Step-by-Step Guide to Building Your First ADU
Creating an accessory dwelling unit (ADU) is one of the best ways to add space, increase property value, or generate rental income. But for first-time builders, the process can seem overwhelming. At MF ADU, we make it easy by guiding homeowners through every stage—from initial planning to move-in day.
Step 1: Understand What’s Allowed on Your Property
Before you begin, it’s important to know what your city allows. California’s ADU laws are flexible, but zoning rules can still vary by location. We help you review:
Minimum lot sizes
Setback requirements
Maximum square footage
Parking and height limits
Understanding these early ensures your project starts on the right track.
Step 2: Choose the Right ADU Type
ADUs come in several forms: detached backyard units, attached additions, garage conversions, and more. We help you decide which type fits your property layout, budget, and goals. Prefabricated options often make the process faster, easier, and more cost-efficient.
Step 3: Design and Customize Your ADU
Once the ADU type is chosen, it’s time to design. You can personalize layouts, finishes, and energy-efficient features to match your lifestyle. At MF ADU, our design team focuses on creating comfortable, functional spaces with modern aesthetics that complement your main home.
Step 4: Secure Permits and Approvals
Permitting is often the most confusing step for first-time builders. Our team handles the process for you, ensuring all plans meet California’s building codes and local zoning requirements. This saves time and prevents costly revisions later in the project.
Step 5: Construction and Installation
After permits are approved, construction begins. For prefabricated ADUs, the unit is built off-site while your property’s foundation is prepared. Once delivered, installation and finishing take only a few weeks. The result is a high-quality, durable home ready for living or renting.
