If you’re a homeowner in Fullerton looking to maximize the potential of your property, building an Accessory Dwelling Unit (ADU) might be the smartest investment you can make. With California’s updated housing laws and the rising demand for flexible living spaces, ADUs have become a popular solution for creating functional, stylish, and high-value additions to residential properties.

What Is an ADU?
An Accessory Dwelling Unit, commonly referred to as an ADU or granny flat, is a fully equipped secondary housing unit built on the same lot as a primary residence. These units come in many forms, including detached backyard cottages, garage conversions, basement apartments, and even additions to the main home. ADUs are designed to be independent living spaces complete with kitchens, bathrooms, and sleeping areas.
Benefits of Building an ADU in Fullerton
ADUs are more than just extra space—they’re a strategic way to:
Generate Rental Income: Earn passive income by leasing the unit to tenants, students, or short-term renters
Support Multigenerational Living: Provide comfortable accommodations for aging parents, grown children, or extended family
Increase Property Value: Boost the resale value of your home with a functional and modern addition
Enhance Property Utility: Use the space for a home office, creative studio, gym, or guest suite
