MULTI-FAMILY ACCESSORY DWELLING UNITS (ADU)
California State Regulation GC 65852.2 adopted by local ordinances allows for accessory dwelling units added on multi-family buildings. This regulation allows the asset owners to:
- Increase the property’s NOI at a favorable cost basis
-
Achieve market rents on the additional units at a sizeable return on cost (ROC)–typically between 8%-15%
-
Owners can increase the resale value with entitled ADU plans
-
Choose to do permitting, construction, or full service design / build with Biayna in one stop"
