You can make your pre-approved ADU feel like home with various custom touches! While the overall structural plan and layout must stay as designed, you can personalize the look. Choose your favorite paint colors, cabinets, countertops, and interior features. Upgrade the siding, add stylish trims to windows and doors, or swap out outdoor light fixtures to match your aesthetic. Remember that some exterior changes may need additional approval before moving forward.
