Sacramento ADU Builders
Sacramento pairs California's statewide ADU laws with costs below the coast. Local firms advertise fixed, all-in pricing, deep fluency in state ADU law (SB 9, Title 24 energy), and structural warranties.

Cost basics
Detached ADU projects commonly run $150,000–$400,000+ depending on size and finishes; garage conversions cost less. Builders focused on the Sacramento area can give project-specific pricing — several publish real example budgets on their profiles.
Permit basics
State law requires by-right approval of compliant ADUs in most cases, but local rules (setbacks, height, parking, historic districts) vary. Confirm requirements with your city's planning department before finalizing a design — or ask a local design-build firm, which handles permitting as part of the project.
