San Mateo homeowners commonly build detached ADUs or garage conversions. Detached ADUs offer the most flexibility for rental income or private living space, while garage conversions are often quicker and more cost-effective since the foundation and some walls are already there. We also see a good number of attached ADUs where space allows. We can help you figure out which type makes the most sense for your property and goals.
