Allowed ADU Types
ADUs are permitted by right on all residential lots per state law. Victorville's desert high-altitude climate and lower land values make it one of the most affordable ADU markets in Southern California. The city uses R-1L (Low Density) and RL (Rural Low) designations for larger-lot estate areas at the city's periphery.
