Building a DADU is a significant investment, and understanding where the money goes is one of the most powerful tools a homeowner has. That’s why we break DADU construction costs into clear, manageable phases—so consumers can budget accurately, understand how decisions affect pricing, and feel confident at every step of the process. Transparency around costs provides real agency: when you know what to expect, you can plan ahead, ask the right questions, and avoid surprises. With the right education, homeowners often save thousands by making informed choices early, selecting the right trade-offs, and navigating the build process with clarity rather than guesswork.
