Building an ADU with Greenwood Contractors: A Comprehensive Guide
At Greenwood Contractors, we specialize in making the process of designing and building an Accessory Dwelling Unit (ADU) seamless, efficient, and stress-free. Whether you’re adding a guest house, rental unit, or extra space for family, we guide you through every step to ensure a high-quality outcome tailored to your needs.
What Is An Adu?
An ADU (Accessory Dwelling Unit) is a secondary residential unit on a property with an existing home. It can be detached, attached to the main home, or even a garage conversion. ADUs are an excellent way to maximize your property’s value, generate rental income, or create flexible living arrangements.

Our Step-by-Step Process
Consultation & Feasibility Study
We begin with a detailed consultation to understand your goals and vision. Our team assesses your property to determine feasibility, including zoning laws, lot size, and building codes in your area.
Design & Planning
Our architects and designers collaborate with you to create a functional, aesthetically pleasing ADU design that complements your main home. We ensure all designs comply with local regulations while reflecting your unique style.
Permitting & Approvals
Navigating permits and approvals can be complex. Our team handles all paperwork, ensuring your project meets city and state requirements, so you don’t have to worry about delays.
Construction
Once permits are approved, our skilled builders bring your ADU to life. From laying the foundation to final finishes, we use only high-quality materials and craftsmanship to deliver a durable and beautiful structure.
Final Inspections & Handover
After construction, we conduct thorough inspections to ensure everything meets code and exceeds your expectations. Once approved, we hand over your brand-new ADU, ready for use.
