§Residential Conversions & ADUs
ADU & Basement Plans
Detached ADUs, garage conversions, and basement living spaces have different zoning, structural, and building-code requirements. We prepare the drawings and engineering included in your scope for the proposed use and property.
ADUs & conversions we help with
Backyard ADUs
Detached living spaces designed for your lot.
Garage conversions
Plans to turn existing garages into living space.
Basement living spaces
Layouts and details for rooms or separate dwellings where permitted.
Attached living units
In-law units and junior ADUs where local rules allow.
