution for affordable housing, rental income, and multigenerational living. But before you can enjoy the benefits of an ADU, you need to find the right professional to bring your project to life. That’s where an experienced accessory dwelling unit contractor comes in.

What Is an Accessory Dwelling Unit Contractor?

An accessory dwelling unit contractor is a licensed professional who specializes in designing, managing, and constructing secondary housing units on residential properties. Unlike general contractors, ADU specialists have expertise in:

• Local zoning and ADU regulations.

• Designing compact yet functional living spaces.

• Navigating permits and approvals.

• Managing construction within limited property space.

• Coordinating utilities like plumbing, electricity, and HVAC.

They provide a full-service approach, guiding homeowners from the initial consultation to the final inspection.

1. Code Compliance – ADU contractors know your city’s building codes and keep the project legal.

2. Time Efficiency – They streamline the permit and construction process.

3. Cost Control – Contractors minimize costly mistakes by planning ahead.

4. High-Quality Workmanship – They bring experience and skills to every stage.
