What's a good size for an ADU?

The size is an important consideration you need to make early in the ADU design process. The number of bedrooms you want and the desired spaciousness of the living areas are both factors to consider. However, it's important to also balance these preferences with the overall ADU cost, including construction and fees. At SnapADU, we offer guidance on the various sizes to consider for your ADU design. Our team can help you determine the optimal size for your specific needs and budget. Keep in mind that larger ADUs may be more expensive to build, but they may also provide more value and flexibility in the long run. Ultimately, the size of your ADU will depend on your personal preferences and goals.
