They bridge the gap between initial architectural designs and the final move-in date for your new space.
While ADUs offer many advantages, potential disadvantages include the initial construction costs and the possibility of increased utility expenses. It's also important to comply with local zoning regulations and any homeowner association rules. Professional guidance can help address these concerns proactively.
