This unique characteristic means that ADU contractors working in Orange must navigate not only standard California state ADU regulations but also local historic preservation guidelines when projects fall within or near the Old Towne Historic District. Homeowners in these areas may face additional design review requirements to ensure that any accessory dwelling unit complements the architectural character of the surrounding neighborhood.

Projects within the Old Towne Historic District may require additional review by the Old Towne Historic Preservation Committee.
