Slashing Permitting Timelines with Code-Ready ADU Layouts
Custom architecture is beautiful, but it often introduces severe bureaucratic friction and prolonged municipal review cycles.

These layouts have already been optimized for Title 24 energy efficiency, strict wildland-urban interface (WUI) fire separations, and optimal plumbing manifold routing—saving you thousands in preliminary architectural fees.
