The cost of building an ADU in California can vary widely depending on several factors, including size, design, and amenities.

Why Urban Custom ADU Builders Matter

Building your dream ADU is exciting, but let’s talk about the elephant in the backyard—how to pay for it. While custom ADU builders create spaces that perfectly match your vision, understanding your financing options will help turn those plans into reality without unnecessary financial stress. Custom ADU builders also excel at navigating the maze of local building codes. They design with your specific city’s requirements in mind from day one, rather than trying to adapt a prefabricated design that might need costly modifications to meet local standards. These often serve as homes for extended family members or may be rented out to provide the homeowners with an additional source of income.
