Thorough investigation of the specific zoning codes applicable to Warren is a critical prerequisite for any ADU development. The existing housing stock, largely composed of single-family homes built during various decades, offers substantial potential for ADU construction, particularly through garage conversions or the addition of backyard cottages.
